Can someone please give me some tips on Corrective EQ?
Basically, my OKM Rock Microphone tends to show a not quite linear progression - regardless of the location and the PA. And in the range 4500-8500 Hz it also falls off a bit (please see screenshot). When I try to "straighten" the EQ course in iZotope RX, the recording sounds noticeably better. I've put together a few screenshots of "iZotope RX", as a basis for discussion.

If I increase certain frequency ranges in my recording in such a way that a linear progression occurs, clipping inevitably occurs. On the other hand, if I say to the program that it bluntly takes over the EQ of a professional "similar" recording, the new course of my original recording is nearly similar, but no clipping occurs.
However, I just would like to get the basic characteristics of my original recording and just correct the frequency response a bit.
So what would be the correct course of action, starting from my RAW recording?
Option 1:
Raise the frequency areas with lower ranges. As a result, clipping occurs.
Option 2:
Reduce the overall level first, to get enough headroom so that no clipping can occur. Then raise the frequency areas with lower ranges. Then raise the overall level to maximum.
Option 3:
Lower the frequency with higher ranges, to obtain a linear frequency response. Then raise the overall level to maximum.
To reduce the total power of the very deep frequencies, I could live with an additional applied high pass filter, but I definitely want to preserve the deep bass.
Please excuse my bad English and thanks in advance! ;-)
