Some big shit is going down for me, I'm hosting an MC battles thing, but bottom line -- I need to get a couple Wireless mics. I want 2 Wireless (ShureSM58) mics, I'm looking @ STV58D "The Vocal Artist" package ($260) which gives you the mic N' receiver... basically everything you need... BUT... the location is generally close to an Air-Port [maybe a mile?, I'm not sure exactly], I think "The Vocal Aritst" transmits on RF. Is RF good enough? Or do I need to go and get a UHF mic? If I do need to go and get a UHF (shure SM58) mic then how much can I get one for? I see one thats $600 in which case I can only get one of them. I would rather get 2mics with the money I have, then buy 1 and make the MC's go back and fourth... What do you think? P.S -- "The Vocal Artist" systems have 1 channel.. Will this mean interferance? Or will each channels be different from each other? PLEASE HELP ME! I WILL TRY TO REPAY YOU.
