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.
Come in pair in a jewelry box.
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.
Although the KM 184 has the same capsule as the KM 84, the microphone differs slightly on the 0° frequency response: The KM 184 has a gentle rise at about 9 kHz, a characteristic that was introduced very successfully with the KM 140. The result is a tonal balance that is fresher and livelier when compared to the KM 84 with its flat frequency response in that band.
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.
