Example 11: Viewing and adjusting a analog 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
table 4 on page 70).
Because of the different volume display schemes, the output audio levels that result from
the following example are shown three times:
• As displayed on a 32-input button switcher
• As displayed on a 16-input button switcher
• As displayed on a 12-input button switcher.
The 32-button displays show the actions that lead up to the display and the display itself.
For simplicity, the 16-button and 12-button figures show the volume display only, not the
actions that lead to it.
1. Clear all selections: Press and release the Esc button.
2. Select Audio mode: Pr ess and hold the Audio button for approximately 2 seconds
until it blinks.

attenuation of 39 dB.

Each lit input button beyond input 1 indicates 3 percent of the total input volume is
applied to the output. The flashing button indicates an additional 1.5 percent.
In this example, the lit input buttons indicate 41.5 percent of the applied audio
input. The unlit input buttons indicate an audio volume attenuation of 39 dB.
