The UHD88-EXB400R-K is a 4K HDMI Matrix extender that distributes media signals from 8 inputs to 8 distant displays. It supports video resolutions up to 4K@60Hz and 2K@60Hz and is compliant with HDMI 2.0b and HDCP 2.2 standards. This matrix extender can extend HDMI signals up to 300 feet at 4K@60Hz 4:4:4. With a video bandwidth of 18Gbps, it also allows for seamless pass-through of HDR, HDR10, HDR10+, Dolby Vision, and HLG. For displays that don't support 4K resolution, this matrix extender can downscale the resolution to 1080p for any HDBaseT output ports. This matrix extender supports a wide range of audio formats up to 7.1 channels, including LPCM, Dolby TrueHD, and DTS-HD Master Audio, with audio de-embedding (audio extraction) through analog and coaxial outputs simultaneously. It is equipped with bi-directional IR control allowing the control of the source device from the receiver's location and vice versa. Its Power over cable technology enables powering up the setup through only one power adapter connected to the transmitter. The unit can be controlled via the front panel buttons, remote control, RS-232, LAN, or the WebGUI interface. With its rack-mounted design, integration into both residential and commercial setups becomes easy.
