Behringer C2 Stereoset
These were purchased primarily for amplifying a mixed choir of about 15 men and women, in an environment which did not really allow for fixed microphones. I set these up on a stand using the supplied bar which allows you to mount a stereo pair on the one stand.
Initially I set this up with both mics pointed directly at the choir. Results were pretty good, with a light, airy quality to the reproduction through the sound desk. However, these really came into their own when I used them as an XY pair, each mic pointing at the opposite corner of where the performers were... this gave a much fuller sound.
These mics have been used regularly over the last 3 years with no issues, despite the stand having to be regularly moved around. I would definitely recommend them.
