HD Matrix Switcher:
The DM-MD6X6 provides six HDMI inputs to handle HDTV receivers, DVD or Blu-ray Disc players, media servers, computers, and other HD digital sources. Outputs include one HDMI and five DigitalMedia ports, furnishing simple one-wire connectivity for a local display or audio processor, and five additional displays anywhere in the house. QuickSwitch HD matrix switching allows any display to view any source at any time.
Crestron exclusive DM 8G+ technology affords the ultimate in simplicity, providing a true one-wire interface for distributing high-definition video, audio, and control signals to multiple displays throughout a residence or commercial structure. Simply connect a DM 8G+ receiver at each flat-panel display or projector for a complete AV and control interface. Just one CAT5e wire run to each receiver transports pure, uncompressed HD video, 7.1 surround sound audio, 10/100 Ethernet, and control signals for a fully integrated media system with minimal wiring. DM 8G+ allows for wire runs up to 330 feet (100 meters) using CAT5e or Crestron DigitalMedia 8G Cable.
