The VR 2 provides a simple "pot-on-a-wall" solution to adjust volume from a remote location for products having 0-5 VDC level inputs. The VR 2 fits in a standard US electrical box and can be paired with a DecoraT plate.
It contains a linear taper potentiometer with a single Euroblock screw terminal for each of the pot's three conductors, the Vr terminal, the Vc wiper terminal, and the ground terminal. It is compatible with these units:
