INTRODUCTION Thank you for choosing Harman Kardon!! With thepurchase of a Harman Kardon®AVR 745, you areabout to begin many years of listening enjoyment.The AVR 745 has the most extensive range of audioand video processing, control and connectivity optionsever offered by Harman Kardon, enabling it to providethe best possible audio and video reproduction withany type of source material. Teaming advanced pro-cessing circuitry with proprietary technologies such asEzSet/EQ II, the AVR 745 seamlessly integrates everycomponent in your entertainment system to deliver thebest possible sound and images.Some of the leading-edge features that are availablewith the AVR 745, such as HDMI™connectivity,XM-Ready®operation, DCDi by Faroudja®video processing with upscaling to 1080i, and the TC 30activity-based remote, are new to even the most expe-rienced home theater enthusiast. Although the powerof the AVR 745 makes them easy to use, we stronglyrecommend that you take a few minutes to read thisowner’s manual to familiarize yourself with how the fullsuite of AVR 745 features and capabilities are config-ured and used in day-to-day operation. This smallinvestment of time will yield significant dividends intaking the maximum advantage of this new addition to your home theater system.If you have any questions about this product, its instal-lation or its operation, you may also access a wealthof information and assistance by visiting our Web siteat www.harmankardon.com.Description and FeaturesThe AVR 745 serves as the hub of your home enter-tainment system, providing a wide range of listeningpossibilities for almost any audio or video programsource, whether it is the broadcast of a movie orsporting event in HDTV or a vintage mono or stereorecording.When playing digital audio sources fromeither the conventional optical and coaxial inputs, orthrough the HDMI 1.1 compliant connections, theAVR 745 decodes Dolby Digital, Dolby Digital EX,DTS and DTS-ES data streams. Two-channel stereoand matrix surround sources benefit from all currentDolby Pro Logic IIx modes and DTS Neo:6. The latestversion of our proprietary Logic 7®process is on-board to create a wider, more enveloping sound fieldand more defined surround channel positioning,regardless of the type of source material. Additionalaudio playback and processing options include adirect connection to compatible computer-basedsources through a direct USB connection.The AVR 745 takes the “video” part of its name seri-ously. Along with two HDMI inputs and three 100MHzanalog component video inputs, the AVR 745’s videoprocessing allows you to individually adjust the videoprocessing parameters for each input, and then scalethe output signal to 720p or 1080i to match therequirements of your specific video display. Thanks to award winning Faroudja®technology, your videosources never looked better. Tying audio and videotogether, the AVR 745 provides A/V sync delay so thatthe lip sync errors – commonly seen when digitalvideo processing is used in a source, program orvideo display – are eliminated.Thanks to a wide range of multizone options and astandard ZR 10 remote control, the AVR 745 makes it possible to watch and listen to a separate source inone room while the main home theater uses a differ-ent source. Using the assignable rear surround chan-nel amplifiers, you may create a basic remote listeningzone without any additional equipment, or the unit’smultiroom outputs may be used to feed an optional,external power amplifier and volume control. For one-wire multiroom connectivity, the AVR 745 is A-BUS/READY®, requiring only a single Category 5/5ecable run and an optional remote module to power apair of remote speakers while controlling volume andenabling full control over the program source and connected IR-controlled devices.Along with the latest advances in digital audio andvideo technology, Harman Kardon recognizes thatsome things remain constant, and in the case of theAVR 745 that is a requirement for audio power bestserved by our time-honored high-current, ultrawidebandwidth amplifier design. The AVR 745’s seven-channel amplifier provides the power to reproduce theloudest crescendos or cinema sound effects whileremaining virtually free from distortion or system noise.With a combination of state-of-the-art circuitry,digitaltechnology and proven performance with an elegantdesign that is compatible with the latest source com-ponents and video displays,the AVR 745 representsthe culmination of Harman Kardon’s fifty-plus year history of delivering the finest sonic performance.ÍÍAll popular digital and matrix surround modes,including Dolby®Digital, Dolby Digital EX,Dolby Pro Logic®II, DTS®, DTS-ES®Discrete andMatrix, DTS Neo:6®and DTS 96/24®ÍÍSeven channels of high-current, ultrawide band-width amplification with the surround back channelsassignable to either main-room or remote-room useÍÍHarman Kardon’s Logic 7®processing brings a newsense of reality to stereo and matrix surroundsourcesÍÍDolby Virtual Speaker processing for use when lessthan a full 5.1 or 7.1 speaker complement is available ÍÍDolby Headphone for spacious, open sound fieldswhen using headphonesÍÍUSB connectivity for audio playback with compatiblecomputers and quick system upgradesÍÍTwo HDMI™1.1 and three assignable high-band-width analog component inputs for compatibilitywith the latest high-definition video sources ÍÍFull bass management for all inputs, including the analog direct inputs for high-resolution DVDs,DVD-Audio and SACD™players, including QuadCrossover settings and individual settings for each inputÍÍDual subwoofer outputs for 7.2 operation withimproved low-frequency performanceÍÍA/V sync delay adjustable for each input deliversperfect lip sync with digital programs or video displaysÍÍFront-panel digital audio and analog audio/videojacks may be used as either inputs or outputs forconnection to the latest portable digital products orvideo game consolesÍÍExtensive multiroom options, including a standardZR 10 remote, audio and video outputs to theremote zone, assignable rear channel amplifierchannels and A-BUS/READY®capability for listeningto a separate source in a remote zoneÍÍHarman Kardon’s TC 30 activity-based remote withcolor LCD screen for total system controlINTRODUCTION 3AVR 745 OM 5/15/06 5:00 PM Page 3

In conformance with theCEA color-code specification, the green terminal is thepositive (+) terminal that should be connected to thered (+) terminal on speakers with the older color-cod-ing. Connect the black (–) terminal on the AVR to theblack negative (–) terminal on your speaker. (Seepage 15 for more information on speaker polarity.)ESurround Back/Multiroom Speaker Outputs:These speaker terminals are normally used to powerthe surround back left/surround back right speakers in a 7.1-channel system. However,they may also beused to power the speakers in a second zone, whichwill receive the output selected for a multiroom system.To change the output fed to these terminals from the default of the Surround Back speakers to theMultiroom Output, you must change a setting in theAdvanced Menu of the OSD system. See page 51 formore information on configuring this speaker output.In normal surround system use, the brown and blackterminals are the surround back left channel positive(+) and negative (–) connections and the tan andblack terminals are the surround back right positive(+) and negative (–) terminals. For multiroom use,connect the brown and black SBL terminals to the red and black connections on the left remote zonespeaker and connect the tan and black SBR terminalsto the red and black terminals on the right remotezone speaker.FIR Input: If the AVR 745’s front-panel IR sensoris blocked due to cabinet doors or other obstruc-tions, an external IR sensor may be used. Connectthe output of the sensor to this jack.GSwitched AC Accessory Outlet: This outlet maybe used to power any device you wish to have turnedon when the AVR 745 is turned on with the Standby/On Switch 1.IMPORTANT NOTE: The power consumption of anydevice connected to the accessory outlet should notexceed 100 watts.

INSTALLATION AND CONNECTIONSSystem InstallationAfter unpacking the unit, locating it in a place with ade-quate ventilation and placing it on a solid surface capableof supporting its weight, you will need to make the con-nections to your audio and video equipment.Before starting to connect your AVR 745 to thesource devices, display device, speakers and othercomponents in your system, you should also unpackthe TC 30 remote, which is found in the separate boxinside the AVR 745 carton. So that the TC 30 is readywhen you begin the system configuration process,install the battery, connect the charger and place theremote in the charging cradle, as it takes approximatelytwelve hours for the battery to fully charge.IMPORTANT NOTE: For your personal safety and toavoid possible damage to your equipment and speakers,it is always good practice to turn off and unplug the AVRand ALL source equipment from the AC output beforemaking any audio or video system connections.Audio Equipment ConnectionsWe recommend that you use high-quality interconnectcables when making connections to source equipmentand recorders to preserve the integrity of the signals.1. Connect the analog output of a CD player to theCD Audio Inputs 6.NOTE: If your CD player has both fixed and variableaudio outputs, it is best to use the fixed output unlessyou find that the input to the receiver is so low that thesound is noisy, or so high that it is distorted.2. Connect the analog Play/Out jacks of a cassettedeck, MD, CD-R or other audio recorder to the Tape Inputs 4. Connect the analog Record/Injacks on the recorder to the Tape Outputs 2on the AVR 745.3. Connect the output of a digital source such as a CD or DVD changer or player, a video game, a digital satellite receiver, an HDTV tuner or digital cable set-top box or the output of a compatiblecomputer sound card to the Optical and CoaxialDigital Audio Inputs deKM.4. Connect the coaxial or optical Digital Audio Outputsab on the rear panel of the AVR 745 to the match-ing digital input connections on a CD-R, MiniDisc orother digital recorder.5. Assemble the AM loop antenna supplied with the unitso that the tabs at the bottom of the antenna loopsnap into the holes in the base. Connect it to the AMAntenna Connections l.6. Connect the supplied FM antenna to the FMAntenna Jack k. The FM antenna may be an external roof antenna, an inside powered orwire-lead antenna or a connection from a cable TV system. If the antenna or connection uses 300-ohm twin-lead cable, you must use an optional300-ohm-to-75-ohm adapter to make the connection.7. Connect the front, center, surround and surroundback speaker outputs 57DE to the respec-tive speakers.To ensure that all the audio signals are carried to yourspeakers without loss of clarity or resolution, we sug-gest that you use high-quality speaker cable. Manybrands of cable are available and the choice of cablemay be influenced by the distance between yourspeakers and the receiver, the type of speakers youuse, personal preferences and other factors. Your dealer or installer is a valuable resource to consult inselecting the proper cable.Regardless of the brand of cable selected, we recom-mend that you use cable with a gauge of 14 or smaller.Remember that when specifying cable,the lower thenumber, the thicker the cable.Cable with a gauge of 16 may be used for short runsof less than 10 feet. We do not recommend that youuse cables with an AWG equivalent of 18 or higher,due to the power loss and degradation in performancethat will occur.Cables that are run inside walls should have the appro-priate markings to indicate listing with UL, CSA or otherappropriate testing agency standards. Questions aboutrunning cables inside walls should be referred to yourinstaller or a licensed electrician who is familiar with the NEC and/or the applicable building codes in your area.When connecting wires to the speakers, be certain to observe proper polarity.Note that the positive (+)terminal of each speaker connection has a specific colorcode, as noted on page 8. However, most speakersstill use a red terminal for the positive (+) connection.Connect the “negative” or “black” wire to the same terminal on both the receiver and the speaker.NOTE: While most speaker manufacturers adhere toan industry convention of using black terminals fornegative and red ones for positive,some may varyfrom this configuration. To ensure proper phase andoptimal performance, consult the identification label onyour speaker or the speaker’s manual to verify polarity.If you do not know the polarity of your speaker, askyour dealer for advice before proceeding, or consultthe speaker’s manufacturer.We also recommend that the length of cable usedto connect speaker pairs be identical. For example,use the same length piece of cable to connect thefront-left and front-right or surround-left and sur-round-right speakers, even if the speakers are a different distance from the AVR 745.8. Connections to a single subwoofer are normallymade via a line-level audio connection from theMain Subwoofer Output 1to the line-level inputof a subwoofer with a built-in amplifier. When apassive subwoofer is used, the connection firstgoes to a power amplifier, which will be connectedto one or more subwoofer speakers. If you areusing a powered subwoofer that does not haveline-level input connections, follow the instructionsfurnished with the speaker for connection informa-tion. If your system uses two subwoofers, connectthe Subwoofer 2 Output 9jack on the AVR tothe Line Input of the second subwoofer.9. If an external audio source such as a DVD-Audio,SACD or high definition optical disc player with 5.1or 7.1 analog audio outputs is part of your system,connect the outputs of the source to the 8-ChannelDirect Inputs f.Analog Video Equipment ConnectionsAnalog video components are connected in the samemanner as audio components. Again, the use of high-quality interconnect cables is recommended to preserve signal quality.1. Connect the Video Play/Out jacks of a standard(composite) video or S-Video outputs of a digitalvideo recorder or conventional VCR to the Video 1Video Inputs Ton the AVR. Connect theRecord/In jacks from that device to the Video 1Video Outputs Uon the AVR.2. Connect analog Audio Left/Right Play/Out jacks ofthe device connected to the Video 1 Inputs to theVideo 1 Audio Inputs gon the AVR. Connectthe analog Audio Left/Right Record/In jacks fromthat device to the Video 1 Audio Outputs jonthe AVR. If the device has a digital audio output,connect it to one of the Coaxial dor Optical edigital audio inputs.3. Connect the Play/Out jacks of a standard (compos-ite) video or S-Video outputs of a video playbacksource such as a set-top box or video game con-sole to the Video 2 Video Inputs Vor Video 3Video Inputs W.If the device has analog compo-nent video (Y/Pr/Pb) outputs, connect them to oneof the Component Video Inputs Q.4. Connect the analog audio outputs from the sourceto the matching Video 2 Audio Inputs iorVideo 3 Audio Inputs h.If the device has a digi-tal audio output, connect it to one of the Coaxialdor Optical edigital audio inputs.5. If the any of the video source devices has analogcomponent video (Y/Pr/Pb) outputs, but not HDMI,connect them to Component Video Inputs Q.The chart on page 55 has the default settings forINSTALLATION AND CONNECTIONS 15AVR 745 OM 5/15/06 5:00 PM Page 15
16 INSTALLATION AND CONNECTIONS16 INSTALLATION AND CONNECTIONSINSTALLATION AND CONNECTIONSvarious source devices, but you may make anyconnection and change the configuration settingusing the IN/OUT SETUP menu, asdescribed on page 22.6. The default video connection for a DVD player is touse the Component Video Input 3 Jacks Qonthe AVR, but you may change this assignment inthe IN/OUT SETUP menu (see page 22).A DVD player’s composite and S-video outputs mayalso be connected to the DVD Video Inputs S.Only one connection type is required, although acomposite or S-video connection is required if theAVR 745 is to be used in a multiroom video system.7. The default audio connection for a DVD player is to link the coaxial digital audio output on the DVDplayer to the Coaxial 1 Digital Audio Input d,but you may also make a connection to either theCoaxial dor Optical edigital inputs, or theAnalog DVD Audio Inputs c.You may changethe assignment in the IN/OUT SETUPmenu as described on page 22, or by using thefront-panel Digital Input Selector F.8. If you wish to use a portable audio/video productsuch as a camcorder, portable media player or digital still camera with the AVR, or make a connec-tion to a video game console or other source thatmay not always be connected to the AVR, connectthe video outputs of the source to the Video 4Input/Output Jacks Nthat are behind theFront-Panel Door 8. If the source has digitalaudio outputs, connect them to the Optical 4Digital Input Kor the Coaxial 4 Digital Jack M.CONNECTION NOTES:• When making connections to the ComponentVideo Inputs Qor the Coaxial dor Opticaledigital audio inputs, it is a good idea to makenote of which jacks are connected to whichsource, using the Worksheet in the Appendix. Thiswill help simplify the configuration process.• When connecting a source device such as acable set-top box where the audio streams maychange between digital and analog as youchange channels, we recommend that you makeboth analog and digital connections. The AVR’sAuto Poll feature will automatically sense whenthe digital stream is replaced by an analog outputand switch the input accordingly. (See page 22for more information on the Auto-Poll feature.)This dual connection is not required for sources(such as DVD players or video games) that alwaysoutput a digital stream.9. Connect the AVR to your video display using one ofthe following connections:• If you have a video display with an HDMI or DVIinput, make the connection using the HDMIOutput d, as described in the next section.• If your video display has component video inputs(Y/Pr/Pb), connect the Component VideoOutputs O.• If your display does not have digital or compo-nent video inputs, connect the Video MonitorOutput Ron the AVR to the matching input onyour display. Only one connection is needed, andS-video is the higher quality signal.HDMI ConnectionsHDMI™is the abbreviation for High-DefinitionMultimedia Interface, which is quickly becoming the standard connection point between advancedvideo/audio source products and displays, particularlyfor high-definition video signals. HDMI is a digital con-nection, eliminating the need to convert signals backand forth from digital to analog to deliver a higherquality signal when used with digital sources. The sig-nals carried on HDMI may, but do not always, includeaudio, offering the possibility of a complete one-wireconnection from a source to the AVR. However, it isimportant to note that there are a number of differentversions of the HDMI standard in use. Before connect-ing any HDMI products to your AVR, it is helpful to findout in advance their level of HDMI connectivity.Some source or display components in your systemmay use DVI (Digital Video Interface) for digital videoconnections. DVI carries the same digital video signalsas HDMI but uses a larger connector and does nottransport audio or control signals. In most cases, youmay mix and match DVI and HDMI digital video con-nections by using optional connector adapters. Note,however, that some DVI-equipped video displays arenot compatible with the HDCP copy protection codingthat is increasingly carried with signals connected via HDMI. If you have an HDMI source and a DVI-equipped display, you may occasionally be unable toview a program if the display does not include HDCP.This is not the fault of the AVR or your source; it sim-ply indicates that the video display is not compatible.HDMI Input ConnectionsThe different “Version” levels of HDMI define whichtype of audio signals it is compatible with. Based onthe lowest level of HDMI among your sources, theconnections to the AVR should be made as follows:• HDMI 1.0 sources carry digital video and multi-channel or 2-channel PCM audio signals only.Connect the HDMI output of a 1.0 source to eitherof the HDMI Inputs Non the AVR. If the productis a DVD-Audio player or other source that has mul-tichannel analog audio outputs, connect them to the8-Channel Direct Inputs f.With an HDMI 1.0source, particularly a DVD player, make certain that the menus in the source device are set to“Bitstream Out” or “Original” so that 5.1 digital audiois available. If you find that 5.1 Dolby Digital or DTSaudio is not available on the HDMI connection, it will be necessary to make an additional connectionbetween the source and the AVR 745 to either theCoaxial dMor Optical eKDigital Inputs.• HDMI 1.1 sources carry the multichannel digitalaudio output from DVD-Audio players in addition tothe digital video. If you have an HDMI 1.1-equippedproduct, the only connection needed for listening in the main room is from the HDMI output of thesource to either of the HDMI Inputs Non theAVR. If the player has SACD capability, you will needto connect the analog outputs of the source to the8-Channel Direct Inputs f.• HDMI 1.2(and higher) sources should be connectedas shown above for HDMI 1.1, except that a separate analog connection is not needed for SACD players.• It is not possible to feed an analog composite or S-video signal to a recorder or the AVR’s multizonesystem when an HDMI input is in use. If an HDMI-equipped source also has analog audio and videooutputs, connect them to the Video 2 or Video 3Video VW and Audio hi on the AVR.• In some instances, HDMI-equipped sources will notpermit more than one video output at a time, andthus you cannot use the same source in the mainlistening room and with the recorder or remote zoneat the same time. This is not a fault of the AVR, butrather a function of the content protection systemsthat are part of the HDMI standard.HDMI Output ConnectionsConnect the HDMI Output Mto an HDMI input onyour video display. Thanks to the AVR 745’s videoprocessing system, all video input signals are convertedto an HDMI output, so only one connection is requiredbetween the AVR and your display.System and Power ConnectionsThe AVR 745 is designed for flexible use with multi-room systems,external control components andpower amplifiers.Main Room Remote Control ExtensionIf the receiver is placed behind a solid or smoked-glass cabinet door, the obstruction may prevent theremote sensor from receiving commands. In thisevent, an optional remote sensor may be used.Connect the output of the remote sensor to the IR Input fl.If other components are also prevented from receivingremote commands, only one sensor is needed. Simplyuse this unit’s sensor or a remote eye by running aconnection from the IR Output ‹to the Remote IRInput jack on Harman Kardon or other compatibleequipment.If other Harman Kardon-compatible source equipmentis part of the main room installation, the IR OutputJack ‹on the rear panel should be connectedto theIR IN jack on source equipment.

