Atlona 5x1 4K HDR HDMI Matrix Switcher - AT-HDR-SW-51

Product Overview

The Atlona AT-HDR-SW-51 is a 5x1 HDMI switcher with full support for high dynamic range (HDR) formats, delivering 4K/UHD video at 60 Hz with 4:4:4 chroma sampling and data rates up to 18 Gbps. Part of Atlona’s comprehensive 4K HDR integration product family, this five-input HDMI switcher with HDR accepts five HDMI sources and outputs to a single HDMI display, making it a practical solution for conference rooms, meeting spaces, and commercial AV installations that require HDR-capable source switching. The AT-HDR-SW-51 includes selectable 4K-to-1080p downscaling, automatic input selection, audio de-embedding to balanced analog and S/PDIF outputs, and HDCP 2.2 management, and is controllable via Ethernet, RS-232, and IR.

Product Description

The Atlona AT-HDR-SW-51 is a 5x1 HDMI switcher designed for high dynamic range formats including HDR10, Hybrid Log-Gamma (HLG), and Dolby Vision at 60 Hz. It supports 4K/UHD video at 60 Hz with 4:4:4 chroma sampling and HDMI data rates up to 18 Gbps, making it compatible with current and emerging 4K HDR sources and displays. HDCP 2.2 compliance enables protected content to pass through the system, while HDCP management can be disengaged to allow non-protected material to reach non-compliant displays, streaming devices, and teleconference systems. Selectable 4K downscaling converts 4K/UHD video at 60, 30, or 24 Hz to 1080p output for use with HD displays, video conferencing codecs, and legacy sink devices. Automatic input selection uses HPD signal detection and active video monitoring to switch to a newly connected source without user intervention. Audio de-embedding extracts two-channel PCM audio from any selected HDMI input to both S/PDIF and balanced analog (L/R RCA) outputs, and extracts 5.1 channel bitstream audio to the S/PDIF output, enabling direct integration with external audio systems. Multi-channel audio formats including Dolby Atmos, DTS:X, and DTS-HD Master Audio pass through the HDMI output to a compatible display or audio processor. EDID management ensures the correct video resolution and audio format is negotiated with the source. Control is via Ethernet (HTTP), RS-232, and IR, with integration support for Atlona Velocity and third-party control systems. The AT-HDR-SW-51 installs in a 1U, half-rack-width enclosure with included surface mounting hardware for under-table installation and rack mount ears for full-rack-width equipment rack installation.

Technical Specifications

Frequently Asked Questions

Q: What HDR formats does the AT-HDR-SW-51 support?

The AT-HDR-SW-51 supports HDR10, Hybrid Log-Gamma (HLG), and Dolby Vision at 60 Hz. It is designed for current and emerging 4K HDR sources and displays.

Q: Can the AT-HDR-SW-51 downscale 4K content for a 1080p display?

Yes. The unit includes selectable 4K-to-1080p downscaling that converts 4K/UHD at 60, 30, or 24 Hz to 1080p output. Downscaling can be bypassed to allow full 4K/60 4:4:4 and 4K HDR pass-through when connected to a 4K-capable display.

Q: How does audio de-embedding work on the AT-HDR-SW-51?

The switcher de-embeds two-channel PCM audio from the selected HDMI input to both the balanced analog L/R outputs (RCA) and the S/PDIF output. It also de-embeds 5.1 channel bitstream audio exclusively to the S/PDIF output. This allows direct connection to an external amplifier, DSP, or audio processor without an additional audio interface.

Q: Does the AT-HDR-SW-51 support automatic input switching?

Yes. The unit uses HPD signal detection and active video monitoring to automatically switch to a newly connected HDMI source. This enables simplified presenter operation in conference rooms where laptops are frequently connected and disconnected.

Q: What is the maximum HDMI cable length for 4K sources?

The AT-HDR-SW-51 supports HDMI cable runs up to 15 feet (5 meters) for 4K/UHD sources, and up to 30 feet (10 meters) for 1080p sources.

Q: Is the AT-HDR-SW-51 TAA compliant?

Yes. The AT-HDR-SW-51 is both TAA compliant and NDAA Section 889 compliant, making it suitable for government, federal agency, and publicly funded education procurement.

Q: How is the AT-HDR-SW-51 controlled in a managed AV system?

The unit is controllable via Ethernet (HTTP/Telnet), RS-232, and IR. It integrates with Atlona Velocity control systems and is manageable through Velocity Device Manager for centralized configuration and firmware updates. Third-party control systems with RS-232 or TCP/IP support can also interface with the unit using the published API.

Q: What is the difference between the AT-HDR-SW-51 and the AT-HDR-SW-52?

The AT-HDR-SW-51 has a single HDMI output (5x1 configuration). The AT-HDR-SW-52 is a 5x2 matrix switcher with two independent HDMI outputs, and the AT-HDR-SW-52ED additionally includes an HDBaseT output for long-distance extension.
