Miniature Microphones
Economy
The “Series 180” is a good choice for all users
who look for a high-quality miniature micro-
phone, but do not need the complex, modu-
lar 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.
The pressure gradient transducers KM 184 and
KM 185 feature very smooth frequency re-
sponses 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.
The KM 185 with its hypercardioid characte-
ristic features attenuation of sound incidence
from the side or rear of about 10 dB, with mi-
nimum sensitivity at an angle of 120°.
Electrical features
The “Series 180” microphones have the same
transformerless circuitry as is used in the KM 100
system, resulting in excellent technical specifi-
cations: Compared to the KM 84 the dynamic
range of the KM 184 increased by 21 dB mainly
through the reduction of self-noise level to only
25 dB (CCIR) and an increased sound pressure
handling capability of up to 138 dB.
The microphones operate without any pro-
blems, 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 Neu-
mann microphones, is balanced and phantom
(48V) powered.
