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