8 Port 4K HDMI HDBaseT Transmitter with Splitter, Local Output, Easy Scaling, IR and Serial, EVBMR-1089L can transmit uncompressed 4K HDMI with IR and serial through single CAT.6A and CAT.7 cable up to 70 meters or 1080p up to 100M. We suggest considering our HDBaseT Receiver EVBMR-110R together, then EVBMR-1089L can be a complete solution for broadcasting HDMI content to multiple destinations.    


Rextron HDBaseT Splitter Transmitter allows users to transmit uncompressed 4K video at the best quality without any compromise, and it offers a unique capability to split one uncompressed 4K HDMI input source and distribute it to eight displays and offers convenient local video output for users. 

Devices that support HDCP 1.4, ( High-Bandwidth Digital Content Production ) are more likely to be compatible with 4K UHD contents. Most of the latest Rextron HDMI KVM extenders and Video extenders support HDCP 1.4 or 2.2 and are particularly backward-compatible with the previous version. That means you can connect older sources to a new 4K TV under HD streaming with no HDCP 2.x to 1.x converter in between. Rextron video extender supports HDCP key to ensure uninterrupted video playback at all times.

Full-Duplex Data Communication between Tx & Rx via CAT.x cable connection is the cost-effective, hardware-based solution providing remote access and control for all RS-232 protocol devices with no need for any setup or configuration. RS-232 serial extension is suitable to be applied in Digital Signage, Smart Classroom, and Smart Home system.

The HDBaseT Transmitter over CAT.6A cable is ideal for public broadcasting, exhibition, retail stores, courtrooms, bus stations, lecture rooms, training facilities, and more applications. Moreover, It's easy to install, and no software or drivers are required.

Rextron has devoted to HDBaseT Alliance and developed hundreds of HDBaseT extenders. Through HDBaseT extenders, users would have a better experience of ultra-high-definition video & audio, Ethernet, controls, USB, and PoH( Power over HDBaseT ). HDBaseT extenders could transmit long-distance up to 100M (328ft) through a single cable. Even more, it can deliver up to 4K video, and we expect 8K in the near future.
