Audio signal for sound card calibration (rme ucx2)

[Alessiom]

Good morning, I'm trying to calibrate my RME UCX2 sound card but as you can see in the screenshot, the red is higher than the signal. in the various tutorials I see that it is practically attached to the clean peak, why not here? Thank you

The levels I put before were related to the check level while when I do the calibration the levels are what I inserted now. The problem is that if I increase the input or output gain this clips and everything stops because it exceeds 0. How can I solve it?
I can't go beyond this level, beyond that it clips and reaches 0.

Thanks again

I tried this way which is the only one that allows me to do it, is this correct?

The problem is that if I increase the input or output gain this clips and everything stops because it exceeds 0.

Generally due to monitoring the input and so feeding it back to the output. The usual cure is to mute the input in the interface mixer panel.
