Almost all condensor mics require phantom power, which this box doesn't have. It **is** a preamp, but doesn't have a lot of features. You can get outboard phantom power boxes (in fact, a friend of mine gave me a four-channel one) but, if you haven't already put out the bucks for it, you might look for something in the same price range that include the power. The Edirol UA-25 is $240US, and includes 2 channels of phantom power, MIDI ports, a headphone jack, and connects via USB.
