The KM 120 Microphone from Neumann is
simply a microphone combination set consisting of the KM 100 phantom
power supply/output stage and the AK 20 bi-directional (figure 8)
microphone element. The swivel mount and windscreen are also included in
the set. Neumann's modular KM 100 series is designed to be versatile
with the ability to interchange microphone elements and accessories
based on individual applications.
The KM 100 is powered via 48
Volt phantom power and is designed for quick connection to all
compatible elements and accessories. The KM 100 uses transformer-less
circuitry resulting in high output capability and low self-noise. The
balanced XLR output is protected against radio frequency interference.
The entire microphone circuitry is built into the capsule on a single
hybrid module measuring 2cm in area. The result is a compact,
interchangeable output stage providing pristine output signal without
any coloration.
The AK 20 microphone element features a pressure
gradient, single diaphragm transducer with a figure 8 polar pattern. The
diaphragm diameter is just 16mm and all sound field components reach
the diaphragm directly. The end result is even frequency response and
output levels between 0 to 180 degrees in proximity. The figure 8 polar
pattern is effective in stereo MS recording (with an AK 40 or other
cardioid mic), ambiance capturing or lectures and conferences with 2
speakers at either ends of the microphone.
