4K/UHD 4-Output HDMI to
HDBaseT Distribution Amplifier
AT-UHD-CAT-4
The Atlona AT-UHD-CAT-4 is a 4K/UHD HDMI to HDBaseT™ distribution amplifier featuring pass-through
HDMI input connections, four HDBaseT outputs and display control capability. Each output transmits AV
and control signals up to 230 ft. (70 m) @ 1080p and 130 ft. (40 m) @ 4K/UHD. Features include 4K/UHD
@ 60 Hz with 4:2:0 color subsampling, HDCP 2.2 compliance, EDID management, and PoE for powering
remote receivers. A wide variety of consumer and commercial displays may be controlled by the AT-UHDCAT-4 using CEC, IR, or RS-232. Designed for commercial distribution applications, the AT-UHD-CAT-4
is control system-friendly and integrates with any TCP/IP, RS-232, or IR control system and features a 1U,
half-rack width enclosure with external, international power supply. Compatible Atlona receiver: AT-UHDEX-70C-RX.
Signal distribution applications increasingly require compatibility with HDCP 2.2, 4K/UHD @ 60 Hz support
with 4:2:0 color subsampling to ensure images reach displays with compatible copy protection and with
the pristine digital image quality of the original signal, without artifacts resulting from inferior image
distribution systems. HDBaseT distribution ensures reliable, long-distance transmission of high resolution
audio and video signals. These core features along with added display control provide additional flexibility.
Power over Ethernet not only provides compatibility with Atlona Extender products but enables HDBaseT
Certification.
Four HDBaseT outputs with transmission of AV and
control signals and PoE -
• Long distance, 230 foot (70 m) outputs offer
bidirectional extension of both RS-232 and IR
control plus remote receiver power
Compatible Atlona receiver: AT-UHD-EX-70C-RX
• Reduces multiple, separate cable runs down to
a single category cable per display, shrinking cable
bundles and required conduit capacity to reduce
cost of installation
Display control -
• CEC, IR or RS-232 control signals transmitted over
HDBaseT
• Enables control of a wide variety of displays
including commercial or low-cost consumer displays
HDMI distribution amplifier with built-in HDBaseT
transmission -
• Combines signal distribution and long distance
transmission into a single enclosure; eliminates
several devices and power supplies
• Reduces overall system costs, speeds installation,
and prevents compatibility issues
4K/UHD capability with HDCP 2.2 copy protection -
• Compatible with ultra-high definition sources and
displays; adheres to latest content protection
specification
• Ensures AV distribution systems are ready for 4K/
UHD streaming services and playback devices
