CARDIOID MICROPHONE

PCC®-130

he Crown® PCC®-130 is a surface- Tmounted 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.

Features		Cardioid pattern reduces background noise and
		feedback
Ideal for boardroom tables, lecterns,	churches,	Prevents phase interference due to table sound
courtrooms and teleconferencing

Small and inconspicuous		Three-position bass-tilt switch

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.

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.

Specifications

Type: Phase Coherent Cardioid®.

Element: Electret condenser.
