1. INTRODUCTION
This 8 by 8 Matrix provides the ability to connect up to eight 4K
UHD HDMI sources to up to eight 4K UHD HDMI displays and freely
switch between them. This unit comes with full support for 18Gbps
(600Mhz) resolutions up to, and including 4K@60Hz (4:4:4, 8-bit) as
well as support for 16-bit Deep Color up to 1080p@60Hz, HDR (High
Dynamic Range), HD audio and other features dened by the HDMI
2.0a specication. With a comprehensive EDID management feature
that includes the ability to select between built in default EDID, EDID
copied from connected sink devices, as well as a congurable EDID,
this matrix can solve many interconnectivity problems.
This unit also features eight USB ports which supply up to 5V/1A power
for use with connected AOC (Active Optical Cable) ber cable
extenders. By using these specialized cables your HDMI content
can be extended much further than would be possible with normal
HDMI cables. The built-in OSD has the ability to display user editable
general information text so each output can display up to 2 lines of
customized text on top of the video source in the color of your choice.
This unit provides an intuitive set of front panel controls with an LCD as
well as RS-232, Telnet, WebGUI, and IR remote control options.
