2VCA contains two separate VCA (voltage controlled amplifiers); the classic module to shape the volume of a sound that is fed to IN by a control voltage, e.g. from an ENV to the CV input.
A switch determines the operation mode (DC/CV or audio), choosing the right position can reduce/avoid pop's with short attack envelopes.
An additional knob for each VCA attenuates the level, if necessary.
