Audio Detect Events Setup Controls
(Option +QC only) Sets audio level screening and
thresholds for audio silence/presence event alerts on
embedded and/or AES discrete audio in. When an
audio events occur, the event(s) can be used by the
Events Setup function to invoke input routing or other
changes.
Table 3-2 9902-UDX-FS Function Menu List — continued
Any combination of embedded and AES input channels can be selected to be screened for silence or presence. In the example
here, Audio Detect Event 1 is set to trigger if audio on any of channels Emb Ch 1 thru Ch 6 fall below the selected threshold
for an interval exceeding the selected threshold. Status indicators for each channel show silence (S) / presence (P) status based
on the configured thresholds.
Up to eight independent audio silence/presence events can be set to be screened (with descending priority of consideration from
Event 1 down to Event 8). This status here can be propagated to the Event Setup > Event Triggers sub-tab controls to issue a
GPO, preset engage, or other command when audio silence events are detected.
• Audio Failover Threshold sets the dBFS level at which channel content is considered to be silent, and correspondingly 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.
• Trigger Holdoff sets the period of time in which selected channel silence must occur before an Audio Silence Event trigger
goes true.
• Release 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.
• “Don’t Care” setting may be labeled as Don’t Care, DC, or DSBL (disabled). All notations mean ignoring the channel
from event triggering.
• Selections other than Don’t Care work as an AND function. Where multiple selections are set, a true (trigger)
condition is not propagated unless all selected channels experience the configured criteria.
(In the example shown above, both channels Emb Ch 1 and Emb Ch 2 need to experience a Silence event for a
trigger to be propagated.)
