This is a new mic, was a showroom mic. Never used. Never register. Neumann U87 Ai Shockmount, Microphone With Box EA 87 Elastic Shock Mount Wooden Jeweler's Case Neumann U 87 Ai Set Z - Nickel w/Shockmount With it’s wide range of features and incredible versatility, it is little wonder that the Neumann U87 Ai has been a standard in the recording industry since 1967. Immediately recognizable by it’s distinctive design, the U87 Ai is warm and well balanced providing the perfect tone for speech and vocals but is also equally effective for recording in orchestral or single instrumentalist settings. In the studio, on the stage, for broadcasting, film or television- The Neumann U87 Ai is a general purpose powerhouse that should be in every engineers wheelhouse. High quality set includes shock mount and deluxe wooden case Variable large diaphragm microphone Pressure-gradient transducer with double membrane capsule The studio microphone classic Three directional characteristics: omni, cardioid, figure-8 Switchable low frequency roll-off Switchable 10 dB pre-attenuation Ideal as main and as support microphone in the most differing recording situations For universal use The classical studio mic for vocalists (soloists and background vocalists) Announcer's mic for broadcasting, dubbing, voice-over Use as an Overhead Spot mic for wind instruments, strings (especially cello and double bass), piano, percussion Applications The U 87 Ai condenser microphone is a large diaphragm microphone with three polar patterns and a unique frequency and transient response characteristic. Users recognize the microphone immediately by its distinctive design. It is a good choice for most general purpose applications in studios, for broadcasting, film and television. The U 87 Ai is used as a main microphone for orchestra recordings, as a spot mic for single instruments, and extensively as a vocal microphone for all types of music and speech. Acoustic features 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. Polar patterns The dual-diaphragm capsule is elastically mounted and protected by a large headgrille. A switch below the headgrille selects the three directional patterns: omnidirectional, cardioid and figure-8. A window above this switch shows the symbol of the selected characteristic. Electrical features 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. The present-day circuitry increases the operational headroom of the U 87 Ai by supplying the bias voltages for the capsule through a reduced resistance. The result is a higher sensitivity of 10 dB for identical sound pressure levels, and an improved S/N ratio of 3 dB. Filter and attenuation A switch located at the rear attenuates the sensitivity by 10 dB. When this switch is activated, the microphone accepts sound pressure levels up to 127 dB (equivalent to a sound pressure of 45 Pa) without distortion. An additional switch at the rear allows to change the microphone's cutoff frequency. This reduces low frequency interference directly at the input of the microphone amplifier. This setting also compensates for the unavoidable bass boost that occurs with all pressure gradient transducers when they are used at close distance (proximity effect). The cardioid characteristic maintains a smooth frequency response at a distance of 30 to 40 cm, the figure-8 characteristic even at a distance of 15 to 20 cm.
