Hi @boing, the first issue I immediately notice is that you are pushing your audio signal really hard and way into the Red because you have all your EQs boosted past 12 o’clock. In general, you don’t want to always be boosting your EQs past the 12 o’clock position. You should really avoid pushing the audio signal into the red as this will cause distortion in the audio signal. Please note, that when the crossfader is in the center position, both of your decks are playing at maximum volume, so with your EQs and Channel Faders set as high as they are and already in the red, distortion of the master audio is expected. Please refer to this helpful article about properly setting volume levels when DJing: How To Set Your Volume Levels Like a Pro When DJing - Digital DJ Tips
In the djay Settings>Sound you should consider turning On the Audio Limiter to prevent clipping and distortion of the audio signal. You should also consider adjusting the Output Headroom. I hope that helps!
