VCM 200 D • Installation Guide
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.
For product specifications visit www.extron.com.
NOTE: Check that the installation meets the local and state regulatory requirements,
including building, electrical, and safety codes, and UL and ADA accessibility
requirements
.
Installation
1. If the installation requires a white faceplate and knob instead
of black, change the faceplate and knob as below:
a. Turn the adjustment knob to its lowest setting
and, using the supplied hex key, turn counter-
clockwise to loosen the hex screw (see image at
right) and remove the knob.
b. Turn the device over, press the two tabs on the
underside, and push the faceplate away.
c. Snap in the desired faceplate and install the
matching knob. Secure it in place by turning
the hex screw clockwise to tighten it.
2. Connect the cables from the audio source (amplifier) location to the rear of the
VCM 200 as shown:
A = ground
B = volume and mute control with
DC voltage. The range is 0 to 10 V,
where 0 V is mute and 10 V is
maximum volume.
C = 10 VDC reference voltage
3. Mount the cabled device and attach
the Decora trim plate.
