It’s unlikely IEMs would be the cause of your feedback, although if you have poor gain structure you could be getting digital clipping somewhere in the signal chain, which would sound bad.

If it is actual feedback though my money would be on mic/speaker placement (specifically their pickup/coverage patterns,) and their associated eq, room resonances, using too much make-up gain on various compressors so when those compressors engage you exceed your gbf limit (especially if a lot of them engage all at once,) or you’ve accidentally created a feedback loop somewhere, eg sent an fx return back to its send, or you’ve tried to get creative with psuedo subgroups and have accidentally double bussed something etc.
