MLC 104 Plus Brushed Aluminum 60-1014-04 Retired

This product has been retired.

The Extron MLC 104 Plus MediaLink┬« Controller is an easy-to-use control panel for any small classroom or meeting room. The MLC 104 Plus standardizes the control interface for all systems, making AV systems simple to use. Standardization also makes setup and maintenance easier to support.  The flexible MLC 104 Plus acts as an extended remote control panel by communicating via IR or bidirectional RS-232 to control power, input selection, and volume settings with virtually any display device.  Three configurable digital I/O ports are available for interfacing with a variety of room devices, such as sensors, switches, LEDs, and relays. The MLC 104 Plus incorporates a two-gang, brushed aluminum faceplate for a professional and attractive addition to any decor.

The MLC 104 Plus is also capable of learning IR commands for centralized control of external source devices, such as DVD players and VCRs, when used with an optional IRCM - Infrared Control Module.

The MLC 104 Plus is housed in a secure two-gang enclosure which is especially vital for high traffic areas. It has the same look and functionality regardless of where it is mounted: a lectern, desk, wall, rack, or wall box.

Easy System Configuration using Global Configurator Software

The MLC 104 Plus can be fully configured using Extron's Global Configurator software. Extron creates and administers a wide selection of drivers for use with the MLC 104 Plus. Drivers enable the MLC 104 Plus to control basic display functions such as power, input selection, and volume adjustment. Users can create their own drivers or go to the Extron Web site to download RS-232 or IR drivers compatible with the latest and most popular display devices.

The MLC 104 Plus is designed to work with almost every Extron switcher, including the MediaLink Switchers, which are specifically designed to complement MediaLink Controllers. MediaLink Switchers are available to accommodate a variety of video, RGBHV, and audio signals while providing unique features that expand AV system capabilities. The MLC 104 Plus can also work as a stand-alone device to control a display without the aid of a switcher.
