How to debug wireless microphone

Turn on the switch of wireless microphone transmitter and receiver to test whether there is audio pulse. You can see if there is an audio pulse on the receiver. You can also use headphones to monitor whether there is sound in the receiver and whether the volume is standard. If the volume is too low or too high, you can adjust it by the volume adjustment button of the microphone transmitter.

The receiver can adjust the listening volume. After the wireless microphone is debugged, it depends on whether the camera has audio pulses. You can also use headphones to monitor the quality and size of the sound on the camera, and then make corresponding adjustments.
