Neumann U87Ai Multi Pattern Condenser Microphone

The U 87 has been the standard of the recording industry since 1967. This microphone is famous for its warm sound and well balanced characteristics. The current U87A yields a 6dB improvement in signal-to-noise over its predecessor. It is equipped with a LF roll-off switch to reduce proximity effect and a 10dB pad. Used extensively for vocals and orchestras, the U87A is also particularly suited for cello, brass, piano, and percussion.
