With four HDMI inputs and one HDMI output, the Gefen GTB-HD4K2K-441 switcher allows you to route four Ultra HD sources to one Ultra HD display, so you can easily manage your game console, Blu-ray player, set-top box. or other A/V equipment in your home entertainment system. It features HDCP, Deep Color, 3DTV pass-through, and lossless audio formats such as Dolby TrueHD and DTS-HD Master Audio, and is future-proof with the support for Ultra HD 4K x 2K. Gefen's FST technology speeds up the HDCP authentication process.

LED indicators on the top panel display the current switching status. Available in Black or White

How It Works

Connect up to four Ultra Hi-Def sources to the HDMI inputs on the switcher using HDMI cables. Connect an Ultra HD display to the HDMI output. 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 switching. Connect an RS-232 cable between an automation control device, such as the Gefen EXT-PACS or GTB-MINI-PACS, and the switcher. Connect the included locking power supply to the switcher and to an available electrical outlet. Apply power to the sources and display. The HD sources can now be routed to the display using the front panel push-button, IR remote control, RS-232, Telnet, UDP, or web server interface.
