Western Electric

Western Electric played a crucial role in the development of early compressor-limiters, pioneering designs that became foundational in audio engineering. Notably, the Western Electric 110A and 111C were among the first devices used to manage audio levels, ensuring consistent sound and preventing distortion in broadcasting and recording. These units featured tube-based circuitry and innovative gain control mechanisms that set the stage for modern dynamics processing. Their designs heavily influenced later iconic models like the RCA and Fairchild limiters, cementing Western Electric’s legacy in audio compression technology.

The Western Electric 110A Program Amplifier, released in 1937, was a pioneering broadcast audio compressor designed to enhance radio transmission quality and prevent over-modulation. Known as the first compressor of its kind, this amplifier delivered a 3 dB increase in average audio signal level, effectively doubling the broadcast area without needing additional transmitter power.

The Western Electric 1126C Program Operated Level Governing Amplifier was a valve-based automatic level-control system designed primarily for AM and FM broadcasting, with additional applications in recording and sound systems. Developed through research and design by Bell Telephone Laboratories, it combined a 126C Amplifier, 298A Control Panel and 20B Rectifier. Programme-controlled gain reduction, adjustable recovery time and extensive input and output attenuation allowed it to restrain peaks while maintaining higher average programme levels.
