Audio processing apparatus
First Claim
1. An audio processing apparatus comprising:
- a first amplifier that amplifies a surround audio signal or a fourth room audio signal, the surround audio signal being a surround left audio signal or a surround right audio signal, and the fourth room audio signal being a fourth room left audio signal or a fourth room right audio signal;
a second amplifier;
a third amplifier;
a first speaker terminal that outputs the surround audio signal;
a second speaker terminal that outputs a first extended audio signal or the fourth room audio signal, the first extended audio signal being a first extended left audio signal or a first extended right audio signal;
a third speaker terminal that outputs a second extended audio signal or a second room audio signal, the second extended audio signal being a second extended left audio signal or a second extended right audio signal, and the second room audio signal being a second room left audio signal or a second room right audio signal;
a fourth speaker terminal that outputs a third extended audio signal or a third room audio signal, the third extended audio signal being a third extended left audio signal or a third extended right audio signal, and the third room audio signal being a third room left audio signal or a third room right audio signal;
a first switch that switches whether the surround audio signal from the first amplifier is supplied to the first speaker terminal;
a second switch that switches whether the fourth room audio signal from the first amplifier is supplied to the second speaker terminal;
a third switch that switches whether the amplified first extended audio signal is supplied to the second speaker terminal;
a fourth switch that switches whether the amplified second extended audio signal or the amplified second room audio signal is supplied to the third speaker terminal;
a fifth switch that switches whether the amplified third extended audio signal or the amplified third room audio signal is supplied to the fourth speaker terminal; and
a switching controller that controls the first switch, the second switch, the third switch, the fourth switch, and the fifth switch.

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.
