The DMC-C-DSP is an input card for a Crestron® DigitalMedia™ Switcher, providing one DM 8G+™ input. The DM 8G+ input enables the connection of a DM 8G+ Transmitter, or the output of another DM® switcher. Just one 8-conductor twisted-pair cable is required, supporting distances up to 330 feet (100 m) using CAT5e or Crestron DigitalMedia 8G™ Cable.
The DMC-C-DSP provides all of the features of the DMC-C with the addition of internal surround sound down-mixing to enable the simultaneous distribution of uncompressed 7.1 surround sound and 2-channel down-mix signals. The DMC-C-DSP is recommended for use with Blu-ray Disc® players and other HD sources that output multi-channel surround sound audio via HDMI®, allowing the multi-channel signal to reach the surround sound system without requiring any decoding, while also providing a 2-channel down-mix to feed a stereo zone or audio distribution system.
Power over DM (PoD) is available from the DM IN port of the DMC-C-DSP card to power a compatible DM 8G+ transmitter. To enable Power over DM, simply connect an 802.3af PoE source (Crestron PWE-4803RU, CEN-SW-POE-5, or equivalent) to the DMC-C-DSP's POE IN port.
Additional AV connections on the card include HDMI and stereo analog audio outputs. 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 DM input and passes it through to feed a Sonnex™, Adagio®, or other multi-room audio distribution system.
The DMC-C-DSP may also be used with the DMCI DigitalMedia Card Interface to provide a DM 8G+ receiver solution that's perfect for installation in an equipment rack or AV cart, or as a portable display interface. As a DM receiver, and as a DM switcher input card, the DMC-C-DSP enables EDID signal detection and format management, CEC device control, and audio breakaway.
