Audio Transmission Systems

Abstract

Audio transmission systems are the means by which audio signals are routed, processed, and assigned to the desired monitor and recording output channels. In the early days of electrical recording, rarely more than one or two microphones were used, and the signal routing was to a single output channel. (The terms “line out” and output bus’ are also used and refer to the main signal outputs of the control system.) The system was indeed a simple one, probably no more than an array of volume controls, or faders, some kind of metering, and perhaps a few switches for routing signals to different recording devices. Audio transmission systems used in the motion picture industry were more complex from their inception because of the necessity of recording dialogue, sound effects, and music at different times. In a sense, this represented the beginning of multichannel recording even though the final product was a monophonic one.