INSTALLATION AND CONNECTIONSremote room location to control source equipmentfunctions.When a remote IR sensor is used to control non-Harman Kardon source equipment, we recommendthat you make a hard wire connection or use anoptional, external IR “blaster” connected to the FullCarrier IR Output ¤. If you are in doubt as to whichIR Output jack to use for the equipment in your sys-tem, contact your dealer or installer, or the manufac-turer’s support site and ask whether the unit to becontrolled uses “full carrier” IR commands. When “fullcarrier” commands are used, make the connection tothe Full Carrier IR Output ¤. Otherwise, make theconnection to the IR Output ‹.NOTE: All remotely controlled components must belinked together in a “daisy chain.” Connect the IR OUTjack of one unit to the IR IN of the next to establishthis chain.Multiroom Audio ConnectionsThe AVR 745 is equipped with multizone capabilitiesthat allow it to send a separate audio and videosource to the remote zone from the one selected foruse in the main room.Depending on your system’s requirements, threeoptions are available for audio connection:Option 1: Use high-quality, shielded audio intercon-nect cable from the AVR 745’s location to the remoteroom. In the remote room, connect the interconnectcable to a stereo power amplifier. The amplifier will beconnected to the room’s speakers. At the AVR 745,plug the audio interconnect cables into the MultiroomAudio Outputs Uon the AVR 745’s rear panel.Option 2: Connect the Multiroom Audio OutputsUon the AVR 745 to the inputs of an optional stereopower amplifier. Run high-quality speaker wire fromthe amplifier to the speakers in the remote room.Option 3: Taking advantage of the AVR 745’s built-inseven-channel amplifier, it is possible to use two of theamplifier channels to power speakers in the remoteroom. When using this option, you will not be able touse the full 7.1-channel capabilities of the AVR 745 inthe main listening room, but you will be able to addanother listening room without external power ampli-fiers. To use the internal amplifiers to power a remotezone, connect the speakers for the remote room loca-tion to the Surround Back/Multiroom SpeakerOutputs fi. Before using the remote room, you willneed to configure the amplifiers for surround operationby changing a setting in the MULTIROOMmenu, following the instructions shown on page 51.NOTE: For all options, you may connect an optional IR sensor in the remote room to the AVR 745 via anappropriate cable. Connect the sensor’s cable to theMultiroom IR Input gon the AVR 745 and use the ZR 10 remote to control the room volume. You mayinstall an optional volume control between the output ofthe amplifiers and the speakers in options 1 and 2.Multiroom Video ConnectionsThe AVR 745’s multiroom system is designed to sendboth video and audio signals to a remote room loca-tion. This may be the same source that is in use in themain room, or you may select a separate input sourcethrough the Multiroom menu or remote, as explainedon page 52.The only additional connection required to add videocapabilities to your multiroom system is to connect theMultiroom Video Output Leither directly to thevideo display in the remote room or to any optionalvideo distribution amplifiers that may be required whenthe length of the connection cable is such that addi-tional amplification is required.The following items may be of additional assistancewhen using video as part of a multiroom system withthe AVR 745.• Component or HDMI video sources may not be routedthrough the multiroom system. When using acomponent video device, you should also make acomposite connection for the multiroom system.• As with all cable installations, when running anywiring inside a wall be certain that the cable carriesthe proper NEC rating for the application. The use ofimproperly rated cables may present a safety haz-ard. Consult a qualified installer or licensed electri-cian should you have any questions about the useof in-wall cables for video or audio.• When connecting the AVR 745 to the remote roomvideo display, be aware of the distance limitationsthat may exist for both composite and S-video con-nections.Although the use of low-loss coax forcomposite video and higher-grade S-video cablesmay reduce signal loss, optional distribution ampli-fiers may occasionally be required when long cableruns are used.A-BUS®Installation ConnectionsThe AVR 745 is among the few receivers availablethat offer built-in A-BUS/READY operation. When usedwith an optional A-BUS product, you have all the ben-efits of remote zone operation without the need for anexternal power amplifier.To use the AVR 745 with an approved A-BUS prod-uct, simply connect it to the AVR 745 using standardCategory 5 wiring that is properly rated for the specificin-wall installation. Terminate the wiring at the receiverend to a standard RJ-45 connector in compliancewith the instructions furnished with the A-BUS product.No further installation or adjustment is needed, as theA-BUS jack on the AVR 745 routes the signals to theirproper destination for power, signal source and control.The output fed to the A-BUS jack is determined by theAVR 745’s multiroom system and menus.RS-232 ConnectionsThe AVR 745 is equipped with an RS-232 SerialConnection Port bthat may be connected to acompatible, optional, external computer, keypad orcontrol system for bidirectional communications thatenable the external system to control the AVR, and forthe AVR to report status and handshake data back tothe controller. Use of the RS-232 port for this type ofcontrol requires specific technical knowledge, and werecommend that any connection and programming forcontrol be made by a trained installer or technicianfamiliar with the equipment being used.The physical connection to the AVR 745’s RS-232port is a standard D-SUB 9 connection, but to ensurecompatible and proper operation, specific softwarecommands and pin wiring schemes may be required.USB ConnectionsThe AVR 745 is one of the few A/V receivers to offera USB connection that may be used for both playbackof compatible audio content from a computer and forloading of system updates (when available).The physical connection between a computer and theAVR is a simple one, requiring only a cable with a USB“A” type connector on one side and a USB “Mini B” onthe other. If you do not need the USB cable providedwith the AVR 745 for programming the TC 30 remote,it may be used for this purpose.Connect the larger, “A” connector on the cable to yourcomputer or a USB hub and the end with the “Mini”USB connector to the USB Jack Zon the AVR’srear panel.NOTES ON USB:• The USB jack on the AVR 745 is for connection toa computer, or to a hub connected to a computer,only. DO NOT connect it directly to other devicessuch as card readers, USB memory storagedevices,external hard drives, USB accessories, digi-tal cameras or cellular phones. Connection to thesedevices may cause damage to the device and/orthe AVR that is not covered by the AVR’s warranty.• The AVR 745’s USB connection may only be usedfor audio playback and system upgrades. It may notbe used for other purposes, such as system control,video or still-image playback.Trigger ConnectionsThe AVR 745 is equipped with two low-voltage trig-gers that may be used to control a wide variety ofcompatible, optional devices that respond to voltageactuation commands. This includes external audiopower amplifiers, video screens, motorized blinds and other compatible products in a home theater orautomation system. Due to the complexity of inter-facing with power-controlled devices, we strong-ly recommend that they be installed by a quali-fied professional.INSTALLATION AND CONNECTIONS 17AVR 745 OM 5/15/06 5:00 PM Page 17

The con-nection is a 3.5mm mono mini plug with the signal onthe center pin (“tip”) and the outer shaft (“ring”) actingas the negative or ground connection.The Trigger 1 Output His for use with devicessuch as power amplifiers that you wish to activate withwhenever the AVR is turned on, regardless of the input selected.The Trigger 2 Output Iis for use with devicessuch as video screens or motorized blinds that youonly wish to activate when specific inputs, such asHDMI, DVD or one of the Video Inputs, are selected.When a device is connected to the Trigger 2 Output,the TRIGGER 2 setting on PAGE 2 of theINPUT/OUTPUT menus must be set to ON.See page 23 for more information.After checking for voltage, current and polarity com-patibility between the device being controlled and theAVR, simply connect one end of the trigger cable tothe device being controlled and the other end to thedesired Trigger Output on the AVR.IMPORTANT NOTE ON TRIGGER CONNECTIONS:The current draw from any one Trigger Jack cannotexceed 0.5mA. The combined total current draw forall devices connected when both jacks are in use maynot exceed 1.0mA.XM Radio ConnectionsXM Radio is a satellite-delivered, subscription-based,programming service that provides a wide range ofmusic, sports, news and information programming withdigital audio quality. The AVR 745 is XM Connect &Play-ready, which means that you can easily add theXM service to your home audio system by purchasingan XM antenna module or Passport system, activatingan account with XM and then making a simple,single-cable connection to your AVR.To purchase an XM antenna module or Passport system, consult your dealer, or contact XM Radio atwww.xmradio.com. After following the instructionspacked with the module, place the XM antenna near a south-facing window and run the cable to the AVR.Connect the plug at the end of the cable to the XMModule Input Y. If you are using an XM Passportsystem, remember that the Passport card must beinserted for the system to operate. Once the connec-tion is made, follow the instructions on page 46 formore information on listening to XM Radio.NOTES on XM Radio:• XM Radio requires the purchase of additional,optional hardware and a separate subscription to the XM service.• XM Radio is available only in the Continental UnitedStates and Canada. It is not available in Alaska or Hawaii.• XM reception requires that the antenna be able to“see” the XM satellites or receive a signal from oneof the XM ground-based repeaters. Depending onyour installation and location, XM service may notbe available in some areas.AC Power ConnectionsThis unit is equipped with an accessory AC outlet that may be used to power accessory devices, but itshould not be used with high-current draw equipmentsuch as power amplifiers. The total power draw toeach outlet may not exceed 100 watts.This Switched AC Accessory Outlet ‡is poweredonly when the unit is on. This is recommended onlyfor devices that have a mechanical power switch thatmay be left in the “ON” position.NOTE: Many audio and video products go into aStandby mode when they are used with switched out-lets. This type of product may not operate properlywhen used with the switched outlet.The AVR 745 features a removable power cord that allows wires to be run in advance to a complexinstallation so that the unit itself need not be installeduntil it is ready for connection. When all needed connections have been made, connect the AC power cord to the AC Power Cord Jack a.The AVR 745 draws significantly more current thanother household devices, such as computers, that useremovable power cords. For that reason, it is importantthat only the cord supplied with the unit (or a directreplacement of identical capacity) be used.Once the power cord is connected, you are almostready to enjoy the AVR 745’s incredible power and fidelity!AVR 745 OM 5/15/06 5:00 PM Page 18
SYSTEM CONFIGURATIONWhen all audio, video and system connections havebeen made, the final steps before listening to your newAVR are to make the configuration adjustments thattailor the unit to the other components in your systemas well as accommodate your personal listening pref-erences. A few minutes spent to correctly calibrate andconfigure your system will greatly add to your listeningpleasure.Speaker Selection and PlacementWhile the most seamless surround sound reproductioncomes from the use of speakers with identical or care-fully matched driver elements at each position, nomatter which brand or type of speakers you prefer, it is always best to use the same model or series for the left front, center and right front speakers. Similarly,it is also desirable to use the same model or series for the surround speakers. This ensures that the sound-stage will be relatively seamless when a sound movesfrom one side of the room to the other.Speaker PlacementOnce you have selected your speakers, it is importantthat they be placed in positions that enable them to dothe best job of reproducing the sound as it was meantto be heard, regardless of the program content. Theplacement of speakers can have a noticeable impacton the accuracy of the surround process, particularly inmultichannel systems.When placing your speakers in a listening room, pic-ture an imaginary circle starting at the center of yourvideo screen that arcs around the room with the primelistening position, or “sweet spot,” at the center of thecircle. Depending on the number of speakers in yoursystem, there is a recommended placement along thecircle for each speaker, though the specific construc-tion of your room, taking into account the availablewalls, bookcases, or floor space at which the speakersmay be placed will obviously have some impact onwhere the speakers are ultimately located. As a generalrule, try to place all speakers so that they are posi-tioned at the same height as your ears when you areseated at the prime listening position.Use the following suggestions as a guide, and makethe changes needed to fit the speakers to your room.Don’t be afraid to experiment a bit until you find theright combination of locations that works for you. Atthe end of the day, there is no real “right” or “wrong”place to put the speakers; work to optimize their loca-tions so that audio moves across the front of the roomsmoothly, without seeming to jump from one speakerto another.Front Left/Right SpeakersThe recommended placement for front left/rightspeakers is at the 30-degree position with referenceto the center channel speaker. The distance betweenthem should be about the same as the distance from thecenter channel speaker to the prime listening position.Although the natural tendency is to place the speakersso they are parallel to the wall behind them, and thusin line with the video screen, the preferred placementis to angle the speakers slightly (“toe in”) so that theypoint at the prime listening position.Center Channel SpeakerThe ideal location for the center channel speaker is at“0 degrees” in our circle, directly in front of the primelistening position. Place the center channel speaker asclose to the top (or bottom) of the video screen aspossible so that when you position the front left/rightspeakers the tweeters of all three front channel speak-ers are within 24" of one another.Surround Speakers for 5.1 SystemsIn a 5.1 surround system, an additional pair ofleft/right speakers is added. Although many believethat these speakers should be placed at the rear ofthe room, the preferred position for them is at thesides of the room, with rear placement a secondoption when room conditions prevent the use of side-mounted surround speakers.When side-wall placement is possible, place theleft/right surround speakers at a point that is 110degrees along our circle from the center of the videoscreen. This translates to placing them to the side andslightly behind your preferred listening position. If pos-sible, angle the speakers in slightly so that they arepointing toward the listener’s ears.5.1 Placement DiagramIf it is not possible to place the surround speakers atthe sides of the room, the alternate position is at theback of the room, at a spot that is about 150 degreesaround our circle from the center of the video screen.Another way to spot the optimal, alternate rear-wallmounting position is to place the left surround speakeron the back wall so that it points directly at the frontright speaker,and to have the right surround speakerpoint directly at the front left speaker. If possible,aim the surround speakers so that they point inward,toward the listening area, rather than perpendicular to the walls.Surround Speakers for 6.1 SystemsA 6.1 surround speaker adds an additional centerback surround speaker to the system, enabling you toenjoy the benefits of advanced surround modes suchas Dolby Digital EX, DTS-ES and Harman Kardon’sproprietary Logic 7/7.1 processing.To step up to a 6.1 system, first place the speakersfor a 5.1 system. The “sixth” speaker should ideally beplaced at the center of the room’s rear wall, pointingdirectly toward the front center channel speaker.6.1 Placement DiagramNOTE: The 6.1-channel configuration is not recom-mended for the AVR 745. We strongly recommend a7.1-channel installation as described below. When6.1-channel materials are played through a 7.1-chan-nel system, the same surround back channel informa-tion is played through both the left and right surroundback speakers.If you are only able to install a single surround backspeaker at this time,you will not be able to run the fullEzSet/EQII 7.2-channel calibration procedure. In thatcase, we suggest you install all of your speakersexcept the surround back speaker, and run theEzSet/EQII procedure for a 5.1-channel system (seepage 29). After EzSet/EQII has finished, connect thesingle surround back speaker to the left SurroundBack Speaker Outputs B. Then follow the instruc-tions starting on page 33 to manually configure yoursurround back speaker.We recommend that you consider adding a secondsurround back speaker as soon as possible.Center SpeakerVideo ScreenFront RightSpeakerFront Left SpeakerSide SurroundLeft SpeakerSide SurroundRight SpeakerBack SurroundSpeakerListening Position110 ° 110 °30° 30°Center SpeakerVideo ScreenFront Right SpeakerFront Left SpeakerSide SurroundLeft SpeakerAlternate placementfor Side SurroundLeft SpeakerSide SurroundRight SpeakerAlternate placementfor Side SurroundRight Speaker110 °150°110 °150°30° 30°SYSTEM CONFIGURATION 19AVR 745 OM 5/15/06 5:00 PM Page 19
SYSTEM CONFIGURATION20 SYSTEM CONFIGURATION20 SYSTEM CONFIGURATIONSurround Speakers for 7.1 or 7.2 SystemsFor the ultimate home theater experience, a 7.1 or7.2 surround system uses both traditional surroundleft/right channels and a surround back left/rightspeaker pair. In a 7.1 system, the front left/center/rightspeakers remain in the same place as they would befor a 5.1 or 6.1 system, but due to the number ofspeakers involved, the placement of the surroundspeakers is different.In a 7.1 system, you should place the main surroundleft/right speakers at the 90-degree point on our cir-cle. A good way to visualize proper surround speakerpositioning for 7.1 is to place the speakers directly tothe left and right of the ears of someone sitting in theprime listening spot. The two speakers should ideallyface toward each other.When two subwoofers are installed, the AVR 745 isable to create a smoother low-frequency reproductionwith more powerful bass.The additional Surround Back Left/Right speakers areplaced at about 150 degrees on the circle, pointinginward, toward the listening area. The easiest way tovisualize the placement of these speakers is to placethe surround back left speaker directly opposite theright front speaker and to place the surround back leftspeaker directly opposite the left front speaker.7.1 Placement DiagramSubwoofer PlacementSince subwoofers produce nondirectional sound, theymay be placed almost anywhere in a room. Actualplacement should be based on room size and shapeand the type of subwoofer used. One method of find-ing the optimal location for a subwoofer is to begin byplacing it in the front of the room, about six inchesfrom a wall, or near the front corner of the room.Another method is to temporarily place the subwooferat your normal listening position, and then walkaround the room until you find a spot where the sub-woofer sounds best. Place the subwoofer in that spot.You should also follow the instructions of the sub-woofer’s manufacturer, or you may wish to experimentwith the best location for a subwoofer in your listeningroom.The AVR 745 is equipped for 7.2 operation, whichmeans that you can increase the low-frequency per-formance of your system by using two subwoofers,rather than one. When using two subwoofers, the fol-lowing tips will add to the smoothness and power ofthe bass reproduction:• Although it is not mandatory, you will have the bestperformance when both subwoofers are identical interms of driver size, amplifier power and cabinetdesign (e.g., ported or sealed).• The optimal placement when two subwoofers are inuse is to have them on the side walls of the room,to the immediate left and right of the listening posi-tion. If that positioning is not practical, a good alter-native is to place the subwoofers in the front left and right corners of the room, or to place the subwoofers in any two corners of the room.• Regardless of which subwoofer placement option ischosen, EzSet/EQII will help to smooth room condi-tions to deliver the optimal bass response.For more information on subwoofer placement, as wellas a variety of topics relating to audio and home the-ater, visit the Technology section of our Web site atwww.harmankardon.com. Links are provided there toinformative white papers written by the acoustic andelectronics experts at Harman Kardon and at our par-ent company, Harman International Industries, Inc.NOTES ON SPEAKER PLACEMENT:1. The limitations of your listening room, including theplacement of walls and furniture, may make it diffi-cult to follow the speaker placement suggestionsshown above. Depending on the specific layout ofthe room, here are some ways to compensate forunusual conditions:• Try to follow the suggested placement, but movethe speakers within a few feet from the preferredlocations.• Regardless of where they are placed, always tryto make certain that the main surround speakersare the same distance from the front speakers.(For example, try not to have the right surroundspeaker further back into the room than the leftsurround speaker.)• If it is not possible to wall-mount or place speak-ers on a shelf, consider the use of optional floorstands, available for many speakers.2. When using ceiling-mounted in-wall speakers, fol-low the same guidelines shown for conventionalfloorstanding or shelf-mounted speakers.3. When you have reassigned the surround backchannels for use in a multiroom system, follow thespeaker placement instructions for a 5.1-channelsystem for your main listening area (see page 19).Remote Control SetupThe AVR 745 comes with two remotes, Harman Kardon’sTC 30 activity-based remote control with color LCDand the ZR 10, which is designed primarily for use inremote rooms but which may also be used as a com-pact remote in your main home theater room.The TC 30 remote packed with your new receiver willoperate the AVR 745 without any further program-ming. However, in order to take full advantage of theTC 30’s power and flexibility, you will need to programit via the Internet so that the codes needed to controlthe other devices in your system (such as a video dis-play, DVD players and set-top boxes) are transferredinto the TC 30’s memory. Programming the TC 30is easy, and complete instructions for setting up theTC 30 may be found in the separate InstallationGuide for the remote.Before using the TC 30, you must install the recharge-able battery and connect the charging cradle to itspower supply. The battery should then be charged forat least twelve hours before using the TC 30.To allow you to continue with the setup of yourAVR 745 while the TC 30 battery is charging, theZR 10 may be used to navigate through the systemmenus. No configuration is required; simply removethe battery compartment door on the back of the ZR 10and install the AAA batteries supplied with the AVR.Replace the battery cover and you are ready to go! System SetupOnce the speakers have been placed in the room andconnected, the remaining steps in the setup processare to assign input and output connections, make anyvideo or audio adjustments, select a surround mode,program the AVR 745’s bass management system forthe type of speakers used in your system, calibratethe output levels and set the delay times used by thesurround sound processor.Although it is necessary to assign input/output settingsand surround mode choices manually,we recommendthat you take advantage of the power and precision ofEzSet/EQII to automatically select and enter the set-tings for all other audio parameters. This will not onlysave you time; it will ensure that your room is calibratedand equalized with an accuracy not possible whenthese settings are made manually.You are now ready to power up the AVR 745 to beginthese final adjustments.1.

Press the Main Power Switch Alocatedbehind the Front-Panel Control Door 9inuntil it latches and the word “OFF” on the top ofthe switch disappears inside the front panel. Notethat the illumination around the Standby/OnSwitch 1will turn amber, indicating that theunit is in the Standby mode.3. Carefully remove the protective plastic film fromthe front-panel lens. If left in place, the film willprevent proper operation of the remote control.4. Turn the AVR 745 on either by pressing theStandby/On Switch 0on the front panel, bypressing the AVR Selectorçor any buttonon the ZR 10 remote that selects an input source(Input Source Buttons∂,Tuner SelectorÉ,XM Radio Selectorƒor The Bridge/DMP Selector®), or by pressing theDevices Button 4on the TC 30 and thenpressing the Screen Button 6at the top ofthe left side of the remote, next to the screenmessage AV Receiver.The lightingaround the Standby/On Switch 0and theVolume Control 9will turn blue and the frontpanel display will light to confirm that the unit is on.Using the On-Screen DisplayWhen making the following adjustments, you may findit easier to use the AVR 745’s on-screen display sys-tem. These easy-to-read displays give you a clear pic-ture of the current status of the unit and make it easyto see which speaker,delay, input or digital selectionyou are making.To view the on-screen menus, make certain you havemade a video or HDMI connection on the rear panelto the appropriate matching input of your TV or pro-jector. In order to view the AVR 745’s displays, thecorrect video source must be selected on the video display.IMPORTANT NOTE: When viewing the on-screenmenus using a CRT-based projector, plasma display or direct-view CRT monitor or television, it is importantthat they not be left on for an extended period of time.Prolonged display of a static image such as these menusmay cause the image to be permanently “burned into”the projection tubes,plasma screen or CRT display.Thistype of damage is not covered by the AVR 745 warrantyand may not be covered by the video display’s warranty.The AVR 745 has two on-screen display modes.“Full-OSD” displays comprehensive menus of systemoptions that may be adjusted using the navigation but-tons on the remote. The “semi-OSD” system displaystwo-line messages at the bottom of the screen and istypically used to make minor adjustments to previouslyestablished settings with discrete function controls onthe remote. We strongly recommend that the full-OSDsystem be used for the AVR 745’s initial setup andconfiguration, as it contains many system options notaccessible through the discrete function buttons andsemi-OSD messages.Making Configuration AdjustmentsTo activate and configure the AVR 745 using the full-OSD system, either the TC 30 remote or the ZR 10remote may be used, though you may find the ZR 10 an easier choice for this purpose.With the TC 30:• Press the Devices Button 3.• When the images on the LCD screen change, pressthe Screen Button 6at the top of the left sideof the remote, next to the screen message AVReceiver.• Press the Menu Button Ato activate the OSDmenu system.• When the Master Menu or any subsequentmenu is on the screen, use the ⁄/¤NavigationButtons Dto move through the menus or sub-menus.

