QM-MD7x2

QuickMedia™ Matrix Switcher/Mixer

Applications

The MD7x2 is part of the Crestron MediaManager line of integrated presentation
solutions. It is ideally suited to work with Crestron’s MediaManager distribution
systems, wall plate media centers, FlipTop media centers, receivers and control
processors to allow quick switching of multiple A/V sources in a presentation
system. MediaManager devices are designed for conference room, auditorium, and
lecture hall applications, or anywhere else where audio, video, or computer
equipment needs to be easily connected and disconnected from a presentation system
or room control system.

The following diagram shows an MD7x2 in a lectern application.
