I have a behringer 5 channel(probably the model just below yours). It doesent have phantom power to run my condenser mic, so now I'm just using a one channel presonus tube preamp.
I just recorded a whole song using this 1 mic and preamp(vocals,drums, bass, and guitar. It sounds better than when I was using 3 mics on my drums thru the behringer mixer.
They make a 2 channel version for 199, I might get that and another condenser mic and just leave it at that.
