Conversely, if the output is set too low, the overall signal-to-noise ratio of the system may be reduced, causing noticeable hiss. If such noise occurs, adjust the output level of the receiver so that highest sound pressure level going into the microphone transmitter causes no input overload in the mixer, but permits the mixer level control to operate in the normal range (not too high and not too low). This provides the optimal signal-to-noise for the entire system.UÊivÀiÊÃiÀÌ}ÊÌiÊL>ÌÌiÀiÃ]ÊiÃÕÀiÊÌ>ÌÊÌiÞÊ>ÀiÊÃiÀÌi`ÊÜÌÊÌiÊVÀÀiVÌÊ«>ÀÌÞ°UÊivÀiÊ«iÀ>Ì]ÊVwÀÊÌ>ÌÊÌiÊÀiViÛiÀÊ>`Ê>ÃÃV>Ìi`ÊÌÀ>ÃÌÌiÀÊ>ÀiÊÌÕi`ÊÌ the same frequency group and channel number.UÊvÌiÀÊ>}Ê>ÊÀiViÛiÀÊV>iÊV>}i]ÊiÃÕÀiÊÌ>ÌÊÌiÊVÀÀië`}ÊV>}iÊà also made on the matching transmitter.UÊ1ÃiÊÞÊiÜÊ>>iÊÀÊvÕÞÊÀiV>À}i`Ê ÊL>ÌÌiÀiðÊÊÌÊÕÃiʺ}iiÀ>Ê «ÕÀ«Ãi»ÊV>ÀLÊL>ÌÌiÀiðÊ7iÊL>ÌÌiÀiÃÊ>ÀiÊÜi>]ÊÀi«>ViÊ>ÊÌiÊL>ÌÌiÀiÃÊ>ÌÊÌi same time.

Therefore, the supplied capacitor provides first-order filtering of the RF signal from the cord into the guitar and eliminates virtually all scratchy noises. Should your equipment still produce scratchy noise, we suggest these steps to eliminate prob-lems:1) Make sure all guitar volume and tone pots are clean and all contacts are solid. This is very important.2) Solder a 47pF capacitor across the pot to ground terminal of the guitar’s volume and tone pots to provide extra filtering.8.

8U-800 RECEIVERButton FunctionThe POWER ON Button (1) is used to power receiver ON or OFF. When thepower button is pressed, the POWER LED (2) and the white backlight on the LCDDISPLAY (5) will light up indicating the receiver is ready. Press the Power buttonagain to turn off the receiver. The power LED and the backlight on the LCD will be offindicating the receiver is off. At power-off the U-800 receiver will store the last settingsentered and re-display them at power-on. It can be reprogrammed to any newGroup/Channel, or Mute level. The default factory setting is Group 11, Channel 01and Mute 0 on the first LCD menu screen.The UP BUTTON (16) is pressed one step at a time to SCAN, IR or to increaseGROUP, CHANNEL, MUTE by one level each timeThe DOWN BUTTON (17) is pressed one step at a time to decrease GROUP,CHANNEL, MUTE by one level each timeThe MENU BUTTON (18) is pressed one step at a time for Auto Scan Frequencyor to Automatic GR/CH ASC™ Sync, or if pressed repeatedly the LCD DISPLAY (5)menu will cycle through the following screens. Press the MENU BUTTON (18) andthe UP BUTTON (16) at the same time to lock or unlock the keyboard/buttons. During manual programming, press the MENU BUTTON (18) to confirm the selectionand advance to the next menu before the Auto Programming Function takes overafter 5 sec.Rack Mounting the ReceiverThere are 2 options available for rack mounting the U-800 receiver: singly or sideby-side with another U-800 receiver. a. Single mounting: Remove the receiver SIDE MOUNT CLIP (24) from each side of the receiver (as shown) and slide in the optional ERM-12 RACK EARS (25). b. Side-by-side double mounting: After removing the SIDE MOUNT CLIPS (24) from both U-800 receivers join the two receivers with the EJC-3 JOINING CLIP (26) and attach the ERM-22 RACK EARS (27) as shown.(Note: Do not mount the receiver in a rack directly above an amplifier or other sourceof high heat — this could degrade the performance of the U-800. Always ensure ad-equate airflow and heat dissipation in any rack configuration.)5. SYSTEM OPERATION17FeedbackAvoid acoustic feedback (howling or screeching) by taking care in selecting PAvolume, transmitter location and speaker placement.Please also note the pickup pattern characteristics of the microphone selected.Unidirectional microphones are more resistant to feedback. However, they pick upsound sources best that are directly in front of the microphone. Also, mics that arefarther from the sound source (such as a handheld) require more acoustic gain andthus are also more prone to feedback than close-source mics.No or Low AudioIf you are not getting audio through the system, carefully re-check all setups.Especially note that the receiver and transmitter must be set to operate on the sameRF channel. Also confirm that the transmitter’s AUDIO MUTE (36, 40) is not in theOFF position. The receiver’s UNBALANCED LINE OUT (19) is adjustable so makesure the VOLUME CONTROL (21) is set properly.RF Interference and Finding Open ChannelsThe FCC mandates the following information be provided to all end users of thisequipment:Consumer AlertMost