PROBLEM TO BE SOLVED: To reduce an unintended gap in the output timing of audio signals in the case of reproducing a single piece of acoustic content by the use of a plurality of AV amplifiers each connected with a speaker.SOLUTION: A control section 11a of an AV amplifier 4a decides delay times of a delay process ZXa and a delay process ZXb such that the timing when an audio signal input from an audio signal generation device 3 is output to a speaker 1C, a speaker 1L, a speaker 1R and a subwoofer 1SW via a decoding process ZD by a DSP 15a and an acoustic process ZEa and the delay process ZXa by a DSP 16a is the same as the timing when the signal is output to an AV amplifier 4b after the decoding process ZD and the delay process ZXb by the DSP 15a and then output to a speaker 1LS and a speaker 1RS via an acoustic process ZEb by a DSP 16b. |
