Atlona 4K HDR Transmitter and Receiver Set w/IR, RS-232, Ethernet and PoE - AT-HDR-EX-100CEA-KIT

Product Overview

The Atlona AT-HDR-EX-100CEA-KIT is a matched transmitter and receiver set for extending 4K HDR HDMI signals over a single category cable run up to 330 feet (100 meters), designed for boardrooms, auditoriums, house of worship installations, and commercial AV systems requiring true HDR and full 4K/60 4:4:4 signal delivery. Unlike standard HDBaseT extenders, this kit employs visually lossless compression technology to transmit high data rate HDR and 4K/60 4:4:4 content—which exceeds 10 Gbps—over a single CAT6/6a/7 cable while maintaining pristine image quality with no latency. The AT-HDR-EX-100CEA-KIT 4K HDR HDBaseT extender kit supports HDR10, Hybrid-Log Gamma (HLG), and Dolby Vision, with HDCP 2.2 compliance and HDMI data rates up to 18 Gbps. IR, RS-232, Ethernet, return audio via optical, and PoE are all included in both the transmitter and receiver units.

Product Description

The AT-HDR-EX-100CEA-KIT consists of the AT-HDR-EX-100CEA-TX transmitter and the AT-HDR-EX-100CEA-RX receiver, providing a complete point-to-point HDMI extension solution for advanced 4K HDR deployments. The visually lossless compression engine applies extremely light compression with zero perceptible latency, enabling the transmission of HDR10, Dolby Vision (in Low Latency Dolby Vision mode at 60 Hz), and HLG at 4K/60 over a single structured cabling run—a challenge that uncompressed HDBaseT systems cannot address at this resolution and color depth. The transmitter accepts a single HDMI input and outputs via HDBaseT to the receiver, which outputs to HDMI at the destination display. Both units include an RJ45 LAN port for Ethernet pass-through, an RS-232/IR captive screw connector for control signal extension, and an optical TOSLINK port for return audio. The transmitter features a TEST button and blue TEST LED for quick link verification in the field. The receiver is powered by the external 48 V power supply included in the kit; the transmitter receives power over HDBaseT (PoE) from the receiver, so no local outlet is needed at the source end. HDCP 2.2 ensures compatibility with the latest protected content sources and displays. The kit supports a comprehensive range of video resolutions including 4096x2160 and 3840x2160 DCI/UHD formats at up to 60 Hz, 1080p, 720p, and VESA resolutions, plus UltraWide 21:9 resolutions up to 3840x1600. Color depth up to 12-bit is supported. Audio pass-through covers PCM 2.0/5.1/7.1, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, Dolby Atmos, DTS Digital Surround, DTS-HD Master Audio, and DTS:X with sample rates up to 192 kHz and bit depth up to 24 bits. The AT-HDR-EX-100CEA-KIT carries CE and FCC certification, and the power supply adds cULus, RoHS, CCC, and RCM certifications. NDAA Section 889 compliance is confirmed. Both units have a compact low-profile enclosure (1.02 x 5.74 inches footprint) suitable for surface mounting, table installation, or placement in an equipment rack with an optional rack shelf.

Key Features

• 4K HDR Extension with Visually Lossless Compression — Transmits HDR10, Dolby Vision (LLDV @ 60 Hz), and HLG at 4K/60 over a single category cable by applying extremely light, zero-latency compression to overcome HDBaseT bandwidth limits.
• HDMI Data Rates up to 18 Gbps — Supports 4K/UHD @ 60 Hz with 4:4:4 chroma sampling and up to 12-bit color depth, accommodating the full range of current 4K HDR source devices.
• HDBaseT Transmission up to 330 ft (100 m) — Extends HDMI over a single CAT6/6a/7 cable at full 4K/UHD resolution; CAT5e achieves 295 ft (90 m) at 4K/UHD.
• HDCP 2.2 Compliant — Supports the latest High-bandwidth Digital Content Protection specification for protected source and display device chains.
• RS-232 and IR Pass-Through — Extends RS-232 (up to 115200 baud) and IR (30–60 kHz) control signals from the transmitter location to the receiver location for integrated display and device control.
• Ethernet Pass-Through — Both transmitter and receiver include an RJ45 LAN port for network connectivity pass-through alongside the video signal.
• Return Audio via Optical (TOSLINK) — Both units include an optical audio port, supporting audio routing in both directions for integrated sound systems.
• PoE Powering for Transmitter — The receiver supplies power to the transmitter over the HDBaseT cable, eliminating the need for a local power outlet at the transmitter/source location.
• Comprehensive Audio Pass-Through — Passes PCM, Dolby Atmos, DTS:X, DTS-HD Master Audio, Dolby TrueHD, and other multi-channel formats with sample rates up to 192 kHz and 24-bit depth.
• Field Link Testing — Transmitter includes a TEST button and blue LED indicator for quick verification of the HDBaseT cable run; software analyzer tool available for detailed reporting.
• NDAA Section 889 Compliant — Confirmed compliance for use in U.S. government installations subject to National Defense Authorization Act supply chain requirements.
• Compact Low-Profile Enclosures — Both TX and RX units measure 1.02 x 5.74 inches (H x W) for flexible surface or rack installation.

Frequently Asked Questions

Q: Does the AT-HDR-EX-100CEA-KIT support Dolby Vision at 4K/60 Hz?

Yes, with a condition. 4K Dolby Vision at 60 Hz is supported only on systems capable of Low Latency Dolby Vision (LLDV) mode. All other Dolby Vision modes are limited to 4K/30 Hz over this extender kit.

Q: What makes this kit different from a standard HDBaseT extender?

HDR and 4K/60 4:4:4 content requires HDMI data rates exceeding 10 Gbps, which standard uncompressed HDBaseT cannot carry. The AT-HDR-EX-100CEA-KIT uses visually lossless compression with no perceptible latency to overcome this limit, enabling true HDR and 4K/60 4:4:4 transmission over a single category cable up to 330 feet.

Q: What cable type is required for 4K HDR at 330 feet?

CAT6, CAT6a, or CAT7 cable is required to achieve the full 330 ft (100 m) distance at 4K/UHD. CAT5e cable supports 4K/UHD up to 295 ft (90 m) and 1080p up to 330 ft (100 m).

Q: Does the transmitter require its own power supply?

No. The transmitter is powered over the HDBaseT cable via PoE from the receiver unit. Only the receiver requires an AC connection using the included 48 V power supply.

Q: Is the AT-HDR-EX-100CEA-KIT NDAA compliant for government installations?

Yes. The kit is confirmed compliant with NDAA Section 889 requirements, making it suitable for U.S. federal and government facility installations.

Q: What control signals can be passed through this kit?

RS-232 (up to 115200 baud) and IR (30–60 kHz) pass-through are supported, enabling display and device control commands to be sent from one end of the extension to the other. Ethernet is also passed through via RJ45 ports on both units.

Q: What audio formats does the kit support?

The kit passes PCM 2.0, LPCM 5.1/7.1, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, Dolby Atmos, DTS Digital Surround, DTS-HD Master Audio, and DTS:X, with audio sample rates up to 192 kHz and up to 24-bit depth. Both units also include a TOSLINK optical port for return audio routing.
