The Gefen ToolBox GTB-HD4K2K-442 4x2 Matrix for HDMI 4Kx2K is a compact and lightweight alternative to rack-mounted matrixes. It allows up to four Ultra High Definition 4K x 2K or Full HD 1080p sources to be routed to up to two Ultra HD displays. The GTB-HD4K2K-442 supports resolutions up to 4K x 2K (3840 x 2160@30Hz). HDCP, Deep Color, 3DTV pass-through, and lossless audio formats such as LPCM 7.1, Dolby¨ TrueHD, and DTS-HD Master Audio are also supported. Each Hi-Def source can be routed to either of the connected displays using the front panel push-button controls, the included IR remote, RS-232 serial control interface, or through IP, using Telnet, UDP, and the built-in web server interface. LED indicators on the top panel display the current routing status, FST mode, audio configuration, and EDID settings.

User Application

The Gefen GTB-HD4K2K-442 is ideal for home theater systems, multiroom installations, retail establishments, sports bars, schools, museums, hospitals, hotel lobbies, and any other installations where Ultra High Definition HDCP-compliant AV content from up to 4 HDMI sources needs to be routed to up to two Ultra HD displays.

How It Works

Connect up to four Ultra Hi-Def sources to the HDMI inputs on the GTB-HD4K2K-442 matrix using HDMI cables. Connect up to two Ultra HD displays to the HDMI outputs. Connect an Ethernet cable from the network to the RJ-45 connector to use the built-in web server or Telnet/UDP capability to control routing, EDID management, and other functions. Connect an RS-232 cable between an automation control device such as Gefen EXT-PACS and GTB-MINI-PACS and the matrix. Connect the included locking power supply to the matrix and to an available electrical outlet. Apply power to the sources and displays. The HD sources can now be routed to the displays using the front panel push-buttons, IR remote control, RS-232, Telnet, UDP, or web server interface.
