The Gefen 2:8 HDMI Distribution Amplifi er is the perfect solution for anyone who
needs to send one or two sources of digital high defi nition video to multiple displays
at the same time. It supports HDMI equipment, such as DVD players, satellite set
top boxes, and HDMI displays. In operation, the digital source is connected to the
distribution amplifi er’s input while eight HDMI outputs are available to be used
in part or in full. Once the unit is connected and powered, your source can be
distributed up to eight digital displays at the same time.

How It Works

Simply connect your HDMI video source to the 2:8 Distribution Amplifi er’s input
using the supplied HDMI cable. Then connect up to eight HDMI displays to the unit’s
eight HDMI outputs. Once connected and powered, your source will be seen on all
eight displays at the same time. When two or more 2:8’s are connected together,
you can create a larger distribution system.
