Crown PCC 160 Boundary Mic
The Crown® PCC®-160 (Phase CoherentCardioid®) is a surface-mounted half-supercardioid microphone intended forprofessional applications on stage floors, lecterns,conference tables, and news desks—wherever improved gain-before-feedback and articulation are important.
Similar to the Pressure Zone Microphone®(PZM®), the PCC is designed to be used on arelatively large boundary surface. Unlike the PZM,the Phase Coherent Cardioid uses a subminiature supercardioid mic capsule. Its directional polar pattern improves gain-before-feedback, reduces unwanted room noise and rejects sounds from the rear. Surface-mounting creates a “half-supercardioid”polar pattern and increases directivity 3 dB.Since the microphone capsule is placed on aboundary, direct and reflected sounds arrive at the diaphragm in-phase. This coherent addition of direct and reflected 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 frequencyresponse free of phase interference. Clarity and reach are also enhanced.
Self-contained electronics eliminate the needfor an in-line preamp box. The PCC-160 can be phantom powered directly from the console orother remote power source providing 12 to 48 volts. If battery power is required, a battery supply unit can be inserted anywhere in the mic line right up to the console or mixer. A “bass tilt” switch allows the user to tailor the low-end response for particular applications.
Thanks to its low profile and black finish, the microphone becomes almost invisible in use. A side-mounted connector complements the formfactor of the PCC-160, allowing the unit to be placed effectively at the stage edge, at the top of a lectern or in other tight spots. If desired, the cable can be hard-wired for bottom entry.
The heavy-gauge, all steel body protects the unitfrom accidental abuse. Permanent mounting isenabled by screw holes in the base. Engineeringattention-to-detail has assured years of troublefreeuse from this reliable microphone.
Capable of withstanding up to 120 dB SPL withoutdistorting, the PCC-160 will never overloadin practical use. Its electret condenser capsule provides a wide, smooth frequency response from50 Hz to 18 kHz. RFI suppression is included.Self-noise is low, and sensitivity is very high tooverride mixer noise in distant-miking applications.Output impedance is 150 ohms, balanced.
