In the example here (and also correlating to the example on the previous page), Audio Silence Event 1 is set to trigger if audio
on Emb Ch 3 thru Ch 6 falls below the selected threshold for an interval exceeding the selected threshold (for example, a
reversion to stereo audio instead of 5.1-channel audio).
If Audio Silence Event as a trigger condition is not desired, it can be set to Don’t Care on the Event Based Loading sub-tab, or
globally set to Disabled here.
Failover controls set the conditions that comprise a silence event, and also a transition back to an untriggered condition with
resumption of audio for the selected embedded channels.
• If the selected channels maintain levels above the selected Audio Failover Threshold, no triggering is invoked.
• If these channels fall below the selected threshold for period specified by the Primary to Secondary Holdoff control, the
respective Audio Silence Event trigger (condition C) goes true.
• Secondary to Primary Holdoff control sets the time in which the trigger is revoked upon an event false condition.
Note: Default threshold and holdoff settings shown here are recommended for typical use.
