ABSTRACT:
A power supply controlled stereophonic amplifier system of a simplified circuit configuration which includes an analog logic circuit that generates a larger one of the input signals for left and right channels thereby to control the output voltage of the DC-DC converter as a power supply by means of a pulse train of pulse widths that change according to the output of the logic circuit. The output of the analog logic circuit is compressed by a signal compression means which functions to compensate for the non linear response of the DC-DC converter.
