Buchla model 292e Quad Dynamics Manager


Buchla & Associates

The Model 292e Quad Dynamics Manager is functionally identical to the original 292, with the exception of two new features - the 292e has velocity inputs, allowing controllers to control note volumes with performance gestures. And its settings can be stored as a part of a 200e series preset.

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 -120 to +3db, and offset adjustment, and a velocity input. The latter adds further control to the gain when employed and becomes 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. Aided by the model 225e preset manager, the settings of the 292e can be stored and retrieved.
