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

Overview

The Atlona AT-UHD-CLSO-824 is an 8-input, 2-output matrix switcher designed to deliver 4K/UHD video, audio, and control signals simultaneously to two displays via mirrored HDBaseT and HDMI outputs. It supports 4K resolution at 60 Hz, making it suitable for presentation environments like classrooms, meeting rooms, and training labs that require flexible signal routing and reliable long-distance transmission.

This switcher accommodates a variety of sources with three HDBaseT inputs for remote devices up to 328 feet away, four local HDMI inputs for nearby equipment, and a multi-format analog input for legacy devices. Its mirrored outputs allow identical content to be sent to a ceiling projector and a confidence monitor, simplifying multi-display setups.

Key features

• Eight inputs feeding two mirrored outputs enable simultaneous display on projector and monitor
• Supports 4K and Ultra HD signals at 60 Hz for detailed and smooth video playback
• Three HDBaseT inputs extend signals up to 328 feet over a single category cable, reducing cable clutter and installation complexity
• Four HDMI inputs provide easy connection for local digital sources such as media players and video conferencing devices
• Multi-format analog input ensures compatibility with older computers and document cameras
• Integrated audio matrix mixer blends program audio with two mic or line inputs, delivering balanced audio output for external amplification or processing
• Switchable audio de-embedding allows audio to be routed separately from video, supporting rooms with existing sound systems
• Power over Ethernet (PoE) powers compatible transmitters and receivers directly from the switcher, minimizing the need for additional power supplies
• Control options include TCP/IP, RS-232, and infrared, enabling seamless integration with third-party control systems
• Built-in EDID and HDCP management tools simplify setup and ensure protected content plays without interruption

Connectivity and compatibility

The switcher’s combination of HDBaseT and HDMI inputs covers a wide range of modern and legacy devices, making it easy to integrate laptops, media players, video conferencing codecs, and older analog sources into a single system. The HDBaseT outputs carry video, audio, Ethernet, power, and control signals over a single cable, simplifying installation and reducing cable runs to displays located far from the source equipment.

• HDBaseT inputs and outputs support long-distance transmission with a single category cable
• HDMI inputs accommodate high-definition digital sources with plug-and-play convenience
• Analog input supports legacy devices without requiring additional converters
• Control options allow integration with common AV control platforms for centralized management

Performance and reliability

Designed for professional AV environments, this matrix switcher ensures stable and consistent signal delivery with built-in HDCP and EDID management. The internal audio matrix mixer provides flexible audio routing and mixing, allowing presenters to combine microphone audio with program content seamlessly. Power over Ethernet support reduces the need for extra power adapters, enhancing reliability and simplifying installation behind walls or ceilings.

Ideal uses and environments

This matrix switcher fits well in educational settings, corporate meeting rooms, and small lecture halls where multiple sources need to be routed to dual displays. It is especially useful in spaces requiring long cable runs to remote sources or displays, such as podiums, overflow rooms, or ceiling-mounted projectors. The integrated audio features and control options make it a strong choice for AV integrators seeking a streamlined, all-in-one solution for flexible presentation setups.
