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.

Applications
The U 87 Ai condenser microphone is a large
diaphragm microphone with three polar pat-
terns and a unique frequency and transient re-
sponse 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 micro-
phone for all types of music and speech.

The frequency response of
the cardioid and figure-8 di-

The microphone can be used
very close to a sound source
without the sound becoming
unnaturally harsh.
