Model Version Description Part #
MLC Plus 50 White and Black Faceplates, 2-Gang 60-1468-03

The MLC Plus 50 is an easy-to-use Ethernet controller designed for handling common AV functions, such as display on/off, input switching, volume control, and Ethernet control of AV devices. As with all controllers in the MediaLink Plus Series, it has more features and enhanced security. The faceplate hides the mounting screws and, combined with its rounded corners and beveled edges, gives the controller a refined, sleek appearance. PoE allows the MLC Plus 50 to receive power and communication over a single Ethernet cable. It mounts in a two-gang junction box, and includes black and white faceplates.

The MLC Plus 50 is configured using Extron Global Configurator Plus or Global Configurator Professional software. It also integrates seamlessly with Extron’s award-winning GlobalViewer® Enterprise software for complete AV resource monitoring, management, and control over a computer network. The MediaLink Plus family of controllers supports popular Web browsers and the Extron Control App.
