ABSTRACT:
The present invention relates to a multi-channel speaker system and a wiring device thereof. The wiring device for a multi-channel speaker system according to an embodiment of the present invention comprises a serial audio signal circuit and a plurality of audio signal separating circuits. The serial audio signal circuit SAC generates a single serial digital audio signal by synthesizing the plurality of analog signals that are generated by the analog audio signal generating circuit, and outputs the same. The audio signal separating circuit receives the serial digital audio signal and separates a corresponding digital signal, and it converts the separated digital signal to an analog signal. Therefore, the plurality of speakers can be connected to the serial audio signal circuit SAC through a single series wire or at least two parallel wires.
