HDMI to SDI cable converter

By Dave

The Blackmagic micro converters are easy to use as no setup is required. Picture quality is great. The only complaint is we had two of them fail in the last year, one was covered in warranty and the other was out of warranty.

Wow!

I needed to run an HDMI signal from the church sanctuary to the fellowship hall through an existing coaxial cable. I accomplished this by converting the HDMI to SDI. I needed an SADI to HDMI converter on the receiving end. I got the converter quickly and in time for the evening Christmas service. B&H is my hero.
