    Disembedded audio from BM SDI-to-HDMI converter extremely loud?

    Is anyone familiar with the Blackmagic Mini Converter SDI-to-HDMI and using disembedded analog audio from it? I am currently in an editing suite where the signal path is...

     

    MacPro (2013) -> BM UltraStudio Express ->

    via SDI (embedded audio) -> BM SDI-to-HDMI converter ->

    via HDMI (embedded audio) to TV ->

    via unbalanced audio out from TV -> Mixer

     

    Instead of the unbalanced audio (from TV to mixer) I would like to utilize the balanced audio outputs of the SDI-to-HDMI converter. So I connected the converter to the mixer, using TRS-jack <-> XLR cables. The audio now finds its way to the mixer but with an apparently very high volume. Mixer faders are just a little bit above nothing and the signal already starts clipping. Input gain on the mixer is set to minimum and my avid mix is far from being too loud. Am I overseeing an option to reduce the volume of the SDI-embedded audio before it arrives at the mixer?

    What mixer are you using? I recall having used Mackie mixers that would have balanced TRS inputs for line inputs, but XLR inputs for MIC inputs. If you are feeding a balanced line signal into an input of a Mic preamp, it would pretty soon starts to overload.

    Things to check.

     

    1. Mixer for TRIM/GAIN input level. Or a button for line level.

    2. The cable is correct and not damage

    3. Not sure about the converter, but see if there is a jumper or software setting to change audio line levels.

    HI-LA-RI-OUS! It is not a Mackie but something pretty much alike. I was one zillion percent sure that those inputs were NO mic connectors and therefore did not bother to check again. ;) So thank you, Sherlock ter Burg! And, of course, thank you for your suggestions, too, Dom Q. Silverio.
