A wireless audio distribution system may have a wireless transmitter, responsive to a plurality of audio input channels, for transmitting signals carrying the audio, a receiver, responsive to the transmitted signals for selecting one or more of the audio input channels to be reproduced in accordance with local setting selectors at the receiver. Speaker audio channel anti-noise signals can be subtracted from the head audio channel to cancel the noise related to the playing of the speaker audio on the speakers while the headset audio is played on the headset. Analog anti-noise signals can be produced by use of a microphone associated with the headset and later subtracted from the headset audio.

Noise cancellation for wireless audio distribution system

A wireless audio distribution system includes a wireless headset for receiving a serial, digital bitstream including control data interspersed with digital data related to the audio channels, a manual audio channel selector switch; a manual volume adjustment control, an error detector and a muting circuit selectively reducing the volume level of the audio reproduced by the wireless headset in multiple steps based on errors detected by the error detector.
