| 1. A wiring device of a multi-channel speaker system that operates a plurality of speakers with different sound range signal
values by connecting a main audio body and the plurality of speakers, comprising:
a serial audio signal circuit SAC; and
audio signal separating circuits ADC that are provided in each of the plurality of speakers,
wherein the serial audio signal circuit SAC comprises:
an analog/digital converter A/D for converting a plurality of analog signals that are generated by the main audio body to
digital signals,
a multi-channel control signal synthesizer SC for synthesizing the plurality of digital signals into a single digital audio
signal,
a clock generator CG for providing a reference clock to the synthesized digital audio signal,
a digital signal synthesizer DG for synchronizing each of the digital audio signals according to the reference clock generated
by the clock generator,
a serial signal output member SO for converting the synchronized digital audio signal to a serial digital audio signal and
outputting the serial digital audio signal, and
a single wire extended from the serial signal output member SO; and
wherein the audio signal separating circuit ADC comprises:
a multi-channel separator for separating a digital signal corresponding to the reference clock generated by the clock generator
CG from the input serial digital audio signal, and
a digital/analog converter D/A for converting the separated digital signal to an analog signal.
