What are you trying to do? A700's for main stage, distributed sound with 4612's? Two separate sound systems?
Multiple mikes? Condenser or dynamic? (makes a difference with the mixer settings).
I'd suggest it worth the investment to hire a sound person that's wiling to work with you to sort your
needs vs. equipment out, perhaps run it one year as a mentor to a responsible person at your church,
and then write up a procedure for you.
There's no reason for things to sound awful if the equipment is working correctly and set up properly.
