It selects one of two inputs, HDMI or USB-C, then equalizes, re-clocks and distributes that signal to eight identical HDMI outputs at up to 4K@60Hz 4:4:4 with HDCP 2.3. It is built for spaces where one presenter or media source has to reach many screens, such as large training rooms, divisible spaces, lobbies and overflow seating.\u003c\/p\u003e\u003cimg src=\"https:\/\/cdn.kramerav.com\/web\/images\/products\/zoom\/kramer-da3-28-h-pi.jpg\" alt=\"Kramer DA3-28-H 4K HDR HDMI and USB-C distribution amplifier\" style=\"max-width:100%;height:auto;\" loading=\"lazy\"\u003e\u003ch2\u003eHow does the Kramer DA3-28-H work?\u003c\/h2\u003e\u003cp\u003eEither the HDMI or USB-C input is selected, and the signal is regenerated before it is split to eight HDMI 2.0b outputs at up to 18Gbps.
