The Hex VCA module consists of six channels of linear VCAs. It uses the Sound Semiconductor SSI2164 chips to provide six independent channels of high fidelity, low noise amplification of audio or CV signals.
Each channel has a dedicated volume level knob that becomes a CV attenuator when the channel CV is present. In addition, a master CV input allows for level control of all six VCAs at once. The master level knob behaves the same as the individual channel level controls.
The individual channel CVs and the master CV are additive, i.e. additional different modulation sources can be applied for unique effects.
