MLA VC10 Plus
Volume Control Module
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 is used to mute or make level changes
on an MPA Series or half rack XTRA
™
Series amplifier
from a TouchLink
™
Touchpanel system, an RS-232-
capable MediaLink
®
Controller, or other control system.
The control module also supports third-party amplifiers
that use either voltage or 10k ohm pot control. The
MLA VC10 Plus is housed in a 1U, one-eighth rack
width metal enclosure for numerous installation
options.

•
Volume and mute control for the MPA Series or half
rack XTRA
™
Series amplifiers as well as a wide
range of commercial amplifiers
• For use with MediaLink
®
Controllers with RS-232,
TouchLink
™
Touchpanel systems, and other control
systems
• Adjust amplifier volume level using voltage or
resistance control
• Ground isolated, digital circuitry prevents noise in
signal path
• Soft Start volume ramping gently restores volume
levels during power cycles and unmuting
• Selectable volume taper provides a consistent linear
or natural logarithmic feel to volume changes
• High resolution volume control range for smooth
volume changes without audible level jumps
