The Extron VC 50 is a remote volume controller designed to work with the Extron PoleVault

™ 

switcher (PVS 204SA with amp), the MLP (Mic to Line Pre-amplifier), and the MPA series  

audio amplifiers (e.g. MPA 122).

Mounted into standard one-gang wall box or mud ring, the VC 50 has a rotary volume control 

knob, which provides easy adjustment and ensures precise volume levels.

Captive screw connectors on the back panel provide quick and easy connectivity.

To set the system level not to exceed the maximum volume when 

using the VC 50, do the following:
1. Reduce the power amplifier volume to minimum.
2. Turn the Volume knob on the VC 50 to the maximum position.
3. Slowly turn up the power amplifier volume to the maximum 

undistorted sound level allowed for the application.
