The combination of the capsule KK 184 with the output stage KM A is only one of the numerous options within the Neumann KM A/D small diaphragm microphone system. The Neumann system KM A/D is a modular microphone system for even the most demanding applications. Eight different small diaphragm capsules (KK 120 up to KK 185) may be combined with either an analog output stage (KM A) or a digital AES 42 output stage (KM D). All components are available in nickel or Nextel black (nx). A comprehensive range of accessories ensures adaptability to the most diverse fields of application. The KK 184 is a pressure gradient transducer with cardioid characteristic. The frequency curves are very even and parallel to 0° sound incidence. In typical usage, there is no coloration of sound over a wide pickup angle.

KM A/KM D output Stage

The KM A analog output stage with P48 phantom power has a switch for pre-attenuation of 10 dB. The microphones can thus handle levels of up to 152 dB (depending on the capsule type). The KM D digital output stage converts the signal from the capsule directly into a digital signal. The result is an AES/EBU signal with 24 bits and a large dynamic range. The integrated digital signal processor (DSP) permits remote control of the microphones, including the digital gain, pre-attenuation (6 dB, 12 dB or 18 dB) and low-cut filter (0 Hz, 40 Hz, 80 Hz or 160 Hz). An integrated peak limiter and compressor/limiter with additional de-esser function prevents any overloading of the audio signal.

The dimensions (diameter 22 mm, length 93 mm) of the analog and digital output stages are identical. As a result, all accessories can be used in combination with both output stages. Upon request, a mechanical adapter can be supplied to adapt microphone capsules of the KM 100 system (AK series) to the KM A and KM D output stages.

The modular solution permits the microphone capsule to be separated from the output stage by a distance of up to 100 m. The LC 4 microphone cable with a length of 5 or 10 meters is available as a standard solution. Alternatively, capsule extensions of different lengths, swivel joints and stand mounts, etc., can be used for a flexible system setup.

The capsule heads KK 183, KK 184 or KK 185, together with the appropriate output stage, are also available as a set, in which case they are referred to as KM 183 A, KM 183 D, etc.
