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

In figure 45, figure 46, and figure 47, the lit or blinking input buttons indicate 41.5 percent of the applied audio input. The unlit input buttons indicate an audio volume attenuation of 39 dB.

The input buttons display the audio volume level of the selected output.

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.

Figure 45. Select Output 1

Figure 46 shows the same volume (41.5%) as figure 45, but displayed on a 16-input- button switcher, such as a MAV Plus 1616 HDA.

•The input LEDs display the selected output's audio volume level.

•In this example, the lit or blinking input buttons indicate 41.5 to 44.5 percent of the applied audio input.

•The unlit or blinking input buttons indicate an audio volume attenuation of 37 dB to 39 dB.
