Congratulations on your purchase of the 4x1 3G-SDI Switcher. Your complete
satisfaction is very important to us.
Gefen
Gefen delivers innovative, progressive computer and electronics add-on solutions
that harness integration, extension, distribution and conversion technologies.

The Gefen 4x1 3G-SDI Switcher
The Gefen 4x1 3G-SDI Switcher allows any one of four high-bandwidth 3G-SDI,
HD-SDI or SDI sources to be switched to a single output without a switching
delay or loss of signal quality. Ideal for cutting equipment costs in the studio by
enabling shared signal routing, this 3G-SDI Switcher supports source resolutions
up to 1080p and has convenient switching methods.
How It Works
Up to four 3G-SDI sources connect to BNC input jacks on one side of the Gefen
4x1 3G-SDI Switcher. A single 3G-SDI output connects on the output side. Power
is applied to the 4x1 3G-SDI Switcher and a vibrant video picture is transmitted
to the output device. Any 3G-SDI input source is selectable via the included
IR remote control or a selector button on the front panel of the 4x1 3G-SDI
Switcher. Selection of sources may also be performed by using the RS-232
communications port.
