PURPOSE:To attain ease of coping with increased number of audio components by providing a remote control analog switch turning on/off an output signal to each audio source and connecting each output terminal and an input terminal of an amplifier section with an audio bus line so as to simplify the connection in constituting the audio system. CONSTITUTION:A line W is an audio bus line connecting an output terminal of each audio source and an input terminal of an amplifier section and forms a signal path for two channels' share in case of stereo type. Further, a control signal bus line CW is provided to apply a selection signal from the amplifier section A to a control terminal of each audio source S. An analog switch 10 (a, b, c,...) is provided to the output side of each audio source S and the analog switch 10 (a, b, c,...) is controlled remotely by a control signal. Thus, an output signal from each audio source S is connected to the amplifier section A via an audio bus line W. |
