ABSTRACT:
A first and a second input signals, composing a stereophonic pair, are amplified in respective channels, added by adder means in a desired phase relationship, chosen between completely in phase and 180.degree. out of phase, and the sum signal thus produced is processed by a transfer bloc having a desired transfer function, and is superimposed on the signal in the first channel with opposite phase, and is then superimposed on the signal in the second channel with a 180.degree. out of phase or in phase relationship, according to whether the input signals are added respectively in phase or with opposite phase.
