Master Fader Tracks
Master Fader tracks control the overall level of audio paths that are routed to physical output paths. For example, you could have 8 tracks in a project with channels 1–4 routed to Analog Output 1–2 and channels 5–8 to Analog Output 3–4. You could then create two master faders, one to control each of these output pairs.
Master Fader tracks have additional uses (such as controlling submix levels). For more information, see “Using a Master Fader” on page 758.
