Neumann KM 183 Stereo Set
A matched pair of the famous Neumann KM 183 omnidirectional microphone offered in a wooden case with swivel clips and windscreens.
The "Series 180" consists of three compact miniature microphones with patterns that satisfy the demands of all common studio applications.
Because of its optimized mechanical construction and conscious omission of modularity, which is unnecessary in many cases, the "Series 180" is predestined for economy-minded production and home recording studios.
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.
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. The pressure gradient transducers KM 184 and KM 185 feature very smooth frequency responses not only for the 0° axis, but also for lateral (off-axis) sound incidence. In typical usage, there is no coloration of sound over a wide pickup angle.
The "Series 180" microphones have the same transformerless circuitry as is used in the KM 100 system, resulting in excellent technical specifications:
Compared to the KM 84 the dynamic range of the KM 184 increased by 24 dB mainly through the reduction of self-noise level to only 22 dB (CCIR) and an increased sound pressure handlingcapability of up to 138 dB.
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.
