Atlona Launches New Generation of HDMI to HDBaseT Distribution Amplifiers

Four new AT-HDR-CAT models deliver pristine 4K/60 4:4:4 video quality with support for HDR formats and extensive integration features

SAN JOSE, Calif., January 19, 2023 – Atlona has unveiled the company’s next generation of HDMI® to HDBaseT™ distribution amplifiers, the AT-HDR-CAT series. The successor to the popular AT-UHD-CAT family, the new DA lineup delivers superior video performance including support for 4K/UHD @ 60 Hz with 4:4:4 chroma sampling plus high dynamic range (HDR) formats. Atlona will present the AT-HDR-CAT series along with other new AV innovations in stand 5J500 at the ISE 2023 exhibition in Barcelona from January 31 to February 3.

The HDR-CAT series features visually lossless compression with no latency to enable HDR and 4K/60 4:4:4 video signal extension over HDBaseT. It is ideal for a wide array of AV applications including long-distance signal distribution for hospitality and retail displays; displaying company or safety information in commercial reception areas, warehouses, and manufacturing floors; and complementing educational AV systems by replicating presentation content to multiple screens.

HDR-CAT distribution amplifiers have one HDMI input and can transmit video plus multi-channel audio, control signals, and power over their HDBaseT outputs. Four models enable systems integrators and end-customers to choose the ideal configuration for their particular output and distance requirements:

AT-HDR-CAT-2 – two HDBaseT outputs transmit up to 130 feet (40 meters) for 4K HDR content or 230 feet (70 meters) for 1080p
AT-HDR-CAT-4 – four HDBaseT outputs transmit up to 130 feet (40 meters) for 4K HDR content or 230 feet (70 meters) for 1080p
AT-HDR-CAT-8 – eight HDBaseT outputs transmit up to 130 feet (40 meters) for 4K HDR content or 230 feet (70 meters) for 1080p
AT-HDR-CAT-4ED – four extended-distance HDBaseT outputs transmit up to 330 feet (100 meters), plus Ethernet extension

“The image quality and cost-effectiveness of our new HDR-CAT distribution amplifiers make them ideal for bringing a single source to multiple output destinations over long distances,” said Marshall Simmons, Product Manager at Atlona. “Their support for the latest 4K HDR standards ensures the highest-quality video content is supplied to the displays, while their extensive integration capabilities simplify installation and ensure maximum reliability.”

All models also offer sophisticated integration capabilities including HDMI pass-through, audio de-embedding, EDID management, CEC display control, RS-232 and IR control extension, remote power for receivers, and HDBaseT link testing. In addition to supporting TCP/IP, RS-232, and IR control, they can be easily configured and managed through a built-in web interface or Atlona’s Velocity™ AV control, room scheduling and device management system.

Rounding out the enhanced distribution system, Atlona also announces that its proven AT-HDR-EX-70C-RX and AT-HDR-EX-100CEA-RX HDBaseT receivers – previously available only within the company’s popular signal extension kits – are now available separately to pair with the new HDR-CAT distribution amplifiers. These newly unbundled HDBaseT receivers can be remotely powered from the HDR-CAT’s and reliably pass 4K HDR signals from the distribution amplifier to a display. The HDR-EX-70C-RX pairs seamlessly with HDR-CAT-2, HDR-CAT-4, or HDR-CAT-8 distribution amplifiers, while the HDR-EX-100CEA-RX is the optimal companion for the extended-distance HDR-CAT-4ED.

All four HDR-CAT distribution amplifiers, the HDR-EX-70C-RX receiver, and the HDR-EX-100CEA-RX receiver are available now through Atlona’s global network of authorized channel partners.
