The GefenPRO GEF-HDFST-848-4ELR is a 8x8 HDMI Matrix Router. The HDMI router has four ELR and four HDMI outputs which routes up to eight Hi-Def sources at resolutions up to 1080p Full HD with Deep Color and multi-channel digital audio to any of eight HDTV displays, eliminating the need to disconnect and reconnect HDMI sources and displays. It features extension of four displays up to 330 feet (100 meters), using Gefen's ELR (Extra Long Range) and POL (Power Over Link) technologies. ELR extension on four outputs allows installation of displays over a single CAT-5e cable. POL eliminates the need to externally power the four included ELR receivers. The GefenPRO 8x8 Matrix supports 3DTV and advanced digital audio formats such as Dolby® TrueHD and DTS-HD Master Audio™. Each source is accessible at all times from any display by using the included IR Remote Control, the RS-232 port, IP (Telnet or Web GUI).

How It Works:

Using HDMI cables, connect up to eight Hi-Def sources to the HDMI inputs on the matrix. Connect up to four HDTV displays to the HDMI outputs on the matrix and up to four HDTV displays to the supplied ELR-POL receivers. Use a single CAT5e cable to connect each of the receivers to the matrix. An external power supply is not required because power is delivered by the matrix over the CAT5e cables. 3D content can be displayed when connecting a 3DTV and 3D source. Turn on the matrix by pressing the power switch. The Hi-Def sources can now be routed to any display by using the IR remote control, RS-232 port, IP (Telnet or Web GUI), or by using the front-panel push buttons.

What is Gefen FST Fast Switching Technology (FST)? FST is a software implemented by Gefenfor HDMI products. FST was created to improve the lengthy HDMI authentication process, based on the HDMI and HDCP specifications. FST allows for connecting/disconnecting or turning any of the HDTV displays on or off without affecting other displays within the audio/video distribution system.


  • Shielded (STP) CAT5e or CAT6a is recommended. Unshielded (UTP)CAT5e or CAT6a may be acceptable depending on cable quality but is not the top choice.
  • POL (Power Over Line) technology from Gefen uses the Ethernet channel to send power to the Receiver unit.
