PCC®-130SW

The Crown® PCC-130SW is a surface- mounted supercardioid microphone of professional quality. This handsomely

PHASE COHERENT CARDIOID® MICROPHONE

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 configured for touch on/off, momentary on or momentary off. This configuration 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

Features

•Ideal for boardrooms, distance learning, teleconferencing, courtrooms, council chambers

•Mounts on a table top

•Elegant styling and small size

•Programmable membrane switch can be programmed for touch on/off, press to talk or press to mute

•LED light indicates when unit is on

•Clear, natural sound quality

•Half-supercardioid polar pattern reduces muddy-sounding room acoustics and

background noise

(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 reflected 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 configured 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.

Specifications

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).

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/cm2), 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.
