This basic building block of a modular system is indispensable. The Hungry Robot VCA provides 2 independent, high quality VCAs. These VCAs are DC coupled which means you can patch in audio sources as well as CV sources (though its primary function is for audio). As with all Hungry Robot "Modular Boxes" the VCA can be powered with a simple 9V DC, Negative Center power supply.
-CV Knobs: The two knobs are attenuators for the incoming CV inputs
-IN: Patch in an Audio signal.
-CV: Patch in an envelope, LFO, or any CV source to provide voltage controlled amplification to the incoming source
-OUT: Output of VCA
Dimensions: 4.7” x 2.6” x 1.5”
Power: 9V DC - Negative Center - 2.1mm Barrel
