HDMI 4x4 4K UltraHD matrix, with FST, 3DTV and 4Kx2K UltraHD support. This matrix is ​​a compact and light alternative to rack-mounted dies. Allows up to four 4K or 1080p Full HD High Definition sources to be routed to up to four Ultra HD displays. This product supports resolutions up to 4K (3840x2160@60Hz 4:2:0 or 30Hz 4:4:4) and 4K Cinema (DCI) (4096x2160@24 or 30Hz 4:4:4). It also supports Deep Color, supporting 3DTV signals and lossless audio formats such as LPCM 7.1, Dolby TrueHD and DTS-HD Master Audio. Each UltraHD source can be routed to any of the connected screens using the front panel push button controls, the included IR remote control, the RS-232 serial interface, or IP, via Telnet, UDP, and the web server interface. The top panel LEDs show the current routing status, FST mode, audio settings and EDID settings.
