PRODUCT DESCRIPTIONINTRODUCTION12Wireless Wireless1233456789Fig.1 16 channels model Fro nt pa nelFig.2 64 channels model Fro nt pa nel1. Introduction Thank you for purchasing our product. This in-ear monitor system operates in UHF band frequency with Phase Locked Loop (PLL) synthesizer controlled. The system with 16 or 64 selectable frequencies via PLL circuitry makes it easy to choose non-interfered channels. Please read this instruction manual carefully before operating the system. This manual covers the function and operation of the in-ear monitor system. 2. Safety  Do not spill liquid on the appliance and do not drop it on a hard surface.  Do not place the appliance near heat sources, such as radiators, amplifier, etc.. Do not expose it directly to sunlight, extremely dust, excessive moisture, or vibration.  Unplug the power if the appliance has been not used for a long period. This will avoid the damage resulted by surge electricity. 3. Feature  IEM-168 is a Low-Power FM broadcasting transmitter. At the same time, it can send out stereo music (work with CD player, MP3, etc.) and vocal broadcasting (works with wired or wireless microphone system).  There are up to 16 or 64 selectable channels to set up a multi-channels broadcasting system and to avoid the frequency inference. Also, the LED displayer gives us a clear channel indication. And, user can select channels or groups easily by using rotary switch.  The stereo audio signal (works with CD player, MP3, etc.) can be input easily through the RCA jack.  The wired microphone can be connected to the 6.3Φ jack or to the XLR connector.  The Peak LED indicator can help avoiding the audio distortion.  User can plug a headphone into the headphone jack on the front panel to monitor the sending out audio signal.  IEM-168’s antenna is a high efficiency antenna. The service area can be improved when the antenna is placed at higher location.  IEM-168 can combine with a RF power booster (AB-168, which is 1Watt max) to used for an over 1 km area service. 4.

SETTING-UP3Wireless Wireless SETTING-UP410 1 1 12 13 145.2 Setting up the transmitter  Connect 6.3Φ plug or XLR plug of the wired microphone in MIC IN jack on the transmitter rear panel. Turn the MIC Volume Control on the transmitter clockwise to set the transmitter input to receiver level.  Use the RCA plug to connect the Audio In jack on the transmitter rear panel. Turn the Line Volume control on the transmitter clockwise to set the transmitter input to receiver level.  For monitoring purpose, plug the headphone into the monitoring headphone jack on the front panel of transmitter. Turn the Monitoring Headphone Volume on the transmitter clockwise to set the headphone volume. 5.3 Setting up the frequency  For 16 channels model, adjust channel rotary to select channel to set up frequency.  For 64 channels model, frequency is divided into 8 groups, which there are 8 channels in each group. Adjust group rotary to setup group number. Adjust channel rotary to setup channel number. Fi g.3 r ear p ane l5. Setting-Up NOTICE: Prior to setting up, please make sure the microphone and the receiver are turned to the same frequency. Two or above wireless microphones operating in the same frequency can not be used at the same time and area. So please select the different frequencies which cam be used simultaneously at the same area. 5.1 Connecting the transmitter to power  Attach the UHF antenna to the TNC connector on the rear panel.  Please check the voltage of the supplied AC adapter conforms to the voltage available in local area. Using the wrong AC adapter may cause irreparable damage to the unit.  Plug the feeder cable of the supplied AC adapter into DC IN socket on the transmitter. Then plug the AC adapter into a power outlet. THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS SUBJECT TO THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIRED OPERATION.Notice : The changes or modifications not expressly approved by the party responsiblefor compliance could void the user’s authority to operate the equipment.IMPORTANT NOTE: To comply with the FCC RF exposure compliance requirements, no change to the antenna or the device is permitted. Any change to the antenna or the device could result in the device exceeding the RF exposure requirements and void user’s authority to operate the device.
SPECIFICATIONTROUBLE-SHOOTING56Wireless Wireless6. Trouble-shooting Problem Solution No sound  Check the power supply of the transmitter and receiver.  Check that the transmitter and receiver are turned to the same frequency.  Check whether the Hi-Fi appliance is switched on and the transmitter output is connected to mixer or amplifier input.  Check whether receiver is too far away from transmitter.  Check whether transmitter is located too near metal object or there are obstructions between transmitter and receiver. Sound interference  Check the antenna location.  When using 2 or above transmitters simultaneously, make sure that the chosen frequencies are not interfered.  Check whether the interference comes from other wireless microphone, TV, radio and etc.. Distortion  Check the volume control for transmitter is adjusted too high or too low.  Check whether the interference comes from other wireless microphone, TV, radio and etc.. 7. Environment When disposing the equipment, remove the screws, separate the case, circuit boards, and cables, and dispose of all components according to local waste disposal rules. 8.
