DMC-S2 is an input card for a Crestron DigitalMedia switcher, providing one DigitalMedia 8G single-mode fiber (DM 8G SMF) input. The DM 8G SMF input allows one DM switcher to receive a DM 8G signal from another DM switcher located in a separate room or building. Just one single-mode fiber optic strand is required, supporting distances up to 7.5 miles (12km) using CresFiber 8G SM or G.652.D single-mode fiber. Additional AV connections on card include HDMI and stereo analog audio outputs. The HDMI output simply 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 DM input and passes it through to feed a Sonnex, Adagio, or other multi-room audio distribution system. DMC-S2 may also be used with the DMCI DigitalMedia card interface to provide a compact DM 8G SMF receiver solution in lieu of a switcher. As a DM 8G SMF receiver, and as a DM switcher input card, the DMC-S2 enables EDID signal detection and format management, CEC device control, and audio breakaway.
