MSRP $6999.00


The BG-UM88-100M-KIT is an eight input 4K HDMI matrix with eight HDBaseT outputs. With Ethernet passthrough for all receivers, bi-directional IR passthrough, and full audio matrix functionality, this powerful switcher provides system-wide routing, control, and management from a single centralized unit.

HDBaseT technology allows an uncompressed HDMI signal to be transmitted over a category 6 cable at distances up to 100 meters (328 feet). When combined with the eight mirrored HDMI outputs, this allows the BG-UM88-100M-KIT to send [email protected] 4:4:4 video to sixteen displays.

Connectivity & Features

The BG-UM88-100M-KIT supports resolutions up to [email protected] 4:4:4. The HDMI 2.0 ports are HDCP 2.2 compliant and transmit video at speeds up to 18Gbps while supporting Dolby Vision, HDR10+, and HLG formats. With the HDBaseT outputs, [email protected] 4:4:4 video signals can be extended to distances of up to 328 feet (100 meters) over a single Category 6 cable. Each output performs 4K to 1080p downscaling and supports ARC (Audio Return Channel). With 24V power over cable on all HDBaseT outputs, the BG-UM88-100M-KIT supplies power to each HDBaseT receiver, each containing dual LAN ports.

Full audio matrix functionality is possible with the BG-UM88-100M-KIT. This allows users to select any of the HDMI, ARC, 3.5mm, optical, or coaxial audio sources and assign them to any of the HDMI, 3.5mm, or coaxial outputs. Two 3.5mm stereo, one optical, and one coaxial audio input ports provide audio embedding from external sources. Audio de-embedding is available from all eight HDMI sources via analog audio (3.5 mm stereo) and digital coaxial audio outputs.


The BG-UM88-100M-KIT can be operated via the front panel menu, IR remote control, RS-232, or a detailed web interface. Bi-directional IR control is supported along with full IR matrix functionality. Smart EDID management via the front panel menu and web interface eliminate HDMI handshake issues for fast and reliable input switching. With bi-directional IR passthrough, RS-232 passthrough, and dual ethernet connections on each HDBaseT receiver, this powerful unit provides a centralized backbone for system-wide control and connectivity.
