How do you deal with the extra gain when panned left or right? Just keep everything safely below 0 so you don't have to be concerned with it?
When I mix, I start with the kick drum (95% of the time) and then go from there. So i'm adding a track at a time to the mix, so when I pan a track, there are no extras gains as that track has been mixed with the pan position already set.
When mixing, 99.99% of the time the instruments are panned to a position and the pan position is not moved. So there are no extra 'surprise' peaks. So there really isn't any extra gain. For tracks that I have pan automation on (left to right or right to left), I simply use a volume envelope to subdue it when it reaches the center. But that is not often.
When mixing any project from 2 tracks to 200 tracks, your track faders are set in a way that you should never clip as the more tracks you have, the lower each fader must be.
Does that clear it up??
