Yeah, a switch box is probably the best solution for now. When I get around to adding audio pass-through, you will hopefully be able to route your audio into Mixxx and out back into your mixer unimpeded. In Mixxx's "options" menu at the top, there's an option to enable vinyl control. If this is unchecked, Mixxx won't react to any incoming signal, timecode or otherwise. So, no, if you send music into Mixxx and you have vinyl control disabled, it won't freak out. :) > Switch boxes can cause sound degradation.

In the lab (ie. my bedroom), yes. In the vinyl control preferences pane, there's this "turntable input preamp" slider which applies a software preamp to the signal. This will allow you to boost your phono-level signals to line-level signals inside Mixxx, without the need for a hardware preamp (props to John Sully for thinking of this). As I said earlier though, this works well in my bedroom - I haven't tested it in a live situation where there's going to be tons of bass rumble and another noise on the signal. I would expect that any noise would be exactly the same as if the turntable or hardware preamp did the amplification, so it would be good if someone could test this out with their bass/speakers cranked.
