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.

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

2.Select Audio mode: Press and hold the Audio button for approximately 2 seconds until it blinks.

The output buttons display the audio level and polarity (gain or attenuation) of the selected input.

•Each output button indicates 1 dB when lit.

When the buttons are lit green, they indicate a gain (+) audio level.

When the output buttons are lit red, they indicate an attenuation (-) level.

•In this example, the output buttons display an audio gain level of +8 dB.
