When I measure my speakers using REW and UMIK-1, the Step Response looks like the signal is with inverted polarity. From the plug-in I haven't inverted any channel and I checked all amp-speaker connections, they are all correct. So why is this happening? Do the OpenDRC inverts phase internally or is it UMIK-1?

No, the OpenDRC-DA8 unit does not invert polarity (unless you program it to.)
A positive-going signal encoded in your digital input will yield a positive-going signal at the analog outputs.

You have a polarity reversal somewhere else in your testing scheme.

I repeated the measurement with a skype microphone and now REW shows a positive polarity. So it seems that UMIK-1 has incorrect polarity. Or am I missing something?

Can somebody confirm if the UMIK-1 has inverted polarity?

I've noticed phase reversal on my system as well but never had any problem with that. I'm using UMIK1 as well.
