<P>PROBLEM TO BE SOLVED: To provide a multichannel audio amplifier which can finely adjust settings for a sound field, depending on a movement of a user. <P>SOLUTION: The multichannel audio amplifier includes: an audio signal obtaining section which reproduces or receives audio signals of multiple channels; a loudspeaker connection section to which loudspeakers of the multiple channels are connected; and a signal processing section which adjusts the timing of outputting an audio signal of each channel and outputs the audio signals from the loudspeaker connection section so that the audio signals of the multiple channels simultaneously reach a predetermined listening point. The signal processing section detects a displacement between a position of the listener and the listening point, and based on this displacement, modifies the audio signal outputting timing. <P>COPYRIGHT: (C)2011,JPO&INPIT |
