PDWM2145 Wireless Microphone System

Warning
This product is designed for an echoic circuit switch,the transformer with last out for a long-time working,so please pull out the pin and turn off “power” when you do not use it.

FOREWORD

Thanks for purchasing this product, please read this instruction carefully so that can understand how to operate the product of the style you bought correctly. Please keep this brochure in a safe place carefully after reading as a reference in the future.
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.

FEATURED

• 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 2Orn 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/INSTYUCTION

OPERATING AND GUIDANCE OF LINK

1. 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 WIC 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)
2. Unscrew the cover of battery case, install the battery correctly, then tight it up. (There are labels on battery and battery case. don’t install the battery oppositely)
3. 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.
4. 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
5. If using several systems, please chose difficult AF machine.

Notice
When the power pressure is lower than 7V, it 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.
