Abstract
A multiple amplifier system comprises a sound source, a power source, an electronic crossover network for dividing an audio signal from the sound source into a plurality of frequency ranges. Each of the divided audio signal is amplified by an individual power amplifier and fed to a corresponding speaker. A superposing circuit is connected to the sound source and the power source for superposing the audio signal from the sound source and power from the power source. The superposed signal is applied to the electronic crossover network through a lead.
