Example 11: Viewing and adjusting an output volume level

The following steps show an example in which the audio output volume is viewed and adjusted. The steps show the front panel indications that result from your action.

Audio output volume is displayed differently on different models. See the table on page 3-43.

Figure 3-70 and figure 3-73 show the indications displayed on a switcher with 16 input buttons.
