I have noticed for many years that the audio signals of the PA4x are not equal
is this normal? or is there something wrong with the keyboard? maybe my mixer?


check out the image here that I recorded the keyboard

Have you done the usual troubleshooting stuff?

Different cables
Different outputs (use the headphone outs set under half volume to not introduce any distortion)
Different mixer channels
Check your DAW interfaces settings, check gain and pan settings
Run a different keyboard or a CD player or phone output through the same signal path (is that uneven too?)

The answer will probably become apparent after checking those…
