Example 8: 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 actions.
Audio gain and attenuation is displayed differently on different models. See the
table on page 3-26.
• Switchers with 16 output LEDs — Each output LED indicates 1 dB when
blinking and 2 dB when lit.
• Switchers with 8 output LEDs — Each output LED indicates 1 dB when
blinking slowly, 2 dB when blinking quickly, and 3 dB when lit.
For this reason, figure 3-45 and figure 3-47 show the indications displayed on a
switcher with 16 output buttons without duplicating all of the actions shown in
figure 3-44 and figure 3-46, which show switchers with 8 output buttons.
