Product Overview
Because of its optimized mechanical construction and conscious omission of modularity, which is unnecessary in many cases, the "Series 180" KM 183 is predestined for economy-minded production and home recording studios.
The KM 183 omnidirectional microphone is based on the successful KM 184 cardioid microphone, which has become a standard within the global studio community.
Applications
The KM 183's slender shape and the transmission characteristics described below make it especially suitable for a wide range of tasks in the radio and television sector.
Includes:
- SG 21 BK stand mount
- WNS 100 windscreen
Acoustic Features
- The KM 183, a successor to the KM 83, 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 "Series 180" microphones have the same transformerless circuitry as is used in the KM 100 system, resulting in excellent technical specifications:
- The microphones operate 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 "Series 180", as in all Neumann microphones, is balanced and phantom (48V) powered.
- Economy
- The "Series 180" 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 "Series 180" is an economical alternative without giving up the electroacoustic features the users expect from Neumann microphones.
