PCC

-160 (Phase Coherent

Cardioid

®

) is a surface-mounted half-

supercardioid microphone intended for

professional applications on stage fl oors, 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-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.

Since the microphone capsule is placed on a
boundary, direct and refl ected sounds arrive at
the diaphragm in-phase. This coherent addition
of direct and refl ected 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.

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 profi le and black fi nish, 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 fi nished 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 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.
