Q: 10. Are the line outs 3/4 able to be switchable outputs? For example I use Vmix for streaming and need to be able to send something different to my speakers than what is going to my headphones. So I want to make sure I can route output 3/4 as like just playback and main outputs as the master.

A: Line Outputs 3/4 will output the same audio that is coming from your main monitor outputs 1/2. The reason for outputs 3/4 is primarily for routing to outboard gear like reverb or effects processors and then bring that audio back into your line inputs, to mix with your existing audio. You can also monitor through another pair of monitors using line outs 3/4.
