Level meters are vertical bar graphs on which the height of the bar indicates the
amplitude of the audio program in the corresponding input channel. Use the
Audio pop-up menu to change the input and turn on and off the Phase display.
Other meter characteristics such as ballistics, scale units, and program and test
levels are configured through the Configuration menu.
If your instrument is equipped with optional audio features, it can display phase
of one input pair as a Lissajous pattern, and display relative phase on all four
pairs of inputs with correlation meters.
1. Open the audio display in one tile and select an input. (See page 160, To
set up an audio input.)
2. Check the level meter bars for current audio levels, which are displayed
according to the selected meter ballistics. Each bar displays three colors.
(See Figure 82.)
Green – Indicates audio levels below the test level
