Zusammenfassung:	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.
