<P>PROBLEM TO BE SOLVED: To provide a multichannel reproducing device which simultaneously reproduces a plurality of sources and can obtain surround-sound effect and a stereophonic effect even if the angle to a listener changes. <P>SOLUTION: An instruction on a source to be reproduced and the angle of the listener is received by an operation part 8. A control unit 7 controls an input switching part 5 whether it inputs only a signal of a source A through an analog input 2 and an A/D converter 4 or inputs the signals of the source A and a source B through a digital input 3. The inputted signal is separated into a plurality of audio signals in DSP 6 with control of the control unit 7. A plurality of the audio signals are switched and outputted in D/A converters 901 to 906 at an output switching part 11 by the control unit 7. The audio signals outputted from the D/A converters 901 to 906 are amplified in an amplifier 10, and are outputted from output terminals 101 to 106. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
