8x8 Matrix for HDMI (Black) Gefen GTB-HDFST-848-BLK


Route any eight HDMI Inputs to any eight HDMI Outputs with Gefen FST and support for 3DTV

The GefenToolBox 8x8 Matrix for HDMI routes eight Hi-Def sources to any eight HDTV displays. Resolutions up to 1080p Full HD and 1920x1200 plus 3DTV are supported, along with multichannel digital audio formats such as Dolby® True HD and DTS-HD Master Audio™.

The 8x8 Matrix eliminates the need to disconnect and reconnect Hi-Def sources. It works with any Hi-Def source that needs to be connected to any display using HDMI. Each source can be routed to any display using the front-panel push buttons, IR remote control, RS-232 interface, or over IP using the built-in Web interface.

How It Works

Connect the Hi-Def audio/video sources to the eight HDMI inputs using the supplied HDMI cables. Connect up to eight displays to the HDMI outputs. 3D content can be displayed from the 3D source when a 3D-capable display is connected to Output 1. Connect the external power supply to the matrix and plug the power cable into an available electrical outlet. Apply power to all of the sources and displays.

Gefen FST

Fast Switching Technology (FST) is a Gefen software implementation for 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.
