Neumann
KM 84 |
The
Neumann KM84 microphone is a small capsule cardioid condenser
and was the first mic made with 48v phantom power technology.
The KM is German for Kleine Microphone (small microphone) and
all the electronics were deliberately made quite small so that
the mic could be made with a diameter of only 21 mm and a length
of 110 mm. It has a 10 dB attenuation switch allowing the microphone
to be used up close with loud instruments and by placing the pad
at the gate of the field-effect transistor (FET), this "pre-attenuation"
prevents the hot capsule signal from overloading the front end
of the amplifier enabling the mic to handle up to 130db without
distortion. The Neumann KM84 has become a real favourite for classical
music recording because of its smooth faithful reproduction but
its also known as a favourite mic for drum overheads. The mic
is very sensitive to low-frequency mechanical vibrations so you
need to be careful where you stand it and really it needs a good
pop shield as its also pretty susceptible to wind noise but these
are small considerations balanced against the quality of the mic.
The more recent variant, the KM 184 is essentially the same microphone
and apart from obvious cosmetic differences, it has the same capsule
as the KM 84 but with a lift around 9 kHz, to give it a brighter
top end.

Recording |
Possibly my favourite mic not just because it gives such a faithful
reproduction but it really retains its integrity through the
recording and mixing session. 10 hours down the line and 20
guitars overdubs later it's still there. It has a quality that
retains its detail through the session whether as drum O/Hs
or on an acoustic guitar. What happens when by the time you’ve
recorded a couple of distorted guitar tracks you’ve eaten
up all the high frequency so you end up pilling on a load more
top end in the mix. It's great on acoustic guitar as it brings
out all the detail and clarity without any of the boominess
at the bottom and it doesn’t flatter the top end so you
can add eq if you want to. However it's its mid range integrity
that I really like and I have to say it’s something that
the Rode NT5s don’t have. Don’t get me wrong they
are great little mics for the money and put them up over a kit
or in front of an acoustic and they sound fine on their own
but once you start eating up the frequency range with other
instruments they don’t hold good in the way that the kM84
does. Having a pair of 84s when I’ve needed to record
a singer and his guitar I have used the 84s and got a pretty
good vocal sound, not particularly close up but it worked out
very well. It's the best drum overhead mic we have at Fairview
but when I started the o/h mics were the Neumann U87s but I
don’t think that U87s are focused enough for that particular
job and I only use them now if a drummer walks in and he’s
got like 10 cymbals and you just have to put a pair up over
the top to get a stereo picture. But if someone’s got
a small kit with a pair of really nice crash cymbals then I
haven’t found anything else as good as the 84s. Just put
them a couple of foot above and you get lovely detail without
too much stuff from the rest of the kit. Simply a great microphone.
