Abstract
The output voltage of the output of a power supply for providing power to an audio amplification and transduction system having a plurality of channels with each channel transmitting an audio signal includes monitoring the amplitude of the audio signals and providing a highest amplitude signal representative of the contemporary highest amplitude of the audio. AC electrical power has a variable frequency controlled by the highest amplitude signal and is converted to DC voltage having the output voltage related to the variable frequency. This DC voltage is delivered to the channels.
