INTRODUCTION
Congratulations on your purchase of the 2:8 HDTV Distribution Amplifier. The 2:8 HDTV
distribution amplifier is an innovative solution for anyone with more complex computer
system requirements, like studios and presentation venues where multi-viewing is essen-
tial. The 2:8 HDTV distribution amplifier accommodates various system scenarios. Most
commonly, two video sources (either DVI-equipped computer, DVD player or satellite set
top box) are connected to the distribution amplifier on one side. On the output side, eight
video outputs are available to be used in part or in full. Once the unit is connected and
powered, each source can be routed to multiple displays. All DVI displays are driven by
the two DVI sources with each source or computer capable of driving eight displays at one
time. For home theater applications, the unit is HDCP (high definition content protection)
compliant, making it effective for use with all HDTV displays.
How it works:
Gefen’s ex•tend•it 2:8 HDTV distribution amplifier is an expandable distribution hub that
sends the same DVI graphics source to eight DVI based digital screens (flat panels or
projectors). It is a flexible solution that accommodates multiple DVI displays. You can
switchfromsourceone andtwo viathe RMT-2IR remotecontrol.The 2:8HDTV distribution
amplifierisalso equippedwith anauto sensing featureto switchbetween whateversource
is active. When one source is inactive it will automatically switch to the active source.
The ex•tend•it 2:8 HDTV distribution amplifier is connected with a DVI (male to male)
cable from the DVI graphic source to the distribution amplifier input. There are eight DVI
outputs in each module. DVI output one is the primary connection and is used for the main
display. DVI output 2 thru 8 follow the main display. The 2:8 HDTV distribution amplifiers
is using a unique DVI Bus™ technology to connect multiple amplifiers without sacrificing
a DVI output connection. The ninth output is an expansion output used to daisy chain an
additional 2:8 HDTV DistributionAmplifier. The 2:8 HDTV DistributionAmplifier is expand-
able to 256 outputs (32 HDTV DA’s).
