The DMC-C is an input card designed for use with any card-based Crestron® DigitalMedia™ Switcher. It provides one DM 8G+™ input, with associated HDMI® pass-through and analog audio outputs. The DM 8G+ input enables the connection of a DM 8G+ transmitter, the output of another DM® switcher, or an HDBaseT® certified source. Just one CAT5e wire is required for connection to the DM 8G+ input, supporting distances up to 330 feet (100 m).[1] Power over DM (PoDM) is supplied over the same CAT5e connection, providing a centralized power source for PoDM compatible transmitters.[2]

NOTE: Refer to model DMC-C-DSP for use with surround sound sources.

DigitalMedia 8G+™
DigitalMedia 8G+ provides a true one-wire transport for moving high-definition video, audio, power, and Ethernet over low-cost twisted-pair cable without any compression or repeaters. Engineered for ultra high-bandwidth and ultimate scalability, DM 8G+ handles uncompressed video beyond high-definition with support for Full HD 1080p, 2K, 3D, Deep Color, and HDCP. Audio capabilities include support for high-bitrate 7.1 audio formats like Dolby® TrueHD and DTS-HD Master Audio™ as well as uncompressed linear PCM. All signals are transported over one 8-conductor twisted-pair cable, supporting distances up to 330 feet (100 m) using Crestron DM 8G® Cable or CAT5e.[1]

HDBaseT® Certified
Crestron DigitalMedia 8G+ technology is designed using HDBaseT Alliance specifications, ensuring interoperability with other HDBaseT certified products. An HDBaseT compliant device can be connected directly to the DM 8G+ input on the DMC-C without requiring a DM transmitter.

HDMI® Pass-Through
Every DM switcher input card includes an HDMI output port, which can be used to pass the input signal through to a local audio processor or video monitor, or to feed a second DM switcher for output expansion purposes.

Audio Extracting
The DMC-C also includes an unbalanced analog audio output, allowing stereo audio signals to be extracted from the digital input and fed to a multiroom audio distribution system. The output volume is adjustable via a control system using a keypad, touch screen, handheld remote, or mobile device.[3]

NOTE: For applications requiring the simultaneous distribution of multichannel surround sound and 2-channel stereo audio signals, use model DMC-C-DSP.

Power over DM®
Power over DM (PoDM) and Power over HDBaseT (PoH) can be supplied through the DMC-C via its DM 8G+ input port to power a compatible DM 8G+ transmitter or HDBaseT device. To enable PoDM or PoH, simply connect a PoDM Power Supply (model DM-PSU-8 or DM-PSU-16[4]) to the POE IN port on the input card. As an alternative to a PoDM Power Supply, a Crestron PoE switch, PoE injector, or other 802.3af or 802.3at compliant PoE PSE may be used.[2]

Standalone DM 8G+ Receiver
In addition to its use as an input card for DM switchers, the DMC-C may also be used with the DMCI DigitalMedia Card Interface[4] 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.

To configure a DM switcher complete with input and output cards, cables, and other peripherals, please use the online DigitalMedia Switcher Configuration Tool.

Please refer to the DigitalMedia Resources Webpage at http://www.crestron.com/dmresources/ for additional design tools and reference documents.

Notes:

  1. The maximum cable length for DigitalMedia 8G+ (DM 8G+) or HDBaseT is 330 ft (100 m) using DM-CBL-8G DigitalMedia 8G cable, DM-CBL DigitalMedia Cable, DM-CBL-D DigitalMedia D Cable, or third-party CAT5e (or better) UTP or STP. Shielded cable and connectors are recommended to safeguard against unpredictable environmental electrical noise which may impact performance at resolutions above 1080p. Refer to the Crestron DigitalMedia Design Guide, Doc. #4546 for complete system design guidelines. DM 8G+ is compatible with HDBaseT Alliance specifications for connecting to HDBaseT compliant equipment. All wire and cables sold separately.
  2. Supplying Power over DM (PoDM) or Power over HDBaseT (PoH) via the DM IN port requires connection of the DMC-C’s POE IN port to a PoDM Power Supply (DM-PSU-8 or DM-PSU-16, sold separately) or an 802.3af or 802.3at compliant PoE PSE. Refer to the connected DM 8G+ or HDBaseT device for its PoDM or PoH capabilities and requirements.
  3. The analog stereo audio output is only active when the input source is outputting a 2-channel stereo signal. For applications using a multichannel surround sound source, use model DMC-C-DSP which provides simultaneous surround sound and stereo downmix output signals.
  4. Item(s) sold separately.
  5. DVI is supported via the HDMI output using a suitable adapter or interface cable. CBL-HD-DVI interface cable available separately.
