Silence Sense Alarm
The SMARTCASTER can be equipped with a Silence Sense Alarm to start the SMARTCASTER back up
when 30 seconds of silence is detected. In some systems, the Silence Sense can be wired to trip the
SMARTCASTER into starting again. In other systems, the Silence Sense must be wired to actually reset
the computer.
In all cases, it is important to remember that the Silence Sense must always have audio being fed to it.
If audio is not present, the Silence Sense will activate. If the station does not have a 24 hour operation,
please call our support line so that we can help program the SMARTCASTER to loop through some
instrumentals during the period the station is off the air.
Stick-On Silent Sense
To wire the Silence Sense, simply connect the provided 24 VDC power supply to the ‘PWR IN’ inputs on
the Silence Sense. Connect audio from the program channel of the console to the ‘INPUT’ terminals of
the Silence Sense. (This can be unbalanced or balanced.) It is not recommended that the
SMARTCASTER output be used for the audio input to the Silence Sense. There are times when other
types of audio go over the air, and SMARTCASTER is silent, (Ex: Mic, CD players, etc.).
Next, on the underside of the Silence Sense is a circuit board. Use the reset terminals soldered to this
board to restart the SMARTCASTER.
