So then, if I were to buy that microphone, I would plug it into a microphone preamp, then run a cord from the preamp to the FDP? Can you point me to an online source to buy the cords? And, would all the connectors on these two cords be balanced 1/4" TRS connectors?

Another question: By using this FDP, would you be "doing" what is considered room EQ?

EDIT: I emailed Behringer a question, and they suggested what I would want is another product of theirs:
ULTRACURVE PRO DEQ2496
