The slender shape and transmission characteristics described
below make the KM184 especially suitable for a very wide range of
tasks in the radio and television sector. It is extremely quiet
(16dB A-weighted self-noise), making it excellent for capturing the
subtle nuances of acoustic guitar and orchestral perf ormances .
The KM 184 microphone is the successor of the well proven KM 84,
which has been used since the seventies worldwide with great
success.
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. 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 microphone
operates without any problems, even if the input of following
equipment happens to be unbalanced, for example as in some DAT/CF
recorders. The output of the KM 184, as in all Neumann microphones,
is balanced and phantom (48V) powered.
The KM 184 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 this model,
for example, capsule and output stage cannot be separated from each
other. For this reason the KM 184 is an economical alternative
without giving up the electroacoustic features the users expect
from Neumann microphones.
