U 47 – The Legend

For approximately 20 years Neumann had manufactured

and sold throughout the world the condenser microphone

CMV 3, also known as the “Neumann-Bottle”. Building on

its success it became time to start something new.

The cardioid M 7 microphone capsule had been manufac-

tured for many years with two equal diaphragms fixed on

both sides of a perforated center electrode which is also

provided with a number

of cavities on both sides

.One of the membranes is

gold coated and thus elec-

trically active. This mem-

brane is directed towards

the sound source.

The sound coming from

the front causes move-

ment of the front mem-

brane and reaches the in-

ner side of the rear mem-

brane through the

perforations in the electrode. The sound also reaches the

outside of the rear membrane. The acoustic properties

of the center electrode cause the forces acting on the rear

membrane to be equal in size, but opposite in direction.

Therefor, the rear membrane does not move and does not

produce any electrical signal. For sound arriving from be-

hind, the rear membrane moves and the front membrane

does not. As a consequence, the microphone does not re-

spond to rear sound, and

the directional character-

istic is cardioid.

Both capsule halves thus

act as a cardioid capsule

and led Neumann to

make the rear membrane

electrically active by coat-

ing it with gold too.

When connecting both

cardioid halves in parallel,

the capsule produces an

omni directional pattern.

If only one membrane is

connected, the microphone works as described above as a

cardioid.

The prerequisites for an easily switchable microphone with

two directional characteristics were now fulfilled. A steel

vacuum tube VF 14 M was selected for the impedance

converter/amplifier, a pentode being operated as triode.

The microphone was fed with one supply voltage only, from

which the filament voltage was derived by means of a wire

wound resistor inside the amplifier housing. Consequently

which may be partially responsible for its legendary lon-

gevity by providing a low humidity environment for the

capsule. This was certainly not responsible for the “full,

rich and warm sound” the U 47 is famous for, a sound qual-

ity still highly regarded in our days. Many recording studi-

os are proud to claim ownership of a working U 47.

During the 1950’s Neumann microphones also were sold

through Telefunken, and carried the Telefunken logo. Thus

the U 47 was also known as the “Telly”. It was reported

about “The Voice”, Frank Sinatra, that he wouldn’t sing

without his “Telly”, the Neumann U 47. From the Bar-

clay Studios in Paris, which were technically supervised

by Gerhard Lehner, we learned of people admiringly claim-

ing: That’s a microphone to drive nails into walls with.

Whether this is understood literally or figuratively, it is a

compliment for the U 47 either way!

the microphone itself produced a fair amount of heat,
