Quad VCA

AT1 Modular Quad VCA

AT1 Modular's Quad VCA packs four exponential VCAs into a single module, each with its own Level control and an attenuverter setting the amount and polarity of incoming CV. The CV input on channel 1 is normalled across the other three, so a single envelope or LFO can drive all four without extra patching. Certainly, this normalling can be interrupted—patch a cable into any of the other CV jacks, and the chain is broken from that point onward. Exceptionally useful in a compact size, the Quad VCA from AT1 is a great addition to any system.

Quad VCA Features

• Four exponential VCAs
• Individual Level control per channel
• Dedicated CV input per channel, each with an attenuverter for depth and polarity
• Channel 1's CV normalled across channels 2, 3, and 4, so one modulation source can drive all four
• Break normalling by patching any of the other CV jacks—the chain is interrupted from that point onward
