T he Crown ® PCC-130SW is a surface-
mounted supercardioid microphone of
professional quality. This handsomely
styled unit is appropriate for use on the most
elegant boardroom table or lectern. Other appli-
cations include distance learning, teleconferenc-
ing, courtrooms and council chambers.
The PCC-130SW has a silent-operating mem-
brane switch which is normally off. The switch
can be confi gured for touch on/off, momentary
on or momentary off. This confi guration is set
by a bottom-mounted slide switch. A high-in-
tensity LED lights when the unit is on. The PCC-
130SW is intended for multiple-microphone use
on a conference table where each person wants
control of his or her microphone. A ¼-inch
(6.35-mm) stereo phone-plug option is avail-
able as the PCC-130SW/SPP.
The microphone attenuates 70 dB when the
switch is in the off position. Since the micro-
phone capsule is placed on a boundary or
surface, direct and refl ected sounds arrive at the
diaphragm in-phase 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. Powered by 12-48V phantom
power, the PCC-130SW has a low-impedance
balanced output which permits long cable runs
without hum pickup or high-frequency loss. A
15-foot (4.6-m), two-conductor-shield micro-
phone cable is included 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 mi-
crophone can be special-ordered with a ¼-inch
(6.35-mm) stereo phone plug on the bottom of
the base plate as the PCC-130SW/SPP.
RFI suppression is included. 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.
Membrane Switch
The PCC-130SW membrane switch can be
confi gured to work three ways:
1. Touch on/off. Touch the switch to turn on
the mic; touch it again to turn off the mic.
2. Momentary on. Touch and hold the switch to
turn on the mic momentarily. Release the switch
to turn the mic back off.
3. Momentary off. Touch and hold the switch
to turn off the mic momentarily. Release the
switch to turn the mic back on. This option
serves as a cough button or privacy button.
After choosing the option you prefer, set the
slide switch according to the label on the bot-
tom of the microphone (see Fig. 5). The LED in
the microphone housing will light when the mic
is on.
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-supercardioid (supercardioid in
the hemisphere above the primary boundary). See
Figs. 2 and 3.
Impedance: 150 ohms, 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 = 0.0002 dyne/cm 2 ), A-weighted.
S/N ratio: 72 dB at 94 dB SPL.
Maximum SPL: 120 dB SPL produces 3% THD.
Off attenuation: 70 dB at 1 kHz.
Turn-on time: 250 msec.
Turn-off time: 125 msec.
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: 6 mA nominal.
Operating temperature range: –10° to +50° C, or
+14° to +122° F.
Connector: Switchcraft TB3M in model PCC-130SW.
Bottom-mounted ¼-inch (6.35-mm) stereo
phone plug in model PCC-130SW/SPP. See Fig. 7.
Cable: 15-foot (4.6-m), black, two-conductor-shield-
ed cable with Switchcraft TA3F and A3M connec-
tors. No cable supplied with SPP option.
Materials: High-impact molded plastic and steel
mesh grille.
Finish: Black.
Net weight: 6 oz. (170 g).
Dimensions: See Figs. 4 and 7.
Optional accessories: Crown PH-1A phantom power
supply (single channel, battery or AC adapter
powered).
*1 pascal = 10 dynes/cm 2 = 10 microbars = 94 dB SPL.
