Notching out feedback:
I’m having a problem with a high frequency feed back at gigs. I’m using a L1 model II with a T8S (love it!). I have the instructions for using the Para EQ to attempt to notch out the frequency but I obviously can’t do this at a gig with people present. I’ve tried cutting back Highs on each mike channel as well as on reverb but this hasn’t solved the problem. I’ve also tilted the mikes up (we have 3 EV 967 mikes).
My question is this: is there a frequency range that is usually the culprit for very high pitched feed back that I could cut out ahead of time that might help elevate this?
