Settings
You can review the effect of the settings in the
“Status” area of the window. These settings are:
Detector Threshold - This is the signal level
threshold for silence detection. Any time the audio
signal at the destination falls below this threshold,
the BLADE will start to keep track of how long the
signal stays below this threshold level. This setting
should be adjusted to match your station’s format.
Not to be obvious, but a Hot format most likely never
expects to have a low signal level, while a classical
format might frequently do so.
Failed Duration - This is the acceptable length
of time for the signal to be below threshold. It is
only applied when the “Auto Failover” check box
has been set. Again, this setting is very dependant
on your format. If your program material has few,
if any, pauses, and your Talent voices are energetic, you can set the duration as
low as several seconds. Conversely, if your programs have frequent quiet passages
and your Talent voices are relaxed you may need to set the duration as high as the
maximum duration of 45 seconds.
The Navigator GUI can be helpful in arriving at the optimum settings for thresh-
old and duration. In the Status area of the Silence Detect window are two round
indicators labeled “L” and “R.” These are audio indicators that show the left and
right channels of the destination. They will be shown in green when the audio level
is above the threshold setting, and in red when it is below the threshold setting. If
you leave the auto failover box unchecked, you can watch these indicators as you
alter the threshold without danger of losing the audio connection due to a silence
detect triggered failover. Monitor how frequently and for how long the audio is be-
low threshold, add some extra time margin for insurance purposes, and that’s your
settings. Just remember, if your programming or Talent changes, these settings may
need to be readjusted.
Failback Duration - This setting can be very useful. It is only applied when the
“Auto Failback” check box has been set, and represents how long the BLADE will
wait to restore the original source connection. It will monitor the original source
for level, and, if it stays above the threshold for the specified time, will switch back
to the original source. This is useful in situations where the primary connection is
intermittent; by specifying a duration over which the primary connection must “prove
itself good” you can avoiding a premature switch back before the connection is solid.
The other two controls in the “Settings” area of the silence Detect tab are the
previously mentioned check boxes for “Auto Failover” and “Auto Failback.” Check
the “Auto Failover” 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.
