The DMC-HDO is an output card designed for use with any card-based Crestron® DigitalMedia™ Switcher. It provides two independent HDMI® outputs with complementary balanced analog stereo audio outputs. The HDMI outputs are each capable of handling video resolutions up to Full HD 1080p, as well as computer resolutions up to WUXGA. DVI signals are also supported using HDMI-to-DVI adapters or interface cables.
Each HDMI output on the DMC-HDO is accompanied by a balanced analog audio output, allowing stereo audio signals to be extracted from the digital stream and fed to a sound system. The output volume is adjustable via a control system using a keypad, touch screen, handheld remote, or mobile device.
DigitalMedia offers an alternative to conventional RS-232 and IR display control by harnessing the CEC (Consumer Electronics Control) signal embedded in HDMI. Through its connection to a control system (via the DM switcher), the DMC-HDO provides a gateway for controlling display devices right through their HDMI connections, potentially eliminating the need for any dedicated control wires or IR emitters.
To configure a DM switcher complete with input and output cards, cables, and other peripherals, please use the online DigitalMedia Switcher Configuration Tool.
Are you upgrading an existing DM switcher that has older “multi-gang” DMCO-series output cards? Use the online Output Card Additions and Upgrades Tool to update your existing output cards and switcher to the new “single-gang” output card format.
