The Crestron DMC-4KZ-HD is a high-performance HDMI input card designed for installation into compatible Crestron DigitalMedia 4KZ modular switcher chassis. This card expands the switching matrix's capability by adding an input that supports the latest high-bandwidth HDMI 2.0 and HDCP 2.2 standards, enabling the seamless integration of 4K Ultra HD sources with High Dynamic Range (HDR) content into a professional AV distribution system. It accepts signals from devices such as 4K media players, gaming consoles, and computers, ensuring that the full visual fidelity, including expanded color gamuts and contrast ratios of HDR10 and HLG formats, is preserved and routed to any output within the DM system. The card handles the significant data rates required for 4K @ 60Hz with 4:4:4 chroma subsampling, providing a transparent pathway for the highest quality content.

Integration into the DigitalMedia ecosystem is a key strength of this card. Once installed in a DM 4KZ chassis, it is automatically detected and managed by the system's control software, Crestron Toolbox or DigitalMedia Designer. The card supports bidirectional communication of control signals, including RS-232 and IR, over the same DM cable run as the audio and video, allowing for centralized control of source devices. It also handles EDID management intelligently, communicating with both the source and the system to negotiate the optimal resolution and format, preventing handshake issues that can cause blank screens or resolution mismatches. This level of integration simplifies system design and ensures reliable operation in complex, multi-source environments.

The card is engineered for reliability in 24/7 commercial installations, with robust components designed to handle continuous operation. It is hot-swappable in supported chassis, allowing for maintenance or upgrades without taking the entire system offline. By providing a dedicated, high-bandwidth HDMI input with full HDR support, the Crestron DMC-4KZ-HD HDMI HDR Input Card future-proofs AV distribution systems, ensuring they can accommodate the evolving standards of source devices and deliver an exceptional viewing experience in boardrooms, classrooms, control rooms, and luxury residential settings.
