In a word: The Neumann classic. Three directional characteristics and switchable pre-attenuation ensure suitability for a wide range of applications.
The U 87 is probably the best known and most widely used Neumann studio microphone. It is equipped with a large dual-diaphragm capsule with three directional patterns: omnidirectional, cardioid 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 frequency response can be reduced to compensate for proximity effect.
