The DMC-HD is an input card for a Crestron® DigitalMedia™ Switcher, providing one HDMI® input. The DMC-HD supports HDMI with HDCP, Deep Color and 3D, handling 1080p60 HDTV and WUXGA computer resolutions, and multi-channel HD lossless audio - all through a single HDMI cable. The HDMI input can also handle DVI and DisplayPort Multimode signals using an appropriate adapter or dongle.
Additional connections on the card include HDMI and stereo analog audio outputs, and a USB HID device port. The HDMI output simply passes the input signal through to feed a local device, or to feed a second DM switcher for output expansion purposes. The analog audio output, which features programmable volume control, breaks out the stereo audio signal from the HDMI input and passes it through to feed a Sonnex™, Adagio®, or other multi-room audio distribution system.
NOTE: For applications requiring the simultaneous distribution of surround sound and 2-channel audio signals, use model DMC-HD-DSP.
The USB HID port connects to the source device (i.e. computer or media server) at the central equipment rack, allowing it to be controlled by a mouse or keyboard located in another room, or at a presentation lectern, conference table, or some other remote location.
The DMC-HD may also be used with the DMCI DigitalMedia Card Interface to create a very handy problem-solving tool with many useful functions. For instance, it can be used to extract an analog audio signal from an HDMI or DisplayPort Multimode stream. As part of a complete Crestron control system, it can be used to detect and manage EDID and input source format information, to enable CEC device control, to assess a device's HDCP capabilities, and to extend a USB HID mouse/keyboard signal over Ethernet.
