The Atlona AT-UHD-PRO3-88M is a high-performance, enterprise-grade matrix switcher designed for complex 4K/UHD audio-visual distribution in commercial and institutional environments. This 8x8 matrix supports eight HDMI inputs and provides eight independent outputs that utilize HDBaseT technology for long-distance transmission over a single CatX cable. Its core function is to allow any input source—such as media players, computers, or video conferencing systems—to be routed to any combination of displays, projectors, or video walls simultaneously, with full support for ultra-high-definition video, multi-channel audio, and control signals. This flexibility makes it ideal for boardrooms, command and control centers, museums, and digital signage networks.

The switcher distinguishes itself with dual-distance HDBaseT output capability, offering two distinct transmission modes to optimize performance based on cable length. For distances up to 100 meters (330 feet), it uses standard HDBaseT transmission, while for shorter runs, a high-bandwidth mode supports the full 18 Gbps data rate required for 4K at 60 Hz with 4:4:4 chroma sampling. Each output also provides Power over HDBaseT (PoH), delivering both power and signal to compatible HDBaseT receivers, which simplifies installation by eliminating the need for separate power supplies at the display end. The matrix includes advanced video processing features such as scaling and frame rate conversion on each output, ensuring optimal compatibility with connected displays of varying resolutions and capabilities.

Designed for reliability and ease of management, the AT-UHD-PRO3-88M features a robust metal chassis with redundant, hot-swappable power supplies for mission-critical applications. Control and configuration are achieved through a web-based GUI, front-panel interface, RS-232, or IP automation systems. It supports comprehensive EDID and HDCP 2.2 management to handle content protection and source negotiation smoothly. By integrating high-density switching, long-distance extension, power delivery, and video processing into a single unit, this Atlona matrix provides a scalable and future-proof backbone for demanding professional AV systems.
