Neumann KM 183 A NX Modular Omnidirectional Small Diaphragm Condenser Microphone, Nextel

The combination of the capsule KK 183 with the output stage KM A is only one of the numerous options within the Neumann KM A/D small diaphragm microphone system.

The Neumann system KM A/D is a modular microphone system for even the most demanding applications. Eight different small diaphragm capsules (KK 120 KK 185) may be combined with either an analog output stage (KM A) or a digital AES 42 output stage (KM D). All components are available in nickel or Nextel black (nx). A comprehensive range of accessories ensures adaptability to the most naverse fields of application.

Compared to its predecessor, the Series KM 100, the new system KM A/D 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. 16 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 and digital output stages have identical dimensions (diameter: 22 mm, length: 93 mm). All accessory parts may thus be combined with both output stages.
