<p>When a first bi-wiring speaker is connected to output terminals 5A and 5B and a second bi-wiring speaker is connected to output terminals 5D and 5E, and further a two-channel stereo reproduction is performed, a signal 3L for a L channel outputted from a decoder 2 is amplified by amplifiers 4A and 4B in parallel to be given to the first bi-wiring speaker in a bi-wiring connecting manner and a signal 3R for a R channel outputted form the decoder 2 is amplified by amplifiers 4C and 4D in parallel and given to the second bi-wiring speaker in a bi-wiring connecting manner. At this time, a gain corrector 7 equalizes a gain which an output signal of the amplifier 4A has with respect to the signal 3L for the L channel with a gain which an output signal of the amplifier 4B has with respect to the signal 3L for the L channel. Similarly, a gain corrector 8 equalizes a gain which an output signal of the amplifier 4C has with respect to the signal 3R for the R channel with a gain which an output signal of the amplifier 4D has with respect to the signal 3R for the R channel. <IMAGE></p> |
