Dsp main eq issue

I have noticed recently a issue with main dsp eq issue
On the low bass frequency and low mid frequency,if you push it up it only applies more to the left channel if you go down minus it applies more to the right channel
And then the styles sounds unbalanced
When i owned the audya 5 didn’t have this problem but the audya 4 does,anyone with this issue
When i keep it flat on dsp and eq on the mixer it sounds amazing

What Ketron synth do you have?

I myself have noticed a problem with the SD1000 DSP
The DSP1 and DSP2 does not have the same level, so if I apply one at left, and one at right, then the 2 ears doesn't have the same level
Maybe the same problem?

I have audya 4
