strange profiling results - SOLVED

Hi,
I tried some profiling today.
Signal chain:
Gtr -> KPA input -> KPA send -> clean amp -> 2mics into my audio Interface -> summing the two signals in Cubase -> mono out into KPA return -> KPA analog out to audio interface

pretty standard....

here is the resulting profile:

audio example

Have you ever experienced something like this?
All my levels were carefully set, no clipping involved.
Got the same results over and over again, even after restarting the KPA

I did another test with the simplest setup possible, GTR -> KPA in -> KPA send -> amp -> mic -> KPA return

everything went fine

there must be a mistake with the setup going through my DAW.

problem solved!

it was a routing mistake in my RME Fireface mixer

thanks for chiming in
