As long as the Output LED gets red, the Volume is too high. But you can compensate through the Master volume, or raising the active cabs' one (or rising the Kemper's poweramp's one) in order to keep the same SPL.
It's natural that clean sounds clip much more than distorted sounds, and if the output LED goes heavily red you're basically making the D\A converter tilt!
I'm having this issue too - DI profile of my amp head was too low for the profiler to "hear it" so I had to turn off the Gain reduction switch on the DI,
Now when ever I play - the LED in output is always red or orange.
How do I fix this for this profile - there's no Cab section, just Amp and EQ.
I get the same "clipping" issue as discussed in this thread, Looking for a fix.
