QuoteDisplay More- Main out Kemper (XLR) straight in the X32 inputs (Stereo)
- X32 BUS (stereo) in to my In-Ear and from there wireless to my receiver en UE 11Pro
When I use the Cab instead of the IEM I use the Jacks mail out in to my Custom Transistor Amp and from there in my Cab. All stereo as well.
Assume you mean "main", not "mail" there 
This explains your problem. You are sending the same signal to the PA as the one you are sending to your amp and 4x12 guitar-cab. That means that the effect your amp and cab has on the sound do not apply to the PA.
The better way to do this is to :
- use monitor-out into your amp+cab, and main-out to into the PA.
- Set cab emulation off for the monitor-outputs in output settings. Also set monitor to stereo and connect direct-out to your amp for a stereo
- Disconnect main-outs from the master volume in output-settings to enable adjustment of monitor volume independent from what you send to the PA. At the same time you can also enable the 10dBm output reduction for the main outputs. That will stop most audio-techs from complaining that your KPA's outputs are too loud.
- Re-adjust the rigs you use on the KPA so that they again sound good through the 4x12. (Now without cab-emulation in the KPA)
- If the emulated cab in each rig now has characteristics similar to your physical cab, then you should achieve a very similar sound through the PA (which still has cab-emulation active).
With rigs in the KPA that use an emulated cab very different from your physical cab then you may struggle to make the PA sound the same. One amp into two different cabs can be almost like two different amps. The cab colors the sound a lot. This is why most people seem to prefer to use a neutral monitoring solution and keep cab-emulation on for both monitor and main outputs.
