The present invention is directed to an audio system for playing back recorded information by remote transmission. At the transmitting end of the system, an analog audio signal acquired by a server from a recording medium is first converted into a digital data signal, and then a signal created by superimposing the digital data signal with a stereo signal is transmitted out. At the receiving end, an input circuit receives the superimposed signal transmitted over a cable from the transmitting end, and separates it into the digital data signal and the stereo signal; then, the digital data signal is converted back into the analog audio signal which is output to speakers for stereo playback. As, of the plurality of signals to be transmitted, two signals are combined into one signal for transmission, the number of connecting cables can be reduced.
