Guys, I just got my Q16 last Thursday. I’m getting ready to replace my MixWizard with the new mixer and wanted to check signal flow and output before the change over. One thing I noticed: I’m using a small powered speaker (a small Yamaha) and all XLR outs are nice and clean, but when I use either the Alt or 2 Track out, I seem to get a noticeable hiss. This was the case with everything muted and the master all the way down. Any ideas as to why?
