Splitters >> SDI Splitters >> 1:4 3GSDI Splitter




One 3G-SDI Input Becomes Four

The 1:4 3G-SDI Distribution Amplifier allows a single SDI, HD-SDI or 3G-SDI video source to be distributed to as many as four Hi-Def SDI/HD-SDI/3G-SDI devices at the same time without loss of signal. Crisp, highly defined visuals are generated in NTSC or PAL formats supporting Standard and High Definition resolutions up to 1080p Full HD at 60 Hz.


How It Works


Connect an SDI source to the 1:4 3G-SDI Splitter input, then connect its outputs to SDI Devices. Once the source, SDI output devices and the Splitter are powered and connected, the source video will be distributed to all 3G-SDI monitors or output devices simultaneously in pristine color and detail.

Note:  Gefen's 1:4 3G-SDI Splitter is backwards compatible with all Gefen legacy SDI equipment and signal types.
