I work at a church Ans we’ve been have pops and drop outs for months . A whole lot of equipment replacement after a lightning strike has gotten us to the point that we think we have everything new. But today testing with new…. Xlr cables , amplified speakers and subs , x32 2 years old , s32 newer than a year , mic’s , spearing out antenna ls for other equipment…. We don’t know what to do. Made sure board and s32 was synchronized. Clean power, not on same grid as air conditioning system. We are lost . Help Please any ideas?
