Remote control options
The MP 101 has three remote control options:
1. The Extron VCM 100 volume/mute controller and
VC 50
volume controller use a 10 k ohm potentiometer as
the main method for controlling volume levels.
The VCM 100 includes an illuminated Mute button and
operates in sync with the MP 101 AAP.
2. The Extron MLA-VC10 converts RS-232 serial command
to 0~10 volt variable DC for volume control.
3. Generic volume/mute controllers are standard 10 k ohm
potentiometers.
