Operating Instructions
Unbalanced operation: If you are using a phantom
power supply that does NOT include an isolation
transformer, and you desire an unbalanced output,
use pin 2 as hot and pin 1 as ground. This proce-
dure prevents distortion in the PCC circuit. Do not
unbalance the output of the supply by connecting
pin 3 to pin 1. If you are using a phantom supply
containing an isolation transformer (such as the
Crown PH-1A AC/Battery Supply), then you can
unbalance the output by connecting pin 3 to pin 1
in the cable feeding the mixer. This results in 6 dB
more sensitivity.
The PCC includes two keyhole slots in its base to
accept mounting screws. To screw the PCC to a
surface, refer to Fig. 4 and Fig. 5.
Note: The porous foam liner in the housing must
go toward the front of the microphone; the dense
foam liner goes toward the rear. Otherwise the
frequency response and polar pattern will be
degraded.
Placement suggestions for the PCC-160 are in the
Crown Boundary Microphone Applications Guide
and Speech Sound Reinforcement Application
Guide, available online at http://www.crownaudio.
com/mic_web/mic-library.htm.
BASS TILT SWITCH: On the bottom of the micro-
phone is a bass-tilt switch which allows the user to
tailor the low-end response for particular applica-
®
tions. In general, use the FLAT position. Use the
CUT position to reduce room rumble and air-han-
dler noise. Use the BOOST position to compensate
for low-frequency losses when the PCC is placed
on small boundaries such as lectern shelf-tops.
Architects’ & Engineers’ Specifi cations
The microphone shall be the Crown Model
PCC-160 (black) or PCC-160W (off-white). The
microphone shall be a half-supercardioid electret
condenser type, utilizing a subminiature trans-
ducer of rugged construction. A smooth frequency
response from 50 Hz to 18,000 Hz shall be ob-
tained, with a uniform off-axis response, over 20
dB down at the rear nulls. The microphone will
exhibit excellent off-axis response and gain-be-
fore-feedback.
The microphone shall employ the principle of
phase coherency achieved by mounting a small-
diameter element very near a boundary, thus
eliminating comb fi ltering in the audible spectrum.
A 15-foot (4.6-m), two-conductor shielded cable
with TA3F and A3M connectors shall be supplied
with the microphone.
The microphone shall have a sensitivity of 22
mV/Pa*. The microphone shall accept a 120
dB SPL input while providing no greater than 3
percent THD (open-circuit termination). Equivalent
noise shall be 22 dBA typical. The Crown Model
PCC-160 is specifi ed.
