  • The Crown® PCC®-170SW is a surface-mounted supercardioid 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 council chambers. The PCC-170SW has a silent-operating membrane switch which is normally off. The switch can be configured for touch on/off, momentary on or momentary off operation. This configuration is set by a bottom-mounted DIP switch. A high-intensity LED lights when the unit is on.

    Features:

    • Perfect for multimiking applications in telecon- ferencing, distance learning, and boardrooms
    • Phase Coherent Cardioid® design prevents coloration from surface sound reflections
    • Half-supercardioid polar pattern reduces ambient noise and room reverberation
    • Programmable on/off membrane switch
    • Balanced XLR output

    The PCC-170SW is intended for multiple- microphone use on a conference table where each person wants control of his or her microphone. 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 inter- ference. 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-170SW has a low-impedance balanced output which permits long cable runs without hum pickup or high-frequency loss. Although the standard connector option is a Switchcraft TB3M, the microphone can be spe- cial-ordered with a 1?4-inch (6.35-mm) stereo phone plug on the bottom of the base plate as the PCC-170SWSPP. 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.
