Buchla 292e Quad Dynamic Manager

The Buchla 292e Quad Dynamic Manager is a four-channel voltage-controlled dynamic processor designed by Don Buchla. It is a powerful tool for sound design, allowing users to shape and control the dynamics of their audio signals. It has been used by a variety of artists, including Aphex Twin, Autechre, and Squarepusher.

The 292e Quad Dynamic Manager works by allowing users to control the amplitude of their audio signals in four independent channels. It features four independent voltage-controlled amplifiers (VCAs) with adjustable attack and release times, as well as a compressor and a limiter. The 292e also features a sidechain input, allowing users to control the dynamics of their audio signals with external signals. Additionally, the 292e has a built-in noise gate and a low-pass filter.
