A multi-channel broadcasting system using a digital matrix amplifier performing the setting of respective equipment is provided to control the model equipment through a digital master controller. An 8-channel audio input unit 66 is electrically connected to a digital audio mixer. Sound source equipment connection terminals are electrically connected to the sound equipment. A data converter unit 46 converts each data and a contact point signal. An audio matrix IC 60 outputs an input sound source signal to an arbitrary channel. A pair of audio output terminals transmits the output signal of the audio matrix IC.
