Congratulations on your purchase of the ex•tend•it 4x2 HD-SDI Switcher. Your complete
satisfaction is very important to us.
Readily Access One of Four Sources with One or Two Displays
4 Sources + 1 or 2 Displays = Cost Effective Multi-Tasking
The ex•tend•it 4x2 HD-SDI Switcher is unique in its ability to connect two HD-SDI
displays to four HD-SDI sources. Select from multiple sources using the IR remote
control that comes with the unit. When selected, a source may be viewed on either one
or two HD-SDI displays. Source switching is completed swiftly and high definition video
up to 1080p is supported.
SDI
SDI (serial digital interface), used primarily in broadcasting, converts and transmits digi-
tal video through SDI connectors. It enables computers to process high definition, high
quality video.
How it Works
Connect your HD-SDI sources and the one or two HD-SDI displays to the 4x2 HD-SDI
Switcher. When all the equipment is powered and connected, switching can begin.
The ex•tend•it line offers solutions for noise, space and security concerns, data center
control, information distribution, conference room presentation, school and corporate
training environments.
Our Commitment
Gefen will always offer the finest quality product at the best possible price. Included in
that price is a lifetime of support from a team of outstanding engineers.
The ex•tend•it 4x2 HD-SDI Switcher allows two HDTV DVI devices to be switched easily
in to one HDTV DVI compatible monitor or projector. The 4x2 HD-SDI Switcher can also
be placed at the end of a long DVI cable to regenerate the DVI signal.
