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 up to 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 diverse 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, connected via a special cable. For usual applications, the LC 4 cable is available with a length of 5 or 10 meters. 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.
