1. Introduction
Thank you for purchasing our product. This PLL synthesized wireless microphone system
operates in UHF band frequency with 15 or 16 selectable channels. 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.
3. Environment
Do not throw used batteries into a fire or garbage bin with domestic rubbish. Be sure to
dispose of used batteries in accordance with local waste disposal rules.
When disposing the equipment, remove the batteries, separate the case, circuit boards,
and cables, and dispose of all components in accordance with local waste disposal rules.
4. Wireless Note
Before setting up, make sure that the transmitter and receiver are tuned to the same
frequency.
Do not use two transmitters in the same frequency.
Use good quality batteries to avoid the damage resulting from a defective leaking battery.
Turn the MIC/LINE switch on the rear of receiver to adjust receiver output level to match
input level requirements of an audio mixer or amplifier.
While 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.
To avoid interference, do not put the receiver too near metal object and avoid obstructions
between transmitter and receiver.
Avoid the interference from TV, radio, other wireless appliances and etc.

Play the instrument for testing and adjust the levels on your audio mixer or amplifier.
8. Troubleshooting
Problem Solution
No sound Check the power supply of the microphone and receiver.
Check that the transmitter and receiver are tuned to the 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.
Sound interference Check the antenna location.
When using 2 or above microphone sets simultaneously, make
sure that the chosen frequencies are not interfered.
Check whether the interference comes from other wireless
microphones, TV, radio and etc.
Distortion Check the receiver volume level is set too high or too low.
Check whether the interference comes from other wireless
microphones TV radio and etc
5. Product Description

7.3 Setting up channel on receiver
Notice: Do not put two or more transmitters operating nearby when setting up the frequency
channel. Please keep transmitter at least one meter away from receiver.
Use the AC adaptor to connect the DC input connector for on the receiver and check the
frequency.
The power LED lights when the receiver is ready to operate
Adjust dip switch to set the channel
If user need to set up a multi-receiver system, please keep your previous
receiver-microphone pair power on. Then go on to next set up procedure.
Make sure the receiver channel is same as the transmitter channel
7.4 Inserting batteries into the handheld / 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.
7.5 Setting up the handheld transmitter
Use the AC adaptor to connect the DC input connector for on the receiver and check the
frequency.

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 fo
r
unbalanced output is about at 1V.
For RS-80:
When select the MIC/LINE switch to “MIC”, please use a standard 6.3ϕ plug cable to
connect the UNBALANCED connector on the receiver rear panel to an unbalanced
MIC. input on the audio mixer or on the amplifier,
When select the MIC/LINE switch to “MIC”, please use a standard 3-pin XLR cable to
connect the BALANCED connector on the receiver rear panel to an balanced MIC.
input on the audio mixer or on the amplifier.
When select the MIC/LINE switch to “LINE”, please use a standard 6.3ϕ plug cable to
connect the UNBALANCED connector on the receiver rear panel to an unbalanced
line input on the audio mixer or on the amplifier.
When select the MIC/LINE switch to “LINE”, please use a standard 3-pin XLR cable to
connect the BALANCED connector on the receiver rear panel to an balanced line
input on the audio mixer or on the amplifier.
For RS-60 / RS-120:
When select the MIC/LINE switch to “MIC”, please use a standard 6.3ϕ plug cable to
connect the UNBALANCED connector on the receiver rear panel to an unbalanced
MIC. input on the audio mixer or on the amplifier,
