1. Introduction
Thank you for purchasing our product. This wireless microphone system operates in VHF
band frequency with crystal controlled. Please read this instruction manual carefully before
operating the system. This manual covers the function and operation of the wireless
microphone system.
2. Safety
Do not spill liquid on the appliance and do not drop it on a hard concrete floor.
Do not place the appliance near heat sources such as radiators, amplifier, or etc. Do
not expose it to direct sunlight, extremely dust, excessive moisture, or vibration.
Take out the battery from transmitter, if the appliance has been not used for a longer
period. This will avoid the damage resulting from a defective leaking battery

5. Product Description
5.1 Receiver
These are the stationary receivers for use with our VHF transmitters (DC3V operating
voltage). The receiver operates in VHF band frequency with quartz locked controlled.
Powered by 12V DC.
Switch the transmitter and hi-fi appliance (amplifier, tape deck etc.) power on.
Test the microphone and adjust the levels on your audio mixer or amplifier.
5.1.1 Single Channel, Non-Diversity
7.5.2 Connecting an instrument
Use the supplied screwdriver to adjust the GAIN at appropriate position.
Plug the 6.3ϕ phone plug of the optional guitar cable to the output jack on the instrument
and the 3.5 Ø plug into audio input connector on the bodypack transmitter.
Switch the transmitter and hi-fi appliance (amplifier, tape deck etc.) power on.
Play the instrument for testing and adjust the levels on your audio mixer or amplifier.

Before checking sound, move the transmitter around the area where you use the system
to look for dead spots. If you find any dead spot, change the receiver position.
If it
does not work, avoid such places.
If undesirable noise occurs, adjust the SQUELCH control on receiver in clockwise to
suppress it. The higher squelch control, the lower the sensitivity of the receiver and
decrease the service area of the system.

5.1.2 Single Channel, Diversity
Check that the transmitter and receiver are using same
frequency.
Check whether the hi-fi appliance is switched on and the receiver
output is connected to audio mixer or amplifier input.
Check whether transmitter is too far away from receiver or
SQUELCH control set too high.
Check whether receiver is located too near metal object or there
are obstructions between transmitter and receiver.

Mixing Switch: When the MIXING switch is in the OFF position, the AF output for
channels 1 and 2 are separated. When the MIXING switch is in the ON position, the AF
output for channels 1 and 2 are mixed, so that both AF outputs have combined signal from
both channel 1 and channel 2.
Unbalanced 6.3mm mono jack audio output for connecting to, e.g., a guitar
Select AF output level for Mic (-20dB) or Line (0dB).
10. DC Jack: DC input connector for the supplied AC adapter.
7.2 Connecting the receiver to an audio mixer or an amplifier
In order to make sure the sound quality and avoid distortion, please adjust the MIC/LINE
switch according to following instructions.
When using a standard audio cable with XLR or 6.3ϕ phone plugs to plug into the MIC
IN on the audio mixer or on the amplifier, please select the MIC/LINE switch to “MIC”
position, the output level for unbalanced output is about at 100mV.
When using a standard audio cable with XLR or 6.3ϕ phone plugs to plug into the LINE
IN on the mixer, please select the MIC/LINE switch to “LINE” position, the output level
for unbalanced output is about at 1V.
7.3 Inserting batteries into the handheld microphone / bodypack transmitter
Push to open the battery cover and insert batteries into the battery compartment
conforming to the polarity (+)(-) marks. The transmitter can not work with incorrectly
inserted batteries.
When push the ON/OFF switch to “ON” to switch the power on, the LED will flash
momentarily.
If the battery has sufficient power, the LED flashes once. If the LED stays on, it
indicates that the battery has insufficient power and should be changed soon. If the
status LED fails to flash, the battery is either dead or not positioned correctly, and you
should correct the positioning or change the battery.
Push back the battery cover to click it shut.
7.4 Setting up the handheld microphone transmitter
Check the transmitter and receiver are using the same frequency.
Switch the receiver power on, select the AF output level on Mic (-20dB) or Line (0dB)
position.
Switch the transmitter and hi-fi appliance (amplifier, tape deck etc.) power on.
Test the microphone and adjust the levels on your audio mixer or amplifier.
