Atlona 4K/UHD 8x2 Multi-Format Matrix Switcher with Dual HDBaseT/Mirrored HDMI - AT-UHD-CLSO-824

Product Overview

The Atlona AT-UHD-CLSO-824 is a 4K/UHD 8x2 multi-format matrix switcher designed for dual-display commercial AV environments including classrooms, conference rooms, and divisible meeting spaces. It accepts eight inputs—four HDMI, three HDBaseT, and one analog—and routes them to two independent HDBaseT outputs, each with a mirrored HDMI port, enabling flexible signal distribution to local and remote displays over a single category cable up to 328 feet. The unit’s built-in audio mix-matrix allows integrators to blend de-embedded digital audio with mic/line inputs and route the result to balanced analog outputs or re-embed it to the video outputs, eliminating the need for a separate audio processor in many installations. With Ethernet-enabled HDBaseT ports, Power over Ethernet for connected transmitters, and support for 4K/UHD @ 60 Hz, the AT-UHD-CLSO-824 serves as a complete AV distribution core for two-zone presentation systems.

Product Description

The AT-UHD-CLSO-824 is purpose-built for dual-zone commercial AV installations where independent content must be delivered to two separate displays from a shared pool of eight source inputs. Its multi-format input architecture supports four HDMI sources for rack-mounted equipment, three Ethernet-enabled HDBaseT inputs for remote presenters at lecterns or conference tables, and one multi-function analog video input for legacy sources. Each HDBaseT output provides 4K/UHD signal extension up to 100 meters over CAT6a/7 cable, with a mirrored HDMI port on each output for connecting a local display or feeding an Atlona extender kit. Power over Ethernet is available on all HDBaseT inputs and outputs, which simplifies cabling by eliminating dedicated power supplies for compatible transmitter endpoints. The Atlona HDVS-200 series transmitters are compatible with the HDBaseT inputs for placement at remote source locations. The integrated audio mix-matrix is a significant operational advantage in corporate and education environments: it de-embeds digital audio from the selected video source and allows it to be mixed with signals from two mic/line inputs before routing the combined output to balanced analog line outputs or re-embedding it into the HDBaseT/HDMI output streams. This capability makes the AT-UHD-CLSO-824 suitable for teleconference systems where content must simultaneously reach a display and a codec. The unit also extends IP control signals over HDBaseT to connected displays, reducing control system complexity in rooms where centralized AV management is required. At 1 RU, it installs in a standard equipment rack and is certified CE and FCC.

Key Features

• 8x2 Multi-Format Matrix Switching — Routes any of eight inputs to two independent outputs, with each output carrying both an HDBaseT and a mirrored HDMI signal for flexible display connectivity.
• 4K/UHD Support @ 60 Hz — Supports 4096x2160 and 3840x2160 resolutions at up to 60 Hz (4:2:0 at 60 Hz; 4:4:4 at 30 Hz and below), compatible with current 4K source and display equipment.
• Three Ethernet-Enabled HDBaseT Inputs — Accepts remote source connections from lecterns, conference tables, or instructor stations over a single category cable carrying AV, control, Ethernet, and power.
• Dual HDBaseT Outputs with Mirrored HDMI — Each of the two outputs provides an HDBaseT connection for remote display extension up to 328 ft (100 m) and a local HDMI port for a display at the rack.
• Power over Ethernet on All HDBaseT Ports — Remotely powers compatible Atlona HDBaseT transmitter and receiver endpoints, reducing installation complexity and cabling requirements.
• Audio Mix-Matrix — De-embeds digital audio from selected video sources and mixes it with two mic/line inputs; the combined signal routes to balanced analog outputs or is re-embedded into digital outputs.
• Balanced Analog Audio Outputs — Provides professional-grade balanced line-level audio outputs for integration with installed sound systems or recording equipment.
• IP Control Extension over HDBaseT — Passes Ethernet control signals from third-party control processors to connected displays over the HDBaseT output cable, simplifying control system wiring.
• Multi-Format Input Support — Accepts HDMI, HDBaseT, and analog video inputs in a single chassis, accommodating a wide range of source equipment without additional signal converters.
• 1 RU Rack-Mount Form Factor — Fits into a standard 19-inch equipment rack, suitable for permanent installation in AV equipment rooms and closets.

Frequently Asked Questions

Q: Does the AT-UHD-CLSO-824 support true 4K @ 60 Hz on the HDBaseT outputs?

The unit supports 4K/UHD at 60 Hz over HDBaseT at 4:2:0 chroma subsampling using CAT6a/7 cabling up to 100 meters. Full 4:4:4 chroma subsampling is supported at 4K resolutions up to 30 Hz. For 1080p signals, the full 100-meter extension distance is available regardless of cable type.

Q: What HDBaseT transmitters are compatible with the three HDBaseT inputs?

The AT-UHD-CLSO-824 is compatible with Atlona HDVS-200 series transmitters including the AT-HDVS-200-TX and AT-HDVS-200-TX-WP for wall plate installations. These transmitters accept HDMI and VGA inputs and are powered via PoE from the switcher, requiring only a single category cable for AV, control, and power.

Q: Can the two outputs show different content at the same time?

Yes. The 8x2 matrix architecture allows each of the two outputs to be independently routed to any of the eight inputs simultaneously. This supports divisible room configurations, dual-display boardrooms, and installations where a confidence monitor must show different content from the main display.

Q: How does the audio mix-matrix function in a conference room installation?

The audio mix-matrix de-embeds audio from the selected video source and allows it to be combined with signals from two mic/line inputs. The resulting mix is sent to balanced analog line outputs for the room’s audio system and simultaneously re-embedded into the HDBaseT/HDMI output streams, providing a complete integrated audio solution without a separate audio DSP.

Q: Does the switcher extend IP control signals to connected displays?

Yes. The Ethernet-enabled HDBaseT outputs pass IP control signals to connected display devices or control processors at the far end, allowing a centralized control system to communicate with displays without additional control wiring runs to each screen.

Q: Is the AT-UHD-CLSO-824 compatible with non-Atlona HDBaseT receivers?

The AT-UHD-CLSO-824 uses the HDBaseT standard for its inputs and outputs. While Atlona’s own extender products are tested and recommended, it may be compatible with other HDBaseT-certified devices. Contact Creation Networks at creationnetworks.net for compatibility guidance specific to your installation.

Q: What is the warranty on this product?

The AT-UHD-CLSO-824 is covered by Atlona’s standard product warranty. Complete terms are available at atlona.com/warranty. For purchasing information, contact Creation Networks at creationnetworks.net.
