Unidirectional Boundary Microphone

Description

The Crown PCC-160 is a surface-mounted halfsupercardioid microphone intended for professional applications on stage fl oors lecterns conference tables and news desks wherever improved gain-before-feedback and articulation are important.

Features

Industry-standard stage fl oor microphone
Phase Coherent Cardioid design prevents coloration
from surface sound refl ections
High output overrides mixer input noise
Half-supercardioid polar pattern rejects the
pit orchestra and offers high gain-beforefeedback
Very rugged
Low profile

Specification

Type: Phase Coherent Cardioid.
Element: Electret condenser.
Frequency response (typical): 50 Hz to 18000 Hz at
30 degrees incidence to surface. See Fig. 1.
Polar pattern: Half-supercardioid (supercardioid in the
hemisphere above the primary boundary).
See Fig. 2 and Fig. 3.
Impedance: 150 ohms nominal (85 ohms actual)
balanced. (Recommended load impedance 1000
ohms or greater.)
Open-circuit sensitivity: 22mV/Pa* (–33 dB re 1
V/Pa*).
Power sensitivity: –31 dB re 1 milliwatt/Pa*/–123
dBm EIA.
Equivalent noise level (self noise): 22 dB typicaL (0
dB = .0002 dyne/cm2) A-weighted.
S/N ratio: 72 dB at 94 dB SPL.
Maximum SPL for 3% THD: 120 dB SPL.
Polarity: Positive pressure on the diaphragm produces
positive voltage on pin 2 with respect to pin
3 of output connector.
Cable: 15-foot black two-conductor shielded cable
with Switchcraft TA3F connector and A3M connector.
Operating voltage: Standard phantom power: 12 to
48 volts DC positive on pins 2 and 3 with respect
to pin 1.
Safe Operating Temperature: –10? to +50? C or
+14? to +122? F.
Current drain: 4 mA nominal.
Materials: All steel body construction.
Finish: PCC-160: black. PCC-160W: off-white.
Net weight: 11.5 oz. (326 g).
