MICROPHONE
he AKG/Crown PCC130 is a surface-mounted
miniature cardioid microphone of profes-
sional quality. This handsomely styled unit is
appropriate for use on the most elegant board-
room table or lectern. Other applications include
churches, courtrooms and teleconferencing.
The PCC130 has the same performance as the
PCC170, but is smaller, so it is less conspicuous
on a conference table. Because of its highly direc-
tional pickup pattern, the PCC130 minimizes
background noise and feedback.
The microphone uses the principle of phase
coherency achieved by mounting a small-diameter
mic capsule very near a boundary. Direct and
reflected 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 PCC130 has a low-imped-
ance balanced output which permits long cable
runs without hum pickup or high-frequency loss.
Capable of withstanding up to 120 dB SPL without
distortion, the PCC130 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 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.
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.
The PCC130 SW (right) has a silent-operating
programmable membrane switch that can be
configured for touch ON/OFF, momentary ON
or momentary OFF. A high-intensity LED lights
when the unit is on.
For easy installation, both microphones offer an
XLR connector and a detachable cable.
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 micro-
phone in front of each person or one between
every two people. The front of the microphone 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.
