Neumann KM 185 Cardioid Microphone
The slender shape and transmission characteristics make the Neumann KM 185 especially suitable for a very wide range of tasks in the radio and television sector.
The pressure gradient transducer Neumann KM 185 features a very smooth frequency response 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 KM 185 with its hypercardioid characteristic features attenuation of sound incidence from the side or rear of about 10 dB, with minimum sensitivity at an angle of 120 degrees.The KM 185 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/CF recorders. The output of the KM 185, as in all Neumann microphones, is balanced and phantom (48V) powered.
The KM 185 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 185 is an economical alternative without giving up the electroacoustic features the users expect from Neumann microphones.
