CloseYou'll LOVE This U 87 Package!
The Neumann U 87 is arguably the best known and most widely used studio microphone in the world (for good reason). The U 87 Ai condenser microphone is a large diaphragm microphone with three polar patterns and a one-of-a-kind frequency and transient response characteristic. A distinctive design and mythical Neumann sound make this microphone a must-have for pro studios. The U 87 is known for its one-of-a-kind frequency and transient response characteristics which deliver a smooth natural sound with a wide range of source material. The U 87 Ai is used as a main microphone for orchestra recordings, as a spot microphone for single instruments, and extensively as a vocal microphone for all types of music and speech. The easy-to-recognize U 87 is a classic!Neumann U 87 Ai At-a-Glance:
- Filter and Attenuation
- Updated Parts
- Natural Response
- Selectable Polar patterns
Natural Response
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 totally flat for frontal sound incidence, even in the upper frequency range. By means of a high-pass filter interferences through subsonic and low frequencies are reduced remarkably.
Selectable 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.
Updated Components
The letter A in the name indicates a more recent generation, as compared to the U 87 i microphones that were made from 1967 to 1986. Modifications apply to the electronic parts 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 better 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 works with sound pressure levels up to 127 dB (equivalent to a sound pressure of 45 Pa) without distortion. An more switch at the rear allows to change the microphone's cutoff frequency. This reduces low frequency interference straight at the input of the microphone amp. 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.
