Hi all. Just bought the DL1608 and loving it. I'm using an Airport Express with Djay 2 over Airplay. I've run the audio from the Airport Express into Ch 1 (panned left) and Ch 2 (panned right) Only thing is I loose most of the bass and kick drum etc. I can solve this by boosting the lower frequencies in the DL eq, but strangely, I have turn one of the polarity buttons on or the the bass just disappears again. If I turn both polarity switches on, the bass disappears again. Just one on does the trick and it doesn't seem to matter which one. I would really like to understand this and am asking if someone can guide me as to the correct set up for Airplay music from the Airport Express. TIA.
