Buchla 292e Quad Dynamics Manager

The 292e is functionally identical to the original 292, with the addition Velocity control and parameter storage.

The 292e Quad Dynamics Manager is functionally identical to the original 292, with the addition of two new features: Velocity control and parameter storage.

The 292e sports four independent voltage-controlled amplifiers. Each has a signal input and output, a control voltage input that varies the unit’s gain from -120dB to 3dB, an offset adjustment, and a velocity input. The latter adds further control to the gain when employed and is transparent when unconnected.

A switch selects one of three operating modes: straight gate (VCA), lowpass filter (VCF), or a combination of the two, in which the spectral response varies as the gain is changed.

Frequency domain gating imparts a dynamic tonal variation that gives the listener a sense of absolute loudness. This quality is characteristic of all acoustic instruments (the harder you strike, pluck, or blow, the richer the overtone structure). A mix of the four output signals is also provided.

The settings of the 292e can be stored and recalled using the 225e or 206e Preset Manager.
