Neumann KM 184 Stereo Set

Stereo Pair Series 180 Small-diaphragm Cardioid Condenser Microphones in Wooden Case - Nickel

Because of its optimized mechanical construction and conscious omission of modularity, which is unnecessary in many cases, the "Series 180" KM 184 is predestined for economy-minded production and home recording studios. The KM 184 cardioid microphone has become a standard within the global studio community.ApplicationsThe KM 184's slender shape and... morethe transmission characteristics described below make it especially suitable for a wide range of tasks in the radio and television sector.IncludesTwo KM 184 cardioid condenser microphonesTwo SG 21 BK stand mountsTwo WNS 100 windscreensAcoustic FeaturesThe KM 184 microphone is the successor of the KM 84, which has been used worldwide since the seventies.The pressure gradient transducer KM 184 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.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.This difference was achieved with just a slight change of the capsule's rear opening, and is not due to resonances.Electrical featuresThe "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.EconomyThe "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.SpecificationsAcoustical operating principle: Pressure gradient transducerDirectional pattern: cardioidFrequency range: 20 Hz - 20 kHzSensitivity at 1 kHz into 1 kohm: 15 mV/PaRated impedance: 50 ohmsRated load impedance: 1000 ohmsEquivalent noise level, CCIR*: 22 dBEquivalent noise level, A-weighted*: 13 dB-AS/N ratio, CCIR* (rel. 94 dB SPL): 72 dBS/N ratio, A-weighted* (rel. 94 dB SPL): 81 dBMaximum SPL for THD 0.5%**: 138 dBMaximum output voltage: 10
