I just got a used DL1608, but after a week with troubleshooting I still haven´t figure out whats wrong. I have downloaded the latest app "My master 3.1" and it did an upgrade to the firmware on the DL. I got signals to the DL (led lamp is blinking), I am "connected" in my app, but no signals in the meters. Same happens to severeal iPads and versions, and I´m also connected when I´m using wifi to connect, but no signals showing up in the iPad. And of course no sound out in the Main or phones. Any suggestion what to do? I have tried the reset button back at the mixer, but it seems to only put the mixer into an upgrade mode? And after I upgrade firmware, same result. Got connected, but no signals from the mixer to the iPad. Anyone have any suggestions?
