Volume Control Module MLA VC10 Plus

Extron MLA VC10 Plus, Digital volume control, Vrijstaand, Grijs, 241 mm, 185 mm, 68 mm

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. The MLA VC 10 Plus can be powered by an optional power supply, or from the power supply used for a MediaLink Controller or IPL Series Ethernet Control Interface.

Commercial power amplifiers with volume and mute control capability often are not equipped for RS-232 or Ethernet control. The MLA VC10 Plus bridges the gap between these amplifiers and MediaLink and TouchLink control systems by providing a convenient means to adjust volume and muting. It offers variable voltage and resistance outputs to control volume, plus a dual mode relay port that provides contact closure for muting the amplifier.

The MLA VC10 Plus features Soft Start volume ramping which slowly increases the amplifier’s volume to the previous level when powering up or when the module is unmuted. Soft Start prevents sudden, loud bursts of sound that can damage equipment or harm the listener’s hearing. A mini USB port on the front panel provides convenient access for device configuration. LEDs on the front panel indicate power and mute status, plus relay activity to facilitate setup and troubleshooting. The MLA VC10 Plus also includes an Inverse Mode for amplifiers that require a decrease in control voltage or resistance in order to increase volume. For integration convenience, the control module can be configured using the included Data Viewer software.
