To refresh your memory, the squelch system in a wireless microphone receiver operates in a manner similar to a noise gate in an audio system.Its main job is to mute or « Squelch » the receiver’s audio output if the receiver loses the microphone transmitter’s signal.

Should the squelch be high or low?
