Abstract: Problem: To provide a device which can suppress temperature rising at low cost. Solution: An AV amplifier 1 includes a volume circuit 4, a tone control circuit 5, a power amplifier 6 which amplifies an audio signal which is output from the volume circuit 4, and a microcomputer 2. When level of the audio signal is not less than a predetermined threshold, the microcomputer 2 increases gain of the audio signal to not less than maximum input voltage of the tone control circuit 5 by the volume circuit 4 and outputs the audio signal in which gain is increased to the tone control circuit 5. Further, the microcomputer 2 decreases gain of the audio signal which is output from the volume circuit 4 by the tone control circuit 5 and outputs the audio signal in which gain is decreased to the volume circuit 4.

Abstract: A ZONE4 left audio signal Z4L is output without releasing a connection of a surround left speaker SSL.
When determining that a playback of the ZONE4 left audio signal Z4L is set by a user manipulation, a controller 2 controls switches S11b and S13b in an on state, and controls switches S11a, S13a, and S13c in an off state. Accordingly, the ZONE4 left audio signal Z4L is supplied from a DSP to an amplifier 12a through the switch S11b, amplified by the amplifier 12a, and supplied to a surround back left/ZONE4 left SP terminal 14b through the switch S 13b. A surround left SP terminal 14a is an output terminal dedicated to a surround left audio signal, so that the ZONE4 left audio signal Z4L can be output without releasing the connection of the surround left speaker SSL.
