This professional wireless microphone system was designed by America technique with a super sensitive VHF
high band frequency receiver and controlled with 15ppm crystal, a put on and put off to hit and cancel circuit.
resist reverberation circuit and changed output controlled slowly ... ect. And designed by a computer EDA
system and finished on its item named pattern line. Every system is available to an excellent electric function
by Q.C. controlled strictly.

FEATURES

 Wide frequency response, high S/N ratio.
 Resist disturbing strongly, be standing by noises output to zero.
 Super silent function, low T.H,D.
 No hitting when putting on the switch, so can protect the amplifier and speakers.
 With a complete working state and power level indicating.
 With a wide using range for over 30m in a good surrounding, for 20m in a duplicate one.
 Duel channel designed, two microphones can use at the same time to sing without any disturbing caused

by.

 Used in the entertainment places as a larger and a middle stage,
 Karaoke hall or at home ... ect.

USING GUIDE INSTRUCTION

OPERATION

 Put the receiver near the audio adjustor, connect with power and the signal protected cord with A.OUT,

B.OUT or MIX.OUT. And then connect with the amplifier or the microphone of the audio adjustor (MIC IN).
Draw out two antennas completely. Put on the power switch, The power indicator shines. This receiver is
being standing by. (Don't put the receiver in a corner in order to work in a good condition)

 Unscrew the cover of battery case, install the battery correctly, then light it up. (There are labels on battery

and battery case, don't install the battery oppositely)

 Put the switch to ON position. The signal lamp will shine at that time. the signal on the receiver available to

the signal channel on. It means that the signal is available for the receiver from the microphone. Adjust the
signal volume switch and the volume switch on the amplifier, keep this system a bit of volume. Speak to the
microphone and output the signals.

 If the signal on the microphone is off or dusky, the battery is being low voltage. means that it needs to

replace a new battery.

Notice

When the power pressure is lower than 7V, il may cause the instability of signal, the shorter effective distance
and the timbre maybe not as good as normal, so please change new battery to avoid these.
