Basic Mixing : Master Fader Tracks and Signal Flow : Common Uses for Master Faders
 
Common Uses for Master Faders
Master Faders can be used to:
Control and process output mixes
Monitor and meter an output (such as a bus or hardware output) to guard against clipping
Control submix levels
Control effects sends levels
Control submaster (bussed tracks) levels
Apply dither or other inserts to an entire mix
Use Master Faders to control submix levels, send level masters, and other outputs. Master Faders can control either output or internal busses. You can use a Master Fader track assigned to an Output path as a master volume control. You can also use a Master Fader track assigned to a bus to trim the inputs to Auxiliary Input tracks for submixes to avoid clipping.
