OSD Audio OSD MVC-25

If you've got a 25- or 70-volt distributed audio system in your place of business, a reliable volume knob is a crucial part of the audio pipeline. This in-wall volume control from OSD works well in either case. It features a pair of "through output" terminals on the back, so you can daisy-chain it to other volume knobs without causing impedance issues. Its removable terminal block features silver-plated contacts and can handle up to 14-gauge speaker wire. Three colors of decora plates are included to help the MVC-25 blend into almost any professional environment.
