I came across an old DL1608 for €200 and snapped it up as a spare as I have one of the very first ones to come out that has served me well but is going to flake out one of these days and I just sold my last analogue standby mixer. Everything works fine despite signs of heavy usage except Aux 3. The signal is present on the ipad and in the headphone output but nothing at the jack output. If I cycle the power with only this output plugged in I can hear the same little pop I get from all the other outputs in the same situation. Anybody else had this issue? If so where do I start to take it to pieces, I'm guessing it's a ribbon cable?
