For example: When lit steadily, the Input 3 LED indicates the following, depending on the number of input buttons the switcher has:

mSwitchers with 12 input buttons — 47 dB of attenuation when compared to the Input 3 LED blinking quickly (48 dB to 50 dB of attenuation). The blinking Input 4 LED (45 dB to 46 dB of attenuation) is at least 2 dB less than the fast blinking Input 3 LED (48 dB – 46 dB) and at most 5 dB less (50 dB – 45 dB).

mSwitchers with 16 input buttons — 52 dB of attenuation when compared to the Input 3 LED blinking (53 dB to 55 dB of attenuation). The blinking Input 4 LED (49 dB to 51 dB of attenuation) is at least 2 dB less than

the fast blinking Input 3 LED (53 dB – 51 dB) and at most 6 dB less (55 dB – 49 dB).

See the table on page 3-32 to read the volume display.

Example 9: Viewing and adjusting an 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 the table on page 3-32. For this reason, figure 3-53 and figure 3-55 show the indications displayed on a switcher with 16 output buttons without duplicating all of the actions shown in figure 3-52 and figure 3-54, which show all actions on switchers with 12 output buttons.
