Buchla Red Panel Model 110

Buchla Red Panel Model 110

The Model 110 is 4 independent transistor based voltage controlled amplifiers behind one panel.

The Model 110 is 4 independent transistor based voltage controlled amplifiers behind one panel. Each VCA (or “gate” in the original terminology) consists of an audio input with an attenuator, a CV input, and 2 outputs. The VCA’s are AC coupled – meaning that they will not pass slow (or static) control voltages.

The VCA’s are calibrated to unity (an input of a 10v peak to peak audio wave, will produce a 10v peak to peak audio wave at output) when 5v is applied to the CV input and the attenuator is at approximately the 3’oclock position.

Notes: Unlike the later (and better known) Model 292, the original low pass gate – The Model 110 is entirely transistor based (rather than vactrol based like the 292), and is much faster.
