The principle of microphone is that when a person speaks into the sound source microphone, sound waves make the diaphragm vibrate, the diaphragm suddenly loosens and tightly squeezes the carbon particles, and the resistance changes accordingly, resulting in a current that changes with the sound vibration in the circuit, that is, the microphone is equivalent to a variable resistor.

The correct operation method of wireless microphone is: connect the wireless microphone receiver and audio system power supply, set the audio system level (0DB or +4DB), then turn on the wireless microphone transmitter power supply, set the audio output gain of the wireless microphone transmitter to 70% ~ 75%, and set the channel potentiometer of the wireless microphone input channel on the mixer to 0 dB; Finally, carefully adjust the input gain of the mixer, and if necessary, slightly adjust the audio output gain of the transmitter until the microphone effect is satisfactory.
