I've got a couple Rode NT2000 mics. They work great in ORTF configuration
(11 o'clock pattern setting), but when I try the mid-side configuration I
can't get a stable stereo image, and there are holes in the pattern at
different frequencies.
I tried the cardioid mid with the mic standing vertically, and the
figure-eight side with that mic placed directly behind the mid in a
horizontal orientation. Very poor image that actually jumped back and forth=
in the phones as I whistled and moved from 0 to 90 degrees. I guess it's
path-length cancellation effects.
Should the side mic be directly above the mid mike, and if so, how does one=
do that with a stereo bar and the spider mounts that come with studio mics?=
Anyone do MS with studio mics in the field?
I also tried a near-coincident Blumfield (two figure 8's @ 90 degrees and a=
head-width apart) but the center image was weak and phasey.
