Neumann U87 Ai - B-Stock

The Neumann U87 Ai is a large dual-diaphragm, multi-pattern condenser microphone in a nickel finish. It comes in a wooden box with the EA87 elasticated shock mount. The U 87 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.

The Neumann U87 presents a wide range of features and versatility that make it to one of the most desirable mics available. Well-known for its warm and well balanced characteristics - your perfect choice as vocal microphone for all types of music and speech. The usage as main microphone for orchestra recordings or as spot mic for single instruments make it the most general-purpose microphone - in studios, for broadcasting, film and television.
