MAXIMUM FLEXIBILITY IN THE ANALOG AND DIGITAL DOMAINS
The combination of the capsule KK 145 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 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 (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 and digital output stages have identical dimensions (diameter: 22 mm, length: 93 mm). All accessory parts may thus be combined with both output stages.
A lot of examples for using the accessory portfolio can be found here.
THE OUTPUT STAGES
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.
Two popular combinations are available as complete sets with capsule, output stage and swivel mount: KM 183 A nx and KM 184 A nx. Any other components are offered separately.
COMPABILITY WITH THE NEUMANN KM 100 SYSTEM
On special request, a mechanical adapter (AR 100 KA) can be supplied for use of older KM 100 capsules (AK series) with the KM A and KM D output stages.
CAPSULE KK 145
The KK 145 is a pressure gradient transducer with cardioid characteristic just like the KK 184. However, it has an acoustic bass roll-off in the free field and therefore suppresses LF interference (wind, structure-borne noise). Since proximity effect is a natural feature of pressure gradient microphones, the KK 145 is optimized for a flat frequency response at a recording distance of approximately 15 cm („speech cardioid“).
The digital Neumann microphone technology (Solution-D) will no longer be part of the Neumann product portfolio from 2021. Last order date for dealers will be 31 July 2020. After that, the products will be available as long as stock lasts. Service for all Solution-D hardware products is guaranteed until 31 Dec 2030.
