Setting the volume during a page
For an external page to duck the SMART Audio system, the room module requires one of the
following:
l
An audio signal at the paging input (even if the page plays on speakers that aren’t part of the
SMART Audio system)
l
A signal at the 6–12V input. This is only a signal and doesn’t result in the page playing over the
SMART Audio system.
When a signal is present at the paging input, the volume of the other SMART Audio system inputs is
automatically lowered the designated amount.
