PCB uses only the highest quality material and components for its microphones.
The EX378B02 is an INDUSTRY EXCLUSIVE prepolarized condenser microphone system.
Preamplifiers allow high impedance signals to be converted to low impedance signals.
PCB’s phantom powered preamplifier (426A14) has a unique convertible design that mates with any ½” or ¼” prepolarized IEC 61094-4 compliant microphone cartridge.
Model 378B11 is a 1/2 in (12 mm) prepolarized microphone and preamplifier high sensitivity system, with the capability of measuring very low amplitudes due to its low noise floor (16 dBA). This mated pair can measure sound pressure levels to 137 dB within a 3% distortion rating.
Model 378C13 is a 1/2 in (12 mm) prepolarized microphone andpreamplifier system featuring an enhanced upper dynamic range(150 dB) which minimizes overloading. This model also featuresan extended frequency range covering the 20 kHz audible range.Previously, these applications required a 1/4 in microphonesystem which is both higher in price and not as desirable forinherent noise.
