2-channel non-powered VCA module with a unique core.
Dual Opto-Gate
At the heart of this module is the ILCT-6 2-channel opto-isolator. Full analog gating with nothing to get in the way of your signal. Inputs can be audio signals OR CV control signals. This little wonder can gate well into the audio range allowing some simple frequency modulation. Gating signals can come from an LFO, envelope, or sequencer.
Non-Powered - 6hp (30mm)
