A multi-channel audio reproducing apparatus includes several audio power amplifiers, the number of which is less than the number of channels required for the multi-channel format of the input audio signals. The multichannel audio reproducing apparatus also includes a decoder for decoding input audio signals and a signal processor, arranged between the decoder and the audio power amplifiers, for receiving decoder output signals of a plurality of channels of the multi-channel format at the input channels thereof and for outputting, at the output channels thereof, audio signals of channels of a number less than the number of audio power amplifiers. A controller controls the signal processor in response to setting information of the connection and installation of a plurality of speakers to which the outputs of the audio power amplifiers are respectively supplied.
