VCA

Simple VCA with two attenuated CV inputs

VCA is a simple Voltage Controlled Amplifier with two CV Inputs. Both Inputs can be used at the same time to have Volume Control over the other CV signal.

Each CV signal may be attenuated with a potentiometer. The Volume potentiometer will decrease or increase the volume of the audio signal being fed into the input Jack. 

An LED is indicating the current volume.
