-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-
fl ected 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.
Specifi cations
Type:  Phase Coherent Cardioid
®
.
Element:  Electret condenser.
Frequency response (typical):  50 Hz to 20,000 Hz at 
30 degrees incidence to surface (see Fig. 1).
Polar pattern:  Half-cardioid (cardioid in the hemi-
sphere above the mounting surface). See Figs. 2 
and 3.
Impedance:  150 ohms nominal (85 ohms actual), 
balanced, (recommended load impedance 1000 
ohms or greater).
Open circuit sensitivity (typical):  22 mV/Pa* (–33 
dB re 1 volt/Pa).
Power sensitivity:  –30.5 dB re 1 mW/Pa*. EIA rating 
–125 dBm.
Equivalent noise level (self-noise):  22 dB SPL typi-
cal (0 dB = .0002 dyne/cm
2
), 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 fl at.
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).

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.
