Atlona 4K/HDR HDMI 2.0b HDBaseT HDMI 1X4 Exten Distance Distribution Amplifier - AT-HDR-CAT-4ED

Product Overview

The Atlona AT-HDR-CAT-4ED is a commercial-grade 4K HDR HDBaseT extended distance distribution amplifier designed to distribute a single HDMI 2.0b source to four displays over Category 6/6A cable at distances up to 330 feet (100 meters). Purpose-built for large-scale AV installations where long cable runs are required, this 4K HDBaseT distribution amplifier supports HDR10, HLG, and Dolby Vision formats with full 4:4:4 chroma sampling at 60 Hz. Integrators deploying multi-display HDMI signal distribution in hospitality, commercial, or education environments will find the AT-HDR-CAT-4ED a reliable single-rack-unit solution. With HDCP 2.2 compliance, visually lossless compression, and support for cascading up to eight units, it scales cleanly across complex HDBaseT video distribution systems.

Product Description

The AT-HDR-CAT-4ED addresses a common challenge in commercial AV deployments: distributing 4K HDR content to multiple displays across distances that exceed the practical limits of standard HDMI cabling. With four independent HDBaseT outputs, each capable of transmitting 4K/UHD at 60 Hz with 4:4:4 chroma sampling to distances of 330 feet over Cat 6/6A, this unit eliminates the need for intermediate repeaters or signal boosters in most installations. The inclusion of a local HDMI pass-through output allows a monitor to be connected directly at the rack, making it straightforward to verify signal integrity during commissioning without additional test equipment.

For AV systems integrators working in hospitality environments such as hotel lobbies, restaurant bar areas, or retail digital signage deployments, the extended distance capability is a primary differentiator over standard-reach distribution amplifiers. Each HDBaseT output carries not only video and audio but also Ethernet, bidirectional RS-232, IR control, and Power over HDBaseT to compatible receivers, consolidating multi-signal delivery into a single Cat cable run per display. This substantially reduces conduit fill and labor costs on larger installations.

The AT-HDR-CAT-4ED supports audio de-embedding to a balanced analog output with volume control, enabling integration with commercial audio systems without requiring a separate audio extractor. EDID management allows integrators to store and lock display EDID profiles, preventing source devices from changing output resolution when displays are powered off. CEC control enables display power commands to be issued over HDBaseT from the control system or front panel, reducing the need for separate IR blasters at each display location. The built-in HDBaseT link test function provides a direct pass/fail verification of cable plant quality during installation, streamlining commissioning and reducing callbacks. Compatible receivers include the AT-HDR-EX100CEA-RX for full 4K/60 4:4:4 HDR performance and AT-UHD-EX series receivers for 4K/60 4:2:0 applications.

Key Features

• Extended Distance HDBaseT Outputs — Four HDBaseT outputs transmit 4K HDR signals up to 330 ft (100 m) over Cat 6/6A, eliminating intermediate repeaters in most commercial installations.
• Full 4K/60 4:4:4 HDR Support — Carries HDR10, HLG, and Dolby Vision content at full 4:4:4 chroma sampling and 60 Hz frame rate using visually lossless compression over HDBaseT.
• HDCP 2.2 Compliance — Supports the latest content protection specification, ensuring compatibility with protected 4K UHD sources including streaming devices and Blu-ray players.
• Local HDMI Pass-Through Output — Provides a direct HDMI output at the rack for local monitoring or connection of an additional HDMI display without consuming an HDBaseT port.
• Audio De-Embedding — Extracts PCM stereo audio to a balanced +4 dBu analog output with volume control for routing to a separate commercial audio system.
• Bidirectional RS-232 and IR Per Output — Each HDBaseT output extends RS-232 and IR control signals bidirectionally, enabling full control system integration at each display location.
• Power over HDBaseT — Remotely powers compatible Atlona HDBaseT receivers over the Cat cable, eliminating the need for local AC outlets at display endpoints.
• EDID Management — Stores and manages EDID profiles from connected displays or internal presets, ensuring consistent source output resolution regardless of display power state.
• HDBaseT Link Testing — Integrated link test verifies cable plant quality, termination integrity, and link margin at each output during installation and troubleshooting.
• Cascade Support — Up to eight units can be cascaded to expand distribution capacity without signal degradation, supporting large-scale multi-display deployments.
• Web-Based Configuration GUI — Integrated web server provides browser-based access to EDID, HDCP, network, and control settings from any device on the network.
• 1U Half-Rack Width Enclosure — Compact form factor installs in standard 19-inch racks with included mounting hardware; two units can be mounted side-by-side in a single rack unit.

Frequently Asked Questions

Q: What cable type is required to achieve the full 330-foot 4K HDR transmission distance?

Category 6A or Category 7 cable is required to reach the maximum 330-foot (100-meter) transmission distance at 4K/UHD resolution with HDR. Category 5e or 6 cable will support 4K/UHD up to 230 feet (70 m) and 1080p up to 330 feet (100 m). Shielded cable is recommended in environments with significant electrical interference.

Q: Which Atlona receivers are compatible with the AT-HDR-CAT-4ED for full 4K/60 4:4:4 HDR performance?

The AT-HDR-EX100CEA-RX is the recommended receiver for full 4K/60 4:4:4 HDR performance at the extended 330-foot distance. AT-UHD-EX series receivers are also compatible but are limited to 4K/60 4:2:0 chroma subsampling. Confirm receiver specifications before finalizing your system design.

Q: Does the AT-HDR-CAT-4ED support HDCP 2.2 protected content from 4K streaming devices and Blu-ray players?

Yes. The AT-HDR-CAT-4ED is fully compliant with HDCP 2.2, which is required for protected 4K UHD content from sources such as streaming media players, 4K Blu-ray players, and cable/satellite set-top boxes. The entire signal chain from source to compatible receiver must be HDCP 2.2 compliant for protected content to pass.

Q: Can the AT-HDR-CAT-4ED be integrated with third-party control systems such as Crestron, Extron, or AMX?

Yes. The unit supports TCP/IP (Telnet), RS-232, and IR control interfaces, making it compatible with virtually any commercial control system including Crestron, Extron, AMX, QSC, and others. It is also compatible with Atlona Velocity with integrated AMS for centralized management and monitoring.

Q: Does the unit provide Power over HDBaseT to connected receivers, and is a local power outlet required at the display?

Yes, the AT-HDR-CAT-4ED provides Power over HDBaseT to compatible Atlona receivers, eliminating the need for a local AC outlet at each display location. This is a significant installation cost reduction in multi-display deployments where running AC to each display position is impractical or expensive.

Q: How does the audio de-embedding output work, and what connector is used?

The unit de-embeds PCM stereo audio from the HDMI source and outputs it as a balanced analog +4 dBu signal via a 5-pin captive screw connector. This output includes a software-controllable volume level and is suitable for direct connection to commercial audio systems, mixers, or amplifiers without requiring an external audio extractor.
