box if you would like to have an automatic source connection change to your specified
secondary source when silence detect is triggered. Check the “Auto Failback” box if you
would like to have an automatic source connection changed to your primary source when
the silence detect function is released.
Finally, you must click on the Apply button at the bottom of the window before any
of your changes will take effect.
Status
The “Status” area of the Silence Detect tab
shows at a glance information about the silence
detect function for the destination signal. The
primary and secondary connection paths are la‑
beled and indicated, and the “L” and “R” audio
level indicators will flicker in the presence of
audio. Note that the currently active signal path
shows in green and the inactive signal path shows
in black. You can click on the Sec button to force a
connection change to the alternate signal path and
a dialog “Manually Switch Output” window will
open asking you to confirm the change.
Warning: Clicking
Yes on the dialog box will
instantly change the audio connection. This button
is meant to be used for initial set up and testing and
for manual failover in cases where automatic failover is not desired, or when the failover
is needed for reasons other than the loss of audio signal.
Logic
Enabling Silence Detection on a Destination automatically creates a new Logic Only
source signal. This signal will appear in the crosspoint grid with a name of “XXXL”
where XXX is the name of the destination using silence detection. This logic signal also
has an ID# of XXXXX4XX where
XXXXX_XX is the signal ID of the
destination.
To use this logic signal to trig‑
ger a physical alarm, create a new
Logic Only destination signal on
the BLADE 3 you will use for the
physical alarm (light, buzzer, etc.)
logic connection. Map the particular
logic pin that you want to use and
select the “SDet Failure” function
from the drop down list.
One you have defined the new
Logic Only destination signal, make a new crosspoint connection between the auto gener‑
ated silence alarm source logic signal and your new alarm destination signal. On detecting
silence, the SDet Failure logic function will trigger your destination alarm signal for as
long as the silence persists.
