8X8 4K UHD 18Gpbs HDMI and HDBaseT Matrix Switch with Bi-directional IR/Advance EDID and Downscaling

MSRP: $3,999.00

MSRP $3999.00


This HDMI matrix extender can connect eight HDMI sources to sixteen output displays. This is accomplished using four HDMI outputs mirrored to four HDBaseT outputs that run simultaneously. The HDBaseT output allows video signals to be extended to longer ranges than a standard HDMI cable. When using 1080p resolution, the signal can travel up to 492ft / 150m and 394ft / 120m at 4K.


The maximum resolution of this matrix is [email protected] (YUV 4:4:4) on all HDMI and HDBaseT ports. Data transmission is lossless and uncompressed, having a maximum bandwidth of 18Gbps, ensuring pure signal transfer for maximum image quality. The BG-UM88-150L-KIT utilizes HDMI 2.0b. The device is also HDCP 2.2 and HDCP 1.x compliant. 

Operators also have the ability to downscale video from 4K to 1080p if necessary for each output port. Power over cable is supported on all HDBaseT ports, eliminating the need for an external power supply at the HDBaseT receiver.

HDMI audio pass-through allows operators to handle high quality sound up to 7.1 CH HD audio. Various audio codecs are also supported, including LPCM, Dolby TrueHD, and DTS-HD Master Audio. Audio can be de-embedded from the unit as well via analog and digital coax ports.


The BG-UM88-150L-KIT can be controlled via buttons on the front panel, an IR remote, RS-232, LAN, and a web GUI. Advanced EDID management and CEC control are also available with this matrix. Bi-directional IR matrix routing is also supported, ensuring simple remote control of the currently selected video source as well as remote control of displays from the source location.
