Please note: The use of the wireless microphone system may require a license, depending on the country of use. For detailed information please contact the relevant authority in your country.
Pilot tone
The pilot tone function protects a wireless microphone system against interference, for example, unwanted signals from other radio transmission systems. The transmitter adds a second, inaudible signal (the pilot tone) to the actual signal which is to be transmitted. The receiver identifies it as the matching pilot tone and frees the associated signal. Signals without a matching pilot tone remain muted.
