Product Overview

The Atlona AT-HDR-CAT-2 is a two-output 4K HDR HDBaseT distribution amplifier designed for commercial AV signal distribution applications requiring HDMI source delivery to multiple displays over category cable. With one HDMI input and two HDBaseT outputs, this 4K HDR HDMI to HDBaseT distribution amplifier transmits full 4K/UHD video at 60 Hz with 4:4:4 chroma sampling plus HDR10, HLG, and Dolby Vision support to distances of up to 130 feet (40 meters) for 4K, or 230 feet (70 meters) for 1080p. An HDMI pass-through output enables a local monitor connection alongside the two HDBaseT runs. Integration features including CEC display control, audio de-embedding, RS-232 and IR extension, and HDBaseT link testing make the AT-HDR-CAT-2 a comprehensive HDBaseT distribution amplifier for hospitality, retail, education, and corporate AV environments.

Product Description

The Atlona AT-HDR-CAT-2 is a high dynamic range distribution amplifier with one HDMI input and two HDBaseT outputs, each capable of transmitting 4K/UHD video at 60 Hz with 4:4:4 chroma sampling plus HDR formats, multi-channel audio, control signals, and power up to 130 feet (40 meters) for 4K HDR, or 230 feet (70 meters) for 1080p, over Category 6/6A cable. A local HDMI pass-through output allows connection of an on-site display without consuming an HDBaseT output, making it practical for reception desks, control rooms, or source equipment racks. The AT-HDR-CAT-2 uses visually lossless compression technology to enable HDR and 4K/60 4:4:4 signal extension over HDBaseT without visible quality degradation or added latency. CEC display control sends power on/off commands to all connected displays via the pass-through HDMI output and HDBaseT receiver HDMI outputs using the front-panel power button, IP commands, or RS-232, enabling automated display management without a separate control system. Each HDBaseT output supports bidirectional RS-232 and IR control extension for remote device management, and remotely powers compatible receivers over HDBaseT using IEEE 802.3af PoE to simplify endpoint installation. Balanced analog audio de-embedding with volume control provides a direct feed to an external audio system from any HDMI source. HDCP 2.2 compliance, EDID management, HDBaseT link testing, and TCP/IP or RS-232 control compatibility with Atlona Velocity and third-party control systems round out the AT-HDR-CAT-2 feature set.

Frequently Asked Questions

Q: What is the maximum 4K HDR distribution distance for the AT-HDR-CAT-2?The AT-HDR-CAT-2 distributes 4K HDR signals up to 130 feet (40 meters) per output over CAT6a or CAT7 cable. Using CAT5e or CAT6 cable, the maximum 4K HDR distance is 115 feet (35 meters). For 1080p signals, distances extend to 230 feet (70 meters) on CAT6a/7 or 200 feet (60 meters) on CAT5e/6.Q: Can a local monitor be connected alongside the two HDBaseT distribution outputs?Yes. The AT-HDR-CAT-2 includes a dedicated HDMI pass-through output for connecting a local display directly at the source location, in addition to the two HDBaseT outputs that feed remote displays.Q: Which receiver is recommended for use with the AT-HDR-CAT-2?Atlona recommends the AT-HDR-EX-70C-RX for 4K/60 4:4:4 HDR applications. The AT-UHD-EX receivers are also compatible for 4K/60 4:2:0 applications.Q: Does the AT-HDR-CAT-2 support display automation without a control system?Yes. The built-in CEC display control feature sends power on/off commands to displays connected via the HDMI pass-through and HDBaseT receiver outputs using the front-panel POWER button, IP commands, or RS-232, without requiring a separate control processor.Q: How is audio de-embedded and what output is available?The AT-HDR-CAT-2 de-embeds stereo 2-channel audio from the HDMI input to a balanced analog output via 5-pin captive screw connector, with volume control capability. Multi-channel audio formats including Dolby Atmos and DTS:X pass through to the HDBaseT and HDMI outputs.Q: Can the AT-HDR-CAT-2 power remote receivers without a separate power supply?Yes. Each HDBaseT output supplies IEEE 802.3af Power over Ethernet to compatible receivers, eliminating the need for local AC power at remote display locations. Maximum power consumption with both PoE outputs active is 38.3 W.Q: Is the AT-HDR-CAT-2 compatible with Atlona Velocity and third-party control systems?Yes. The unit supports TCP/IP, RS-232, and IR control interfaces, providing full compatibility with Atlona Velocity as well as third-party control systems such as Crestron, AMX, and Extron.
