Description Brand: Neumann Model: U 87 Type: Condenser Microphone MPN: Does Not Apply UPC: Does not apply
This U 87 is in very good condition with some signs of normal wear. 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 featuresThe 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 highpass filter interferences through subsonic and low frequencies are reduced remarkebly. Polar patternsThe 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 featuresThe 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 10dB for identical sound pressure levels, and an improved S/N ratio of 3dB.Filter and attenuationA switch located at the rear attenuates the sensitivity by 10dB. When this switch is activated, the microphone accepts sound pressure levels up to 127dB (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.Neumann U 87 Ai Features: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 10dB pre-attenuation Ideal as main and as support microphone in the most differing recording situationsRequires +48V phantom powerItem will be professionally packed, shipped and insured to guarantee safe arrival The item pictured is the one you will be receiving.No additional accessories included. **BUY WITH CONFIDENCE****FREE SHIPPING WITHIN THE UNITED STATES** Tone House Studios has new Guitar and Recording Studio gear being added every week!!
