The distinctive new BCM104 large-diaphragm condenser mic was designed by Neumann for the most critical broadcast and studio applications. This cardioid microphone will look great in the booth and features a large-diaphragm K07B condenser capsule; an integrated pop screen; and a quick-release head grille for easy cleaning. The BCM104 has an elastic mount protecting against structure-borne noise, that is compatible with standard broadcast microphone arms.Main Features:Large-diaphragm condenser capsuleCardioid directional characteristicCharacteristic, functionally optimized design*Integrated pop protectionIntegrated elastic suspensionIndividual headgrilles for different usersColored rings to identify the replacement headgrillesEasy removal and cleaning of microphone headgrille (with bayonet mount)Mechanical compatibility with standard studio boom armsInternal switches: high-pass and pre-attenuationSpecifications:Acoustical operating principle: Pressure gradient transducerDirectional pattern: CardioidFrequency range: 20 Hz … 20 kHzSensitivity at 1 kHz into 1 kohm: 22 mV/PaSensitivity at 14 dB attenuation: 4.4 mV/PaRated impedance: 50 ohmsRated load impedance: 1 kohmsEquivalent noise level, CCIR1) 18 dBEquivalent noise level, A-weighted1) 7 dB-AMaximum SPL for THD 0.5% with preattenuation2) 152 dBSignal-to-noise ratio, CCIR1) (rel. 94 dB SPL) 76 dBSignal-to-noise ratio, A-weighted1) (rel. 94 dB SPL) 87 dBMaximum output voltage 10 dBuDynamic range of the microphone amplifier (A-weighted) 131 dBSupply voltage (P48, IEC 61938) 48 V 4 VCurrent consumption (P48, IEC 61938) 3.2 mAMatching connector: XLR3FWeight: 500 gDiameter: 64 mmLength: 85 mmHeight: (without suspension) 110 mm
