Example 10: Viewing and adjusting an input audio level

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

Audio gain and attenuation is displayed differently on different models.

•Switchers with 32 output buttons — Each output button indicates 1 dB when lit. See the table on page 3-37.

•Switchers with 16 output buttons — Each output button indicates 1 dB when blinking and 2 dB when lit. See the table on page 3-38.

•Switchers with 8 output buttons — Each output button indicates 1 dB when blinking slowly, 2 dB when blinking quickly, and 3 dB when lit. See the table on page 3-38.

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-button switcher, on a 16-button switcher, and on an 8-button switcher. The 32-button displays show the actions that led up to the display. For simplicity, the 16-button and 8-button figures show the attenuation display only, not the actions that lead up to it.
