<P>PROBLEM TO BE SOLVED: To obtain an enough multichannel sound reproduction effect in a first zone, even when a part of multichannel power amplifiers for the first zone is required to be allocated to a second zone. <P>SOLUTION: In a first mode, in which the sound reproduction is not executed in the second zone, selector switches 9-1, 9-2, 10-1, 10-2 are switched to a Z1 side. In a second mode, in which the sound reproduction is executed in the second zone, the selector switches 9-1, 9-2, 10-1, 10-2 are switched to a Z2 side. In the second mode, DSP4a executes sound field correction to the main signals L, R and rear signals RL, PR so as to obtain desired sound field characteristics in the first zone. <P>COPYRIGHT: (C)2004,JPO |
