The KM 183 A from Neumann is an NX Omni Condenser Microphone.

Compared to its predecessor, the Series KM 100, the new system KM A works with passive capsules, which are considerably smaller while retaining the proven acoustic design. New and advanced electronic components allow for many electroacoustic and operational advantages, such as reduced self-noise, an extended dynamic range, and very high electromagnetic immunity.

The modular concept permits the capsule to be detached and used at a distance from the output stage of up to 100 m (330 ft), connected via a special cable. For usual applications, the LC 4 cable is available with a length of 5 or 10 meters (ca. 16½ or 33 ft.). Alternatively, capsule extensions of various lengths, swivel capsule joints, and swivel stand mounts, etc. may be used for a flexible microphone setup.

The analog, transformerless output stage KM A operates with P48 phantom power. A switchable -10 dB preattenuation allows for sound pressure levels of up to 152 dB (depending on capsule type) without distortion artifacts.
