Better to rewire the XLR off the mike itself.outrecording said:And for polarity. The mic is reversing polarity for whatever reason. Doing it in the DAW is fine, but takes ages when you have 4 tracks of hundreds of minutes at 24bit 96k. And I've forgotten to do this several times. So I'd just assume take care of it at the source.
You pay a huge price in making the Input Loop larger with a polarity switch. Why not put it on the output of the preamp? Easier switching and much less critical.
I think your Chinese fireworks are likely the loudest stuff you'd record with an Ambisonic mike.
