Abstract
Means and method of reducing the distortion or channel separation due to interference voltages between the reproduction channels in multi-channel reproduction of acoustic sounds in systems having at least two different channels are described. The steps are deriving a control voltage from the low and high interference voltages which occurs in a channel which is proportional to the magnitude of the interference voltages, and using the control voltages as an adjustment to control the distortion or channel separation. The control voltages may be derived from a single channel. The control voltages may be combined to yield a single control signal. Both equal-phase distortion and phase-opposition distortion may be suppressed.
