Left / Right Level difference

  • Hey guys,


    Sorry for my english, I'm french ;)


    So, everything is in the title, I got a Left / Right Level difference.
    I have tested my cables and changed my interface (apollo twin, Komplete audio 6 and other mixers...).
    RIG panorama is also dead center.


    Any idea?
    Probably an hardware issue but I wanted to know if anyone had experienced it too?


    Thanks
