Atlona AT-HDR-EX-70C-TX 4K HDR Transmitter with IR, RS-232, Ethernet & PoE (230')

Product Overview

The Atlona AT-HDR-EX-70C-TX is a 4K HDR HDBaseT transmitter that extends 4K/UHD video at 60 Hz with full 4:4:4 chroma sampling, plus HDR10, HLG, and Dolby Vision, up to 130 feet (40 meters) over CAT6/6a cable. This 4K HDR HDBaseT transmitter for commercial AV installations uses visually lossless compression to deliver full-color 4K HDR content over standard category cabling at distances that standard HDMI cables cannot achieve. AV integrators requiring an HDBaseT transmitter with HDR10 and Dolby Vision support will find the AT-HDR-EX-70C-TX suited to conference rooms, classrooms, and digital signage applications. The unit also extends 1080p signals up to 230 feet (70 meters), passes RS-232 and IR control signals, and supplies remote power to compatible receivers over the HDBaseT link.

Product Description

The Atlona AT-HDR-EX-70C-TX (SKU: AT-HDR-EX-70C-TX) is a HDBaseT transmitter for 4K and high dynamic range (HDR) content. It supports extension of 4K/UHD video at 60 Hz with 4:4:4 chroma sampling plus HDR metadata, multi-channel audio, control signals, and power up to 130 feet (40 meters) over Category 6/6A cable, or 1080p up to 230 feet (70 meters). Unlike the UHD-EX Series, the HDR-EX Series employs visually lossless compression with no perceptible latency, enabling full 4:4:4 color fidelity and HDR formats including HDR10, Hybrid Log Gamma (HLG), and Dolby Vision at 60 Hz over standard HDBaseT.

The AT-HDR-EX-70C-TX is the primary transmitter for point-to-point 4K HDR extension when paired with the AT-HDR-EX-70C-RX receiver. It can also be used as a remote HDMI input point for the AT-UHD-CLSO-824 matrix switcher and AT-UHD-SW-5000ED presentation switcher, transmitting 4K/UHD at 60 Hz 4:2:0 from a remote source location to the switcher's HDBaseT input.

HDCP 2.2 compliance ensures the unit can handle the latest copy-protected content from streaming devices, Blu-ray players, and commercial media players. The AT-HDR-EX-70C-TX passes bidirectional RS-232 (up to 115,200 baud) and IR (30 kHz to 60 kHz) control signals over the HDBaseT link, and provides remote power to compatible receivers such as the AT-HDR-EX-70C-RX over the same cable, reducing installation complexity.

A front panel TEST button and multi-colored TEST LED enable HDBaseT link quality verification in the field, including cable continuity, termination quality, and link integrity — a significant time-saver during commissioning. The compact enclosure (1.02 x 4.29 x 5 inches) supports mounting in furniture, a lectern, or an equipment rack. Rear panel connections keep cables organized and simplify wire management. Firmware is field-updatable via the front panel Micro-A USB port. The unit draws only 6.07 W and is NDAA-899 and TAA compliant, making it suitable for government and education procurements.

Frequently Asked Questions

Q: What is the difference between the AT-HDR-EX-70C-TX and the AT-UHD-EX-70C-TX?

The AT-HDR-EX-70C-TX is part of the HDR-EX Series and supports full 4K/60 4:4:4 chroma sampling, HDR10, HLG, and Dolby Vision, plus auto EDID correction and hot plug detection management. The AT-UHD-EX-70C-TX is from the UHD-EX Series and supports 4K/60 4:2:0 chroma sampling with HDR10 limited to 24 Hz. Choose the HDR-EX-70C-TX when full-color 4K HDR fidelity is required.

The AT-HDR-EX-70C-TX extends 4K HDR signals up to 130 feet (40 meters) over CAT6/6a/7 cable, or 115 feet (35 meters) over CAT5e. For 1080p, the range extends to 230 feet (70 meters) over CAT6/6a/7.

Q: Does the AT-HDR-EX-70C-TX support Dolby Vision?

Yes. The AT-HDR-EX-70C-TX supports Dolby Vision at 60 Hz on systems capable of Low Latency Dolby Vision (LLDV) mode. For systems not supporting LLDV, 4K Dolby Vision is limited to 30 Hz.

Q: What receiver is required to use the AT-HDR-EX-70C-TX?

For point-to-point 4K HDR extension, the AT-HDR-EX-70C-TX is designed for use with the AT-HDR-EX-70C-RX receiver. It is also compatible with the AT-UHD-CLSO-824 and AT-UHD-SW-5000ED switchers for 4K/UHD 4:2:0 input extension.

Q: Can the AT-HDR-EX-70C-TX power the receiver without a separate power supply at the display?

Q: How does the HDBaseT link test function work?

Pressing the TEST button on the front panel initiates a cable and link quality test. The multi-colored TEST LED reports the result: a green indication signals a healthy link, while other colors indicate degraded or failed conditions. This feature aids in fault isolation during commissioning and troubleshooting.

Q: Is the AT-HDR-EX-70C-TX suitable for government procurement?

Yes. The AT-HDR-EX-70C-TX is both NDAA-899 and TAA compliant, meeting federal and state government procurement requirements for AV equipment.
