DAPL031
DAPL 031 The differential adapter for conductive lines
-
The differential adapter for conductive lines in the speech range of frequencies (DAPL 031) is intended for use together with ST 031 "Piranha" and ST 031P.
DAPL 031 ensures:
• the detection of furtive data acquisition means that use conductive lines for signal transmission;
High sensitivity of the device and a symmetrical adapter input make it possible to reveal:
• signals from active and passive (non equipped with power supply) microphones;
• microphone modulation from office and home equipment (TV's, VCR's, hi-fis etc.); security and fire alarms, etc., in the conductive line.

DAPL 031 is connected to the "PROBES" connector of main control processing and idication unit.
With connecting of DAPL 031 to main control processing and indication unit the ACOUSTIC CHANNEL mode of operation is initiated.
ATTENTION!!!
Maximum allowable input voltage 70V!
