Crestron DMC 4KZ HD DSP

The DMC-4KZ-HD-DSP is a single HDMI input card for any card-based Crestron DigitalMedia switcher. It carries every capability of the DMC-4KZ-HD, taking 4K60 4:4:4 and HDR sources and handling Full HD 1080p, Ultra HD, 2K, and 4K signals with HDCP 2.2, HDR10, Deep Color, 3D, and high-bitrate 7.1 audio.

Its added feature is downmixing. The card can distribute a multichannel 7.1 surround signal and a 2-channel stereo signal at the same time, so the original surround feed reaches rooms with surround systems while a stereo downmix goes to stereo-only rooms and devices. That makes it the HDMI input to choose when a source carries surround audio that has to serve mixed room types. The card installs in a DM switcher chassis.
