Analog Engines

THAT Corporation's Analog Engines combine in one IC all the active circuitry needed to construct a wide range of dynamics processors. Each Engine includes a high-performance, exponentially-controlled VCA, and a log-responding rms-level sensor, and additional op amps and circuitry depending on model.

Whether you're designing an analog compressor, limiter, ducker, gate, de-esser, automatic mic mixer, noise reduction...or something totally unique... you will find the THAT 43xx series to be versatile, predictable, and easy to use.
