he “Series 180” consists of three com­pact miniature microphones with patterns
that satisfy the demands of all common stu­dio applications. Because of its optimized me­chanical construction and conscious omission
of modularity, which is unnecessary in many
cases, the “Series 180” is predestined for econ­omy-minded production and home recording
studios.

The KM 183 omnidirectional and KM 185
hypercardioid microphones are based on the
tremendously successful KM 184 cardioid
microphone, which has become a standard
within the global studio community in just a
very short time.

All “Series 180” microphones are available
with either matte black or nickel finish. They
come in a folding box with a windshield and
two stand mounts that permit connection to
the microphone body, or the XLR-connector.

Applications

Their slender shapes and the transmission char­acteristics described below make the “Series 180”
especially suitable for a very wide range of tasks
in the radio and television sector.

Features

• Three different miniature
microphones for all typical
studio applications

• Successor of the worldwide
successful KM 83/84

• Transformerless circuitry

Acoustic features

The KM 183 and KM 184 microphones are the
successors of the well proven KM 83 and
KM 84, which have been used since the sev­enties worldwide with great success. The
KM 185 rounds out the series with a hyper­cardioid microphone.

The KM 183 is a pressure transducer with a
boost of approximately 7 dB at 10 kHz in the
free field. In the diffuse sound field it has a
flat frequency response.

• Trouble-free operation also
with unbalanced equipment
(e.g., DAT recorders)

• Set includes windshield and
two different microphone
clamps

Series 180

The pressure gradient transducers KM 184 and
KM 185 feature very smooth frequency re­sponses 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 character­istic features attenuation of sound incidence
from the side or rear of about 10 dB, with min­imum 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
specifications: Compared to the KM 84 the dy­namic range of the KM 184 increased by 24 dB
mainly through the reduction of self-noise level
to only 22 dB (CCIR) and an increased sound
pressure handling capability of up to 138 dB.

The microphones operate without any prob­lems, 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 Neu­mann microphones, is balanced and phantom
(48V) powered.

Economy

The “Series 180” is a good choice for all users
who look for a high-quality miniature micro­phone, but do not need the complex, modular
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.
