The
Neumann KM A / KM D Miniature Microphone System
The modular KM A / KM D miniature microphone system is a further
development of the successful KM 100 series. The newly developed
passive capsule design is available with 8 different directional
characteristics, and can be combined modularly as desired with an
analog (KM A) or digital (KM D) output stage in accordance with the
AES 42 standard. 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.
Through the use of the most up-to-date electronic components the
system offers many electroacoustic and operational advantages, such
as lower self-noise, a wider dynamic range and very high immunity
to electromagnetic interference. The acoustics of the capsules were
taken from the proven KM 100 system.

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. |
� Miniature
microphones with 8 exchangeable capsules, compatible with the analog miniature
microphone system KM A
� Set includes windshield and clamp
� Extensive accessories
� 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). |
