Red
This guide provides instructions for an experienced installer to
install an Extron VCM 200 D Remote Volume Controller.
The VCM 200 D is a remote volume/mute controller with a
10k ohm potentiometer. It is designed to work solely with any
Extron amplifier product with a remote volume control port, such
as the MPA 122 or MPA 401 Mini Power Amplifiers.
The VCM 200 D is shipped assembled in black, and mounts into a
mud ring (supplied) or a junction box (not supplied) and is finished
by a Decora®-style trim plate.
A white trim, bezel, and knob are also included.
