I have a crown xli 1500 coming ina few days. 
A couple questions-- 
1- how do i set gains, it has clip indicators but surely i dont go off that alone.
Secondly, im using xlr to rca cords ans i noticed just below the rca inputs there's a selector switch saying 1.4v or .775v , what should i be using?
