The new, considerably smaller microphone capsules and an extensive program of accessories permit excellent adaptation of the microphone system to a wide range of applications.
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.

TRUE NEUMANN SOUND: The legendary Neumann sound in the digital realm.
Pure Neumann capsule sound.
TRUE TO THE ORIGINAL: The satisfaction of recording the uncolored original,
with no "bottlenecks" between the capsule and the recording system.
TRUE CONVERSION: The guarantee of having one of the best
A/D converters available.
TRUE HANDLING SAFETY: Anti-clipping processing ensures handling safety,
and reduces stress.
TRUE TIME SAVINGS: Reduced time requirements and personnel costs,
particularly due to faster post production processing.
TRUE ECONOMY: Lower investment costs, since separate A/D converters and preamps are no longer needed. This also means space and weight savings (e.g. in the OB van).
