    en.wikipedia.org/wiki/Compressed_air_gramophone

    A pneumatic amplifier was realised by using a sensitive valve, which required little force to operate, to modulate the flow of a stream of compressed air.The basic principle of the valves used in these devices was to pass the stream of compressed air through two partially overlapping combs.

    A U.S. patent for a circlotron High Fidelity Audio Amplifier was filed by Alpha Wiggins of Electro-Voice on March 1, 1954, and granted March 28, 1958. [1] However, other inventors filed the same concept earlier: [2] C. T. Hall filed Parallel Opposed Power Amplifiers on June 7, 1951; U.S. Patent 2,705,265 was granted on March 29, 1955.

    The amplifier damping factor, which is the ratio of the nominal load impedance (driver voice coil) to amplifier output impedance, is adequate in either case for well-designed solid state amplifiers. Tube amplifiers have sufficiently higher output impedances that they normally included multi-tap output transformers to better match to the driver ...

  7. Sound reinforcement system - Wikipedia

    en.wikipedia.org/wiki/Sound_reinforcement_system

    Standards bodies differ in their recommendations for nominal level and headroom. Selecting amplifiers with enough headroom helps to ensure that the signal will remain clean and undistorted. Like most sound reinforcement equipment, professional power amplifiers are typically designed to be mounted within standard 19-inch racks.
