Selling Neumann U87 Ai with Neumann shockmount, comes in original wooden box, Great mic, well looked after, original owner from new.

A Neumann Classic! The U87 is presumably the most famous and most widely adopted studio microphone. 3 polar patterns and switchable preattenuation guarantees versatile application. It is equipped with a large dual-diaphragm capsule, switchable between omnidirectional, cardioid and figure-8.

Features and versatility

The U 87 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.

Pad & low cut

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.

Polar pattern

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.

"Ai"

The letter A in the name indicates a more recent generation, as compared to the U 87 i microphones that were built from 1967 to 1986. Modifications apply to the electronic components of the microphone only; the capsule remained unchanged. The present-day circuitry increases the operational headroom of the U 87 Ai by supplying the bias voltages for the capsule through a reduced resistance. The result is a higher sensitivity of 10 dB for identical sound pressure levels, and an improved S/N ratio of 3 dB.
