Quad VCA

Quad VCA / VC-Mix

The Quad VCA/VC MIX is configured as 4 separate VCA or as a VC mixer or both.

The VCA's are high quality analogue with low noise and low CV breakthrough. If the output socket of any VCA channel is unused then that signal will be mixed with the output of the final channel.
However, any VCA channel can simply be taken out of the mixing process by inserting a jack lead into its respective output socket.The first VCA can simply be taken out of the mixing process by inserting a jack lead into its respective output socket.

Each VCA has two controls.
•Firstly, there is GAIN, a fixed bias to set the initial gain of the VCA, it can also be used a volume control.
•Secondly, the CV pot allows you to alter the sensitivity of the external CV that controls the VCA's gain. The pot is a 'reversible attenuator, so you are able to control not only the depth of the modulation but also the polarity. With the CV pot set straight up no CV signal reaches the VCA. With it fully right the CV is applied so that positive CVs increase the gain of the VCA. With the pot fully left then increasing positive CVs reduce the gain of the VCA.

Each VCA can be either direct coupled (DC) or high pass filtered (AC). The former allows DC and low frequency signals to be processed. While the latter provides a DC block to process only alternating audio frequencies.
