MLA VC10 Plus • Setup Guide
The Extron MLA VC10 Plus Volume Control Module converts RS-232 commands from a
control system into voltage or impedance changes to control audio amplifiers with volume
and mute control ports. The MLA VC10 Plus mutes or makes level changes on an Extron
MPA Series or half rack XTRA
™ Series amplifier from a TouchLink ™ Touchpanel system, an
RS-232-capable MediaLink ® Control Processor, or a third-party control system. The control
module also supports third-party amplifiers that use either variable voltage or 10 kilohm
potentiometer control.
This setup guide provides instructions for quick installation and configuration of the
MLA VC10 Plus with Extron products or some common third-party amplifiers. Installation
and service must be performed by experienced installers only. For complete features,
functions, and configuration instructions, read the user guides that come with your control
processor and amplifier and see the MLA VC10 Plus User Guide, which is available at
www.extron.com .