This flexibility enables you to customize theway in which you listen to each source and have theAVR 745 memorize those settings. Once these set-tings are made, they will automatically be recalledwhenever you select that input.To simplify initial configuration and operation, theAVR 745 has been preconfigured with input settingsthat are typical for home theater systems. These set-tings are detailed in the worksheets in the Appendix.Before adjusting the input settings, it is a good idea tocompare your input connections to the defaults so thatyou may see where changes need to be made.Before using the unit, you may want to change thesettings for some inputs so that they are properly configured to reflect the use of digital or analog inputs, the type of video display and speakersinstalled, and the surround mode specifics of yourhome theater system.In/Out SetupThe first step is to configure each input source. Whenan input is selected,the settings will “attach” them-selves to that input and be stored in a nonvolatilememory. Once made, the selection of an input willautomatically recall those settings. For that reason, theprocedures described below must be repeated foreach input source so that you have the opportunity to customize each source to your specific listeningrequirements. However, once done, they need not be changed again unless your system componentshave changed.When using the full-OSD system to make the setupadjustments, press the Menu Button Aor OSDButton∫once so that the MASTER MENU(Figure 1) appears. The cursor will be next to theIN/OUT SETUP line. Press the On/EnterButton Eor the Set Buttonœand the firstpage of the IN/OUT SETUP menu (Figure 2)will appear on the screen. Press the ‹/›NavigationButton D©until the desired input name appearsin the highlighted video, as well as being indicated inthe front-panel Input Indicators !.Figure 2When one of the four Video inputs is selected as thesource, you have the option of renaming the input as itappears in the on-screen and front-panel messages.This is helpful if you have more than one VCR, if youwish to associate a specific product brand name withthe input, or to simply enter any name that will helpyou to remember which source is being selected.To change the input name, press the ⁄/¤Navigation Buttons D©on the remote so thatthe cursor is pointing to TITLE. Next, press andhold the Set Buttonœfor a few seconds until a flashing box appears to the right of the colon.Immediately release the On/Enter Button Eor the Set Buttonœ, as you are now ready to enterthe device name.Press the ⁄/¤Navigation Buttons D©andnote that alphanumeric characters will appear with the start of the alphabet in capital letters, followed bythe lowercase letters, and then numbers and symbols.When you press the ¤Navigation Button D©, the symbols and numbers will appear first, fol-lowed by a reverse list of the alphabet in lowercaseletters. Press the button either way until the first letterof the desired name appears. If you wish to enter ablank space as the first character, press the ›Navigation Button D©.When the desired character appears, press the ›Navigation Button D©and repeat the processfor the next letter, and continue until the desired nameis entered, up to a maximum of 14 characters. Press the On/Enter Button Eor the Set Buttonœtoenter the input name into the system memory and toproceed with the configuration process.After entering the input title, press the ⁄/¤Navigation Buttons D©to move to the next line.The audio input defaults for all sources except theTuner, USB and 6/8-Channel Direct inputs are shownin the table in the Appendix. If your system configura-tion follows the default table, no changes are neededand you may press the ⁄/¤Navigation ButtonsD©to move to the next line.With the cursor pointing to AUDIO IN-PORT,press the ‹/›Navigation Buttons D©tochange the default to a different audio input connec-tion. When the name of the desired input appears,press the ⁄/¤Navigation Buttons D©tomove to the next line.Note that in addition to using the menu system tochange the audio input, you may change it at any timewith the TC 30 remote by following these steps:• Press the Devices Button 3.• When the images in the LCD change, press theScreen Button 6at the top of the left side of the remote, next to the screen message AVReceiver.• At the next screen, press the Screen Button 6to the left of the message Setup Menu.• When the new list of options appears, press theScreen Button 6to the right of Digital Input.The current digital input name will begin to flash inthe Upper Display Line C.• Press the ‹/›Navigation Buttons Duntil thedesired input name appears on the right side of the Upper Display Line Cor in the semi-OSDmessage.• After five seconds, the input name will stop flashing,as it is entered into the system memory and the unitwill return to normal operation.In normal operation, when a digital audio stream isinterrupted, the unit will automatically switch to theanalog inputs associated with that source. This is par-ticularly useful with cable set-top boxes where theinput is normally digital, but occasionally changes toanalog. If you wish to configure an input so that theauto-poll circuit is turned off, while the on-screen cur-sor is pointing to the AUDIO AUTO POLLline, simply press the ‹/›Navigation ButtonsD©so that OFF (rather than ON) is in a whitevideo highlight.When the desired auto-poll setting is entered, pressthe ⁄/¤Navigation Button D©to move tothe next line.When the cursor is at the VIDEO IN-PORTline, you are able to select an alternative to the defaultinput setting for the video input associated with anysource. For the Video 1 and Video 4 inputs, the factorydefault of AUTO will select either composite or S-video, depending on which has an active signal. Forthe Video 2, Video 3 and DVD inputs, the AUTOsetting will normally select the default componentinput, but if it is not in use, the system will revert to acomposite or S-video output if either one is active.To have the AVR always look to a specific source con-nection when an input is selected, make certain thatthe on-screen cursor is pointing to the VIDEOIN-PORT line, and then press the ‹/›Navigation Buttons D©until the name of thedesired input appears. The default setting for HDMIinputs is AUTO and normally need not be changed.However, in systems where the HDMI connection isused for multichannel audio only (e.g., HDMI 1.1), butthe video connection is component, due to limitationson the video display, the setting here should bechanged to COMPONENT.When the desired video input setting has been made,press the ⁄/¤Navigation Buttons D©tomove to the next line.If your system includes any sources that are equippedwith Y/Pr/Pb component video outputs, the AVR 745is able to switch them to send the proper signals toyour video display. Each of the Component VideoInputs Qis assigned to a default source,as shownin the table in the Appendix, but if you have connected * IN/OUT SETUP * SOURCE: VIDEO 1TITLE: AUDIO IN-PORT: ANALOGAUDIO AUTO POLL: ON OFFVIDEO IN-PORT: AUTOCOMPONENT INPUT: COMP 1VIDEO PROCESS: FAROUDJAA/V SYNC DLAY: 0mSMASTER MENU PAGE 2→ SYSTEM CONFIGURATIONAVR 745 OM 5/15/06 5:00 PM Page 22
SYSTEM CONFIGURATIONyour system differently than the factory settings, youmay select any of the three inputs for any sourceexcept the HDMI inputs or the Tuner. If you do notneed to change these defaults, press the ¤Navigation Button oto go to the next setting.To change the Component Video assignment, firstmake certain that the cursor is pointing to theCOMPONENT INPUT line on the menuscreen, and then press the ‹/›Navigation ButtonD©until you see the desired input in the high-lighted video.When the desired component input has been selected,press the ¤Navigation Button D©to go tothe next setting.At the VIDEO PROCESS line, you are able toselect which type of video processing or conversion, ifany, is to be used with the input source being config-ured. The default setting is to have the AVR 745’sFaroudja processing circuitry in use, which will deliverthe best image quality when a digital video display is inuse. If you do not need to change the setting, simplypress the ⁄/¤Navigation Buttons D©tomove to the next line.If your video display is not capable of accepting high-resolution (480p and above) signals through either an HDMI or component video connection, it is veryimportant that this setting be changed. Three optionsare available:The default setting is FAROUDJA.Depending onthe input source, the video signals will be handled indifferent ways:• A standard-definition (480i) analog signal (compos-ite, S-video or component) will be digitized and sentto the Faroudja video processor for enhancement.The signal will be available as both an analog component and HDMI signal. The standard definition video signal will also be available at therecord outputs.• An analog component high-definition signal will bedigitized and sent to the Faroudja video processorfor enhancement. The signal will be available asboth an analog component and an HDMI signal, butnot at the analog composite or S-video monitor orrecord outputs.• Any HDMI signal other than 1080i will be sent tothe Faroudja video processor for enhancement andit will be available as an output at both the HDMIand analog component outputs. Program materialthat carries HDCP copy protection encoding will onlybe available through the HDMI output.• HDMI signals in 1080i resolution will be sent directlyto the HDMI and analog component outputs withoutprocessing. Program material that carries HDCPcopy protection encoding will only be availablethrough the HDMI output.The V-CONVERSION setting will not applyany video enhancement or processing to the incomingvideo signal, but it will output it in one of the followingways, depending on the input source.• A standard-definition (480i) analog signal (compos-ite, S-video or component) will be converted so thatit is available as an HDMI signal at its input resolu-tion, as well as at the standard composite, S-videoor component analog video outputs. The signal willalso be available at the record outputs.• An analog component high-definition signal will bedigitized and output at its input resolution throughthe HDMI outputs and as an analog component signal, but not through the analog composite or S-video monitor or record outputs.• HDMI input signals, regardless of their resolution, willbe output through both the HDMI and analog com-ponent outputs. Program material that carries HDCPcopy protection encoding will only be availablethrough the HDMI output.The BYPASS setting will not apply any videoenhancement or processing to the incoming video sig-nal, but it will output it in one of the following ways,depending on the input source.• Analog signals (composite, S-video or component)will output only in the resolution and format thatmatches the input for both the main “Monitor” con-nection as well as for the record outputs.• HDMI input signals, regardless of their resolution, willbe output through the HDMI and analog componentoutputs. Program material that carries HDCP copyprotection encoding will only be available throughthe HDMI output.In addition to the changes to the video processingconfiguration that are made through the IN/OUTSETUP menu, you may change the setting for aninput at any time by pressing the ‹/›Buttons Hon the front panel to cycle through the available choices.When any needed change to the video processingsetting has been made, press the ⁄/¤NavigationButtons D©to move to the next line.At the A/V SYNC DELAY line, you are able toenter a setting that delays the audio output slightlybehind the video so that the loss of lip sync that mayoccur due to digital video processing in the transmis-sion of a program, in the playback unit or in the dis-play is corrected. This lack of lip sync is not a fault ofthe sources; rather, it is a by-product of video signalprocessing. In most cases, we recommend that thedelay adjustment be made using the direct-accesscontrols on the remote so that you may more accu-rately adjust the delay while viewing the on-screenimage, following the instructions shown on page 36,but you may also make it here using the menu sys-tem. As the amount of delay needed may vary fromone source to another, we strongly recommend thatyou adjust it for each input.To adjust the A/V sync delay time from theIN/OUT SETUP menu, make certain that thecursor is pointing to the A/V SYNC DELAYline, and then press the ‹/›Navigation ButtonsD©until the desired amount of delay is appliedso that the on-screen video matches the audio.When all configuration adjustments on this menuscreen have been made, press the ⁄/¤NavigationButtons D©until the on-screen cursor is point-ing to PAGE 2and then press the OK/EnterButton Eon the TC 30 or the Set Buttonœon the ZR 10 remote to move to the second screenof input/output settings. If all settings for input configu-ration are complete, press the ⁄/¤NavigationButtons D©until the on-screen cursor is point-ing to MASTER MENU and then press the SetButtonœon the ZR 10 remote to return to themain menu screen.The second page of the IN/OUT SETUPmenu (Figure 3) allows you to further configure theAVR 745 for special custom features.Figure 3The TRIGGER 2 line enables you to choosewhether a trigger voltage signal is sent to the Trigger2 Output Jack Iwhen a specific input is selected.Unlike the Trigger 1 Output H, which always has atrigger voltage present when the AVR 745 is turnedon, the default for the Trigger 2 connection is off. Thesetting on this menu line allows you to turn it on for aspecific input so that an input or source-dependentaccessory (such as a motorized projection screen orblinds) may only be activated when, for example, aninput which requires a projection screen or darkenedroom is selected.To change the setting, press the ‹/›NavigationButtons D©until the desired setting appears.Press the ⁄/¤Navigation Buttons D©tomove to the next line when the setting is correct or ifno configuration changes are required.The front-panel analog Video 4 Jacks Nare nor-mally set as inputs for use with camcorders, videogames and other portable audio/video products,butthey may be switched to outputs. First, make certainthat you are at the IN/OUT SETUP menu. * IN/OUT SETUP * TRIGGER 2 :OFF ONVIDEO 4 :IN OUTCOAXIAL 4 :IN OUTREC OUT :ANALOGMASTER MENU PAGE 1➔ SYSTEM CONFIGURATION 23SYSTEM CONFIGURATION 23AVR 745 OM 5/15/06 5:00 PM Page 23

The Input/Output StatusIndicator Lbetween the S- and composite videojacks will turn red, indicating that the analog Video 4jacks are now record outputs.Selection of the front-panel jacks as outputs willremain effective as long as the AVR 745 is on. Oncethe unit is turned off, the jacks will revert to their nor-mal use as inputs when the unit is turned on again.An exclusive Harman Kardon feature is the ability toswitch the front-panel coaxial digital audio and analogaudio/video jacks from their normal use as inputs tooutput connections so that portable recording devicesmay easily be connected. On the AVR 745, theCoaxial 4 Digital Jack Mis normally an input, but itmay be switched to a digital output for use with digitalrecorders. To change the jack to an output, press the⁄/¤Navigation Buttons D©while theIN/OUT SETUP menu is on screen until thecursor is next to COAXIAL 4.Then press the‹/›Navigation Buttons D©so that OUT ishighlighted. The Input/Output Status Indicator Lwill then turn red, indicating that the jack is now arecord output.NOTE: A signal will be sent to this jack only when theinput selected for use by the AVR 745 is digital. Digitalsignals will be passed through, regardless of their for-mat, and which digital input (optical or coax) they arefed from. Analog signals are not converted to digital,and their format (e.g., PCM, Dolby Digital or DTS) maynot be changed.The REC OUT line enables you to select what the audio output is at the analog record outputs forthe input source being configured. Press the ‹/›Navigation Buttons D©to choose one of thefollowing if you wish to change the default setting:•ANALOG selects an unprocessed pass-throughof an analog source and is the default setting formost inputs.• DSP DOWNMIX selects a two-channel down-mix of a multichannel digital input.When the adjustment has been made, or if no adjust-ment is required and all settings on this page arecomplete, press the ⁄/¤Navigation ButtonsD©until the on-screen cursor is pointing toPAGE 1 and then press the OK/Enter ButtonEon the TC 30 or the Set Buttonœon the ZR 10 remote to return to the main IN/OUTSETUP menu to configure another input, or if nofurther input configuration adjustments are needed,press the ⁄/¤Navigation Buttons D©until the on-screen cursor is pointing to MASTERMENU and then press the OK/Enter Button Eon the TC 30 or the Set Buttonœon the ZR 10remote to return to the main menu screen.Video Monitor SettingsThe VIDEO MONITOR SETTINGSmenu (Figure 4) is unique in that it contains a mix ofinformation display lines that detail status informationabout the AVR 745’s video system settings, along with a few lines where a specific parameter may bechanged. With the MASTER MENU on thescreen, press the ⁄/¤Navigation Buttons D©until the on-screen cursor is pointing toVIDEO MONITOR SETTINGS and then press the OK/Enter Button Eon the TC 30or the Set Buttonœon the ZR 10 remote tomove to the menu screen.Figure 4The IN VIDEO FORMAT line is an informa-tional display of the resolution of the incoming videostream, and may not be adjusted.The IN VIDEO COPY PROT line is aninformational display that shows whether or not anincoming video signal contains copy protection encoding, and may not be adjusted.The VIDEO PROCESS line is an informational display of the setting made in theIN/OUT SETUP menu indicating how incoming video is processed for the input beingviewed, and may not be adjusted.The OUT VIDEO FORMAT line is a non-adjustable informational display of the video resolutionof the output signal, as determined by the input andwhether or not video processing or conversion is in use.The COMPONENT OUT line is an informationaldisplay of whether or not the Composite Video outputsare ENABLED or OFF,based on the input sig-nal type and resolution, and whether or not the incom-ing video signal has HDCP content protection. It maynot be adjusted.The S-VIDEO OUT line is an informational dis-play of whether or not the S-video outputs are avail-able at a 480i resolution (or OFF), based on theinput signal type and resolution and whether or not theincoming video signal has HDCP content protection.It may not be adjusted.The DISPLAY INTER line allows you tochoose between an ANALOG video output defaultvalue and an HDMI/DVI output by pressing the‹/›Navigation Buttons D©to make thedesired selection. When the setting is ANALOG,the HDMI output is placed in a Standby mode so thatit automatically switches to HDMI when an HDMI signalis detected. If a high-definition input source is notHDCP-content-protected, it may be output through thecomponent jacks; otherwise, it will be sent only to theHDMI outputs. The HDMI/DVI setting routes allconverted or processed video to the HDMI outputs.The HDMI AUDIO OUT line allows you tochoose whether a two-channel downmix of the audiothat accompanies the selected source is sent over the HDMI connection (YES) at the maximum bit ratethe display’s audio system is capable of handling, ornot (NO). To change the setting, press the ‹/›Navigation Buttons D©to make the desiredselection.When required adjustments have been made for thisinput, or if no adjustment is required, press the ⁄/¤Navigation Buttons D©until the on-screencursor is pointing to BACK TO MASTERMENU and then press the OK/Enter Button Eon the TC 30 or the Set Buttonœon the ZR 10remote to return to the main menu screen.Video SetupThe AVR 745 is among the very few audio/videoreceivers that include an onboard video processingsystem using DCDi by Faroudja technology. It is uniquein that it also allows the video controls to be individuallyset for each video input source. This permits you tocompensate for the problems inherent in older tech-nologies such as VCR while taking the maximumadvantage of new source options such as DVD,digital cable and satellite programming.IMPORTANT NOTE: The video processing is onlyavailable when the AVR 745 is connected to a “digital-ready” or HDTV video display that is able to accom-modate input sources of 480p or greater via an ana-log component or HDMI connection. If your video dis-play does not have that capability,you may skip thesettings in this section, as they will not apply to yourhome theater system.Within the VIDEO MAIN menu are the settingsthat define the input and establish the global settingsfor the video output. The two video ADVANCEDCONFIGURATION submenus contain theindividual parameters that will be applied to the specificvideo input in use. Before proceeding with the setup,we suggest that you look at the default settings foreach input, which are listed in the appendix to thismanual. If the settings for any input mirror the configu-ration of your home theater system, then no furtheradjustment is needed.It is worth noting that the impact of many of the indi-vidual settings is subtle, and it is only when they aregrouped together that the full power of the video pro-cessing system is unleashed.

Feel free to experiment with differentsetting combinations, as you can't “hurt” anything bydoing so.When you do reach the combination of settings forboth your display system and each input, it is a goodidea to write those settings down using the worksheetsfound on pages 55 – 57. (A copy of the blank work-sheets may also be found in the support section ourWeb site at www.harmankardon.com/support.) To reach the VIDEO MAIN menu, first makesure the MASTER MENU is on the screen, andthen press the ‹/›Navigation Buttons D©until the on-screen cursor is pointing to VIDEOSETUP and then press the OK/Enter Button Eon the TC 30 or the Set Buttonœon the ZR 10remote.

