Description: Neumann's U 87 Ai presents a wide range of features and versatility that make it a highly desirable microphone. Well-known for its warm and well balanced characteristics - the U 87 Ai is a great choice for a vocal microphone for all types of music and speech. The U 87 Ai works well as a main microphone for orchestra recordings, or as spot mic for single instruments, making it the most general-purpose microphone - in studios, for broadcasting, film and television. The U 87 Ai is equipped with a large dual-diaphragm capsule with three directional patterns: omnidirectional, cardioid and figure-8. These are selectable with a switch below the headgrille. A 10 dB attenuation switch is located on the rear. It enables the microphone to handle sound pressure levels up to 127 dB without distortion. Furthermore, the low frequency response can be reduced to compensate for proximity effect. The U 87 Ai is addressed from the front, marked with the Neumann logo. The frequency response of the cardioid and figure-8 directional characteristics are very flat for frontal sound incidence, even in the upper frequency range. The microphone can be used very close to a sound source without the sound becoming unnaturally harsh. By means of a high-pass filter interferences through subsonic and low frequencies are reduced remarkably. The letter A in the name indicates a more recent generation, as compared to the U 87 i microphones that were built from 1967 to 1986. Modifications apply to the electronic components of the microphone only; the capsule remained unchanged.IncludesU 87 Ai multipattern microphoneEA 87 shockmountWS 87 windscreenIC 3/25 cableWood boxFeaturesVariable large diaphragm microphonePressure-gradient transducer with double membrane capsuleThree directional characteristics: omni, cardioid, figure-8Switchable low frequency roll-offSwitchable 10 dB pre-attenuationIdeal as main and as support microphone in the most differing recordingsituationsSpecificationsAcoustical Operating Principle: Pressure gradient transducerDirectional Pattern: Omnidirectional, cardioid, figure-8 plusFrequency Range: 20 Hz ... 20 kHzSensitivity at 1 kHz into 1 kohm: 20/28/22 mV/PaRated Impedance: 200 ohmsRated Load Impedance: 1000 ohmsEquivalent noise level, CCIR: 26/23/25 dBEquivalent noise level, A-weighted: 15/12/14 dB-AS/N ratio, CCIR (rel. 94 dB SPL): 68/71/69 dBS/N ratio, A-weighted(rel. 94 dB SPL): 79/82/80dBMaximum SPL for THD 0.5%: 117 dB (cardioid)Maximum SPL for THD 0.5% with preattenuation: 127 dBMaximum Output Voltage: 390 mVDynamic Range of the Microphone Amplifier (A-weighted): 105 dBSupply Voltage: 48 V ± 4 VCurrent Consumption: 0.8 mAMatching Connectors: 3-pin XLR-FWeight: 1.1 lbs.Diameter: 2.2"Length: 7.87"
