Behringer Feedback Destroyer FBQ1000 EQ Question

New

I just bought and installed a Behringer Feedback Destroyer FBQ1000 in my home Rehearsal Studio.


We had Feedback issues becaus eit's a small room; I set it for AUTO to control Feedback and it truly works!


BUT NOW; I notice; sometimes after playing 15 minutes; it seemes to mess the with EQ; and all of a sudden there is MINIMAL BASS and LOW END on our mix?


I am not super Techno Savvyl but I know in my setting; under Filter; it syas "AUTO"


Is there a way I can "Turn Off" the Parametric EQ Filter (from AUTO) and still have this device eliminate Feedback?


Let me know any suggestions and thnaks!