users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50mW); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change.For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC)or visit www.fcc.gov/cgb/consumerfacts/wirelessmic_factsheet.html.If you encounter slight receiving interference when the transmitter is far from thereceiver (from other than an operating TV station on the same frequency), it canoften be overcome by adjusting the receiver‘s MUTE LEVEL/SQUELCH (13)pÃiiAdjusting the Mute Level / RFSquelch.If receiving interference on a selected channel with the transmitter off, or if you en-counter interferences in operating multiple U-800 systems simultaneously at the samelocation see: “6.

16Receiver/Transmitter ASC™ IR Sync Manual ProgrammingTo manually program the pre-selected Group/Channel (frequency) from the receiverto the transmitter, place the transmitter’s IR RECEPTOR SENSOR WINDOW (37,44) 6-12” away from the receiver’s IR WINDOW (4). Press the MENU BUTTON(18) four times to the IR Screen Display and then press the UP BUTTON (16) tostart IR programming. The flashing IR INDICATOR (10) icon indicates IR transmissionis in progress. When the synchronization is completed successfully (usually inless than 2 seconds), the RF INDICATOR (8) and the diversity A or B INDICATOR(9) on the receiver will display, indicating that the IR linking is completed. TheLCD DISPLAY SCREEN (5) will show the selected channel. If the UP button is notpressed during the two seconds of active data transfer, the IR INDICATOR (10) willnot flash, the LCD Display will revert to the main menu, the receiver will not link to thetransmitter, and the transmitter’s previously programmed channel remains unchanged.Instructions for Setup of Simultaneous Multichannel OperationThis U-800 receiver is capable of finding an open channel with its autoscan capability.This built-in feature is a quick, convenient way to set up many wireless systems atthe same location for simultaneous multichannel operation.If you are using multiple transmitters at the same location, set up the first transmitter and leave it ON and keep 10 feet away from the receivers and 1 foot away from transmitter to transmitter. This avoids possible duplicate selection of the same channel as already se-lected for the first receiver. Then start the autoscan function on the second receiver. Repeat this procedure for all receiver/transmitters to be used in your system. Finally with all the transmitters ON, perform a range walk test in the location these systems will be used in to check for potential crosstalk interference in this application.If you are not satisfied with any of the channels scanned, repeat the autoscan procedure for that receiver again anytime for finding another free channel.This process can be simplified if you select channels within Factory SELECTED Groups11 to1A, as the channels within those groups are mutually compatible (unless there isoutside interference on any of the selected frequencies). If there is any such interference in your location, select as many channels as you can using these 10 groups andthen select additional open channels as needed (depending on number of systems tobe operated simultaneously) from Groups 1B to 1F. As noted above all these groupswill retain in memory the previously selected channels for that group for easy setupsubsequently in that same location.9Powering the ReceiverPlug the AC/DC ADAPTER (23) provided into the DC INPUT JACK (20)on the back of the receiver. Then plug the power supply into an AC outlet. (Note:Any 22V DC source with 400mA capability can also be used.) Press the POWERSWITCH (1) once to turn on the receiver. The POWER ON LED (2) and the LCDDISPLAY (5) will now light and the receiver is operational.Adjusting AntennasThe U-800 has two permanently attached, flexible-elbow ANTENNAS (3) for diver-sityreception. Unfold and rotate these antennas to operate the receiver. The optimalpositions of the antennas are flared 45° out from the receiver sides and 90° from eachother. For maximum range, it is always best to maintain a line-of-sight (no obstructions) between the receiver antennas and the transmitter at all times whenever possible.Adjusting the Mute Level/ RF SquelchThe MUTE LEVEL/RF SQUELCH (13) can be changed anytime during the mainscreen display to quiet the receiver in high noise environment condition. The controlranges are from level 0 to level 5. The level should be adjusted to a lower numberfor the minimum RF squelch setting at which the RF INDICATOR (8) will remain onwhile your transmitter is in normal use, up to the maximum operating range anticipated in use for your application. However, in areas of high RF activity, the squelchcontrol may need to be adjusted to a higher number. If the transmitter is off and thereceiver’s signal RF INDICATOR (8) or the diversity A or B INDICATOR (9) flickers or stays on continuously, the squelch should be adjusted to a higher number to stop the flickering. Be careful not to select too high a number setting as this may reduce the operating range to below what is needed. A range walk test will help in selecting the proper level. If the range is not critical, note that a higher level (maximumsquelch) setting will also yield a quieter mute function, which might be desired incertain applications. The squelch level is factory preset at maximum sensitivity andoperating range (i.e. level 0 for minimum squelch level—maximum usable range).Note: For easier intuitive operation, the MIN and MAX indications for this controlrefer to the minimum and maximum operating range settings, not to the actual mutelevels selected, which are the opposite as per above.Keyboard/Buttons Lock FunctionUse keyboard/Buttons Lock Function to lock or unlock the receiver controls, preventing accidental adjustment during use: You can push and hold MENU BUTTON (18),then push UP BUTTON (16) to lock; push and hold MENU BUTTON (18), thenpush UP BUTTON (16) again to unlock. The Keyboard/Buttons must be unlockedbefore you can make a selection: AUTO SCAN, Group/Channel or MUTE levels.
10Audio Level and Peak LED IndicatorThe U-800 receiver has a 5 bar AF LCD (7) display that typically shows a few barsindicating normal level audio signal from the transmitter. Occasional flickering ofthe fifth AF LCD (peak level) on loud inputs to the transmitter is normal. If the AF LCDlights up full bars continuously decrease the input audio level to the transmitter oroverload distortion may result.Connecting the Audio OutputThe U-800 receiver has two type of outputs available, an adjustable level ¼”UNBALANCED LINE OUT (19) and a fixed level MIC out BALANCED MICOUT XLR JACK (22). The ¼” unbalanced line out is controlled by the VOLUMECONTROL (21).For unbalanced line output connection, plug an audio cable with a ¼” mono(Tip/Sleeve) plug into the Unbalanced Line Out jack and plug the other end into yourmixing board or amplifier. Adjusting the Volume control will increase or decrease theaudio level at the ¼” Unbalanced Line Out only.(Note: When using the UB-800 instrument transmitter system, connect theUnbalanced Line Out directly to your instrument amp or preamp. At maximumreceiver volume setting, the system output is approximately +4dB higher than a directcord-to-amp connection.)For balanced Output connection, plug an audio cable with an XLR connector into theBalanced Mic Out XLR Jack socket and plug the other end into your mixing board oramplifier and control the audio levels from there. Both the ¼” Unbalanced Line Out and the XLR Balanced Mic Out can be used at the same time to connect to your mixing board, effect, or amplifier. Please follow below drawing for the audio cable/connector wiring. Your U-800 receiver is now operational and ready to use. Proceed to the following instructions for the UH-800 handheld microphone transmitter or UB-800 bodypack transmitter included with your system.Note: As when making any connection, make sure the amplifier or mixing board volume is at the minimum level before plugging in the receiver to avoid possible sound system damage.Note: Only one transmitter can be used with one receiver. It is not possible to use two transmitters on the same frequency and mix the output of these transmitters into one wireless receiver.F-XLRPin 2: +Pin 2: +1/4” PlugSLEEVE TIPPin 1: GroundTip = signal (+)Sleeve = ground15after receiver is powered off. This facilitates easy setup by enabling quick selection of stored channels for any group, i.e, selecting any group will automatically display the last channel selected for that group. See section “11. U-800 Frequency Lists” for available channels in each group. The previous group and channel used is stored in memory automatically when receiver and transmitter are turned off after operation. Selecting a different group on the receiver in subsequent use will display a differ-ent channel as previously selected for that group, however, the transmitter will need again to be sync’ed to that new frequency to complete the system setup for operation.

