Rich and Lang,
I sure do relate to "low end - good quality", Rich! I tried your conversion
trick, to turn a ME 64 cardioid into a ME 62 omni. Sennheiser will be very
pleased to know that it didn't work!! What a disappointment!
As I understand it, an omni mic should sound as loud and clear from both
front and sides, (if for example, you were speaking into it.) Is that how
your ME 62 responds Rich? I tried many combinations of blocking various
vents on the ME 64, but I always had a cardioid effect, i.e. loud and clear
at the front, but much less at the side.
I will look at Sennheiser's website for more clues.
Lang's suggestion of "near-coindicent" sounds good. I guess that's why I'm
a bit unhappy with the crossed pair, they are not spacious enough.
Compatability with mono shouldn't be a big issue; if I want to study
sonograms or whatever, I can just choose one track in Peak and make a mono
file.
