The Crestron DM-RMC-100-1 is a compact receiver and integrated room controller that forms the user-end component of a Crestron DigitalMedia system. Designed for installation in or near a display in a conference room, classroom, or home theater, its primary function is to receive high-definition audio, video, control, and Ethernet signals transmitted over a single CATx cable (Category 5e/6/7) from a centrally located DigitalMedia transmitter or matrix switcher. This receiver decodes the DigitalMedia stream, outputting video via HDMI or DVI, audio to speakers or an external sound system, and restoring Ethernet connectivity for the local display or other peripherals. Its integrated design simplifies installations by consolidating signal reception and room control into one discreet device, reducing rack space and cable complexity at the display location.

Beyond signal reception, the "RMC" designation signifies its role as a Room Controller, embedding a powerful control processor within the unit. This allows it to directly manage room functions such as lighting, shades, and AV equipment via its built-in control ports (IR, serial, relay, and digital I/O) without requiring a separate control system processor in the room. The receiver can be programmed using Crestron's software tools to create a customized, intuitive user interface accessible via connected touch panels, tablets, or the provided simple front-panel buttons. This dual functionality makes it an efficient all-in-one solution for smaller rooms or as a scalable endpoint in larger systems.

The DM-RMC-100-1 is engineered for professional, reliable operation in commercial environments. It supports high-resolution video up to 1080p and multi-channel digital audio, ensuring high-quality presentation and multimedia playback. Power is typically supplied via Power over HDBaseT (PoH) from the connected transmitter, eliminating the need for a local power outlet. By combining high-performance AV distribution with local control processing in a single, streamlined device, Crestron provides integrators with a highly effective tool for creating manageable, user-friendly, and feature-rich AV presentation spaces.
