Quad Lopass Gate Model 292t

Four low pass gates after Don Buchla's 292, part of the Buchla & Tiptop Audio 200t series, made under licence from Buchla. Each is a vactrol-controlled filter and amplifier.

Key features

• A three-way switch per channel: linear gate, lowpass filter, or a combination of both
• The lowpass mode keeps the vactrol's natural decay (the "snap" when pinged)
• A control voltage input and a manual offset knob per channel
• The four outputs also summed to a mono mix
