The LINDY HDMI to SDI Converter/ Extender allows a HDMI video signal to be converted for display on SDI displays. Supporting resolutions up to 1080p & with a built-in 3.5mm audio input means that you can insert sound from a different audio source instead of the HDMI audio on the SDI output. This is an ideal product for sending a HDMI video signal to a SDI display as well as converting HDMI signals to 3G-SDI. Use in conjunction with our SDI to HDMI Convertor to create a DVI-D Extender capable of distances up to 100m using low cost coaxial cable.
