Extron electronic Universal Remote VC 50 User Manual

VC 50  
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.
