Master Volume Controls

A master volume is a control that adjusts multiple sub‑controls, and is used to set a listening
level that is appropriate for the end‑user. In the illustration below, master volume controls
are color‑coded to associate the master control with the sub‑controls that are affected. In
this case, all of the sub‑controls are points in the mix matrix, or "mix‑points." Master Volume
controls shown are as follows:
