Example 9: Viewing and adjusting an input audio level

NOTE: This procedure can only be performed if the audio/RS-232 wire pair of the input is defined as audio (see ”Defining the Audio/RS-232 Wire Pair” on page 62).

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-output button switcher

•As displayed on a on 16-output button switcher

•As displayed on a 8-output button switchers

The 32-button drawings show the actions that led up to the display. The 16-button and

8-button drawings show the gain or attenuation display only, not the actions that caused it.

In the following example, an audio level is viewed and adjusted. The steps show the front panel indications that result from your action.

1.Clear all selections: Press and release the Esc button.
