A: A wireless microphone works by using a wireless transmitter, which is incorporated into the microphone or attached to a body pack transmitter. The battery-operated wireless transmitter includes an antenna for broadcasting sounds.
Wireless microphones are designed with squelch circuits to mute audio when the receiver loses or cannot find the transmitterâs signal. Squelch circuits are necessary because receivers (especially analog ones) try and demodulate anything they can, including waves that make up the noise floor and interfering signals.he receiver will squelch when it cannot locate the tone key. A tone key squelch can be fooled by rogue harmonics that approximate the tone keyâs frequency or by other nearby microphone transmitters (used by someone other than you) that are also using tone keys.