At the same time,any video input namepreviously changed to individualize the source settingwill be shown on the TITLE line. To change thetitle, go back to the IN/OUT SETUP menu.Once the source to be adjusted has been selected,press the ⁄/¤Navigation Buttons D©untilthe on-screen cursor is pointing to SOURCETYPE as the two lines below the TITLE lineare informational only,and their setting may not beadjusted in this menu.• The VIDEO IN-PORT line shows the videoinput jacks used for this input. If AUTO has beenselected, the display will alternate between AUTOand the actual active input.• The VIDEO PROCESS line shows whetherthe system is in the Bypass, Video Conversion orFaroudja video processing mode. Note that theFAROUDJA setting must be enabled for the inputbeing adjusted through the IN/OUT MENUin order for the settings available on this menu andthe ADVANCED CONFIGURATIONmenus to be active.Once an input is selected, the first configuration choiceis to tell the AVR 745 what type of device is beingused for that source. To change this setting from thesystem default, press the ¤Navigation ButtonD©so that the on-screen cursor is pointing to SOURCE TYPE and then press the ‹/›Navigation Buttons D©to select, from amongthe options shown, one that is closest to the type ofproduct connected to that input. The selection madewill change the settings on the ADVANCEDCONFIGURATION SUB-MENUS tothose best suited to that type of device. Of course, youmay also change these settings yourself at any timethrough the submenus.The list of input source defaults is:DVD: This setting is optimized for use with theoutput signal of a typical DVD player.VCR: This setting is optimized for use with theoutput signal of an analog videocassette recorder.CABLE DIG: This setting is optimized foruse with digital cable set-top boxes. However, it isimportant to note that even when a digital cablesystem is in use, there may be a mix of digital andanalog channels. We recommend that you start withthis setting and then change the options in theADVANCED CONFIGURATIONmenus as needed, to tailor the output to your preferences.SAT DIG: This setting is optimized for usewith digital satellite-system set-top boxes.CABLE ANA: This setting is optimized foruse with analog cable set-top boxes.SAT ANA: This setting is optimized for usewith analog satellite-system set-top boxes.CAMERA ANA: This setting is optimized foruse with analog VCRs and camcorders.CAMERA DIG: This setting is optimized foruse with digital camcorders or still-image cameras.The DISPLAY TYPE line is a global, ratherthan input-dependent setting, as there is only one dis-play connected to the AVR. The settings here are pri-marily changes to the video enhancement level andaspect ratio for a specific type of device, and defaultswere selected after testing on a wide range of brands. To change this setting, press the ¤Navigation Button D©so that the on-screen cursor is pointing to DISPLAY TYPEand then press the ‹/›Navigation Buttons D©to select, from among the options shown, onethat is closest to the type of display being used. Theselection will change the settings on theADVANCED CONFIGURATIONSUB-MENUS to the parameters best suited tothat type of display. Of course, you may also changethese settings yourself at any time, through the sub-menus. The list of input source defaults is:CRT: This setting is optimized for use with dis-plays that use cathode ray tubes (CRTs) to displayimages. For the purposes of this setting, it does notmatter whether the display is a single tube, direct-view CRT TV or a three-tube front or rear projector.The default aspect ratio is 4:3, but you may changethat setting, if desired, on the second page of theAdvanced Configurationsubmenus, as shown on page 27.REAR PROJECT: This setting is optimizedfor rear projectors,regardless of the imaging tech-nology used.FRONT PROJECT: This setting is opti-mized for front projectors, regardless of the imagingtechnology used.PLASMA: This setting is optimized for plasmadisplays, regardless of whether they are true high-definition or “ED” displays that are HD-compatible.DLP: This setting is optimized for use with pro-jectors that use light engines with Texas Instruments’DLP®technology. For the purposes of this setting,it does not matter whether the display uses one orthree chips, or whether the display is front or rearprojection.LCD: This setting is optimized for use with dis-plays that use liquid crystal display (LCD) technology.For the purposes of this setting, it does not matterwhether the display is a direct-view LCD flat panel,or front or rear projector.The ENHANCE LEVEL setting adjusts thedegree to which the enhancement circuits that adjustthe high-frequency content of the signal are applied.This is similar to the "Sharpness" control on a tradi-tional television. This setting acts on the vertical andhorizontal as well as the luminance and chrominancesignals to offer what will appear as enhanced depth inthe picture as well as greater small object detail. Ingeneral, lower settings are applicable for digital dis-plays and sources, while higher settings may be pre-ferred for CRT-based displays and digital sources.If you wish to change the default setting to suit yourspecific display type, input sources and personalimage preferences, when the VIDEO MAINmenu is on the screen, press the ¤NavigationButton D©so that the on-screen cursor ispointing to ENHANCE LEVEL and then pressthe ‹/›Navigation Buttons D©to enter thesetting that delivers the best image to your eyes onthe scale of 0 to 100.After any changes to the ENHANCE LEVELline have been made,press the ⁄/¤NavigationButtons D©so that the on-screen cursor ispointing to the PICT ADJUST line.

SYSTEM CONFIGURATIONTriangle Fixed: This test signalputs two opposing triangles on screen, with a blacktriangle on the right and a white triangle on the left,to test aspects of the pull-down logic software.Triangle Flashing: This testsignal also puts two opposing black and white triangles on the screen, but it flashes them at ahigh frame rate, to test the 3/2 pull-down editdetection and other aspects of the processor andinterpolation software.Ramp/Square: This complex patternuses a variety of fixed and pulsating gray-scaletests to test different aspects of the 3/2 pull-down edit detection and other aspects of theprocessor and interpolation software.The OUT ASPECT RATIO line sets theaspect ratio for the input source currently being adjusted.To make a change from the default setting, press the‹/›Navigation Buttons D©. Remember thatthis setting impacts the actual playback only. The on-screen menus will always be output as a 4:3 signal,though they may be stretched to 16:9 by a settingavailable in your video display.BRIGHTNESS: The changes to this settingare similar to the Brightness control on your display,changing the video level. If circumstances are suchthat a source has a low signal and appears dark,you may wish to change this setting, but be carefulnot to increase it to the point where the video dis-play is over-driven into clipping or blooming.CONTRAST: The changes to this setting aresimilar to the Contrast control on your display,changing the black level to compensate for poorcontrast.SATURATION: The changes to this settingare similar to the Color control on your display,andmay be used as needed to compensate for over- orunder-color-saturation.When all settings on this submenu page that requireadjustment have been made, use the ⁄/¤Navigation Buttons D©to move the on-screen cursor next to PAGE 1 and then press the OK/Enter Button Eor the Set Buttonœto return to the previous ADVANCEDCONFIGURATION settings page, or pointthe on-screen cursor at TO VIDEO MAIN toreturn to the VIDEO MAIN menu.Audio SetupThis menu allows you to configure the tone controls.If you do not wish to change any of those settings atthis time, proceed to the next menu screen. To makeconfiguration changes to those parameters, first make certain that the MASTER MENU is on screenwith the cursor pointing to the AUDIO SETUPline, and press the OK/Enter Button Eor the SetButtonœ. The AUDIO SETUP menu(Figure 8) will appear.Figure 8The first line controls whether or not the bass/trebletone controls are in the signal path. The normal defaultis for them to be in-line, but if you wish to removethem from the circuit for “flat” response, first makecertain that the cursor is pointing to the TONE lineon the menu and press the ‹/›NavigationButtons D©so that OUT is highlighted.If you wish to leave the tone controls in the signalpath, the amount off boost or cut for bass and treblemay be adjusted up to ±12dB in 2dB steps by press-ing the ⁄/¤Navigation Buttons D©so that the cursor is next to BASS or TREBLE,depending on which setting you wish to adjust. Next,press the ‹/›Navigation Buttons ountil thedesired setting is shown.When all desired changes have been made on thismenu, press the ⁄/¤Navigation ButtonsD©so that the cursor is next to the BACKTOMASTER MENU line; press the OK/EnterButton Eor the Set Buttonœ.Surround SetupThe next step is to set the surround mode you wish to use with the input that was previously selected inthe IN/OUT SETUP menu. Since surroundmodes are a matter of personal taste, feel free toselect any mode you wish – you may change it later.However, to make it easier to establish the initialparameters for the AVR 745, we suggest Logic 7(Cinema or Music) for most analog inputs. In the caseof inputs such as a CD Player, Tape Deck or Tuner,you may wish to set the mode to Stereo (“SurroundOff”), as they are not typically used with multichannelprogram material, and it is unlikely that surround-encoded material will be used. Alternatively, the Logic 7Music mode is a good choice for stereo-only sourcematerial.See page 41 for more information on avail-able surround modes.For digital program material, the AVR will always exam-ine the data stream and automatically select a DolbyDigital or DTS mode,as applicable.To begin the surround setup process,from theMASTER MENU (Figure 1), press the ⁄/¤Navigation Buttons D©until the cursor is nextto the SURROUND SELECT line. Press theOK/Enter Button Eor the Set Buttonœuntilthe SURROUND SELECT menu (Figure 9) is on the screen.Figure 9The first line on the menu allows you to select theinput for which the specific surround settings will be applied. Press the ‹/›Navigation ButtonsD©to select the input source to be configured.The AUDIO IN-PORT and AUDIO INlines are for display only and may not be changedthrough the SURROUND SETUP menu. TheAUDIO IN-PORT displays the physical con-nection source for the current active input, and theAUDIO IN line shows the signal type present.Note that an UNLOCK message in the AUDIOIN line indicates that a digital physical input sourcehas been selected, but that no data stream is present.When the input selection has been made, press the⁄/¤Navigation Buttons D©to move tothe next configuration line.The ADC SAMPLING line is where you deter-mine whether the unit’s upsampling feature is turnedon or off. The default setting of 48kHz puts thefeature in a bypass, or “off,” mode and will pass digitalaudio data through the DSP at its native sample rate.To process incoming 44.1kHz signals at a higher res-olution, upsampled 96kHz sample rate, press the ‹/›Navigation Buttons D©once so that96kHz is highlighted.When the desired setting has been made, or if noadjustment is required at this line,press the ⁄/¤Navigation Buttons D©to move to the nextconfiguration line.The SURR MODE and SELECT lines arerelated, as they guide you to the choice of the sur-round mode that will be activated whenever the inputbeing configured is selected.At the SURR MODE line,press the ‹/›Navigation Buttons D©to select the surroundmode group (such as Dolby modes, DTS modes,Logic 7 modes, and DSP or Stereo modes) that isapplicable to the input source. After making a selec-tion, press the ⁄/¤Navigation Buttons D©to move to the SELECT line.** SURROUND SETUP ** SOURCE: VIDEO 1AUDIO IN PORT: ANALOGAUDIO IN: PCM 44.1kHzADC SAMPLING: 48K 96KSURR MODE: LOGIC 7SURR SELECT: MUSIC 5.1DEFAULT SURR: LASTSURROUND CONFIGDOLBY SURR SETUPBACK TO MASTER MENU➔ * AUDIO SETUP * TONE :IN OUTBASS :0TREBLE :0BACK TO MASTER MENU→→SYSTEM CONFIGURATION 27SYSTEM CONFIGURATION 27AVR 745 OM 5/15/06 5:00 PM Page 27
SYSTEM CONFIGURATIONSYSTEM CONFIGURATION28 SYSTEM CONFIGURATION28 SYSTEM CONFIGURATIONAt the SELECT line, you are able to choose thespecific mode to be used from within the major sur-round mode group. The choice of modes is governedby the input type (as some modes such as DolbyDigital or DTS-ES are not available for analogsources), as well as by the speaker configuration,since some modes are only available when a full 7.1speaker complement is present. The full list of avail-able modes is detailed in the surround mode chart onpage 41. In addition, you may also use the settings inthe SURROUND CONFIG menus to deletemodes you do not normally use from the availablechoices.When both a surround mode group and a specificsurround mode have been selected, press the ⁄/¤Navigation Buttons D©to move to the nextconfiguration line.The DEFAULT SURR mode line is where youchoose the mode that is activated when a digitalsource is selected. The factory default setting ofLAST will activate the last-used mode for any digi-tal source. If you prefer to always have a digital sourceswitch to the specific mode encoded by digital dataflags in the incoming audio data stream, press the‹/›Navigation Buttons D©so thatORIGINAL appears.Before proceeding to the SURROUND CONFIGline, it is worth noting that the settings in the sub-menus attached to that line may require a consider-able amount of time to complete. Although they areuseful in that they allow you to customize the list ofsurround modes that appear in normal use of the AVR,you may wish to bypass those settings at this time sothat you may complete the configuration process. Youmay return to this menu line at a later time, once youhave had a chance to listen to the various surroundmodes and determine which you want to “keep” andwhich you do not want to use. The settings in this lineare not primary controls and do not impact the waythe AVR “sounds.”To proceed to the SURROUND CONFIG line,press the ⁄/¤Navigation Buttons D©tomove to that line; otherwise, press it again to move to the DOLBY SURR SETUP line and skip to the instructions for that setting.The SURROUND CONFIG line is your gate-way to a broad range of surround mode configurations.To continue, press the OK/Enter Button Eon theTC 30 or the Set Buttonœon the ZR 10 remoteto go to the main SURROUND CONFIGmenu (Figure 10).Figure 10The LOGIC 7 GLOBAL line is the only itemon this menu page that is menu-specific, and it allowsyou to select whether or not Logic 7 will be the defaultsurround mode for any incoming audio signal. Thedefault setting is OFF, which chooses the nativemode. Press the ‹/›Navigation Buttons D©so that ON appears, to activate the global Logic 7setting for this input.The remaining five items in this menu are global set-tings that take you to a submenu listing the individualsurround modes available within the selected modegroup. To select a surround mode list, press the⁄/¤Navigation Buttons D©until the on-screen cursor is pointing to the desired mode, andthen press the OK/Enter Button Eon the TC 30or the Set Buttonœon the ZR 10 remote. Withineach menu, press the ⁄/¤Navigation ButtonsD©to move the cursor up and down throughthe list, and then press the ‹/›Navigation ButtonsD©to turn the mode “ON” or “OFF.”• When a mode is ON,the mode will appear in allmenu selections whenever you are changing thesurround mode.•When a mode is OFF,the mode will not appear.• Some modes, such as Dolby Digital, DTS and theStereo mode in the PCM menus,are not defeatable.A complete list of the AVR 745’s surround modesmay be found on page 41, but here are some itemsthat will help you decide which modes you wantincluded in your setup, and which modes you maywish to turn off.• The DOLBY MULT CONFIG group con-tains the surround modes available when a multi-channel Dolby Digital, encoded source is present.This includes both the native Dolby Discrete mode,which cannot be turned off, as well as other modeswhich may be applied as post-processing on thesource and system speaker configuration.• The DOLBY 2.0 CONFIG group containsthe surround modes available when a two-channelDolby Digital-encoded source is present. Thisincludes both the native Dolby Discrete mode, whichcannot be turned off, as well as other modes whichmay be applied as post-processing on the sourceand system speaker configuration.• The DTS CONFIG group contains the sur-round modes available when a DTS-encoded digitalsource is present. This includes both the native DTSDiscrete mode, which cannot be turned off, as wellas other modes which may be applied as post-processing on the source and system speaker configuration.• The PCM 44.1/48kHz CONFIGgroup contains the surround modes available whena PCM digital data stream is present. This includesnot only PCM sources from DVD or CD players, butalso all two-channel analog sources that are in use,as they are converted to PCM within the AVR 745.The modes available include the proprietary Dolbymodes (including Dolby Headphone and DolbyVirtual Speaker), DTS processing, our own Logic 7modes, the conventional “DSP” modes (such as“Hall” and “Theater”) and the “Stereo” modes.• The PCM 96kHz CONFIG group containsthe surround modes available when a PCM digitaldata stream is present. This includes not only 96kHzPCM sources from DVD or CD players, but also alltwo-channel analog sources when 96kHz ischosen in the ADC SAMPLING mode line inthe SURROUND SETUP menu. The modesavailable include the proprietary Dolby mode (including Dolby Headphone and Dolby VirtualSpeaker), DTS processing, our own Logic 7 modes,the conventional “DSP” modes (such as “Hall” and“Theater”) and the “Stereo” modes.When all surround modes that are not required havebeen turned off, press the ⁄/¤NavigationButtons D©until the on-screen cursor is point-ing to BACK TO SURROUND CONFIG;then press the OK/Enter Button oon the TC 30or the Set Buttonœon the ZR 10 remote.The final item on the SURROUND SETUPmenu is the DOLBY SURR SETUP line.When the on-screen cursor is at this line,press theOK/Enter Button oon the TC 30 or the SetButtonœon the ZR 10 remote to call theDOLBY SURROUND menu (Figure 11) up on the screen.Figure 11With the exception of the Night mode setting, which is global and applies to all inputs,the settings on this page may be set individually for each input, butthey are only active when the Dolby Pro Logic II or** DOLBY SURROUND **MODE: DOLBY PLIIx MUSICCENTER WIDTH : 3DIMENSION : 0PANORAMA: OFF ONNIGHT: OFF MID MAXBACK TO SURROUND SETUP➔ ** SURROUND CONFIG **LOGIC 7 GLOBAL:OFFDOLBY MULTI CONFIGDOLBY 2.0 CONFIGDTS CONFIGPCM 44.1/48kHz CONFIGPCM 96k CONFIGBACK TO SURROUND CONFIG ➔ AVR 745 OM 5/15/06 5:00 PM Page 28
Dolby Pro Logic IIx modes are in use. Press the ‹/›Navigation Buttons D©to select the desiredDolby Pro Logic mode for adjustment, and then pressthe ⁄/¤Navigation Buttons D©to movethrough the three choices. Press the ‹/›NavigationButtons D©to adjust the settings, as desired.The three Dolby surround settings are:• CENTER WIDTH:This setting adjusts thebalance of the vocal information in the front sound-stage between the center and front left/right speak-ers. The lower settings spread the center channelsound more broadly into the left and right channels.A higher number (up to “7”) produces a tighter cen-ter channel presentatioin.• DIMENSION: This setting alters the perceiveddepth of the surround field by creating a shallowerpresentation that appears to move sounds towardthe front of the room, or a deeper presentation that appears to move the center of the sound fieldtoward the back of the room. The setting of “O” is aneutral default, with the range of adjustment shownas “R-3” for a deeper, rear-oriented sound to “F-3”for a shallower, front-oriented sound.• PANORAMA: Switch this setting to ON to add an enveloping wraparound presentation thatincreases the perception of sound along the sides of the room.When any needed adjustments to the parameter set-tings for the Dolby Pro Logic II and Dolby Pro Logic IIxMusic modes have been made, or if no adjustment to those settings are required, press the ⁄/¤Navigation Buttons D©to move to the last line on the menu.The NIGHT line adjusts the settings for the Nightmode, which is only available when specially encodedDolby Digital sources are being played.The Night mode is a feature of Dolby Digital that usesspecial processing to preserve the dynamic range andfull intelligibility of a movie soundtrack, while reducingthe peak level. This prevents abruptly loud transitionsfrom disturbing others, without reducing the sonicimpact of a digital source.To adjust the Night mode setting, make certain that the cursor is on the NIGHT line of the DOLBYmenu. Next, press ‹/›Navigation ButtonsD©to choose between the following settings,as they appear in the on-screen display:OFF: When OFF is shown, the Night mode willnot function.MID: When MID is shown, a mild compressionwill be applied.MAX: When MAX is shown, a more severe com-pression algorithm will be applied.We recommend that you select the MID setting as a starting point and change to the MAX setting later,if desired.When all settings on the DOLBY SURROUNDmenu have been competed, press the ⁄/¤Navigation Buttons D©until the cursor is nextto BACK TO SURROUND SETUP andpress the OK/Enter Button oon the TC 30 or theSet Buttonœon the ZR 10 remote. You may thenmake any additional changes to the available optionsfrom that screen, or use ⁄/¤Navigation ButtonsD©to move the cursor to the BACK TOSURROUND CONFIG menu and press theOK/Enter Button oon the TC 30 or the SetButtonœon the ZR 10 remote again to back upone menu.At the main SURROUND SETUP menu, youmay change the SOURCE to make adjustments to another input, or when all input sources have beenconfigured, use ⁄/¤Navigation Buttons D©to move the cursor to the BACK TO MASTERMENU and press the OK/Enter Button oon theTC 30 or the Set Buttonœon the ZR 10 remoteto return to the main menu so that you may move tothe next step in configuring your AVR 745.Using EzSet/EQIIThe AVR 745 includes the latest Harman KardonEzSet/EQII technology to automatically configure yoursystem to deliver the best possible performance basedon your specific speaker selection, where the speakersare placed in the room and the acoustic influences inyour listening room. By using a series of test signalsand the processing power of a Texas Instruments™DA 610 digital signal processor, running at 250mHz.EzSet/EQII eliminates the need for manual adjustmentof speaker “size”, crossover, delay and output level set-tings while it adds the power of proprietary algorithmsand configurable digital filters to deliver optimal soundreproduction.In addition to making system setup quick and easy,EzSet/EQII is more precise than manual settings.WithEzSet/EQII, you are able to calibrate your system in afraction of the time it would take to enter the settingsmanually, and with results that rival those achieved withexpensive test equipment and time-consuming proce-dures.The end result is a system-calibration profilethat enables your new receiver to deliver the best possible sound, no matter what type of speakers youhave or what the properties of your listening room are.EzSet/EQII includes a number of improvements to theoriginal version, including the ability to set up to threedifferent sets of EQ measurements and the capabilityto handle dual subwoofers. The menu and setup sys-tem not only delivers improved precision for all meas-urements, but it also guides you through the step-by-step process of EQ Design. With EzSet/EQII, you cannow “test drive” the settings by listening to the resultsof the EzSet/EQII process before entering the settingsinto the system memory.We recommend that you take advantage of the precision of EzSet/EQII to calibrate your system,but if desired you may also make any of the configuration settings manually, or trim the settingsprovided by EzSet/EQII by following the instructions on pages 33–38.Before starting EzSet/EQII, make certain that you haveconnected all speakers for your system and that youhave both the EzSet/EQII microphone and the exten-der rod handy. If you have a standard camera tripod,attach the extender rod to the tripod, and then screwthe microphone to the top of the rod. Place the tripodat your primary listening position, at least three feetfrom the nearest hard surface, and adjust it so that themicrophone is at or above ear level. If you do nothave a tripod, simply screw the extender rod into thebottom of the EzSet/EQII microphone.Next, plug the microphone into the EzSet/EQIIMicrophone Jack Jlocated behind the Front-Panel Control Door 9.Finally, before going further, make certain that the pro-gram volume is at -25dB. If there is a volume or“level” control on your subwoofer, make certain that itis set to at least the mid-point, if not a bit higherTo start the EQ Design process, first navigate to theEZSET/EQ MAIN menu (Fig. 12) by pressingthe OSD Button Con the ZR10 remote or theMenu Button Aon the TC 30. Press the ⁄/¤Navigation Buttons ountil the cursor is pointingto EZSET/EQ in the MASTER MENU.Press the OK/Enter Button oon the TC 30 or theSet Button œto bring the new menu to the screen.Figure 12There are four choices in the EZSET/EQMAIN menu, three of which are relevant at thistime.

