Example 11: Viewing and adjusting an output volume level
In the following example, 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 3-46.
N Because of the different volume display schemes, the output volume levels that
result from the following example are shown three times: as displayed on a
32-input button switcher, on a 16-input button switcher, and on a 12-input
button switcher. The 32-button displays show the actions that led up to the
display. For simplicity, the 16-button and 12-button figures show the volume
display only, not the actions that lead up to it.
