TP4, MBA M3, and S4 M3. Deck D seems to have one channel louder than the other. I can't figure out why? Deck A and B are set to external, and C and D are track decks. If I load a track into C, the channels are fairly balanced. If I load a track into D, the channels favour the left one. This is displayed both on Traktor and the S4 MK3.
Thought it might be an effect or the Ozone Maximiser, but switched both off, and the same output. Not sure what is going on…
