I have been doing some research about Gain staging and how being much more aware of it early on can help you make a clearer mix. I believe I have that concept pretty well down by now, after having studied the theory and doing various mixes. However, after reading about the difference in how the signal math is handled in LE and HD I still had a question in regards to whether I should e.g. use Master Faders for my stems: dialogue, sfx, foley etc.
So far I have been using AUX's for my stem submixes which then route into the Master Fader. At this point I have only performed my mixes in LE, but once I get opportunity to do a final mix on a HD system then I'd like to do it right, spending my time "mixing for the story" not trying to figure out why my busses are clipping or some other arbitrary routing error. Alleviating that is of course part of the mix process, but I think you know what I mean :)
Personally I don't have many problems with clipping, quite the opposite really due to the equipment I'm using, but I have also received stuff from people who just think that headroom is there to be filled up completely, having an average peak level just below clipping, which I think just sucks when you are summing all the channels together. Having said that then I'm curious how the more experienced lot of you route your stuff? Do you use more than one Master fader at the end of a session or do you also use them at the top of your stems or even earlier?
