'Endfire' (that is with the mic's 'top' pointed towards the soundstage, rather than the classic mic in a vertical position: with 'endfire' the 'handle' and the cabling point horizontally away from the soundstage).
A word of caution though: If my memory is correct then TetraMic phantom power converters (or some of them) invert, before the signal reaches any software (see previous post). > Am I saying the same thing as you (but with different words)? Maybe I > should have said a "list"? Mmm a database seems 'a sledgehammer to crack a nut' ... but equally too many projects are not designed to allow for growth. In this case, though, a webpage might be the best start, as there do seem so many potential 'footnotes'/caveats that make the data set rather unclean.
