HDMI to 3GSDI Scaler (Discontinued)




HDMI Converted to 3G-SDI with Scaling, Multichannel Audio and Genlock

This product has been discontinued and replaced by the GefenPRO GEF-HDVI-2-3GSDIS.

The GefenPRO HDMI to 3GSDI Scaler converts from HDMI source to single link or dual link SDI formats on the output. Resolutions scaled up to 1080p, 1920x1200, and 2K with genlock and up to 8 channels of audio is supported. The built-in S/PDIF audio output can be used to send digital audio to a separate A/V receiver. This product uses the VXP scaler which provides high-performance scaling plus additional features: Adaptive video interlacing with edge interpolation, advanced noise reduction, alpha blending, image enhancement, and a fully-integrated menu system. This product supports SDI, HD-SDI, and 3G-SDI SMPTE 425-A and 425-B formats. The GefenPRO HDMI to 3GSDI Scaler provides superior 3G-SDI video packaged in a single rack mount unit with an internal power supply.

How It Works


Connect a Hi-Def source to the GefenPRO HDMI to 3GSDI Scaler with the supplied HDMI cable. Connect the 3G-SDI device to the BNC video connectors on the output. Use another coax cable to connect an external clock to the Reference-In BNC connector. Connect a digital audio cable between the S/PDIF connector on the product and the A/V receiver. Apply power to the source and 3G-SDI device and apply power to the product. The Hi-Def source will be converted to 3G-SDI. Use the IR remote control unit to navigate the built-in menu system to control the scaling features on the 3G-SDI output.
