The Crown PCC
®
-170 is a surface-mounted supercar-
dioid microphone of professional quality. This handso-
mely styled unit is appropriate for use on the most ele-
gant boardroom table or lectern. Other applications
include churches, courtrooms and council chambers.
Because of its highly directional pickup pattern, the
PCC
®
-170 minimizes background noise and feedback.
The microphone reproduces the voice with a clean,
clear and natural sound.
The mic capsule is small enough to ensure phase
coherency up to the highest frequencies in the audible
spectrum, resulting in a wide, smooth frequency
response free of phase interference. Clarity and reach
are also enhanced. RFI suppression is included.
Self-noise is low and sensitivity is very high and an
RFI suppression is included. A bass-tilt switch
allows the user to tailor the low-end response
for particular applications.

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 con-
figured 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 micro-
phone 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.
