Master Volume Controls - Extron electronics MediaPort 200 User Manual

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 figure 7 below, master volume controls are
color-coded to associate the master control with the sub-controls that are affected and
can be found in the
page 56). In this case, all of the sub-controls are points in the mix matrix, or "mix-points."
Master Volume controls shown are as follows:
