The Crown PCC-170 is a surfacemounted 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. Because of its highly directional pickup pattern, the PCC-170 minimizes background noise and feedback. The microphone reproduces the voice with a clean, clear and natural sound. Since the microphone capsule is placed on a boundary or surface, direct and reflected sounds arrive at the diaphragm in-phase. This coherent addition of direct and refl ected waves increases sensitivity 6 dB and prevents phase cancellations. The mic capsule is small enough to ensure phase coherency up to the highest frequencies in the audible spectrum, resulting in a wide, smooth frequency response free of phase interference. Clarity and reach are also enhanced.ppSelf-contained electronics eliminate the need for an in-line preamp. Powered by 12-48V phantom power, the PCC-170 has a low-impedance miclevel 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 specialordered with a 0.25-in. 0.635-cm stereo phone plug on the bottom of the base plate as the PCC-170SPP. The PCC-170W is fi nished in off-white to blend with church altars and other surroundings where the lighter color is appropriate. 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.
