Different audio level on 2 channels

Hey guys,
it's been a long time since i used Cross and i decided to try it again because of several updates. I connected everything how i should (i think so). I use 2 CDJ 800 and a DJM 700 and the u46 inteface. But now when i play a track the audio level on input 1/2 is higher than on 3/4. There is no problem with the cdjs, i switched channels on both of them but there is always a higher audio level on 1/2 than on 3/4. I used the same track on both decks to test this. I use timecode.
Hopefully someone can help me
