Crown PCC130 Surface Mount Boundary Microphone

The Crown PCC130 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 applications include churches, courtrooms and teleconferencing. With its small size, the PCC-130 is less conspicuous 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 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 PCC-130 has a low impedance 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).

Capable of withstanding up to 120 dB SPL without 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 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 bottom of the microphone features a three-position BASS-TILT switch: FLAT, CUT, and BOOST. Low-frequency response is adjustable.
