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.
Installation1. 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.
