ok, so its time for my schools talent show, and we just bought two sm94s, that are friggin awsome, any way we have an accepella group preforming, and there hard to hear in the back of the house, so on top of a solo mic i was thinking of putting the sm94s, or two sm58s on the outter front corners of the group, our auditorium does have oh mics but there crap, they only work for listening to my crews conversations when im in the boost (heh heh heh also gave me blackmail capablities) any way whats a better option for micing them
