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).
CAT5e connection, providing a centralized power source for PoDM
compatible transmitters.

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 high­definition video, audio, power, and Ethernet over low-cost twisted-pair
cable without any compression or repeaters. Engineered for ultra high­bandwidth 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.

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.

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
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.

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
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.

DMC-C DigitalMedia 8G+™ Input Card for DM® Switchers

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-Cís 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.
