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). Power over DM (PoDM) is supplied over the same 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 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.

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[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.

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.
