Example 10: Viewing and adjusting an input audio level
In the following example, an audio level is viewed and adjusted. The steps show
the front panel indications that result from your action.
Audio gain and attenuation is displayed differently on different models.
Because of the different gain and attenuation display schemes, the input audio
levels that result from the following example are shown three times: as displayed
on a 32-button switcher, on a 16-button switcher, and on an 8-button switcher. The
32-button displays show the actions that led up to the display. For simplicity, the
16-button and 8-button figures show the attenuation display only, not the actions
that lead up to it.
