Silence Detector
General
The DATEQ SD-1 has been designed for activating backup-units if the regular audio signal fails.
The SD-1 is equipped with opto-coupler outputs to start and stop the connected backup-devices and
an alarm-output to which a telephone-dialler can be connected. Parallel to the alarm-output the SD-1
comes equipped with a solid-state relay. This makes it possible to switch on and off the mains supply
of the backup-devices.
With trimmers at the back of the silence detector the start and stop delay and the no-audio detection
level can be adjusted. The backup input has a gain-trimmer. With the internal dip-switches various
switching patterns can be selected to start and stop the backup-units. Furthermore it is possible to
enable an internally trimmable pilot-tone detection and to select a different timing mode. By pressing
the bypass switch at the front the main-input will be selected.