Follow theinstructions on pages 33 to 38 for the items youwish to set manually. During that process, a mes-sage may appear reminding you to run EzSet/EQ,which you may ignore at this time since you willreturn to the EzSet/EQ menu at the conclusion ofyour manual adjustments.After completing all manual settings, press the⁄/¤Navigation Buttons D©to move the cursor to the BACK TO EZSET/EQMAIN line and then press the OK/Enter ButtonEon the TC 30 or the Set Buttonœon the ZR 10 remote. When that menu (Figure 12)returns to the screen, press the ⁄/¤NavigationButtons D©again to move the cursor to theMANUAL EQ DESIGN line and then pressthe OK/Enter Button Eon the TC 30 or theSet Buttonœon the ZR 10 remote. A messagewill appear,reminding you to manually set the sys-tem parameters, but since you have just done that,make certain that the cursor is at the CONTIN-UEline and press the OK/Enter Button Eonthe TC 30 or the Set Buttonœon the ZR 10remote.Follow the steps shown below to completethe EzSet Design process.• If you wish to enter the settings for speaker configu-ration, channel output adjustment and delay timesmanually,press the ⁄/¤Navigation ButtonsD©to move the cursor to the EZET/EQMANUAL SETUP line and then press theOK/Enter Button Eon the TC 30 or the SetButtonœon the ZR 10 remote. This will takeyou to the MANUAL SETUP menu, whereadditional submenus contain the configurationadjustments. Skip to page 33 for details on manual setup.• The EZSET/EQ PRESET SELECTline is used to recall one of the three EQ Designsthat may be stored with different settings. For moreinformation on using the Preset Selections, seepage 38 or 48.EQ Design is done in a series of steps, with the FarField measurements first, followed by the Near Fieldmeasurements and, finally, the Subwoofer measure-ments. In each case, the process is the same: the on-screen menus will direct you to place the micro-phone in a specific location, and when that portion ofthe process is started, test tones will be sent to thespeaker or speakers being measured. The system willthen pause slightly as the results of the measurementare calculated and stored in system memory.If the step was successful, an on-screen message willreport the test results and direct you to the next step.If the step did not produce acceptable results, an errormessage will appear, suggesting the adjustmentsneeded to correct the problem and start a re-test.During each EQ Design step, you have the option to perform the tests for that specific portion of theprocess, or you may skip the settings and move toanother step or return to the EZSET/EQMAINmenu (Figure 12).When the complete EQ Design process is complete,you will be given an opportunity to “test drive” the set-tings by listening to a source with the room equaliza-tion filters applied. In order to take advantage of thisfeature, before beginning the EQ Design, make certainthat a source is playing with program material you arefamiliar with. If necessary, exit the menu system at thistime to select and start the playback, and then returnto EzSet/EQ. The source will mute during the EQDesign, but will return when it is time for the “testdrive.”Step 1. The EZSET DESIGN STEP 1menu (Figure 13) will appear with instructions as towhere to place the microphone. As noted on thescreen, use the Volume Control )r to adjustthe volume level to –25dB, as shown on the line thatappears at the bottom of the menu when the volumeis adjusted. Press the OK/Enter Button Eon theTC 30 or the Set Buttonœwhen the volume isset to the proper level.Figure 13The final menu screen before the EzSet/EQII processstarts is a warning screen (Figure 14) that serves as areminder to keep the room as quiet as possible whilethe system is in use.Figure 14Extraneous noise of any kind may adversely affect theaccuracy of the system’s results. Do not talk while thetest tones are circulating and, if possible, turn off anyventilation systems if the noise from the airflow is loudenough for you to hear. Should an outside noise suchas a phone ringing occur during the test process,werecommend that you rerun EzSet/EQII. To begin theEzSet/EQII Far Field measurements, press the ‹/›Navigation Buttons D©so that ON is high-lighted in reverse video, and press the OK/EnterButton Eon the TC 30, or the Set Buttonœ.NOTE: Once the EzSet/EQII process starts, the vol-ume control and Standby/Off switches are temporarilydisabled while the tests are in progress. Do not adjustthe volume or turn the unit off until you see the on-screen message change to indicate that EzSet/EQIIis finished.At this point, a series of test tones will circulate amongall the speakers in your system. While this is happen-ing, the AVR 745 is reading the signal to determinewhich speaker positions are active, what type ofspeaker is present at each active position and whatthe distance is from the listening position to eachspeaker, and to begin to build a profile of the impact ofthe room’s acoustics on the qualityof audio reproduc-tion. When the tones stop, the system will pause for aslong as a minute while the processor makes its calcu-lations based on the results of the signal measure-ments. Do not be alarmed if the “WARNING” messageremains on the screen after tones stop until a resultsmessage is displayed.

NOTE: While these tests detect whether a speaker isconnected to a particular output, they cannot deter-mine whether the speaker is in the correct position.(For example, it can tell whether a speaker is connectedto the Surround Right output, but it cannot tell whetherthe speaker is on the right or left side of your listeningroom.) For that reason, we strongly recommend thatyou try to listen carefully to make sure that the testtone circulates in a clockwise rotation, starting with thefront left speaker, to the center, to the front right, andso on to the subwoofer. If the tone is heard from aspeaker that seems as though it is out of sequence,such as the tone coming from the surround left speakerwhen the next speaker in the sequence should be thesurround right speaker, exit the EzSet/EQII systemwhen the test sequence is completed and use themanual output level tone adjustment process, as out-lined on page 37, to determine which, if any, speakeris incorrectly connected.When the Far Field tests are complete, a messagescreen will appear to indicate whether the procedurewas successful or not. In most cases, there will not beany problems and you will see the message shown inFigure 15 on your screen.Figure 15If the speaker positions shown match the actualspeaker layout in your system, confirm that the cursor is pointing to CONTINUE TO NEARFIELD and press the OK/Enter Button Eonthe TC 30 or the Set Buttonœto take the NearField measurements in Step 2.If the measurements are not successful, due to amissing or malfunctioning speaker, an ERRORmessage will appear as shown in Figure 16.EzSet/EQII is programmed to look for speaker pairs atthe front left/ front right, surround left/surround rightand surround back left/surround back right positions. Ifthe test results indicate that one, but not both, of thespeakers in any of these pairs is present, the menuwill show NO next to the speaker position where thetests did not report back that a speaker is present.Should this message appear, make note of the sus-pect speaker location, exit the menus and turn thereceiver off. Check all speaker wire connections andthen rerun EzSet/EQII.Figure 16In some cases, the system may not function properlydue to overly high output levels. When this occurs, youwill see the message shown in Figure 17.Figure 17If the EQ DESIGN OVERLOAD messageappears, first press the OK/Enter Button Eon theTC 30 or the Set Buttonœon the ZR 10 remote.This will take you back to the EQ DESIGNSETP 1 ERROR menu. Make certain that thecursor is pointing to REPEAT TEST and pressthe OK/Enter Button Eon the TC 30 or the SetButtonœon the ZR 10 remote again. At theEZSET DESIGN STEP 1 menu, lower thevolume by at least 6dB and follow the steps describedabove to run the EzSet/EQII system again. Dependingon the amount of the overload, you may need torepeat the process more than once to achieve satisfactory results.Step 2. When the Far Field measurements are com-pleted, the next step is to take the Near Field meas-urements. These measurements enable EzSet/EQII toproduce the most accurate settings for high-frequencyequalization. The Near Field measurements are similarto the Far Field tests, except that the system will “listen”to only one speaker at a time, rather than sending thetest signals to all speakers in rotation.Figure 18When it first appears, the NEAR FIELDMENU (Figure 18) will show a list of all the possiblespeakers and NO next to each speaker positionwhere the Far Field measurements detected a speaker.The Near Field measurements should be made foreach of those speakers to create a successful EQ Design. To select a speaker position for measure-ment, press the ⁄/¤Navigation ButtonsD©to move the cursor next to the desiredspeaker position and then press the OK/Enter ButtonEon the TC 30 or the Set Buttonœon the ZR 10 remote.Before the test begins, an informational message willappear (Figure 19).Figure 19Follow the instructions and place the microphoneabout halfway between the speaker and the listeningposition where the microphone was placed during theFar Field measurements. With the cursor pointing toCONTINUE, press the OK/Enter Button Eon the TC 30 or the Set Buttonœon the ZR 10remote control.When the WARNING message appears, press the ›Navigation Button D©to start the test.A short tone will be heard from the speaker beingtested, and after a short pause the on-screen menuwill show a message to inform you of whether the testwas successful or not.• If the test was successful and there are morespeaker positions for which a Near Field measure-ment is required, press the OK/Enter Button Eon the TC 30 or the Set Buttonœon theZR 10 remote to return to the NEAR FIELDMENU.Speaker positions where the Near Fieldmeasurement has been completed will showDONE to the right of the position name. Press the⁄/¤Navigation Buttons D©to select aposition where NO still appears and repeat thesteps shown above until a Near Field measurementhas been taken at all speaker positions.• If the test was successful and all Near Field meas-urements have been completed, the on-screenmessage will direct you to the Subwoofer measure-ments.

you wish to choose another option to skip the sub-woofer measurements and either complete theEQ Design or return to the EZSET/EQMAIN menu.• If there was an error during the test, the DesignStep 2 Error message will appear. Follow the on-screen instructions to check speaker connections (if no sound was heard from the speaker during the test), check the microphone placement to makecertain it is no further than half the distance from thespeaker to the listening position and pointing directlyat the speaker, or increase the volume by 5dB. Aftertaking the corrective steps, make sure the cursor ispointing to REPEAT TEST and press theOK/Enter Button Eon the TC 30 or the SetButtonœon the ZR 10 remote. Select thespeaker again and repeat the steps as needed untila successful measurement is made.Steps 3 and 4: The third and fourth steps in theEzSet/EQ II Design process are the measurement forthe subwoofers, if present. Although the subwoofersare generally considered one speaker position, sincethe AVR 745 may be used with two subwoofers, twoseparate measurement steps must be combined for acomplete EQ Design.When the SUBWOOFER DESIGN messageappears, make certain that the cursor is pointing toCONTINUE TO SUB DESIGN and pressthe OK/Enter Button Eon the TC 30 or the SetButtonœon the ZR 10 remote control. TheEZSET DESIGN STEP 3 (Figure 20)message will appear.Figure 20Follow the instructions (using the extender rod if nec-essary), to make sure that the microphone is at earlevel and to the left of where the microphone wasplaced during the Far Field measurements. Press theOK/Enter Button Eon the TC 30 or the SetButtonœon the ZR 10 remote to continue.When the WARNING message appears onscreen, press the ‹/›Navigation Buttons D©to start the test. The test tone will be sent to the sub-woofer(s) and the system will then pause slightly toperform the needed calculations. When the calcula-tions are complete, the EZSET DESIGNSTEP 4 message will appear.The instructions here are identical to those in Step 3except that the microphone should be placed to theright of where it was during Far Field measurements.Press the OK/Enter Button Eon the TC 30 or theSet Buttonœon the ZR 10 remote to continue.When the subwoofer tests in Steps 3 and 4 are com-plete, a message (Figure 21) will appear after a briefpause to display the results.Figure 21• If the tests were successful, the message will showthe number of subwoofers, as shown in Figure 21.You may either press the OK/Enter Button Eonthe TC 30 (or the Set Buttonœon the ZR 10remote) to continue to the next step and concludethe EzSet Design process, or press the ⁄/¤Navigation Buttons D©and then theOK/Enter Button Eon the TC 30 (or the SetButtonœon the ZR 10 remote) to either repeatthe subwoofer test or return to the main EzSet/EQmenu. In most cases you should select “Continue.”• If the tests were not successful, a message similarto Figure 21 will appear, except that the top line will flash DESIGN STEP 3/4 ERROR.Follow the suggestions in the message to verify thatthe subwoofer(s) is properly connected and that themicrophone is in the proper position, and increasethe volume level by 5dB.Then, press the OK/EnterButton Eon the TC 30 or the Set Buttonœon the ZR 10 remote to repeat the test as often asneeded until a successful result is achieved.Step 5: When all measurements are successfullycompleted, the final step in the EzSet Design processis to save the settings into the AVR 745’s memory.You may program up to three different EQ settings toaccommodate differences in placement of the micro-phone to reflect alternate listening positions, but werecommend that you create two settings and leaveone memory in the “bypass” mode so that you havethe ability to compare the two equalized settingsagainst a “straight through” setting that has no equal-ization applied.At the conclusion of the measurements for anEQ Design, make certain that the EZSET/EQDESIGN DONE menu (Figure 22) is on yourscreen. It will appear when you are done with theSubwoofer design, or when you “skip” through theNear Field and/or Subwoofer steps.Figure 22The “test drive” feature allows you to listen to thesource that was playing before the EzSet/EQ Designprocess was initiated, and it is a good way to makesure that you are pleased with the results. The“Warning” refers to the fact that the volume level mayhave been raised during the Design process, so it isalways a good idea to lower the volume a bit. You mayalways raise it once the playback starts.With the cursor pointing to CONTINUE, pressthe OK/Enter Button Eon the TC 30 or the SetButtonœon the ZR 10 remote, and playback willresume while the on-screen menu changes to theDESIGN PREVIEW page (Figure 23).Figure 23• If you are pleased with the sound, press theOK/Enter Button Eon the TC 30 or the SetButtonœon the ZR 10 remote to move to thenext screen and store the settings.• If the sound is not to your liking, press the ⁄/¤Navigation Buttons D©so that the cursor isnext to NO and then the OK/Enter Button Eonthe TC 30 or the Set Buttonœon the ZR 10remote. Follow the on-screen prompts in the menusto return to the EZSET/EQ MAIN menuand repeat the EQ Design process.• If this is your first attempt at running EzSet/EQII,we recommend that you save the settings,even ifyou are not sure whether you like them, then rerunthe EQ Design process again. Since the AVR 745 isable to store multiple EQ Design settings, this will giveyou the opportunity to compare two different designsto the bypass mode with no equalization applied. Youmay then select the preset you like best.If you proceed to store the settings,the next menu willlet you select which memory position will be used(Figure 24). * DESIGN PREVIEW * EQ design has been completed.

Figure 24When the PRESET SAVE SELECTIONscreen appears for the first time, BYPASS willappear next to all memory preset position. This indi-cates that no settings are stored in any position. Pressthe ⁄/¤Navigation Buttons D©to movethe cursor next to the preset where you wish to save the settings and then press the OK/Enter Button Eon the TC 30 or the Set Buttonœon the ZR 10 remote. If you have previously stored anEQ Design and wish to enter new settings to that posi-tion, a warning message will appear, reminding youthat the existing settings for that preset will be over-written. If that message appears, press the OK/EnterButton Eon the TC 30 or the Set Buttonœon the ZR 10 remote to continue, or press the ⁄/¤Navigation Buttons D©to move the cursornext to NO and then the OK/Enter Button Eonthe TC 30 or the Set Buttonœon the ZR 10remote to return to the PRESET SAVESELECTION screen so that you may selectanother memory preset.While an EQ Design is being stored, a message willappear to remind you that the memory storage is inprocess. When the settings are stored, you will bereturned to the EZSET/EQ MAIN menu.Once a setting is stored, the next time you completean EQ Design and are at the PRESET SAVESELECTION page, the word DESIGN willappear next to any preset where you have previouslystored data.At this point, you may either follow the prompts in themenu to exit back to another menu, create another EQ Design, or use the manual setup menus to fine-tune an EQ Design.Thanks to EzSet/EQII, the settings for speaker “size,”speaker crossover, channel output and individual chan-nel delay time have been automatically set and requireno further adjustment. In addition, EzSet/EQII also per-forms a complete room equalization that tailors thesystem’s performance for the best possible sound withyour combination of speakers, speaker placement androom acoustics. The next few pages in this manualdetail the procedure for manually entering systemdata, but unless you want to view the setting informa-tion and make an adjustment, you are now ready toenjoy the finest in home theater and music reproduc-tion. Go to page 39 for complete information on operating your AVR 745.Manual SetupIn most cases it is simpler, easier and more accurateto let EzSet/EQII take care of entering the systemparameters for speaker “size”, speaker crossover,channel output and individual channel delay time.However, if you feel that your listening room or systemcomponents are best suited to manual entry of thesesettings, the AVR 745 also allows you to enter or trimany of these traditional system parameters. Even if youdo make the settings manually, we recommend thatyou run the EzSet/EQII tests first so that a baselinesetting is established, and then make your adjustmentsfrom there. Note that once EzSet/EQII has been run,you do not need to adjust all system settings, onlythose that you want to adjust.To view or change the current EQ Design settings,make certain that the EZSET/EQ MAINmenu (Figure 12) is on the screen. Press the ⁄/¤Navigation Buttons D©to move the cursornext to EZSET/EQ MANUAL SETUP andthen press the OK/Enter Button Eon the TC 30or the Set Buttonœon the ZR 10 remote. TheEZSET/EQ MANUAL SETUP menu(Figure 25) will appear on the screen.Figure 25If you have already run the EzSet/EQII calibration sys-tem, the first line of the menu enables you to hear the difference between the settings established byEzSet/EQII. The default setting is ON, which plays the incoming source with the EzSet/EQII settings. Tohear the system in a Bypass mode, with none of theequalization filters in the circuit path, press the ‹/›Navigation Buttons D©so that OFF is high-lighted. Once changed, this setting will remain until you change it again in this menu. While you may wantto use this menu option to hear the difference thatEzSet/EQII makes, we recommend that you leave the setting on to take advantage of the benefits ofEzSet/EQII’s advanced room correction technology.The EZSET ADJUST line on the menuenables you to set the system’s “Filt,” or high-frequen-cy boost. To make this adjustment, first make sure thatthe EZSET EQ line is set to ON, as this item isnot available when EzSet/EQII is not in the signal path.To adjust the tilt setting, press the ⁄/¤NavigationButtons D©to move the cursor next to EZSET ADJUST and then press the OK/EnterButton Eon the TC 30 or the Set Buttonœon the ZR 10 remote. The EZSET ADJUSTmenu (Figure 26) will appear on the screen.Figure 26Press the ‹/›Navigation Buttons D©tochange the setting as needed. When the adjustment is complete, press the ⁄/¤Navigation ButtonsD©to move the cursor next to BACK TOMANUAL SETUP and then press the OK/EnterButton Eon the TC 30 or the Set Buttonœon the ZR 10 remote.Note on Manual Setup Menus: Each manual setupmenu (SPEAKER SIZE/X-OVER,DELAY ADJUST and CHANNELADJUST)includes a line that reads EZSETSETTINGS.When the default setting of OFF isshown, you are able to make any required adjust-ments that are available on that menu. However, youmay change the setting to ON at any time to recall the settings estab-lished when EzSet/EQII was last run. It is also impor-tant to note that when the EzSet/EQII settings are inuse, the AVR will not allow any changes to be made.To trim the settings, press the ⁄/¤NavigationButtons D©until the cursor is in the EZSETSETTINGS line on the menu in use and pressthe ‹/›Navigation Buttons D©to changethe setting to OFF. This will allow you to makechanges to the settings in that menu.Speaker Size MenuAlthough most listeners will prefer to take advantage of the accuracy and speed of EzSet/EQII to make allof the necessary speaker adjustments, advanced usersmay wish to experiment with how different combina-tions of settings sound in their home theater environ-ment or to use settings other than those calculated by EzSet/EQII, to accommodate personal listening preferences.The menu system used in your AVR 745 differssomewhat from conventional speaker setup menus inthat it consolidates the speaker “size” and crossoverinto one convenient menu. Even if you are familiar withmaking these adjustments, it is strongly recommendedthat you read the following section of this manual.* EZSET ADJUST * TILT: 0dB BACK TO MANUAL SETUP →→* EZSET/EQ MANUAL SETUP * EZSET/EQ: OFF ON EZSET ADJUST SPEAKER SIZE/X-OVER DELAY ADJUST CHANNEL ADJUST BACK TO EZSET/EQ MAIN →→* PRESET SAVE SELECTION * PRESET 1: DESIGN PRESET 2: BYPASS PRESET 3: BYPASS →→SYSTEM CONFIGURATIONSYSTEM CONFIGURATIONSYSTEM CONFIGURATION 33SYSTEM CONFIGURATION 33AVR 745 OM 5/15/06 5:00 PM Page 33
On the SPEAKER SIZE/X-OVERmenu(Figure 27), you have the option to change the type ofspeaker configured for each of the four speaker posi-tion groups, to change the crossover setting for anyone of those speakers, to adjust the setting point forthe low-pass filter that determines which frequenciesare sent to the subwoofer for low-frequency effects(LFE) signals, to change the subwoofer bass redirec-tion mode when the Front Left/Right speakers are setto Large and to change the setting for the subwoofersize. If, as recommended, you have first run theEzSet/EQII system, the settings established byEzSet/EQII will be displayed as a starting point for anymanual adjustments. You may reestablish those set-tings at any time during an adjustment on this menuby pressing the ⁄/¤Navigation Buttons D©until the cursor is on the EZSET SETTINGSline of the menu and then pressing the ‹/›Navigation Buttons D©so that ON is high-lighted in reverse video. Note, however, that once thisis done, any manual adjustments made will be lost and must be reentered.Speaker SizeAt each of the four speaker group positions, you havethe ability to select the speaker “size” and, when a“Small” speaker is selected, the frequency belowwhich low-frequency information is sent to the sub-woofer, as opposed to the speakers for the channelbeing adjusted. For that reason, before making the adjustments on the FL/FR,CENTER,SL/SR and SBL/SBR menu lines, it is impor-tant to know the frequency range for the speaker. Thisinformation is typically found in the “Specifications”section of the speaker’s owner’s manual. If you cannotfind the specification for the lowest frequency thespeaker can handle, start with the settings entered byrunning EzSet/EQII and then try one setting above orbelow the existing entry. We do not recommendchanging the crossover point more than that, due tothe possible impact that will have on the speaker’sperformance. If you do not have access to the owner’smanual for a particular speaker, you should be able to obtain the needed information from the Web site or customer service department of the speaker’s manufacturer.To view or change the current speaker size settings,make certain that the EZSET/EQ MAINmenu (Figure 12) is on the screen. Press the ‹/›Navigation Buttons D©to move the cursornext to SPEAKER SIZE and then press the OK/Enter Button Eon the TC 30 or the Set Buttonœon the ZR 10 remote control. TheSPEAKER SIZE menu (Figure 27) will appear on the screen.Figure 27On the SPEAKER SIZE menu (Figure 27),you will see a display of either the settings that were established when EzSet/EQII was run, or the factory default settings if you have not yet run the automated system.To change the setting for any of the four speaker posi-tions, press the ⁄/¤Navigation Buttons D©until the cursor points to the line where you wish tomake the change. Press the ‹/›NavigationButtons D©to change the setting, but note thatwhen you do this for the first time in the menu, awarning message (Figure 28) will appear in the on-screen display, reminding you to rerun EzSet/EQIIwhen you are finished with any speaker configurationchanges. This is necessary to make any level outputadjustments needed after the setting changes, so thatthe new configuration will be properly integrated.Figure 28The warning message will remain for five seconds andthen the SPEAKER SIZE menu will return tothe screen. At this point you may change the settingsto the “size” or crossover for any of the four speakerpositions using the Navigation ButtonsD©asshown above. The information below details the set-tings available for each of the speaker configurations.At each of the four speaker position lines, you havethe option to set the speaker size and crossover. Notethat the “size” does not refer to the speaker’s actualphysical size, but rather to the ability of the speaker toreproduce low-frequency information. If your speakersat any position are traditional full-range models capable of handling the full audio spectrum, selectLARGE. These speakers are called “large” sincethe low-frequency drivers required to play bass withoutstrain or distortion are typically eight to fifteen inches in diameter, in turn making the speaker cabinet largerthan those with small (or no) low-frequency drivers.When the speakers at a particular position are smallerfrequency-limited speakers without the ability to properlyreproduce low-frequency sounds, select SMALL.At all positions except for the front left/right speakers,you may also select NONE. This setting tells thesystem that no speakers are present at that position,allowing the AVR to select the correct surround modesthat are compatible with the number of speakersinstalled. For example, in order to use the Dolby DigitalEX, Dolby Pro Logic IIx, DTS-ES,Logic 7/7-channel and“7 Stereo” modes, you must have either LARGE orSMALL speakers entered as the setting for theBACK SURR channels.When LARGE is selected for any channel, a full-range signal will be sent to the speaker outputs forthat channel. For all speaker positions except the frontleft/right, when LARGE is chosen, no derivedsound will be sent to the subwoofer output, althoughin all cases the special low-frequency effects (LFE)signals available on 5.1 or 6.1 digital programs willalways be sent to the subwoofer output.When SMALL is selected for any channel, you mayalso enter a setting for the crossover frequency atwhich sound is divided between the frequency abovewhich sound is sent to the channel’s speakers andbelow which sound is sent to the subwoofer. Whenconfiguring a “small” speaker, choose the setting thathas the frequency closest to that of the lowest fre-quency the speakers in question are capable of han-dling. If one of the six available crossover points doesnot match, select the one that is above, but closest to,the speaker’s low-frequency limit.When there are no speakers available at a specificposition, select NONE.When this option is chosenfor the Center or Side Surround speakers,the soundthat would normally be sent to these channels will besplit between the front left and right speakers.When asystem does not include Center or Surround speakers,the use of Dolby Virtual Speaker as a surround modemay provide a sound field that simulates the presenceof these speakers. (See page 41 for more informationon the Dolby Virtual Speaker mode.)When NONE is selected for the Back Surroundspeakers, the 6.1/7.1-channel surround modes arenot available. If this is the case for your system, youmay wish to take advantage of the availability of theunused amplifier channel pair to power a second setof speakers in another room. (See page 51 for moreinformation on amplifier configuration.)Once any desired changes have been made to thespeaker size and/or crossover, press the ⁄/¤Navigation ButtonsD©to move the cursor toany other line in this menu to make a setting change,or go to the BACK TO MANUAL SETUPmenu and then press the OK/Enter Button Eonthe TC 30 or the Set Buttonœto continue withoverall configuration.

