[Problem] To enable the desired number of channels to be listened to at a lower cost and without wasting resources. [Solution] Process multi-channel digital audio signals by coordinating between a plurality of AV amp devices. An operation terminalassigns audio channels to be processed, to each AV amp device, and, on the basis of the signal processing time for each AV amp device, determines an output delay time for each AV amp deviceso that the output timing for analog audio signals matches for all AV amp devices. Each AV amp devicedecodes input digital audio signals into analog audio signals for audio channels assigned to that AV amp deviceby the operation terminaland delays the output of the decoded analog audio signal, by the output delay time for that AV amp devicedetermined by the operation terminal
