VCM 100 AAP
Volume/Mute Controller
(mounted in an Extron
AAP 100 Frame)
VCM 100 AAP and MAAP
Remote connector pin configuration
As shown below right, Pin 1 is a 10 VDC reference voltage. Pin 2 is volume and mute
control with DC voltage; the range is 0 to 10 V, where 0 V is mute and 10 V provides
maximum volume. Pin 3 is ground.
All nominal levels are at ±10%.
The Extron VCM 100 AAP and VCM 100 MAAP are remote volume/mute controllers
designed to work with Extron products (such as the MPA 122 mini power amplifier).
Mounted into standard Extron AAP or MAAP mounting frames, the VCM 100 AAP and
VCM 100 MAAP each have a 10k ohm potentiometer volume control knob and mute
button.
The Mute button toggles between mute and un-mute, turning bright red to indicate
mute, and dim green to indicate un-mute.
Audio level setting procedure
To set the system level to not exceed the maximum
volume in using the VCM 100, do the following:
1. Reduce the power amplifier volume to minimum.
2. Turn the Volume knob on the VCM 100 to the
maximum position.
3. Slowly turn up the power amplifier volume to the
maximum undistorted sound level allowed for the
application.