14Connecting Input Audio SourceLapel/Head Mic Uses (UB-800 LT/HM)The mini 3.5mm locking INPUT JACK (39) is for connecting the audio input from alavaliere/lapel Mic (LT), a Head Mic™ (HM), or an instrument (GT) cable, dependingon which transmitter version is being used. Secure the connection to the cable by tighten-ing the cable mini plug’s outer ring counterclockwise. When ready to play, slide theAUDIO MUTE ON/OFF SWITCH (40) to the ON position to un-mute the audio.Adjust the INPUT VOLUME LEVEL (43) on the transmitter for suitable level.Instrument Use (UB-800 GT)Secure the connection of the GT (instrument) cable by tightening the mini plug outerring counterclockwise onto the 3.5mm locking INPUT JACK (39). When readyto play, slide the AUDIO MUTE ON/OFF SWITCH (40) to the ON position toun-mute the audio. Adjust the volume on the receiver for one-to-one unity gain witha hardwired cord or select up to an added 4-5dB boost by adjusting the receivervolume to maximum for normal use with guitars and bass guitars.Note: The audio level should be adjusted on the instrument as when using a hardwiredcord.Programming the UB-800 to the Selected Group/Channel (frequency)The transmitter must be programmed to the same frequency as selected for the receivervia automatic synchronization using the IR ASC™ Sync function. It cannot be pro-grammed on the transmitter itself. See next section “6. Selecting Group/Channel,IR Programming and Simultaneous Multichannel Operation”.Note: Note: The transmitter should be turned ON and ready for the IR communica-tions with the receiver IR receptor for the following process.Note: If no button is pressed within the five seconds period during a selection, theprogram is terminated and the process needs to be repeated.Note: For normal operation, the transmitter should have the same channel as dis-played on the receiver.Choosing Group/Channel for the SystemThe receiver offers a choice of 15 groups: 10 that are Factory PRESET (Group 11to 1A) and 5 that are User SELECTABLE (Group 1B to 1F). If the Factory PRESETGroup mode is chosen, only a limited numbers of channels are available in thesegroups. For most convenient setup, each of these groups offers from 3 to 14 channels(depending on group selected) to choose from that are factory preset for simultaneousmultichannel operation compatibility and are retained in memory after the receiveris powered off. For the User SELECTABLE Group 1B-1F mode, a letter “U” will lit upon the LCD DISPLAY (5) instead of the CHANNEL (12) number as in the FactoryPRESET Groups. Each User SELECTABLE Group has 800 channels to choose fromeither by manually selecting a channel or using the Auto-Scan in 1MHz segmentincrements at a time within the frequency band and they are retained in memory6. SELECTING GROUP/CHANNEL, IR PROGRAMMING AND SIMULTANEOUS MULTICHANNEL OPERATION11Programming the U-800 to the Selected Group/Channel (frequency)The Receiver must be programmed for a Group/Channel (frequency) first then auto-matic synchronization using the IR ASC™ Sync function to the transmitter.
