The 2hp DC is a voltage offset generator. It creates three channels of offset voltages, each with a different output range. Great for manually controlling CV inputs through a known range or summing together with CV signals to act as a bias. With the addition of a multiple, you can control several modules at once with a single knob. Take control with DC.
