Additionally to the features of
the PCC-170 the PCC-170SW/SWO offer a silent-operating membrane
switch which is normally off. The switch can be configured for
touch on/off, momentary on or momentary off. This configuration is
set by a bottom-mounted DIP switch. A high-intensity LED lights
when the unit is on. The microphones attenuate 70 dB when the
switch is in the off position.
A pair of extra leads in the mic cable allow the PCC-170SWO
isolated remote sensing of the microphone switch closure. In a
typical distance-learning application, a video camera would track
to the person who switched on the microphone. Remote sensing is
done by a patented opto-coupled MOS switching circuit. At the
remote-sensing leads, the resistance goes low when the mic is on.
The microphones attenuate 70 dB when the switch is in the off
position.
