NEUMANN U 87 Ai i
Features:
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.

• Variable large diaphragm microphone
• Pressure-gradient transducer with double membrane capsule
• The studio microphone classic
• Three directional characteristics: 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
