Crestron : DMC-S-DSP
DigitalMedia 8G Fiber Input Card w/Downmixing for DM Switchers
By: Crestron
The World’s Leader for Advanced Home, Campus & Building Control Automation Solutions
Description
The DMC-S-DSP is an input card designed for use with any card-based Crestron® DigitalMedia™ Switcher. It provides one DM 8G® Fiber input, with associated HDMI® pass-through and analog audio outputs. The DM 8G Fiber input enables the connection of a DM 8G Fiber transmitter, or the output of another DM® switcher, using a single strand of multimode fiber.[1]
The DMC-S-DSP provides all the features of the DMC-S with the addition of downmixing to enable the simultaneous distribution of multichannel 7.1 surround sound and 2-channel stereo signals. It is recommended for use with surround sound sources to allow the original multichannel signal to be distributed to rooms with surround sound systems, while simultaneously distributing a 2-channel downmix signal to stereo-only rooms and devices.
Features
