The Crestron DMC-4K-C is a modular HDBaseT input card designed for use within Crestron DigitalMedia™ modular matrix switchers. It allows high-resolution digital video and audio signals to be received over a single twisted-pair cable from remote transmitters, making it ideal for large-scale professional AV systems deployed in corporate campuses, universities, command centers, and high-end commercial facilities. By integrating directly into the DigitalMedia chassis, the card enables system designers to build scalable, slot-based switching architectures that can be customized per project requirements while maintaining consistent signal quality and system reliability.

Supporting 4K video transport within the DigitalMedia 8G+ ecosystem, the DMC-4K-C is engineered for environments where signal integrity, long-distance transmission, and centralized switching are critical. One of its key functional features is audio downmixing, which allows multi-channel digital audio to be converted into two-channel stereo when required by downstream devices or zones. This makes the card particularly useful in mixed-audio environments where both surround-capable and stereo-only endpoints coexist. Designed for permanent installations, the DMC-4K-C emphasizes interoperability, rack-level serviceability, and dependable long-term operation within enterprise AV infrastructures.
