Abstract: [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 1. An operation terminal 5 assigns audio channels to be processed, to each AV amp device 1, and, on the basis of the signal processing time for each AV amp device 1, determines an output delay time for each AV amp device 1 so that the output timing for analog audio signals matches for all AV amp devices 1. Each AV amp device 1 decodes input digital audio signals into analog audio signals for audio channels assigned to that AV amp device 1 by the operation terminal 5 and delays the output of the decoded analog audio signal, by the output delay time for that AV amp device 1 determined by the operation terminal 5.

Abstract: [Problem] To enable a sound bar and a wireless speaker to be grouped and ungrouped through a simple operation. [Solution] When a user moves a controller 3 closer to a sound bar 1. the sound bar 1 reads tag information from an RFID tag 30 of the controller 3 by using an RFID tag reader 10. detects that the user has performed an operation to move the controller 3 closer to the sound bar 1, and checks a host group state.
