Neumann KM183-A NX - Omni-Microphone

The Neumann KM 183 A NX is a part of the modular KM A / KM D miniture microphone system from Neumann. The KM183-A NX consists of a KK 183 omnidirectional capsule and a KM A amplifier, both in a nextel finish.

The modular KM A / KM D miniature microphone system is a further development of the successful KM 100 series. The newly developed passive capsule design is available with 8 different directional characteristics, and can be combined modularly as desired with an analog (KM A) or digital (KM D) output stage in accordance with the AES 42 standard. The new, considerably smaller microphone capsules and an extensive program of accessories permit excellent adaptation of the microphone system to a wide range of applications.
