PCC-160W  
he Crown® PCC®-160 (Phase Coherent  
Cardioid®) is a surface-mounted half-  
supercardioid microphone intended for  
professional applications on stage floors, lecterns,  
conference tables, and news desks—wherever  
improved gain-before-feedback and articulation  
are important.

Features  
Half-supercardioid polar pattern rejects the  
pit orchestra and offers high gain-before-  
feedback  
Very rugged  
Low profile  
Industry-standard stage floor microphone  
Phase Coherent Cardioid design prevents color-  
ation from surface sound reflections  
Similar to the Pressure Zone Microphone®  
High output overrides mixer input noise  
(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-before-feedback, reduces  
unwanted room noise and rejects sounds from the  
rear. Surface-mounting creates a “half-supercardi-  
oid” polar pattern and increases directivity 3 dB.  
Specifications  
Fig. 1 Frequency Response  
Type: Phase Coherent Cardioid.  
Element: Electret condenser.  
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 coher-  
ency 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.  
Frequency response (typical): 50 Hz to 18,000 Hz at  
30 degrees incidence to surface. See Fig. 1.  
Polar pattern: Half-supercardioid (supercardioid in the  
hemisphere above the primary boundary).  
See Fig. 2 and Fig. 3.  
Impedance: 150 ohms nominal (85 ohms actual),  
balanced. (Recommended load impedance 1000  
ohms or greater.)  
Open-circuit sensitivity: 22mV/Pa* (–33 dB re 1  
V/Pa*).  
Power sensitivity: –31 dB re 1 milliwatt/Pa*/–123  
dBm EIA.  
Frequency in Hz  
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.

200 Hz  
4 kHz  
S/N ratio: 72 dB at 94 dB SPL.  
Maximum SPL for 3% THD: 120 dB SPL.  
Polarity: Positive pressure on the diaphragm pro-  
duces positive voltage on pin 2 with respect to pin  
3 of output connector.  
Cable: 15-foot, black, two-conductor shielded cable  
with Switchcraft TA3F connector and A3M con-  
nector.  
Operating voltage: Standard phantom power: 12 to  
48 volts DC positive on pins 2 and 3 with respect  
to pin 1.  
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.  
Safe Operating Temperature: –10° to +50° C or  
+14° to +122° F.  
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.  
Current drain: 4 mA nominal.  
Materials: All steel body construction.  
Finish: PCC-160: black. PCC-160W: off-white.  
Net weight: 11.5 oz. (326 g).  
Capable of withstanding up to 120 dB SPL with-  
out 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 distant-miking applica-  
tions. Output impedance is 150 ohms, balanced.  
Dimensions: See Fig. 5.  
Optional accessories: Crown PH-1A phantom  
power supply (one channel, battery or AC-adapter  
powered).
