Product Overview
The KM 183 is a state-of-the-art small diaphragm condenser microphone with a frequency-independent omnidirectional polar pattern. Its very natural, transparent sound with very low self-noise and high SPL capability have made the KM 183 a worldwide studio standard for many applications ranging from classical piano to heavy metal drums.
Includes
- KM 183 Black Miniature Omnidirectional Condenser Microphone
- Stand mount
- Windscreen
Features
- Acoustic:
- The KM183, a successor to the KM83, is a pressure transducer with a boost of approximately 7dB at 10kHz in the free field. In the diffuse sound field it has a flat frequency response.
- Electrical:
- The "Series 180" microphones have the same transformerless circuitry as is used in the KM100 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.
