CrossPoint 300 Matrix Switchers • Operation3-32
For example: When lit steadily, the Input 3 button indicates the following,
depending on the number of input buttons the switcher has:
Switchers 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).
Switchers 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 3-31 to read the volume display.
Example 9: Viewing and adjusting an output volume level
The following steps show an example in which the audio output volume is viewed
and adjusted. The steps show the front panel indications that result from your
actions.
Audio output volume is displayed differently on different models. See the table on
page 3-31. For this reason, figure 3-52 and figure 3-54 show the indications
displayed on a switcher with 16 output buttons without duplicating all of the
actions shown in figure 3-51 and figure 3-53, which show all actions on switchers
with 12 output buttons.
