An electronic device whose audio frequency input signals control power from a source independant of the input signal and delivers audio frequency output signals of greater amplitude with respect to current and/or voltage. The output signals characteristics are uniformly related to the input signals. It operates at frequencies of 20 kilohertzs and below. It may or may not have signal switching capabilities.
