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 s e same performance as thehath

PCC170, but smaller, less conspicuousissoitis

on a conference table. Because its highly direc- of

tional pickup pattern, the PCC130 minimizes

background noise and feedback.

The microphone uses e principle of phaseth

coherency achieved by mounting a small-diameter

mic capsule very near a boundary. Direct and

reected sound waves arrive at e c -phase,thmiin

and coherently. This enhances sensitivity, add

clarity and reach.

Self-contained electronics eliminate e need forth

anby -line power module. Powered in -1248V

phantom , e PCC130 s a low-imped- powerthha

ance balanced output which permits long cable

runs without hum pickup or high-frequency loss.

Capable of withstanding up to 120dB without SPL

distortion, the PCC130 will never overload in

practical use. s electret-condenser capsuleIt

provides a wide, smooth frequency response from

50 Hz to 20 kHz. RFI suppression is included. Self-

noise low and sensitivity very high. A bass-tilt isis

switch allows the user tailor the low-end to

response for particular applications.

Permanent mounting enabled screw holes isbyin

the base. Engineering attention-to-detail has

assured years of reliable e from this trouble-free us

microphone.

The PCC130 SW (right) has a silent-operating

programmable membrane switch that can be

congured for touch ON/OFF, momentary ON

or momentary OFF. A high-intensity LED lights

when the unit is on.

For easy installation, both microphones oer an

XLR connector and a detachable cable.

The bottom of e microphone features a three-th

position -TILT switch: FLAT, CUT, BASSand

BOOST. Low-frequency response is adjustable as

shown in Fig. 1.
