The rack-mountable 8x4 Matrix for HDMI sends high definition video and multichannel digital audio from any of 8 HDMI sources to any 4 Displays. The HDMI inputs consist of 4 High Definition video switches that can each accept 2 video sources. This input scheme allows up to 8 sources to be available while viewing any 4 on the output displays concurrently. The 8x4 Matrix for HDMI eliminates the need to disconnect and reconnect sources to displays. It works with Blu-Ray players, Set-Top boxes, Home Theater PCs, and game consoles that connect to an HDMI display. Any source is accessible at all times by any display by selecting it using an IR remote or an RS-232 remote control device. The Matrix comes with rack ears for mounting in a shelving system.
