DMC-CAT DM CAT Input

Card for DM Switchers

The DMC-CAT is an input card for a DigitalMedia switcher, providing one

CAT-type DM input. The DM CAT input enables the connection of a DM

transmitter or the output of another DM switcher, with a potential cable length up to

450 feet (137 m) using DigitalMedia cable.

NOTE: For optimum performance, Crestron recommends Crestron DigitalMedia

cable.

Additional connections on the card include both HDMI and stereo analog audio

loopback outputs. The HDMI output 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 HDMI input and passes it through to feed a CNX-PAD8A,

AAE, or other multi-room audio distribution system.

NOTE: For applications requiring the simultaneous distribution of surround sound

and 2-channel audio signals, use model DMC-CAT-DSP.
