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.

Key Features

  • 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
