4×4 4K/UHD HDMI to HDMI Matrix Switcher

4x4 4K/UHD HDMI to HDMI Matrix Switcher

The Atlona AT-UHD-H2H-44M is an HDMI matrix switcher with advanced control capability. It routes any 4K/UHD @ 60Hz (4:2:0, 8-bit) source to any 4K/UHD destination with full HDCP 2.2 content protection. For ease of setup and management, the matrix includes a GUI-based integrated web server for HDCP/EDID reporting, system configuration, and device status. The WebGUI uses an easy, intuitive drop down menu for fast setup and troubleshooting in the field. Additional control capabilities include I/O routing from tablets, smart phones or PCs. The matrix is control system-friendly and integrates with any TCP/IP, RS-232, or IR-based control system. Flexible control capability is also provided by the supplied IR remote and front panel controls. The AT-UHD-H2H-44M is ideal for professional HDMI signal routing in residential and commercial applications were a number of AV sources must be shared throughout four zones to reduce the installed equipment footprint and to reduce the costs associated with multiple, redundant devices. The AT-UHD-H2H-44M features a 1U, rack-mountable enclosure with an external, international power supply.

HDMI Distribution with HDCP 2.2 Content Protection

As ultra-high definition sources and displays become more readily available, the need for 4K/UHD signal distribution with the latest High-bandwidth Digital Copy Protection (HDCP) standards becomes critical. The AT-UHD-H2H-44M was designed to ensure system designers, integrators and owners are not caught off-guard as these content protections are enforced at the source. Even if the matrix is installed to upgrade an existing matrix or to expand a system using older content protection standards, system owners can be assured that the matrix at the heart of their system will not need to be replaced as the source and display equipment gets updated the newer standards that come with 4K/UHD content.

The AT-UHD-H2H-44M is ideal for professional installation in:

  • Multi-zone applications to distribute multiple HDMI signals
  • Applications where HDCP 2.2 standards will be enforced by 4K/UHD sources
  • Long distance HDMI distribution with Atlona UHD-EX Series Extenders

Configured and Managed by AMS

The AT-UHD-H2H-44M also supports the Atlona Management System (AMS), a powerful network software platform that integrates product configuration, management and updating. Specially designed for IP-controllable Atlona Products, the Atlona Management System reduces installation time and enables remote monitoring and support. To learn more please visit AT-SW-AMS.
