Press and release an input button to select an input. The output buttons

the audio level.
5.
Press and release the Audio button to exit the Audio mode. The Audio button
stops blinking.

Pressing the Enter or Preset button also exits Audio mode. Pressing the
Preset button changes to Recall Preset mode.
•
There is one audio level setting per input. The audio level setting is
shared by the left and right audio inputs.
•
The audio level settings are stored in non-volatile memory. When power
is removed and restored, the audio level settings are retained.
•
Exiting Audio mode by pressing the Audio button always returns the I/O
configuration to RGBHV (CrossPoint 450 Plus switchers) or video
(MAV Plus switchers) and audio selected for configuration.
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 3-36.
•
Switchers with 16 output buttons — Each output button indicates 1 dB when
blinking and 2 dB when lit. See the table on page 3-37.
•
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 3-37.
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.