LFE Low-Pass Filter SettingThe LFE LP FLT line selects the frequency set-ting below which sounds that may be available from aspecial low-frequency effects (LFE) track are sent tothe subwoofer. In most cases, this setting will be setaccurately by EzSet/EQII but, should you wish to makea change from that setting or the 120Hz frequencythat is most commonly used in the creation of LFEchannels by motion picture sound mixers, after makingsure that the SPEAKER SIZE menu (Figure27) is on the screen, press the ⁄/¤NavigationButtons D©so that the cursor is pointing toLFE LP FLT.Press the ‹/›NavigationButtons D©to begin the selection process, andnote that the warningmessage (Figure 28) will appear,reminding you to rerun EzSet/EQII after all changeshave been made.When the SPEAKER SIZE menu returns tothe screen, press the ‹/›Navigation ButtonsD©to make your selection. When the desiredsetting appears, press the ⁄/¤NavigationButtons D©to move the cursor to any otherline on this menu where you wish to make a settingchange, or go to the BACK TO MANUALSETUP menu and then press the OK/EnterButton Ein the TC 30 or the Set Buttonœto continue with overall configuration.Sub Mode SettingWhen the Front Left/Right speakers are configured as“Large” and a subwoofer is detected by EzSet/EQIIor manually configured as being available, additionaloptions are available to further customize bass redirec-tion. To change these settings, first make sure that the SPEAKER SIZE menu (Figure 27) is onthe screen, and then press the ⁄/¤NavigationButtons D©so that the cursor is pointing toSUB MODE. Press the ‹/›Navigation ButtonsD©to begin the selection process, and note thatthe warning message (Figure 28) will appear, remind-ing you to rerun EzSet/EQII after all changes havebeen made.The following options are available:• The default setting for Large front left/right speakerswhen a subwoofer is present is SUB L/R+LFE.In this mode, all sounds below the crossover pointset on the LFE LP FLT line will be sent toBOTH the subwoofer and front left/right speakers.• To send only the LFE channel information to thesubwoofer, but have all other (“derived”) low-frequency sounds sent to the front left/right speakers, select the SUB (LFE) setting.• To have low-frequency information sent to the sub-woofer only when Large speakers are selected,choose SUB (L/R).This option is only avail-able when the unit is set to SURROUND OFFso that a pure analog audio path is provided.• When no subwoofer is present and Large speakersare configured for the front left/right position, selectNONE. This will route all low-frequency informa-tion to the front left/right speakers.When the SPEAKER SIZE menu returns tothe screen, replacing the warning message, press the‹/›Navigation Buttons D©to make yourselection. When the desired setting appears, press the⁄/¤Navigation Buttons D©to move thecursor to any other line on this menu where you wishto make a setting change, or go to the BACK TOMANUAL SETUP menu and then press theOK/Enter Button Ein the TC 30 or the SetButtonœto continue with overall configuration.Subwoofer ConfigurationThe AVR 745 is among the very few A/V receivers orsurround processors that are capable of feeding twosubwoofers, as well as the standard configuration of asingle subwoofer. Although one subwoofer is capableof delivering powerful bass, the use of two subwoofersin conjunction with EzSet/EQII expands the bassresponse over a wider listening area.The default setting for the AVR 745 is a single sub-woofer, but if you are using two subwoofers, it isimportant to change the setting on the NO. SUBSline. To do that, press the ‹/›Navigation ButtonsD©as needed so that the cursor is pointing toNO. SUBS, and then press the ‹/›NavigationButtons D©so that the number shown changesfrom 1to 2.Subwoofer SizeThe final setting on the SPEAKER SIZE menuenables you to change the setting for the subwoofersize. In the event that EzSet/EQII did not accuratelyenter the correct size, or if you wish to experiment with a different setting, first make sure that theSPEAKER SIZE menu (Figure 27) is on the screen; then press the ⁄/¤NavigationButtons D©so that the cursor is pointing toSUB SIZE and then press the ‹/›NavigationButtons D©to begin the selection process.Note that a warning message will appear for four seconds to remind you to rerun EzSet/EQII after all changes have been made.Select a setting that best matches the diameter ofyour subwoofer’s driver, or which provides the appro-priate high-pass filter setting for your system. In eachcase, the frequency of the high-pass filter determinesthe frequencies below which no information is sent tothe subwoofer:• The setting for an 8-inch/200mm driver activates a38Hz subwoofer high-pass filter.• The setting for a 10-inch/250mm driver activates a30Hz subwoofer high-pass filter.• The setting for a 12-inch/305mm driver activates a20Hz subwoofer high-pass filter.• The setting for a 15-inch/380mm driver activates a15Hz subwoofer high-pass filter.When all changes to speaker-related settings havebeen made, press the ⁄/¤ Navigation ButtonsD©until the cursor is on the BACK TOMANUAL SETUP menu; then press theOK/Enter Button Eon the TC 30 or the SetButtonœso that you may make any other adjust-ments to the system parameters. Remember to rerunthe EzSet/EQII system if any changes have beenmade to the settings in this menu, following theinstructions for using the Manual mode shown onpage 30.The speaker configuration settings may also be adjusteddirectly and without going into the OSD menu systemat any time using the TC 30 remote control. To adjustthe speaker settings, first press the Devices Button4on the TC 30, and then press the ScreenButton 6at the top of the left vertical row, to theright of the AVR image on the remote’s screen.When the images in the LCD change, press theScreen Button 6next to the box with the wordSPEAKER.Immediately press the ‹/›Navigation Buttons D©until the desiredspeaker position’s name appears in the LowerDisplay Line D, and in the semi-OSD message,if the video in use is a 480i source.Within five seconds of stopping at the desired speakerposition, press the OK/Enter Button E. Use the‹/›Navigation Buttons D©to select thedesired setting and then press the OK/Enter ButtonEagain to enter the setting into the system memory.Delay SettingsDue to the different distances between the listeningposition and each speaker position, the amount oftime it takes for sound to reach your ears from eachchannel is different. You may compensate for this dif-ference through the use of the delay settings to adjustthe timing for the speaker placement and acousticconditions in your listening room or home theater.In most cases, the settings established by EzSet/EQIIare accurate to within one foot, but the placement of the microphone and other factors may influence the setting. Should you wish to manually adjust thechannel delay times, follow the instructions shownbelow. Whenever adjustments to the delay settings aremade remember that the distance settings need notbe accurate to the inch, as the system is designed toaccommodate a typical listening area rather than theprecise measurement from the speakers to a specific“sweet spot” position.SYSTEM CONFIGURATIONSYSTEM CONFIGURATIONSYSTEM CONFIGURATION 35SYSTEM CONFIGURATION 35AVR 745 OM 5/15/06 5:00 PM Page 35
In addition to providing delaying adjustments for eachindividual speaker position, the AVR 745 allows you toadjust the delay for the combined output of all speak-ers as a group. This feature is called A/V Sync Delay;it allows you to compensate for delays to the videoimage that may be caused by the processing in prod-ucts such as digital video displays, video scalers, digitalcable or satellite systems, or personal video recorders.With proper adjustment of the setting for A/V SyncDelay, you can eliminate the loss of lip sync that maybe caused by digital video applications.To view or change the current delay settings, makesure the EZSET/EQ MAIN menu (Figure 12)is on the screen. Press the ⁄/¤NavigationButtons D©to move the cursor to DELAYADJUST and then press the OK/Enter ButtonEon the TC 30 or the Set Buttonœon theZR 10. The DELAY ADJUST menu (Figure29) will appear on the screen.Figure 29Once the DELAY ADJUST menu is on yourscreen, note that the default for distance settings is infeet. If your measurements are in feet, proceed to thenext step; if your measurements are made in meters,press the ¤Navigation Buttons D©until theon-screen cursor is at the UNIT line on the menu.Then, press the ‹/›Navigation Buttons D©so that METER is highlighted. When the change in measurement units is made, press the ⁄/¤Navigation Buttons D©to return the cursor to the FL position.If you wish to reset all delay settings to the factorydefaults, as shown in Figure 29, press the ⁄/¤Navigation Buttons D©until the cursor is point-ing to the DELAY RESET line. Next, press the‹/›Navigation Buttons D©so that ON ishighlighted in reverse video.The settings will reset, andyou may now continue to make any needed changesfollowing the instructions below. Once you make thefirst change to the default settings, the DELAYRESET line will return to OFF, indicating that the factory defaults are no longer in effect.To change a setting, first make certain that the on-screen cursor is pointing to FL,and press the ‹/›Navigation Buttons D©until the distance fromthe center speaker to the preferred listening position isentered. Next, press the ‹/›Navigation ButtonsD©to move the cursor to the next line and usethe ‹/›Navigation Buttons D©again toenter the distance from the main listening position tothe center speaker. Repeat the procedure for all activespeaker positions, first using the ⁄/¤NavigationButtons D©to change to the next position;then use the ‹/›Navigation Buttons D©tochange the setting. Note that only the speaker posi-tions that have been set to LARGE or SMALLin the SPEAKER SIZE menu, as shown onpage 34, may be adjusted. The appearance of threedashes next to a speaker position in place of a dis-tance setting indicates that you have not configured an active speaker for that location.If you have already run EzSet/EQII, return to the set-tings established by the automated system by pressingthe ⁄/¤Navigation Buttons D©until thecursor is pointing to the EZSET SETTINGSline. Next, press the ‹/›Navigation ButtonsD©so that ON is highlighted in reverse video.The settings will be resent to the values calculated by EzSet/EQII, and the menu will be locked so that the settings may not be changed. To go back into the menu and make any manual changes to one ormore channels, you must first return the cursor to theEZSET SETTINGSline and press the ‹/›Navigation Buttons D©so that OFF is high-lighted in reverse video. This will unlock the menu toallow changes.When the delay time for all speaker positions hasbeen set, you may return to the manual setup bypressing the ⁄/¤Navigation Buttons D©until the cursor points to BACK TO MANUALSETUP and then pressing the OK/Enter ButtonEon the TC 30 or the Set Buttonœ. However,if you have a digital video source or a digital video dis-play that causes lack of lip sync, you may use the A/Vsync adjust feature to delay the audio signal as it issent to all channels (as opposed to the individual set-tings) so that the picture and sound are brought backtogether. We recommend that this adjustment bemade using the direct-access controls on the remote,as shown below.That enables you to see the imagewhile making the adjustment; however, you may alsoadjust it here using the menu system.To adjust the A/V sync delay, press the ⁄/¤NavigationButtonsD©so that the cursor is pointing to theA/V SYNC DELAY line in the menu and thenpress the ‹/›Navigation Buttons D©todelay the sound until it matches the on-screen video.The delay settings may also be adjusted directly andwithout going into the OSD menu system at any timeusing the TC 30 remote control and while viewing anon-screen image. This is particularly helpful in the caseof the A/V sync delay, since it is important to be ableto view the impact of the A/V sync delay adjustmentwith on-screen images.To adjust the delay settings, first try to have a programon the video display that has close-ups and dialogue.If you feel that the audio is ahead of the picture, lookclosely at the actors’ lips when they stop speaking,and notice whether their lips move for a short durationafter the dialogue has stopped. When using the delayadjustments, change the setting so that the movementof the actors’ lips is in sync with the sound, so that thesound stops when their lips stop. This is a good wayto get the image and sound locked together.The controls for A/V sync delay are activated by firstpressing the Devices Button 4on the TC 30, andthen pressing the Screen Button 6at the top ofthe left vertical row, to the right of the AVR image inthe remote’s screen. When the images in the LCDchange, press the Screen Button 6to the left ofthe box with the word DELAY.Within five seconds, when the A/V SYNCDELAY message appears in the Lower DisplayLine D, press the OK/Enter Button Eand thenuse the ‹/›Navigation Buttons D©to bringthe image and sound into sync. When you have com-pleted the adjustments, press the OK/Enter ButtonEagain to enter the setting into the system memory.When a 480i image is being viewed, you will see theA/V sync time message appear as a semi-OSD on-screen message, as well as in the front-panel display.Semi-OSD messages are not available when 480p orhigher resolution video is in use.To change the delay setting for an individual speakersetting directly, rather than the A/V sync “group delay,”follow these same instructions, but when the A/VSYNC DELAY message appears, press the ‹/›Navigation Buttons D©until the desiredspeaker position name appears, and then press theOK/Enter Button Eto start the selection, the ‹/›Navigation Buttons Dto change the delaysettings, and finally the OK/Enter Button Eto store the setting.Note that the A/V sync delay setting is unique to each video input source, so you may enter a differentsetting to compensate for the differences with anyproduct attached to the different inputs.When all changes to the Delay settings have beenmade, press the ⁄/¤Navigation Buttons D©until the cursor is on the BACK TO MANUALSETUP menu and then press the OK/EnterButton Eon the TC 30 or the Set Buttonœso that you may make any other adjustments to thesystem parameters.

