Abstract: The present invention may be used for selectively listening to multiple audio signal sources in a local area. Multiple audio signals from multiple audio signal sources may be combined in a wireless transmitter. The combined audio signals may be converted to an electromagnetic signal for transmission to multiple personal receivers. Each of the audio signal sources may be identified by a unique, visible channel designator. The electromagnetic signal may be received by the personal receivers and reconverted into each of the audio signals. The audio signals may be detected in the personal receivers to identify each to an audio signal source. A user may select a specific audio signal source for a personal receiver and the audio signal may be output to an earphone.
