Abstract
To enable listening with a desired number of channels at a lower cost and without wasting resources. According to the present invention, a multi-channel digital audio signal is processed through the cooperation of a plurality of AV amplifier devices. One AV amplifier device 1 serves as a master, and distributes the audio channels to be processed to the other AV amplifier devices 1 including the own device 1, and determines, on the basis of the signal processing time of each AV amplifier device 1, the output delay time of each AV amplifier device 1 such that the output timings of the analog audio signals of all AV amplifier devices 1 match each other. Then, the AV amplifier device 1 decodes the input digital audio signal into an analog audio signal for an audio channel distributed to the own device 1 by the master, and delays and outputs the decoded analog audio signal by the output delay time of the own device 1 determined by the master.
