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 compen-
sate for proximity effect.
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.
Acoustic features
The U 87 Ai is addressed from the front, mark-
ed with the Neumann logo.
The frequency response of
the cardioid and figure-8 di-
rectional characteristics are
very flat for frontal sound inci-
dence, even in the upper fre-
quency 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.
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 design of the microphone is a registered design of the Georg Neumann GmbH in certain countries.
