Description

The SKM 183 is stereo set of two KM 183 Omnidirectional Microphones, two SG 21 BK Stand Mounts and two WNS 100 Windscreens in a woodbox

Because of KM 183's optimized mechanical construction and conscious omission of modularity, which is unnecessary in many cases, the "KM 183" is predestined for economy-minded production and home recording studios.

The KM 183 omnidirectional is based on the tremendously successful KM 184 cardioid microphone, which has become a standard within the global studio community in just a very short time. The KM 183 microphone is available with either Matte Black or Nickel finish with transformerless circuitry.

Applications

Their slender shapes and the transmission characteristics described below make the "Series 180" especially suitable for a very wide range of tasks in the radio and television sector.

  • Ideal as AB stereo pair because of the flat frequency response in the diffuse sound field
  • As a main mic, especially for capturing room acoustics
  • For stereo recordings with a baffle plate
  • As a spot mic for piano, wind instruments, organ, choir

Acoustic Features

The KM 183 microphone is the successors of the well proven KM 83, which has been used since the seventies worldwide with great success. The KM 183 is a pressure transducer with a boost of approximately 7 dB at 10 kHz in the free field. In the diffuse sound field it has a flat frequency response.

Electrical Features

The KM 183 microphone has the same transformerless circuitry as is used in the KM 100 system, resulting in excellent technical specifications: The microphone operates without any problems, even if the input of following equipment happens to be unbalanced, for example as in some DAT recorders. The output of the KM 183, as in all Neumann microphones, is balanced and phantom (48V) powered.

Economy

The KM 183 is a good choice for all users who look for a high-quality miniature microphone, but do not need the complex, modular KM 100 system, which continues to be part of the Neumann product range.

The mechanical construction was simplified, for example, capsule and output stage cannot be separated from each other. For this reason the KM 183 is an economical alternative without giving up the electroacoustic features the users expect from Neumann microphones.

SG 21 Bk Stand Mount

Swivel mount with a plastic clamp for miniature microphones. It has a 5/8"-27 female thread, plus a thread adapter to connect to 1/2"- and 3/8" stands.

WNS 100 Windscreen

Close range sounds, wind, and fast movements of the microphone boom, all may cause interfering noises. To avoid these unwanted sounds, windscreen accessories are available. Typically, they are made out of open-cell polyurethane foam. These windscreens do not cause interfering resonances and do not influence the directional pattern. Only in the upper frequency range is the output level slightly attenuated. The wind noise attenuation was measured without electrical filtering in a turbulent air stream traveling at 20 km/h, generated by a noiseless wind machine.

  • Wind noise attenuation 18 dB
  • Attenuation at 15 kHz 2 dB. Ø 45 mm
