Neumann U87Ai Condenser Microphone – Nickel (Used)
Immaculate, unused open box example. A few very small marks to wooden box, otherwise perfect condition. Includes wooden box and full manufacturers warranty.
The Neumann U87ai 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.