Output Level AdjustmentOutput level adjustment is a key part of the configura-tion of any surround sound product. It is particularlyimportant for a digital receiver such as the AVR 745,as correct outputs ensure that you hear soundtrackswith the proper directionality and intensity.In most cases, you will not need to make any adjustments to the output level, as the settings made by running EzSet/EQII are as accurate as thosemade manually. However, you are able to use theCHANNEL ADJUST menu to trim the settingsto suit your personal preferences or to configure thesystem so that the output settings are different fromone input source to another. The ability to make indi-vidual output level adjustments on a per-input basis isuseful for listeners who may prefer different settingsfor the subwoofer or an individual channel group (suchas the front speakers) when playing musical selections via the CD input, as opposed to the movie sound-tracks more frequently used with the DVD input. Thismenu also allows you to adjust the output levels using external sources such as a test disc or other programmaterial that you use as a standard, rather than thesystem’s test tone.IMPORTANT NOTE: Listeners are often confusedabout the operation of the surround channels. Whilesome assume that sound should always be comingfrom each speaker,most of the time there will be littleor no sound in the surround channels. This is becausethey are only used when a movie director or soundmixer specifically places sound there to create ambi-ence, a special effect or to continue action from thefront of the room to the rear. When the output levelsare properly set, it is normal for surround speakers to operate only occasionally. Artificially increasing thevolume to the rear speakers may destroy the illusionof an enveloping sound field, which duplicates theway you hear sound in a movie theater or concert hall.Before beginning the output level adjustment process,make certain that all speaker connections have beenproperly made.The system volume should be set to thelevel that you will use during a typical listening session.We recommend that EzSet/EQII be used when the AVRis first installed, to establish the initial level settings.To view or change the current Channel Output set-tings, make certain that the EZSET/EQ MAINmenu (Figure 12) is on the screen. Press the ⁄/¤Navigation Buttons D©to move the cursornext to CHANNEL ADJUST and then pressthe OK/Enter Button Eon the TC 30 or the Set Buttonœon the ZR 10 remote control. TheCHANNEL ADJUST menu (Figure 30) willappear on the screen.Figure 30To provide the maximum flexibility, channel output leveladjustments may be made either with or without theinternal test tone, and when the tone is in use, it maybe programmed to automatically circulate among theactive channels or to only move from one channel tothe next on your command. When the CHANNELADJUST menu appears, we recommend that youfirst run the test tone once in the automatic mode toverify that the speakers have been properly connected.To do this, press the ⁄/¤Navigation ButtonsD©again until the cursor is on the TESTTONE line and then press the ‹/›NavigationButtons D©until AUTO is in highlightedvideo. The test tone will then circulate among all channels for five seconds at each position.As the test tone circulates, the cursor will flash as itmoves to each position, to indicate where the toneshould be coming from. If the tone is heard from adifferent speaker than the one indicated on the menuscreen, turn the AVR 745 off using the Main PowerSwitch Aand check the speaker wiring or connec-tions to external power amplifiers to make certain thateach speaker is connected to the correct output ter-minal. When you have verified that all speakers areconnected properly, turn the AVR 745 on and returnto this menu to resume the channel adjustment proce-dure. If any speaker connections were changed, wealso recommend that you rerun EzSet/EQII beforemaking any manual calibration adjustments.After checking for speaker placement, let the testnoise circulate again, and listen to see which channelssound louder than the others. Using the front leftspeaker as a reference,press the ‹/›NavigationButtons D©on the remote to bring all speakersto the same volume level. The test noise circulation willpause on the channel being adjusted to give you timeto make the adjustment. When you release the button,the circulation will resume after five seconds.Continue to adjust the individual channels until the volume level sounds the same from each speaker.Adjustments should be made with the ‹/›NavigationButtons D©on the remote only, NOT the mainvolume controls. If you are using a sound-pressurelevel (SPL) meter for precise level adjustment,set the volume so that the meter reads 75dB,C-Weighting Slow.When all channels have an equal volume level, theadjustment is complete. To exit this menu, press the⁄/¤Navigation Buttons D©until the cursoris next to the BACK TO MANUAL SETUPline, and then press the OK/Enter Button Eon theTC 30 or the Set Buttonœto return to theMANUAL SETUP.In addition to having the test tone circulate automati-cally, you may also turn the test tone on, but advanceit from one channel to the next manually. This allowsyou to make calibration adjustments, but to have morecontrol over the way the test tone is moved amongthe channels.To change the tone manually, first make certain thatthe CHANNEL ADJUST menu is on thescreen, following the instructions shown above, andthen press the ⁄/¤Navigation Buttons D©until the cursor is on the TEST TONE line.Next, press the ‹/›Navigation Button ountilMAN is highlighted. This will start the test tone fromthe front left speaker position but, rather than circulat-ing to the next channel every five seconds as is thecase in the automatic mode, you must press the⁄/¤Navigation Buttons D©to change thechannel the test tone is being sent to. When you havecirculated through all channels, the test tone will stop,but you may restart it by returning to the TESTTONE line and activating manual sequencing.The final option for tone adjustment using the menusystem is to not use the internal test tone at all. Simplyuse the ⁄/¤Navigation Buttons D©tochange the channel and then use the ⁄/¤Navigation Buttons D©to change the outputlevel. When making channel output adjustments with-out the internal test tone, we strongly recommend thatyou use a test disc in the “repeat” mode on your DVDor CD player so that the signal being used is constantthroughout the adjustment process.The output level settings may also be adjusted directly(without going into the OSD menu system) at any time,using the TC 30 remote control.To adjust the speakersettings, first press the Devices Button 4on theTC 30,and then press the Screen Button 6at thetop of the left vertical row, to the left of the AVRimage on the remote’s screen. When the images inthe LCD change, press the Screen Button 6nextto the box with the word TEST.As soon as the button is pressed, the test tone willbegin to circulate, as indicated earlier. The correctchannel from which the test noise should be heard willbe shown in the lower third of the video screen and inthe Lower Display Line $. While the test noise iscirculating, the proper channel position will also beindicated in the Speaker/Channel Input Indicators@by a blinking letter within the correct channel. * CHANNEL ADJUST * FL : 0dB SBR : 0dB CEN : 0dB SBL : 0dB FR : 0dB SL : 0dB SR : 0dB SW1 : 0dB SW2 : 0dB TEST TONE: AUTO OFF MAN LEVEL RESET: OFF ON CH ADJUST: GLOBAL EZSET SETTINGS: OFF ON BACK TO MANUAL SETUP →→SYSTEM CONFIGURATIONSYSTEM CONFIGURATIONSYSTEM CONFIGURATION 37SYSTEM CONFIGURATION 37AVR 745 OM 5/15/06 5:00 PM Page 37
To adjust the output level, press the ⁄/¤NavigationButtons D©until the desired level is shown inthe display or on the screen. Once the buttons arereleased, the test noise will begin to circulate again infive seconds. When all channels have the same outputlevel, press the Screen Button 6next to TESTagain to complete the process.NOTE: Output level adjustment with the test tone isnot available in the Surround Off modes.In addition to the controls for selecting channels andthe test tone operation, the settings on this menu also allow you to reset the level settings to either the factory default of 0dB or the settings that wereentered by running EzSet/EQII.To reset all channel levels to 0dB, press ⁄/¤Navigation Buttons D©so that the cursor ispointing to the LEVEL RESET line and thenpress the ⁄/¤Navigation Buttons D©onceso that ON appears in highlighted video.To return to the settings established by EzSet/EQII,even if you have made manual changes to the outputtrims using the steps shown above, press ⁄/¤Navigation Buttons D©so that the cursor ispointing to the EZSET SETTINGS line andthen press the ‹/›Navigation Buttons D©once so that ON appears in highlighted video.Remember that after turning the EzSet/EQII settingsback on, you must return to this menu line andchange the setting to OFF if you wish to make anymanual trim adjustments.The final setting in this menu enables you to have theoutput levels remain the same for all inputs or to beadjusted differently for each (or any) input. While mostlisteners prefer to keep the same output levels for allsources, you may wish to raise or lower some channels,particularly the subwoofer output, for a specific source(such as a CD) that is primarily used for music playback.To enter individual settings for a specific channel, firstmake sure that you have run EzSet/EQII and/or madeany desired manual trim adjustments, to set a baselinefor all channels. Next, press the ⁄/¤NavigationButtons D©to move the cursor to the CHADJUST line and then press the ‹/›NavigationButtons D©so that INDEPENDENTappears. After that is done, press the Menu ButtonAor the OSD Button∫to exit the menu sys-tem and then select the input for which you wish toenter different level settings by using either the InputSource Selector 7on the front panel or the but-tons on the TC 30 or ZR10 remote that are used toselect an input source dWhç∂.Next,return to the CHANNEL ADJUST submenuusing the steps outlined above.When all changes to the Channel Output levels havebeen made,press the ⁄/¤Navigation ButtonsD©until the cursor is on the BACK TOMANUAL SETUP menu and then press theOK/Enter Button Eon the TC 30 or the SetButtonœso that you may make any other adjust-ments to the system parameters. If the changes justmade complete the manual adjustments needed,press the Menu Button Aor the OSD Button∫to exit the menu system and resume normalsystem operation.Additional Input AdjustmentsAfter one input has been configured, go back to theIN/OUT SETUP line on the MASTERMENU (Figure 1) and enter the settings for eachinput that you will use. In most cases, only the videoinput, digital input and surround mode will be differentfrom one input to the next, while the speaker type,crossover frequency, Night mode and output level settings will usually be the same and may be quicklyentered by entering the same data used for the original input.Once the settings outlined on the previous pages havebeen made, the AVR 745 is ready for operation. Whilethere are some additional settings to be made, theseare best done after you have had an opportunity to lis-ten to a variety of sources and different kinds of pro-gram material. These advanced settings are describedon pages 49 and 50 of this manual. In addition, anyof the settings made in the initial configuration of theunit may be changed at any time.

To listen through theheadphones using the Dolby Headphone mode,simply press the buttons on the remote or frontpanel as shown below for changing a Dolby mode.DOLBY H: DH will appear in the LowerDisplay Line when the Dolby Headphone mode is in use.Surround Mode SelectionOne of the most important features of the AVR 745 is its ability to reproduce a full multichannel surroundsound field from digital sources, analog matrix surround-encoded programs and standard stereo programs.Selection of a surround mode is based on personaltaste, as well as the type of program source materialbeing used. For example, motion pictures or TV pro-grams bearing the logo of one of the major surround-encoding processes, such as Dolby Surround or DTSStereo may be played in either the Dolby Digital,Dolby Pro Logic II Cinema, DTS Neo:6 Cinema, orLogic 7 Cinema surround modes, depending on thesource material.NOTE: Once a program has been encoded with matrixsurround information, it retains the surround informationas long as the program is broadcast in stereo. Thus,movies with surround sound may be decoded via any of the analog surround modes such as Pro Logic IICinema, Logic 7 Cinema or DTS Neo:6 Cinema, whenthey are broadcast via conventional TV stations,cable,pay-TV and satellite transmission. In addition, a growingnumber of made-for-television programs,sports broad-casts, radio dramas and music CDs are also producedin surround sound. You may view a list of these pro-grams at the Dolby Laboratories Web site atwww.dolby.com.Even when a program is not listed as carrying inten-tional surround information, you may find that the DolbyPro Logic II, Dolby Pro Logic IIx, Logic 7 or DTS Neo:6,and the Hall or Theater modes often deliver envelopingsurround presentations through the use of the naturalinformation present in all stereo recordings.Surround modes may be changed at any time byusing either the front panel or remote control. Toselect a new surround mode from the front panel, firstpress the Surround Mode Group Selector Button2until the desired major surround mode group suchas Dolby, DTS or Logic 7 is selected. Next, press theSurround Mode Selector Button 3to choose thespecific individual surround mode.To select a surround mode using the TC 30 remote,first press the Devices Button 4, followed by theScreen Button 6at the top of the row of buttonson the left side of the TC 30, to the left of the A/Vreceiver image on the LCD screen.

It provides up to five separate main audio channels and a special dedicated low-frequency effects channel.Dolby Digital EX Available when the receiver is configured for 6.1/7.1-channel operation, Dolby Digital EX is the latest version of Dolby Digital. When used with movies or other programs that have special encoding, Dolby Digital EX reproduces specially encoded soundtracks so that a full 6.1/7.1 sound field is available. Even if a source does not contain specific EX encoding, the special algorithms may be used to derive a 6.1/7.1 output.DTS 5.1 When the speaker configuration is set for 5.1-channel operation, the DTS 5.1 mode is available when DVD, audio-only music or laser discs encoded with DTS data are played. DTS 5.1 provides up to five separate main audio channels and a special dedicated low-frequency channel.DTS-ES 6.1 Matrix When the speaker configuration is set for 6.1/7.1 operation, playback of a DTS-encoded program source will automatically trigger the selection DTS-ES 6.1 Discrete of one of the two DTS-ES modes. Newer discs with special DTS-ES discrete encoding will be decoded to provide six discrete, full-bandwidth channels plus a separate low-frequency channel. All other DTS discs will be decoded using the DTS-ES Matrix mode, which creates a 6.1-channel sound field from the original 5.1-channel soundtrack.Dolby Pro Logic II Dolby Pro Logic II decodes full-range, discrete, left, center right, right surround and left surround channels from either matrix surround-encoded Movie programs and conventional stereo sources when an analog input is in use. The Dolby Pro Logic II Movie mode is optimized for movie soundtracks,Music while the Pro Logic II Music mode should be used with musical selections. The Pro Logic II Game mode is designed to enhance the soundtrack Game of video games from either dedicated consoles or computers.The Pro Logic mode re-creates original Pro Logic processing for those who Pro Logic prefer that presentation.Dolby Pro Logic IIx Dolby Pro Logic IIx is the latest extension of Dolby Laboratory’s benchmark matrix surround technology which creates a discrete 7.1 sound field from Movie matrix surround or two-channel stereo sources when your system is configured for surround back speakers. Movie, Music and Game versions are Music available that customize the processing to the type of source in use. These modes may also be used to create 7.1 sound fields from 5.1 digital Game soundtracks.Logic 7 Cinema Exclusive to Harman Kardon for A/V receivers, Logic 7 is an advanced mode that extracts the maximum surround information from either Logic 7 Music surround-encoded programs or conventional stereo material. When your system has been configured for use with Surround Back speakers (see page 41), you may choose between either 7.1 or 5.1 versions of the Logic 7 modes, while only the 5.1 versions are available when there are no Surround Back speakers. The Logic 7 C (or Cinema) mode should be used with any source that contains Dolby Surround or similar matrix encoding. Logic 7 C delivers increased center channel intelligibility, and more accurate placement of sounds with fades and pans. The Logic 7 M (or Music) mode enhances the listening experience by presenting a wider front soundstage and greater rear ambience. Both Logic 7modes also direct low-frequency information to the subwoofer (if installed and configured) to deliver maximum bass impact. Logic 7 adds additional bass enhancement that circulates low frequencies in the 40Hz to 120Hz range to the front and surround speakers to deliver a less localized soundstage that seems broader and wider than when the subwoofer is the sole source of bass energy. Logic 7/7 may also be used to add surround back channels to many 5.1 digital soundtracks.DTS Neo:6 Cinema These two modes are available when any analog source is playing to create a three-channel, five-channel or six-channel surround presentation from DTS Neo:6 Music conventional Matrix-encoded and traditional Stereo sources. Select the Cinema version of Neo:6 when a program with any type of analog Matrix surround encoding is present. Select the Music version of Neo:6 for optimal processing when a nonencoded, two-channel stereo program is being played.DTS 96/24 DTS 96/24 is available on specially encoded (and labeled) optical discs that offer five channels of audio with a 96kHz sampling rate that delivers greatly improved audio performance.When a DTS 96/24 disc is in use and the player is connected with a digital link, this mode is selected automatically.Theater The Theater mode creates a sound field that resembles the acoustic feeling of a standard live-performance theater.Hall 1, Hall 2 The two Hall modes create sound fields that resemble a small- (Hall 1) or medium-sized (Hall 2) concert hall.Dolby Virtual Speaker Dolby Virtual Speaker technology uses a next-generation advanced algorithm to reproduce the dynamics and surround sound effects of a precisely Reference placed 5.1-channel speaker system using only front left and right speakers. In the Reference mode, the apparent width of the sound across the front Wide image is defined by the distance between the two speakers. The Wide mode provides a wider, more spacious front image when the two speakers are close together. Depending on the number of speakers available in your system, a variety of different sound field options are available for both the Reference and Wide modes.5-Channel Stereo This mode takes advantage of multiple speakers to place a stereo signal at both the front and back of a room. Depending on whether the AVR7-Channel Stereo has been configured for either 5.1 or 6.1/7.1 operation, one of these modes, but not both, is available at any time. Ideal for playing music in situations such as a party, it places the same signal at the front-left and surround-left, and front-right and surround-right speakers.The center channel is fed a summed mono mix of the in-phase material of the left and right channels.Surround This mode turns off all surround processing and presents the pure left- and right-channel presentation of two-channel stereo programs.Off (Stereo)Dolby Headphone (DH) Dolby Headphone enables ordinary stereo headphones to portray the sound of a five-speaker surround-playback system.For additional information on the specifics of surround modes and processing, information about Dolby modes may be found at www.dolby.com.

