　　1、 Shop batteries for wireless microphone transmitters. In order to avoid signal distortion and frequency interference during normal use of the system, sufficient batteries must be used. If conditions permit, alkaline 9V batteries are preferred.

　　2、 How to know whether the transmitter battery energy is sufficient as early as possible? In wireless microphone systems of various brands and models, most receivers do not have the transmitter battery energy display function. Although some wireless transmitters have low voltage battery display, users rarely pay attention to this problem in use. In the normal use of wireless microphones, audio signal distortion or frequency interference caused by insufficient battery often occurs. In order to prevent this phenomenon, the operator can timely use the PFL pre listening function of the mixing console during the normal use of the wireless microphone, and monitor the signal of the wireless microphone with headphones. If the sound clarity is slightly reduced or the noise is slightly increased, the battery should be replaced immediately, so as to avoid the psychological pressure caused to the operator due to insufficient battery energy as far as possible.

　　3、 How to change the battery during the performance. It shall be convenient, fast and simple to replace the battery during the performance. A good way is to turn on the "mute" switch of the mixer channel to make the wireless microphone mute. If the mixer without this function can turn off the output volume of the wireless microphone receiver first, then turn off the transmitter power, turn on the transmitter power after replacing the battery, and then restore the receiver output volume to the original gain. If the receiver does not have an output volume switch, You can turn off the mixer input gain or use the Line/MIC selector to switch. After replacing the battery, turn on the machine and reset the mixer input gain or selector.

　　Why not turn off the plug of the wireless microphone channel and replace the battery? It needs to be noted here that it is troublesome to replace the battery by closing the channel pusher. Generally, the microphone has effect processing sound during singing. If one microphone is used, the other wireless microphone needs to

　　When replacing the battery, if you turn off the channel pusher, you should also turn off the auxiliary channel potentiometer for reverberation and time delay. If you forget to turn off the auxiliary channel potentiometer, when replacing the battery, the power impact sound of the wireless microphone transmitter will be output from the auxiliary channel to the mixer through the effector, directly affecting the sound effect; In addition, if the auxiliary potentiometer is leaked after the battery is replaced, there will be no sound effect, which will affect the sound effect.
