Abstract: An audio processing section generates at least a left-front audio signal, a right-front audio signal, a second left audio signal that is the same as a left-front audio signal, and a second right audio signal that is the same as the right-front audio signal based on a left-front audio signal and a right-front audio signal supplied from an audio selector, and outputs these signals to a main output terminal, and supplies the second left audio signal and the second right audio signal also to a switch section. When a first mode is selected, the switch section selects the audio signal from the audio processing section, and supplies it to a ZONE2 output terminal. On the other hand, when modes other than the first mode are selected, the switch section selects an audio signal from the audio selector, and supplies the selected audio signal to the ZONE2 output terminal.

Abstract: A pre-out terminal that outputs the audio signal is fixed. One of a surround back left audio signal SBL, a left outside audio signal LW, and a left upside audio signal LH is selected by a user operation, and output to a pre-out terminal 11c. A determination which one of two signals except the pre-out terminal in the signals SBL, LW, and LH is included in multichannel audio data is made. When it is determined that the signal SBL is included, the signal SBL amplified by an amplifier 12a is supplied to an SBL speaker terminal 14a. When it is determined that the signal LW is included, the signal LW amplified by the amplifier 12a is supplied to an LW speaker terminal 14b. When it is determined that the signal LH is included, the signal LH amplified by the amplifier 12a is supplied to an LH speaker terminal 14c.

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 S13b. 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.

Abstract: A pre-out terminal that outputs a left outside audio signal can be fixed and an increase of the number of DACs is prevented. In the case that a surround back left audio signal SBL and a left outside audio signal LW are included, the signal SBL is amplified and output to a surround back left SP terminal 14a through a switch S13a. The signal LW is amplified and output to a left outside SP terminal 14b through a switch S13c. The signal LW is supplied from a DAC 11b to a left outside pre-out terminal 11d through a switch S11c. At this point, in order to supply the signal LW to the left outside pre-out terminal 11d, a DAC 11c is not used, but the DAC 11b is used. Accordingly, the DAC 11c can be used for another signal (ex., ZONE2) to decrease the number of DACs.

When the left upper audio signal is included, a switch 13d is turned ON to supply the left upper audio signal amplified by the amplifier 12b to a SP terminal 14c.
