Create a new track (Ctrl-shift-N). Select 'stereo' and choose 'master fader' from the drop down list. This will act as your main fader for the entire session - any effects you put here (like the L3 or metering/analysis plug ins) will have a global effect on the session. Also any fade outs or volume changes made here will be global.

One caveat: Please don't overuse the L3! Use it musically and not just to slam the levels! Thanks!

Hope that helps...
