The GMSN! Pure VCA is a real workhorse module, used to control the volume or amplitude of an audio or CV signal. This is controlled either by the offset knob, or automatically using a control voltage.
The THAT2181 used in the VCA is used in high end audio kit giving excellent signal to noise ratio.
