The Crestron DMC-4K-CO-HD is a high-performance, two-channel output card designed for the Crestron DigitalMedia modular switcher chassis, such as the DM-MD series. It provides certified HDBaseT connectivity for distributing ultra-high-definition 4K audio, video, control, and power over a single, long-run CAT cable. This card is engineered to serve as the primary output interface for connecting the central switcher to remote displays or other HDBaseT receivers in commercial and residential AV installations. It supports the latest 8G+ signal bandwidth, ensuring compatibility with 4K/UHD content at 60 Hz with 4:4:4 chroma sampling, HDR (High Dynamic Range), and HDCP 2.2 content protection, delivering a future-proof pathway for the highest quality video sources available.

Each of the card's two independent output channels converts the switcher's internal digital signal into the HDBaseT standard, which can transmit the complete AV signal, along with bidirectional RS-232 and IR control, Ethernet, and in some implementations, power (PoH - Power over HDBaseT) to compatible devices, over distances up to 100 meters on a single CAT6a cable. This dramatically simplifies system infrastructure by reducing the number of cables required between the equipment rack and the display location to just one, which also carries control signals back to the switcher for device management. The card is fully integrated into the Crestron ecosystem, allowing for seamless EDID management, automatic signal negotiation, and centralized control via Crestron's software tools, ensuring reliable operation and simplified troubleshooting.

The value of this output card lies in its ability to enable clean, centralized, and scalable AV distribution. It is a critical component for system integrators designing boardrooms, classrooms, digital signage networks, and luxury home theaters where uncompromised 4K video quality and long-distance signal transmission are required. By leveraging the HDBaseT standard within the proven DigitalMedia platform, Crestron provides a robust, standards-based solution that ensures interoperability with a wide range of third-party displays and receivers while maintaining the deep system integration and management capabilities for which Crestron is known. This card transforms the modular switcher into a powerful distribution engine, capable of driving the most demanding contemporary displays with a single, elegant cable solution.
