Hi there, I've tested the DX for about 1h30 mins at home, no problem, then I've played about 4 hours in a bar and I had 5 freezes. The music was playing on one deck, it stopped for 5-10 seconds and the screen was frozen. The next day I've played at home again, for about 1h 30mins, no problems at all. Then I took it to an outdoor event, I played there for about 4 hours, no freezes, but when I checked the dropout count file it was shwowing me 194 droputs. I haven't hear any dropout, nor see the dropout light in the software turning yellow or red, but I've seen the limiter light truning on sometimes. After I saw that, I turned the volume down a little.
