IIRC (and this does need checking!!) -the output from the mic is not inverted, BUT, -if you use the old mini-XLR to normal-XLR converters that also convert 48V phantom to 5V phantom, then these do invert. Sorry can't remember where I read that ... but it was a long time ago. Len (as in CoreSound) now offers a box (small cigarette packet) rather than the old 'tubes' (XLR diameter). As these allow switching between internal 1,5V internal battery and external 48V on the normal-XLR lead, I am not sure if they consistently invert or not. If no-one knows, I'm happy to do some expt's for you. (We have both a tube and a box.)
