Abstract

A system and method of transmitting audio signals. Frequency modulated carrier signals that each have an audio signal are mixed. The mixed signal is converted into a low voltage signal into which a feed voltage is coupled. The coupled signal is transmitted through a single line of a transmission cable to an audio signal infrared transmitter unit.
