Quick Overview

One 3G-SDI input becomes four.



Manufacturer Part Number: EXT-3GSDI-144

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

How It Works
You simply connect your SDI source to the 1:4 3G SDI Splitter input, then connect its outputs to your SDI Devices. Once the source, the SDI devices and the Splitter are powered and connected, your source's video will be distributed 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.
