BobL Tech: PA goes berserk (42) RE: Tech: PA goes berserk 08 Dec 19

"Tucked in a closet" - so presumably it was the house PA system?
"Loud, raucous, scratchy blast of sound" - but you're not a heavy metal band...

If the problem suddenly cropped up without anyone touching anything, then it could indeed be a fault somewhere - anywhere - in the PA system. Main amp, one of the channels, something plugged into it. You don't say if the mics were wired or wireless: wireless mics can pick up interference. Did anyone try to track down the problem afterwards? Like by disconnecting everything and turning all volume controls to zero before powering up the system again? That's how I'd have started looking into it.
