The Crestron® HD-MD-400-C-E delivers an incredibly simple and cost-effective multimedia presentation solution for classrooms and meeting spaces. It allows a laptop or mobile device (HDMI® or VGA) to be connected to one of three inputs at a table or podium, and routes the signal to a display or projector up to 230 feet (70 meters) away. An additional HDMI source can be connected at the display device location (or through an optional wall plate near the display). Fully automatic operation detects when a source is connected or disconnected at any input and turns the display on and off, alleviating the need for any control panels or remotes. Built-in scaling ensures an optimal video image for SD and HD video signals, as well as for high-res computer signals.

Benefits of Crestron HD-MD-400-C-E KIT  DM Lite – HD Scaling Auto-Switcher & HDMI® over CATx Extender: 

MHD Signal Extender

A single CAT type cable (sold separately) links the HD-MD-400-C-E transmitter and receiver together. This cable can be up to 230 feet (70 meters) in length, offering an ideal point-to-point signal extender solution for virtually any room with a single table or podium and one display device.^[1]

EDID Format Management

To ensure that every source gets displayed at its optimal resolution and format, the HD-MD-400-C-E provides comprehensive management of the EDID information that passes between the display, scaler, and source devices. Most applications require no changes to the default settings. For applications requiring custom configuration, the HD-MD-400-C-E allows for easy assessment of each device’s format and resolution capabilities, with the ability to configure signals appropriately for the most desirable and predictable behavior..

Audio De-Embedding
Its analog audio output allows the HD-MD-400-C-E to extract the stereo audio signal from digital sources to feed a sound bar, amplified speakers, or a separate sound system.
