Neumann History

Back to the Tubes

The assertion above that the U 67 was Neumann’s
last tube microphone is not entirely correct.

Down  to  the  present  day,  the  development  of
semiconductor circuitry has resulted in tremen-
dous improvements in specifications. There has
also  been  amazing  improvement  in  the  relia-
bility  of  all  components.  Quality  and  utmost
technical  complexity  have  become  common-
place. Equipment available only to profession-
als  a  few  years  ago  is  now  available  for  rela-
tively little money.

Nevertheless, one “old-fashioned” component
has, despite a brief slumber, never disappeared,
especially in the studio sector: tubes. First they
became popular in power amplifiers, where they
could bring their pleasant sounding qualities to
bear, then the clamour for a microphone reviv-
al became increasingly loud.

In  1995,  Neumann  responded  with  its
M 149 Tube. The “49” in the name is no acci-
dent,  since  this  large  dia-
phragm microphone with nine
switchable directional charac-
teristics  falls  back  on  distin-
guished  ancestors  through  its
use of the K 47/49 capsule and
its design. The circuitry is mod-
ern, however, despite the tube
impedance converter which de-
termines the sound. The output
stage  contains  a  transformer-
less, solid-state amplifier that
can  handle  high  modulation
levels for driving even long mi-
crophone  cables.  This  was  al-
ways a problem with this micro-
phone’s ancestors, since cable
material and length were always unforeseeable
factors affecting the resulting sound.

Highlights  of  the
End of the Millenium

At  the  end  of  1998,  exactly  one  century  after
the  birth  of  Georg  Neumann,  the  M 149 Tube
inspired  the  new  M 147 Tube.  Limited  to  the
most popular directional characteristic, the car-
dioid  characteristic,  the  M 147 Tube  features
the same capsule and circuit technology as the
award-winning M 149 Tube.

Another highlight in the history of the compa-
ny occurred shortly before the end of the mille-
nium: In February, 1999, Neumann was award-
ed the Technical Grammy in Los Angeles for its

contributions  of  outstanding  technical  signifi-
cance to the recording field and the audio world.
In addition a large number of Neumann products
received the coveted TEC Award from the Amer-
ican MIX magazine: the TLM 50, the M 149 Tube,
the TLM 103, the M 147 Tube, the KMS 105, the
M 150 Tube and finally the TLM 127, which ap-
peared in the year 2003.

Neumann on Stage

Although a few artists had al-
ready favored the use of Neu-
mann microphones such as the
KMS 85  and  KMS 140  on  the
stage, it was only with the de-
velopment  of  the  KMS 105  in
1999  that  Neumann  first  ex-
panded  into  the  vast  field  of
live  stage  applications  on  a
larger  scale.  Not  long  after-
ward, this microphone became
established as an internation-
ally recognized standard in the
area of live vocal microphones.

The demand for a wireless ver-
sion became ever more press-
ing. The natural use of the syn-
ergy effects of the parent com-
pany  Sennheiser,  which  for
years  has  been  known  as  the
best source of wireless technol-
ogy,  permitted  the  develop-
ment of versions of the capsule
head  which  can  be  used  with
the Sennheiser SKM 5000 wire-
less  system.  Neumann  micro-
phones can now be seen regu-
larly on television at large con-
certs and television shows.
