ABSTRACT:
An augmentation amplifier includes a first power amplifier stage having an output adapted to be coupled to one side of a load. A second amplifier of negative unity gain has an output coupled to the input adapted to be of the first amplifier and its input coupled to the other side of the load. The circuit may be switched to bypass the bridge and modular units may be employed together. The system is particularly adapted for a powered speaker system for use with a computer sound card.
