The pilot tone feature protects a wireless microphone system against interference from unwanted signals, for example from other radio
equipment. The transmitter adds a second inaudible signal, the pilot tone, to the signal to be transmitted. The receiver identifies this as the
matching pilot tone and frees the corresponding signal. Signals without pilot tone remain muted.
