Neumann U 89 I Multi-Pattern Mic with K89 Capsule, Five Patterns, Pad, Filter, in Woodbox, Nickel

The Neumann U89I Multi-Pattern Mic with K89 Capsule, Five Patterns, Pad, Filter, in Woodbox | Nickel is a studio microphone for universal applications. The headgrille protects a dual-diaphragm capsule. A rotary switch below the headgrille selects from five different polar patterns. Therefore the microphone can be adapted easily to large sound sources, and those that are spread wide apart, or to sound sources to be recorded at a greater distance.

Key Features

Variable large diaphragm microphone
Pressure-gradient transducer with double membrane capsule
Five directional characteristics: omni, wide angle cardioid, cardioid, hypercardioid, figure-8
Thereby most versatile in all recording situations
Two-stage roll-off filter
Switchable 6 dB pre-attenuation
Extended frequency range in comparison to U 87 A
