ABSTRACT:
A method and apparatus for generating a plurality of audio outputs from first and second stereophonically related audio signals includes coupling the first audio signal out as a leftmost audio output channel, coupling the second signal out as a rightmost audio output channel, and coupling said first and second signals to one or more mixers, each said mixer acting to combine a predetermined portion of said first signal with a predetermined portion of said second signal, and one or more amplifiers, each operatively connected to the output of a respective mixer, for amplifying said combined signal from said prospective mixer such that an intermediate audio output channel is generated by each said amplifier thereby.
