1. Introduction
Thank you for purchasing our product. This wireless microphone system operates in UHF
band frequency with synthesizer controlled. Thesystem with 16 or 64 selectablefrequencies
via PhaseLocked Loop (PLL) circuitry makes it easy to choosenon-interfered channels.
Pleaseread this instruction manual carefully before operating thesystem.This manual
covers the function and operationof thewireless microphone system.
2. Safety
ØDo not spillliquidon theapplianceand do not drop it on ahard concrete floor.
ØDo not place the appliance near heat sources such as radiators, amplifier, oretc. Donot
expose it todirect sunlight, extremely dust, excessive moisture, or vibration.
ØTakeout the battery from transmitter, if the appliance has beennot used fora longer
period. This will avoid the damage resulting from a defective leaking battery
3. Environment
ØDo not throwused batteries into afire or garbage bin with domestic rubbish. Be sure to
disposeof usedbatteries inaccordance with local waste disposal rules.
ØWhen disposing the equipment, remove the batteries, separatethe case, circuit boards,
and cables, and dispose of all components inaccordancewith local waste disposal rules.
4. Wireless Note
ØBefore setting up, make sure that the transmitter and receiver are tuned to the same
frequency.
ØDo not use two transmitters inthe same frequency.
ØUse good quality batteries toavoid the damage resulting fromadefective leakingbattery.
ØTurn thevolume controlon thereceiver to adjust receiver output level to match input level
requirements of amixer or amplifier. Pleasesee 7.2）
ØWhilechecking sound, move thetransmitter around the area where you use the systemto
look for dead spots. If you find any dead spot, change thereceiver position.If it does
not work, avoid suchplaces.
ØTo avoid interference, do not put the receiver toonear metal object and avoid obstructions
between transmitter and receiver.
ØAvoid theinterference fromTV, radio, otherwireless appliances and etc.

7. Setting Up
NOTICE: Prior tosettingup, check that the transmitter andreceiver are tuned to thesame
frequency.Two or above transmitters operating in thesame frequency cannot be
used at thesame timeand area, so please select thedifferent frequencies which can
be used simultaneously at local area.
7.1 Connectingthe receiverto power
ØPlug the antennas into theTNC socket onthe receiver and point them upward.
ØCheck that thevoltage of thesupplied ACadapter conforms to the voltage available (AC110 or
220) in local area. Using the wrong AC adaptermay causeirreparable damage to theunit.
ØPlug the feeder cable of the supplied AC adapterintoDC INsocket on the receiver.Then
plug the AC adapter into apower outlet.
7.2 Connectingthe receiverto an audio mixer oran amplifier
In order tomake sure thesound quality and avoid distortion, pleaseadjust the volume level
according to following instructions.
7.3 Insertingbatteries intothe handheld/ bodypack transmitter
ØPushto openthe battery cover and insert batteries intothe battery compartment conforming to
the polarity (+)(-) marks. Thetransmitter can not work with incorrectly insertedbatteries.
ØWhen push the ON/OFFswitchto “ON”to switch the power on, the LED will flash momentarily.
If the battery has sufficient power, the LEDflashes once.If the LED stayed on, it indicates
that the battery has insufficient power and should be changed soon. If thestatus LED fails to
flash, the battery is eitherdead or not positioned correctly, andyou should correct the
positioningor change thebattery.
ØPushback the battery cover to click it shut.
7.4 Setting up thehandheldtransmitter
ØSwitch the receiver power on and check the frequency and volumelevel.
ØSwitch the transmitter andhi-fiappliance (amplifier, tape deck etc.) power on.
ØTest the microphone and adjust the levels onyour audio mixer or amplifier.

ØWhen using astandard audio cable with 3-pin XLR connectors or 6.3
j
phone
plugs to plug into the MIC IN onthe audio mixer or on theamplifier, please turn
the VolumeLevel Controlon thereceiver to around 1o’clock position, the
output levelfor balanced and unbalanced output is about at 77mV.
ØWhen using astandard audio cable with 3-pin XLR connectors or 6.3jphone
plugs to plug into the LINE IN onthe audio mixer or on theamplifier, please
turn the VolumeLevel Control to around MAX. position on the receiver, the
output levelfor unbalanced and balanced output is about at 770mV.
Never use the balanced andunbalanced audio outputs at thesame time!This may cause
signal loss or increased noise.

screwdriver to adjust the GAIN at appropriate position.
ØPlug the 6.3jphoneplug of theoptional guitar cable totheoutput jack on the instrument and
the mini XLR (3.5jplug) into audio input connector on the bodypack transmitter.
ØSwitch the transmitter andhi-fiappliance (amplifier, tape deck etc.) power on.
ØPlay theinstrument for testingand adjust the levels on your mixer or amplifier.
MIC/LINE switchisan optional function only for use with mini XLR connector.
8. Trouble-shooting
Problem Solution
No sound äCheck the power supply of themicrophone and receiver.
äCheck that the transmitter and receiver are tuned to the same
frequency.
äCheck whether the hi-fiappliance is switched on and the receiver
output is connected to audio mixer or amplifier input.
äCheck whether transmitter is toofar away fromreceiver or SQUELCH
control set toohigh.
äCheck whether receiver is located too near metalobject or there are
obstructions between transmitter and receiver.
Sound interference äCheck the antenna location.
äWhen using 2or above microphone sets simultaneously, makesure
that the chosenfrequencies arenot interfered.
äCheck whether the interference comes fromother wireless
microphones, TV, radio andetc.
Distortion äCheck the receiver volume level is set too highor toolow.
äCheck whether the interference comes fromother wireless
microphones, TV, radio andetc.
