Just to quickly chime in.
Don't confuse 'phantom power' (or +48v) with the concept of a 'powered' or 'unpowered' mixer. They are totally different things. Phantom power is used to charge condenser (capacitor) microphones and should be available on every mic channel of a desk that you're going to use. If not, it's a real headache.
