PCC®-130
The Crown®PCC®-130 is a surface-
mounted small cardioid microphone
of professional quality. This handsomely
styled unit is appropriate for use on the most
elegant boardroom table or lectern. Other ap-
plications include churches, courtrooms and
teleconferencing.
With its small size, the PCC-130 is less con-
spicuous on a conference table than comparable
mics. Because of its highly directional pickup
pattern, the PCC-130 minimizes background
noise and feedback.
The microphone uses the principle of phase co-
herency achieved by mounting a small-diameter
mic capsule very near a boundary. Direct and re-
flected sound waves arrive at the mic in-phase,
and add coherently. This enhances sensitivity,
clarity and reach.
Self-contained electronics eliminate the need for
an in-line power module. Powered by 12-48V
phantom power, the PCC-130 has a low-imped-
ance balanced output which permits long cable
runs without hum pickup or high-frequency
loss. Included with each PCC-130 is a 15-foot
(4.6-m), two-conductor shielded microphone
cable with a TA3F connector (mic end) and 3-pin
male XLR-type connector (output). Although
the standard connector on the microphone is
a Switchcraft TB3M, the microphone can be
special-ordered with a ¼-inch stereo phone plug
on the bottom of the base plate as the PCC-
130SPP.
Capable of withstanding up to 120 dB SPL with-
out distortion, the PCC-130 will never overload
in practical use. Its electret-condenser capsule
provides a wide, smooth frequency response
from 50 Hz to 20 kHz. RFI suppression is in-
cluded. Self-noise is low and sensitivity is very
high. A bass-tilt switch allows the user to tailor
the low-end response for particular applications.
Permanent mounting is enabled by screw holes
in the base. Engineering attention-to-detail has
assured years of reliable use from this trouble-
free microphone.

cal (0 dB = .0002 dyne/cm2), A-weighted.
S/N ratio: 72 dB at 94 dB SPL.
Maximum SPL: 120 dB SPL produces 3% THD.
Polarity: Positive pressure on the diaphragm
produces positive voltage on pin 2 with respect
to pin 3.
Operating voltage: Phantom power, 12 to 48 volts
DC on pins 2 and 3 with respect to pin 1.
Current drain: 4 mA nominal.
Safe operating temperature range: –10° to +50° C,
or +14° to +122° F.
Connector: Switchcraft TB3M in model PCC-130.
Bottom-mounted ¼-inch stereo phone plug in
model PCC-130SPP. See Fig. 4.
Cable: 15-foot, black, two-conductor shielded cable
with Switchcraft TA3F and A3M connectors. No
cable supplied with SPP option.
Switch: Slide switch for bass cut, bass boost, or flat.
Materials: High-impact molded plastic and steel
mesh grille.
Finish: Satin black.
Net weight: 3.5 oz. (99 g). Mic and cable: 9.5 oz.
(269 g).
Dimensions: See Fig. 5.
Optional accessories: Crown PH-1A phantom
power supply (single channel, battery or AC
adapter powered).
*1 pascal = 10 dynes/cm2= 10 microbars = 94 dB SPL.

Frequency in Hz
The bottom of the microphone features a three-
position BASS-TILT switch: FLAT, CUT, and
BOOST. Low-frequency response is adjustable
as shown in Fig. 1.
Installation
Typical placement for each microphone is at
arm’s length from the user. Either place one
microphone in front of each person or one be-
tween every two people. The front of the micro-
phone is indicated by an arrow on the bottom of
the base plate.

If the microphone is used on a lectern, place it
on an open surface, not in a cavity. Otherwise
the frequency response and polar pattern will
be degraded. Set BASS-TILT to BOOST.
The PCC includes two keyhole slots in its base
to accept mounting screws for permanent
mounting. To screw the PCC to a table top, fol-
low this procedure:
1. Punch out the keyholes marked on the label
underneath the base plate (use a razor blade,
small screwdriver, etc.).
2. Using the template below (Fig. 6), mark the
location of two holes in the table where you
want to mount the mic. These holes are 1.6
inch (4 cm) apart, center-to-center. They are
1.56 inches (3.96 cm) from the rear of the mic.
3. Screw two #8 woodscrews (0.27-in. or
7-mm diameter head) into the table at the
locations you marked.