The firstpress of a button will show the current mode from thatgroup if it is already in use, or the first available modeif you are currently using another mode. To cyclethrough the available modes in that group, press thebutton again until the desired mode appears in theLower Display Line $, the on-screen display andthe front-panel Surround Mode Indicators %.The Dolby Digital, Dolby Digital EX, DTS 5.1, DTS-ESMatrix and DTS-ES Discrete modes may only beselected when a digital input is in use. In addition,when a digital source is present, the AVR 745 willautomatically select and switch to the correct mode,regardless of the mode that has been previouslyselected. For more information on selecting digitalsources, see the Digital Audio Playback section below.When the 6-channel/8-channel direct inputs are inuse, there is no surround processing, as these inputstake the analog output signals from an external sourcedevice and carry them straight through to the volumecontrol without any further digital processing.To listen to a program in traditional two-channel stereo,using the front left and front right speakers only (plus the subwoofers, if installed and configured),first follow the instructions shown above so that theAVR: Surround Menu page of theTC 30 remote is on the LCD Screen 7, and thenpress the Screen Button 6to the right of theStereo option until SURROUNDOFF appears in the Lower Display Line $. From the front panel,press the Surround Mode Group Selector 2until the Stereomodes appear in the on-screen displayand Lower Display Line $. Next, press theSurround Mode Selector Button 3untilSURROUND OFF appears in the on-screen display and Lower Display Line $.Digital Audio PlaybackDigital audio is a major advancement over older analogsurround processing systems. It delivers up to six dis-crete channels,and each channel reproduces a full-fre-quency range (20Hz to 20kHz) and offers dramaticallyimproved dynamic range and significant improvements tosignal-to-noise ratios. In addition, digital systems have thecapability to deliver an additional channel that is specifi-cally devoted to low-frequency information. This is the“.1” channel referred to when you see these systemsdescribed as “5.1,” “6.1” or “7.1.” The bass channel isseparate from the other channels, but since it is inten-tionally bandwidth-limited, sound designers have given it that unique designation. When a digital soundtrack is playing, the number of channels available will vary according to the way in which the program wasrecorded. Although most movies recorded with digitalsound have 5.1 soundtracks, some have 6.1 or 7.1sound, while others retain the original two-channel oreven monaural sound. When the program source is abroadcast, cable or satellite delivered digital program,only one type of soundtrack may be delivered at atime, while optical sources such as DVD may providemore than one audio option. In either case, the deci-sion of what type of sound track and how many chan-nels to offer is up to the program’s producer. With theAVR 745 you are able to not only play back the origi-nal compatible digital format, but using the processingpower of the Texas Instruments DSP processor, it ispossible to decode the basic digital track for 2.0 or5.1 sound and then select an additional “post-pro-cessing” mode to deliver additional channels.Dolby DigitalDolby Digital is the default format for DVD discs andfor the (ATSC) high-definition system used in theUnited States and Canada. It is also used by the digitalsatellite program services and is available on mostdigital cable set-top boxes. When the AVR 745 is con-nected to a blue-laser-based high-definition opticaldisc player via an HDMI, coaxial or optical digital con-nection, the soundtrack from the player is also avail-able in the standard Dolby Digital format so that it maybe decoded by the AVR.An optional, external RF demodulator is required touse the AVR 745 to listen to the Dolby Digital sound-tracks available on laser discs. Connect the RF outputof the LD player to the demodulator and then connectthe digital output of the demodulator to the Opticalor Coaxial Inputs KMde of the AVR 745. Ademodulator is not required for use with high-definitionoptical disc or DVD players, or with DTS-encodedlaser discs.In order to provide maximum playback compatibilitywith DVDs, the AVR 745 receiver will always defaultfirst to the playback mode embedded in a disc’s digital“flag” information. For Dolby Digital discs, the followingplayback modes are initially selected after the AVRlocks to the incoming digital audio data stream toidentify the selected:• When a Dolby Digital 5.1 data stream is detected,the choice of which surround mode is activated isdetermined by the setting on the DEFAULTSURR line of the SURROUND CONFIGmenu (Figure 19), as shown on page 28.• When a disc with the Dolby Digital EX format flag isplayed, your system will automatically switch to theEX mode when seven main-channel speakers areavailable.• When a disc with 2.0 Dolby Digital data is detected,the default mode is Dolby Digital with Pro Logic IIpostprocessing when you have a 5.1 speaker sys-tem, or Dolby Digital with Pro Logic IIx postprocess-ing when you have a 7.1 speaker system.• Depending on the number of speaker channelsavailable in your system, once the AVR locks to the digital signal, you may select any surroundmode or postprocessing option that is available,based on the incoming data stream’s possiblerestrictions and the number of speakers in your system. For example, when a 5.1 or 2.0 audiostream is in use, you may select alternate post-processing such as Logic 7/7-channel Movie Modepostprocessing to create the rear surrounds in 7.1speaker systems.DTSDTS is another digital audio system that is capable of delivering 5.1 or 6.1 discrete or matrix sound fieldreproduction. Although both DTS and Dolby Digital aredigital, they use different methods of encoding the sig-nals, and thus they require different decoding circuitsto convert the digital signals back to analog.DTS-encoded soundtracks are available on select DVDand LD discs, as well as on special audio-only DTSdiscs. You may use any LD or CD player equippedwith a digital output to play DTS-encoded discs withthe AVR 745. All that is required is to connect theplayer’s output to either an Optical or Coaxial Inputon the rear panel de or front panel KM.In order to listen to DVDs encoded with DTS sound-tracks, the DVD player must be compatible with theDTS signal, which is indicated by a DTS logo on theplayer’s front panel. Early DVD players may not beable to play DTS-encoded DVDs. If you are in doubtas to the capability of your DVD player to handle DTSdiscs, consult the player’s owner’s manual.When the AVR 745 is connected to a blue-laser-based high-definition optical disc player via an HDMI,coaxial or optical digital connection, the soundtrackfrom the player is also available in the standard DTSformat so that it may be decoded by the AVR.NOTE:• Some DVD players have a default setting that doesnot pass through the DTS signal. Before playingDVDs with a DTS soundtrack, make certain that the settings in your DVD player have been properlyadjustedso that DTS audio is passed through.Consult the owner’s manual for your DVD player formore information on making these settings.• When selecting surround modes, any mode wherethe setting in its mode group (Dolby, DTS, Logic 7,PCM, etc.) has been set to OFF in one of theSURROUND CONFIG menus will notappear. You may change the settings in this list atany time by following the instructions on page 28.AVR 745 OM 5/15/06 5:00 PM Page 42
OPERATIONOPERATION 43OPERATION 43Selecting a Digital SourceTo utilize either digital mode, you must have properlyconnected a digital source to the AVR 745. Connectthe digital outputs from DVD players, HDTV receivers,satellite systems or CD players to the Optical orCoaxial Inputs KMde. In order to provide a backup signal and a source for analog stereo recording,the analog outputs provided on digital source equipmentshould also be connected to their appropriate inputs onthe AVR 745 rear panel (e.g., connect the analog stereoaudio output from a DVD to the DVD Audio Inputson the rear panel when you connect the source’s digital outputs).If you have not already configured an input for a digital source using the on-screen menus, as shown on page 22, first select the input using the remote orfront-panel controls, as outlined in this manual. Next,press the Devices Button 4, followed by theScreen Button 6at the top of the row of buttonson the left side of the TC 30, to the left of the A/Vreceiver image on the LCD screen. After the list ofoptions displayed in the LCD Screen 7changes,press the Screen Button 6to the left of SetupMenu. After the options change, press the ScreenButton 6to the right of Digital Inputand then press the ‹/›Navigation Buttons Donthe TC 30 remote or the ‹/›Navigation ButtonHon the front panel to choose any of the OPTI-CAL or COAXIALinputs, as they appear in theUpper Display Line #or on-screen display. Whenthe digital source is playing, the AVR 745 will automat-ically detect which type of digital data stream is beingdecoded and display that information in the UpperDisplay Line #.When both a digital and an analog connection aremade between a source device and the AVR, the digi-tal input is the default. If the digital stream is not pres-ent or is interrupted, the unit will automatically switchover to the analog inputs for the selected source.If you wish to disable the auto-polling feature, you may do so by following the instructions shown for theIN/OUT SETUP menu (Figure 2), as shownon page 22.Digital Bitstream and Surround Mode IndicationsWhen a digital source is playing, the AVR 745 sensesthe type of bitstream data that is present, and auto-matically selects the proper surround mode. For exam-ple, DTS bitstreams will cause the unit to switch toDTS decoding, and Dolby Digital bitstreams will enableDolby Digital decoding. When the unit senses PCMdata from CDs or LDs, you may select any of the stan-dard Dolby or DTS surround modes or Logic 7. Sincethe range of available surround modes is dependenton the type of digital data that is present, the AVR 745shows you what type of signal is present to help youunderstand the choice of modes.When a digital source is first detected, the AVR 745will display a message to indicate the type of bitstreambeing received. It will remain in the Lower DisplayLine $for about 5 seconds before that portion of thedisplay returns to the normal surround mode indication.For Dolby Digital and DTS sources, a numerical indica-tion (such as 3/2/2.1) will appear, showing thenumber of channels present in the data.The first number in the display message indicates howmany discrete front-channel signals are present.• A “3” tells you that separate front left, center andfront right signals are available. This will be displayedfor Dolby Digital 5.1, Dolby Digital EX and DTS 5.1or DTS-EX programs.• A “2” tells you that separate front left and right sig-nals are available, but there is no discrete centerchannel signal. This will be displayed for DolbyDigital bitstreams that have stereo program material.• A “1” tells you that there is only a mono channelavailable in the Dolby Digital bitstream.The middle number in the display message indicateshow many discrete surround channel signals are present.• A “3” tells you that separate, discrete left surround,center surround and right surround signals are pres-ent. This is available only on discs with DTS-ES digital audio.• A “2” tells you that separate surround left and rightsignals are available. This will be displayed for DolbyDigital 5.1 and DTS 5.1 programs.• A “1” tells you that there is only a single, surround-encoded surround channel. This will appear forDolby Digital bitstreams that have matrix encoding.• A “0” indicates that there is no surround channelinformation. This will be displayed for two-channelstereo programs.The last number indicates whether there is a discretelow-frequency effects (LFE) channel. This is the “.1” inthe common abbreviation of “5.1” sound and it is aspecial channel that contains only bass frequencies.• A “.1” tells you that an LFE channel is present. Thiswill be displayed for Dolby Digital 5.1 and DTS 5.1programs, as available.• A “0” indicates that there is no LFE channel infor-mation available. However, even when there is nodedicated LFE channel, low-frequency sound will bepresent at the subwoofer output when the speakerconfiguration is set to show the presence of a subwoofer.• The information on the right side of the display willtell you whether the digital audio data contains aspecial flag signal that will automatically activate theappropriate 6.1 or 7.1 mode. This will be shown as EX-ON or EX-OFF for Dolby Digital bitstreams andES-ON or ES-OFF for DTS bitstreams.When a 2.0 or 5.1 digital source is playing on a sys-tem configured for 5.1 operation, you may use DolbyDigital EX, DTS-ES, Logic 7/7 or Dolby Pro Logic IIxto add rear channels for full 7.1 sound fields. Note,however, that the availability of specific modes forpostprocessing is dependent on the format of theincoming source material. While some combinations(e.g., a Dolby Digital or DTS 5.1 source with Logic 7/7 or Dolby Pro Logic IIx postprocessing) are allowable,others (e.g., a Dolby Digital 5.1 source with DTSNeo:6) are not. If you wish to add surround backchannels to a 2.0 or 5.1 source, we recommend thatyou experiment with the various options to see whichmay be available and which are best suited to yourtaste and listening environment.It is always a good idea to check the readout for thechannel data to make certain that it matches the audiologo information shown on the back of a DVD pack-age. In some cases, you will see an indication for“2/0/0” even when the disc contains a full 5.1, or3/2/.1, signal. When this happens, check the audiooutput settings for your DVD player or the audio menuselections for the specific disc being played to makecertain that the player is sending the correct signal to the AVR.PCM PlaybackPCM is the abbreviation for Pulse Code Modulation,the digital signal format used for standard CD play-back, and other non-Dolby Digital and non-DTS digitalsources such as MiniDisc. When a PCM signal isdetected, the Lower Display Line $will brieflyshow a message with the letters PCM, in addition to areadout of the sampling frequency of the digital signal.In most cases, this will be PCM 44.1kHz orPCM 48kHz, though in the case of speciallymastered, high-resolution audio discs, you will see aPCM 96kHz indication. Note that the samplingrate displayed is that of the incoming digital signal, andnot the upsampled rate that may be applied to PCMsources when Dolby Pro Logic or Pro Logic II pro-cessing is applied, as shown on page 27.During PCM playback, you may select any surroundmode except Dolby Digital or DTS/DTS-ES mode.USB PlaybackThe AVR 745 is among the very few A/V receiverscapable of direct connection to a computer for audioplayback. Once the AVR is connected, audio streamsand playback are possible through your AVR, with allthe power and performance of the high-current amplifi-er,your own speakers, and the enhanced multichannelplayback made possible through the use of Logic 7,Dolby Pro Logic II/IIx or DTS Neo:6 processing.3334353637383940414849464744454243383940413132302829252627282930242322212031373635343332 3137363534333248495051474645444342AVR 745 OM 5/15/06 5:00 PM Page 43
OPERATION44 OPERATIONThe AVR 745’s USB connectivity may be used withPC-compatible computers running either Microsoft®Windows®2000 with Service Pack 4 or higherinstalled, or Windows XP®or Windows XP MediaCenter Edition with Service Pack 1 or higher installed.Connect one of the available USB jacks on your com-puter or a USB hub to the USB Jack Zon the AVRusing a cable with a standard USB plug on one sideand a USB “Mini B” plug on the other side. You mayuse an optional cable available at most electronics andcomputer stores for this purpose, or you may use thecable supplied for use with the TC 30 remote, if it isnot being used to program the remote.In addition, you will need to have a media playerinstalled on the computer. The AVR 745 has beentested for operation with Windows Media Player®Version 8.0 and above, but it is also compatible withmany other popular players such as iTunes®, WinAmp®and Real Player®. In most cases, it is best to alwaysmake certain that you have the latest version of theplayer installed to ensure the best compatibility.When the connection between a computer and theAVR is made for the first time, or if the USB connectionis plugged into a different USB jack on a computerorhub that has not been previously connected to theAVR, you will see a series of pop-up messages fromWindows to indicate that the computer is configuringitself for the new device. Since the AVR provides anumber of different functions, you may see the “FoundNew Hardware” message up to four times, one eachfor “A/V Receiver,” “Compatible Device,” “AudioReceiver” and “Human Interface Device.” When allmessages have appeared and then cleared thescreen, you are almost ready to begin.Before selecting the USB input, first make certain that one of the media players listed above has beenopened on the computer. Then you may select theUSB input in any of the following ways:• To select USB as a source from the front panel,press the Input Source Selector Button 6untilUSB appears as the input name in the UpperDisplay Line Cand in the semi-OSD display,if available. The USB Input Source Indicator Awill also light up on the front panel.• Two options are available for selecting an inputsource using the TC 30 remote.■ Press the Activities Button 3to display the list of preprogrammed activities and thenpress the Screen Button 6to the left ofListen to USB. This will both selectthe USB input and change the remote codes sothat the buttons will control the media player onyour computer.■ To directly select the USB input as a source,first press the Devices Button 4and thenpress the Screen Button 6to the left of AV Receiver. When the next page ofoptions appears in the LCD Screen 7, pressthe Screen Button 6to the left of USB.• To select USB as an input using the ZR 10 remote,press the USB Input Selector∂.When the USB input is selected and the AVR 745 isconnected to a compatible computer with one of themedia players mentioned above open, you may thenuse the TC 30 to start and stop playback, as well asmove to the next track using either the commandsthat appear in the LCD Screen 7in conjunctionwith presses of the Screen Buttons 6,or theTransport Controls A. Activity of the Transportbuttons may vary from one media player to another,but at the very least you will be able to use the Playand Stop buttons. You may also control the mediaplayer on a connected computer using the TransportControlsπon the ZR 10 remote.Once playback is started, the audio from a USBsource is treated the same as any other two-channelaudio source, and you may apply any of the appro-priate surround processing modes. When playing back audio from a computer via the USB connection,the internal speakers in a laptop computer are often muted.Speaker/Channel IndicatorsIn addition to the bitstream indicators, the AVR 745features a set of unique channel-input indicators thattell you how many channels of digital information arebeing received and/or whether the digital signal isinterrupted (Figure 31).Figure 31The letters inside the boxes tell you which channelsare receiving an input signal. Since conventional ana-log audio is only two channels, the “L” and “R” letterswill light with any analog source. When a digital sourceis in use, you will see letters displayed that correspondto the number of channels in the incoming datastream, which may be just the L and R for two-chan-nel PCM or 2.0 Dolby Digital material. When a 5.1signal is being received, the L/C/R/SL/SR indicatorswill light, with the LFE indication also being shownwhen an LFE signal is present. All seven indicators,including the SBL/SBR letters, will light for a 7.1 sig-nal, and a horizontal line is shown to connect theSBL/SBR indicators when a 6.1 source is in use.It is important to note that although Dolby Digital, forexample, is referred to as a “5.1” system, not all DolbyDigital DVDs or programs are encoded for 5.1. Thus,it is sometimes normal for a DVD with a Dolby Digitalsoundtrack to trigger only the “L” and “R” indicators.NOTE: Many DVD discs are recorded with both “5.1”and “2.0” versions of the same soundtrack. Whenplaying a DVD, always be certain to check the type ofmaterial on the disc. Most discs show this informationin the form of a listing or icon on the back of the discjacket. When a disc does offer multiple soundtrackchoices, you may have to make some adjustments toyour DVD player (usually with the “Audio Select” buttonor in a menu screen on the disc) to send a full 5.1feed to the AVR 745. It is also possible for the type of signal feed to change during the course of a DVD’splayback. In some cases, the previews of specialmaterial will only be recorded in 2.0 audio, while themain feature is available in 5.1 audio. The AVR 745will automatically sense changes to the bitstream andchannel count and reflect them in these indicators.The letters used by the Speaker/Channel InputIndicators @will flash to indicate when a bitstreamhas been interrupted. This will happen when a digitalinput source is selected before the playback starts, orwhen a digital source such as a DVD is paused. Theflashing indicators remind you that the playback hasstopped due to the absence of a digital signal and notthrough any fault of the AVR 745. This is normal, andthe digital playback will resume once the playback isstarted again.The boxes around the channel indication letters areused to show which speakers are configured in yoursystem. A small box around the letter indicates that a“Small” speaker has been assigned to that position,while a larger, double box indicates a “Large” speakerassignment.Note that in some cases, such as an analog stereo or2.0 digital sources you will see empty speaker posi-tion boxes, which indicates that the speaker is activeand will receive sound, but that there is no discretesignal for that channel. In other cases you may seeletters with no speaker boxes.This indicates that thereis a discrete signal for that channel, but due to themode in use (e.g., Dolby VS with a 5.1 source) thereis no signal being sent to the channel.Night ModeA special feature of Dolby Digital is the Night mode,which enables specially encoded Dolby Digital inputsources to be played back with full digital intelligibilitywhile reducing the minimum peak level by 1/4 to 1/3.This prevents abruptly loud transitions from disturbingothers, without reducing the impact of the digitalsource. The Night mode is available only when DolbyDigital signals with special data are being played.LFE 1 LFE 2AVR 745 OM 5/15/06 5:00 PM Page 44
OPERATION 45OPERATIONThe Night mode may be engaged at any time when a Dolby Digital source is playing by pressing theDevices Button 4on the TC 30, followed by theScreen Button 6at the top of the row of buttonson the left side of the TC 30, to the left of the AVReceiver image on the LCD screen. After the list of options displayed on the LCD Screen 7changes, press the Page Left/Right Button 8to display the next page of options, and press theScreen Button 6to the left of the word Night.Each press of the button will change the Night modesetting, as shown in the lower third of the on-screendisplay (except when 720p or 1080i sources are inuse). To turn the Night mode off, press the button asdescribed until D-RANGE OFF is shown.The Night mode may also be selected to always be onat either level of compression using the options in theDOLBY SURROUND menu. See page 29 forinformation on using the menus to set this option.IMPORTANT NOTES ON DIGITAL PLAYBACK:• When playing DVDs, please note that even when youhave selected a specific digital audio format for play-back, an individual disc may change formats or thenumber of available channels during playback. Forexample, even if you select a DTS mode for the movie,you may see Dolby Digital in use when the trailers,menus or copyright warnings are playing. This is not afault with either the AVR or your DVD player, as bothare responding to the way the disc was created.• When viewing digital television signals,note that thenumber of audio channels available may vary duringthe course of a program, depending on the content.For example, while a sports event may have 5.1sound, the commercials or local station content maybe in 2.0. In addition, not all local stations are currentlyequipped for carrying the 5.1 digital audio signals. Thismay mean that even though the actual program isproduced with 5.1, it may be transmitted in a 2.0configuration in some areas. Your AVR will automaticallychange to react to the proper type of audio stream if itis changed by the broadcast station.• Although the AVR 745 will decode virtually all currentDVD movies, CDs and HDTV sources, it is possiblethat some future digital sources may not be compati-ble with the AVR 745.• Not all digitally encoded programs contain full 5.1-or 6.1-channel audio. Consult the program guidethat accompanies the DVD or laser disc to deter-mine which type of audio has been recorded on thedisc. The AVR 745 will automatically sense the typeof digital surround encoding used and adjust toaccommodate it.• When a digital source is playing, you may not beable to select some of the analog surround modessuch as Dolby Pro Logic II, Dolby Pro Logic IIx,Stereo, Hall, Theater or Logic 7.• When a Dolby Digital or DTS source is playing,it is not possible to make an analog recording usingthe Tape Outputs aand Video 1 Audio Outputsg. However, the digital signals will be passedthrough to the Digital Audio Outputs abM.UUssiinngg The AVR 745 is equipped for use with Harman Kardon’soptional iPod docking station.When The Bridge is connected to the AVR and aniPod properly docked, you may use the TC 30 or ZR 10 remote to control the iPod for audio playbackusing either the TC 30 or ZR 10 remote, while usingthe front-panel display and on-screen semi-OSD mes-sages to help you locate tracks or view informationabout the track being played. In addition, connectingan iPod to the AVR 745 through The Bridge alsocharges the iPod’s battery.

In addition to providing forcontrol over the selection of the remote source and itsvolume, the AVR 745 offers a comprehensive range ofoptions for powering the speakers in the second zone.• Using the line-level Multiroom Audio/VideoOutputs 8L, the selected source may be fed tooptional, external power amplifiers that may bematched to the specifics of the installation.• When the main room system is configured for 5.1operation, the Surround Back Left/Right amplifierchannels may be used to power the remote zone sothat no additional amplifiers are required.• Using built-in A-BUS/READY technology, optional A-BUS modules may be connected to the AVR 745via a single Category 5/5e or higher cable, so thatremote zone speakers may be powered directlyfrom the A-BUS module without the need for addi-tional power, IR sensor or volume control wires tobe run to the second zone.In addition, the AVR 745 includes a remote IR sensorinput so that remote control commands from the ZR 10 remote included with the unit may be transmittedto the unit, while standard IR input/output jacks allowthe remote zone’s commands to be sent to compatibleIR-controlled source devices.InstallationAlthough simple remote room systems may beinstalled by the average do-it-yourself hobbyist,the complexity of your multizone/multiroom systeminvolves running wires inside of walls where the ser-vicesof a specially trained installer may be required.Regardless of who does the work, please rememberthat local building codes may govern in-wall electricalwork, including proper specification of any wiring usedand the way in which it is connected. You are respon-sible for making certain that all multiroom installationwork is done properly and in compliance with all appli-cable codes and regulations.For standard installations, follow the instructions shownon page 17 for the connection of speaker wire and IRremote wiring to the AVR 745.For installations where the Surround Back Left/Rightamplifier channels are used to power the remote zone,make certain that the system is configured for thattype of operation, as shown on this page.For installations where A-BUS modules are used, fol-low the instructions provided with the A-BUS remotemodules or keypads. Additional information will also bemade available through the Harman Kardon Web siteat www.harmankardon.com.RS-232 ControlThe AVR 745 provides the capability for full bidirec-tional remote control from compatible computers orspecialized remote control systems. RS-232 program-ming requires specialized programming knowledgeand for that reason we recommend that it only bedone by qualified professionals. For more informationon using the RS-232 port for remote control, visit theHarman Kardon Web site at www.harmankardon.comor contact our customer service department.Multiroom SetupOnce the audio and IR link connections have beenmade, the AVR 745 needs to be configured formultiroom operation.To change a setting from its facto-ry default, you will use the MULTI-ROOMSETUP menu. With the TC 30, first press theDevices Button 4on the TC 30 remote and thenpress the Screen Button 6next to AVReceiver and press the Menu Button A.With the ZR 10 remote, press the OSD Button∫to call up the MAIN MENU (Figure 1). Next,press the ⁄/¤Navigation Buttons D©sothat the cursor is next to MULTI-ROOM, thenpress the OK/Enter Button Eon the TC 30or the Set Buttonœon the ZR 10. When theMULTI-ROOM SETUP menu (Figure 33)appears, follow the instructions shown below to makeany needed configuration adjustments.Figure 33When the MULTI-ROOM menu appears, thecursor will be at the MULTI-ROOM line.Sincethis line is used to turn the system on and off, don’tmake an adjustment here unless you wish to turn thesystem on at this time.To turn the system on, press the›Navigation Button D©so that ON is high-lighted. If you do not wish to turn the system on at thistime, or to proceed to the next step, press the ⁄/¤Navigation Buttons D©so that the on-screencursor is next to the MULTI IN line.At the MULTI IN line, press the ‹/›NavigationButtons D©until the desired input to the multi-room system appears in the highlighted video. In addi-tion to direct selection of any active input source, youmay also select the DSP DOWNMIX mode,which outputs a two-channel down-mixed version ofmulti-channel digital sources. When the selection hasbeen made, press the ¤Navigation ButtonD©once so that the cursor is next toMULTI VOL.At the MULTI VOL line, press the ‹/›Navigation Buttons D©until the desired vol-ume level for the multiroom system is entered. DONOT use the regular volume control knobs for this set-ting. When all settings for the multiroom setup havebeen made, press the ⁄/¤Navigation ButtonsD©until the cursor is next to the BACK TOMASTER MENU line. If you have no otheradjustments to make, press the Menu Button Aor the OSD Button∫to exit the menu system.Surround Channel Amplifier AssignmentThe AVR 745 is equipped with seven full-poweramplifier channels to allow for complete 7.1-channeloperation. However, if your system is only configuredfor 5.1 channels in the main listening room, you maytake advantage of the “extra” two channels by usingthem to power speakers placed in a second zonelocation. This enables you to use the multiroom capabili-ties of the AVR 745 without the cost of an additional,external power amplifier.To change the setting so that the Surround Backamplifiers are fed by the source selected through the Multiroom system rather than the SBL/SBR channels of the main room, make certain that theMULTI-ROOM SETUP menu (Figure 33) is on the screen; then press the ‹/›NavigationButtonsD©so that the cursor is pointing to the SB AMPS line. Press the ‹/›NavigationButtons D©so that MULTI is shown inhighlighted video. When this change is made, connectthe wires feeding the remote zone speakers to theSurround Back/Multiroom Speaker Outlets E.When the SBL/SBR speakers are set for multiroomoperation, you may still configure the AVR 745 for 7.1modes in the main listening room by making certainthat the SURR BACK line in the SPEAKERSIZE menu (Figure 27) is set to SMALL orLARGE, as shown in the instructions on page xx.When that is done, the word MULTI will appearnext to the large or small designator to alert you to thefact that the internal SBL/SBR amplifiers are assignedto the multiroom system, and that an optional, externaltwo-channel power amplifier must be connected to theSBL/SBR Preamp Outputs ¡in order to use sur-round back channel speakers. * MULTI-ROOM SETUP *MULTI-ROOM:OFF ONMULTI IN :FM PRESET01MULTI VOL :25dBSB AMPS :MAIN MULTICARRIER OUT: ZONE II BACK TO MASTER MENU→→MULTIROOM OPERATION 51MULTIROOM OPERATION 51MULTIROOM OPERATIONAVR 745 OM 5/15/06 5:00 PM Page 51
