The design of the microphone is a registered design of the Georg Neumann GmbH in certain countries.

he U 87 is probably the best known and most widely used Neumann studio micro- phone. It is equipped with a

large dual-diaphragm capsule with three directional pat- terns: omnidirectional, car- dioid 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 fre-quency response can be reduced to compensate for proximity effect.

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.

Features

•Variable large diaphragm microphone

•Pressure-gradient transducer with double membrane capsule

•The studio microphone classic

•Three directional characteri- stics: 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

The frequency response of the cardioid and figure-8 directional characteristics are very flat for frontal sound inci- dence, 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.
