The Crestron DM-TX-4K-100-C-1G-W-T is a sophisticated, wall-plate mountable DigitalMedia transmitter designed to provide a clean and professional interface for source devices in modern AV installations. It is engineered to be installed within a standard single-gang electrical wall box, presenting a discreet, flush-mounted plate to the room while housing the advanced electronics needed to connect local sources to a centralized DM switcher. This transmitter accepts HDMI input from any nearby source device—such as a laptop, media player, or camera—and converts it into a DigitalMedia signal that is transmitted over a single CAT cable (up to 100 meters) back to the central DM chassis. This approach allows users to connect their devices locally at a convenient wall plate, eliminating the need for long, unsightly HDMI cables run directly to the equipment rack and maintaining a clean room aesthetic.

This model is part of Crestron's 4K-capable series, supporting ultra-high-definition video up to 4K resolution at 60 Hz with 4:4:4 chroma sampling, ensuring the highest fidelity for detailed graphics and video content. It also supports HDR (High Dynamic Range) formats and HDCP 2.2 content protection for compatibility with the latest media sources. Beyond video, the transmitter embeds digital audio from the HDMI source and can pass bidirectional control signals—including RS-232, IR, and Ethernet—over the same CAT cable. This allows a central Crestron control system to manage the connected source device remotely; for example, turning on a Blu-ray player or controlling a videoconferencing codec from a touch panel. The "T" variant often indicates it includes a built-in test pattern generator for system verification.

The value of this wall plate transmitter lies in its combination of high performance, installation flexibility, and user convenience. It empowers system integrators to create professional, scalable systems where source connectivity is distributed to the point of use while all complex switching and processing remain centralized. By using structured cabling (CAT6/6a) for the long runs, installation costs are reduced, and future upgrades are simplified. For the end-user, it provides a simple, reliable, and high-quality connection point that looks like a natural part of the room's infrastructure, supporting seamless presentation and collaboration experiences in boardrooms, classrooms, and executive suites.
