use mic with Behringer DEQ2496

I am a very beginner but had a chance to own a pro device since it was second-hand and cheap :)
all I need is to connect my microphone into the DEQ, use the limiter, equalizer while I am making the voice-over, then get the corrected voice into my audio interface (Zoom H6)
Is it possible at all?
I tried some of the obvious solutions but none of them being successful.
I can connect my mic into the left or right inputs and connect the left or right output into my Zoom H6. in this situation I get a clear voice into my zoom when I bypass my DEQ!!! any attempt to get a signal without bypassing, was failing
what am I missing?
Thank you in advance and very sorry for my basic question
