Wireless microphone of conference room audio equipment from sound into a signal, and after modulation into high frequency radio wave transmission, then receive back demodulation, amplification, restore to sound the whole process, there are many links, a link, maybe it can work, but it can reduce its stability, work range, not noticed, will reduce a bit, use scope and narrow point, so accumulation, multiple link vulnerabilities at the same time, wireless microphone is not interference, is "frequency", even very close distance is not normal use.On the contrary, all links have noticed that the wireless microphone anti-interference ability will be greatly enhanced, the stability will be greatly improved.

Operators should carefully check the wireless microphone before the performance or use, correctly connect the system, reasonably set up the antenna, and ensure that the microphone is in the normal work state, mainly pay attention to the following points. So as to avoid the wireless microphone without sound during performance or use.

(1) Check whether the battery box is well contacted and whether the battery has electricity. (2) When starting up, open the receiver first, check the RF head, and determine that the channel has no RF interference, and then open the transmitter. 

(3) Check the microphone mute switch to ensure that the wireless transmitter and microphone are always in the working state. 

(4) Do not stack the receivers together to avoid mutual interference between the receivers. (5) After the use of the end to take out the power supply, because the individual microphone is light touch the switch, are in the standby state, or live work will use up the battery.
