PCC-160W
he Crown PCC®-160 (Phase Coherent Cardioid®) is a surface-mounted supercardioid
T
microphone intended for professional
applications on stage floors, lecterns, conference tables, and news desks—wherever
improved gain-before-feedback and articulation
are important.
Similar to the Pressure Zone Microphone
(PZM®), the PCC is designed to be used on a
relatively large boundary surface. Unlike the
PZM, the Phase Coherent Cardioid uses a
subminiature supercardioid mic capsule. Its
directional polar pattern improves gain-beforefeedback, reduces unwanted room noise and
rejects sounds from the rear. Surface-mounting
creates a “half-supercardioid” polar pattern and
increases directivity 3 dB.
Since the microphone capsule is placed on a
boundary, direct and reflected sounds arrive at
the diaphragm in-phase. This coherent addition
of direct and reflected waves increases sensitivity
6 dB and prevents phase cancellations. 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.
Self-contained electronics eliminate the need for
an in-line preamp box. The PCC-160 can be
phantom powered directly from the console or
other remote power source providing 12 to 48
volts. If battery power is required, a battery
supply unit can be inserted anywhere in the mic
line right up to the console or mixer. A “bass tilt”
switch allows the user to tailor the low-end
response for particular applications.
Thanks to its low profile and black finish, the
microphone becomes almost invisible in use. A
side-mounted connector complements the form
factor of the PCC-160, allowing the unit to be
placed effectively at the stage edge, at the top of
a lectern or in other tight spots. If desired, the
cable can be hard-wired for bottom entry.
The PCC-160W is finished in off-white to blend
with church altars and other surroundings
where lighter color is appropriate.
The heavy-gauge, all steel body protects the
unit from accidental abuse. Permanent mounting is enabled by screw holes in the base.
Engineering attention-to-detail has assured
years of trouble-free use from this reliable
microphone.
Capable of withstanding up to 120 dB SPL
without distorting, the PCC-160 will never overload in practical use. Its electret condenser
capsule provides a wide, smooth frequency
response from 50 Hz to 18 kHz. RFI suppression is included. Self-noise is low, and sensitivity
is very high to override mixer noise in distantmiking applications. Output impedance is 150
ohms, balanced.

Operating Instructions
Unbalanced operation: If you are using a
phantom power supply that does NOT include
an isolation transformer (such as the Crown
PH-4B), and you desire an unbalanced output,
use pin 2 as hot and pin 1 as ground. This
procedure prevents distortion in the PCC circuit.
Do not unbalance the output of the PH-4B 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. 3.
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
, available free from your dealer, directly
from the Crown Literature Department or online
at www.crownaudio.com.
BASS TILT SWITCH: On the bottom of the microphone is a bass-tilt switch which allows the
user to tailor the low-end response for particu-
lar applications. In general, use the FLAT position. Use the CUT position to reduce room
rumble and air-handler noise. Use the BOOST
position to compensate for low-frequency
losses when the PCC is placed on small boundaries such as lectern shelf-tops.
Architect’ & Engineers’ Specifications
The microphone shall be the Crown Model PCC160 (black) or PCC-160W (off-white). The
microphone shall be a half-supercardioid electret condenser type, utilizing a subminiature
transducer of rugged construction. A smooth
frequency response from 50 Hz to 18,000 Hz
shall be obtained, with a uniform off-axis response, over 20 dB down at the rear nulls. The
microphone will exhibit excellent off-axis response and gain-before-feedback.
The microphone shall employ the principle of
phase coherency achieved by mounting a smalldiameter element very near a boundary, thus
eliminating comb filtering 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 specified.
