We have used Mackie, Behringer, and Nady mixers with various power-needing microphones. As I remember it, the mics specify 1.5, 5, 12 and 48 volts, or Phantom Power mixers. I find this voltage variation mysterious (hence the name "Phantom"?). Our use has been for field and studio recording situations, rather than a lab. We sometimes buy mixers from Musician's Friend <www.musiciansfriend.com>.
