Voltage Controlled Amplifier

Audio In jack for inputting audio signals.

Env In Jack for inputting the main gain control signal. Primarily, an Envelope Generator is patched into this jack, but other CVs can be used here for variable gain control of the VCA output.

Ext Mod jack allows for modulation sources to be input into the VCA.

Ext Mod control allows for variable control of the amount the CV effects the VCA. As the control is rotated clockwise, the modulation goes from amplitude modulation to ring modulation.

Output Level control allows for overall output level adjustment.

Main Output jack provided for sending the VCA output to another module, an amplifier or headphones. The jack is a TRS jack and will source both sides of a set of headphones.
