This Version of the HD-SDI Splitter has been discontinuted. See the new Gefen HD-SDI Distribution Amplifer / Splitter.
The Gefen 1:4 HD-SDI Distribution Amplifier is the most reliable, cost-efficient, and simple way to split your one SDI (or HD-SDI) source to mirror simultaneously on 4 displays.
SDI
Short for Serial Digital Interface, it is used primarily in broadcasting and professional Audio/Video. It enables video sources to process high definition, high quality video.
Connect your SDI source to the 1:4 SDI Splitter's input, and up to four SDI displays or devices to the outputs. The source, displays, and splitter must be powered. Once powered, the highly defined crisp SDI visuals appear simultaneously on all for displays. Multiple formats (NTSC, PAL), and resolutions (720 to 1080p) are fully supported.
