The Gefen GEF-3GSDI-2-HDS is a 3G-SDI to HDMI Scaler which converts a single, or dual, link SDI source to HDMI while providing high performance scaling on the output. Resolutions up to 1080p and 2K with eight channels of audio are supported. The built-in S/PDIF audio output is used to send multichannel digital audio to a separate A/V receiver. This unit provides cadence detection, frame rate conversion, advanced noise reduction, detail enhancement and a fully integrated menu system. SDI, HD-SDI, and 3G-SDI SMPTE 425-A and 425-B input formats are all supported. The GefenPRO 3GSDI to HDMI Scaler provides superior 3G-SDI to HDMI conversion and scaling packaged in a single rack mount unit with a built-in internal power supply.

How to use: Connect your 3G-SDI input source to the GefenPRO Scaler and the output using an HDMI cable to your HDTV display. Connect a digital audio cable between the S/PDIF connector on this unit and the A/V Receiver. The 3G-SDI source will be converted to HDMI. Use the IR remote to control the scaling features on the HDMI output.
