Hi all-newbie here with a question. My daughter's HS marching band also performs orchestral music (upper college and sometimes professional level pieces) at a local church sanctuary which is huge-seats about 3000. Next month the chorus will be doing the show along with the band. So I'm looking for advice on mic placement,how many mics I would need,and which mics would work best. For a reference just read my equipment list on my profile page. Thanks to all for the help.
