The design of the microphone
is a registered design of
the Georg Neumann GmbH
in certain countries.
he TLM49 is a large-diaphragm studio microphone
with a cardioid directional characteristic and a warm sound
which is especially optimized for vocal performance. It is
supplied as a set, with an elastic suspension.
The design is inspired by that of the legendary M49 and
M 50 microphones of the 1950s. Naturally the TLM 49 has
the typical Neumann fine matte nickel finish. The “sound
design” is also oriented toward that of the M49 and the
U 47.
By combining its retro look with proven Neumann trans-
formerless circuit technology, this microphone ensures low
self-noise and the use of high gain levels.
Applications
During the development phase, the sound was
adjusted in extensive practical tests, so as to
make the TLM 49 ideal particularly for vocal and
speech recording. However, in addition, it is also
suitable for instrumental applications in profession-
al production studios and demanding home record-
ings.
Polar patterns
The large-diaphragm capsule of the TLM 49 provides a car-
dioid directional characteristic with a tendency toward su-
percardioid, due to the special capsule construction. Follow-
ing the example of the M49, high frequencies are more di-
rectional. The capsule diameter is 34 mm.
The front of the microphone is indicated by the red Neu-
mann logo on the microphone body. The capsule is oriented
so that the microphone is addressed from the front.
Acoustic features
The TLM49 uses the famous K 47 capsule, which was also
used in the M49 and the U 47. The capsule has a linear
frequency response up to the upper mid-range. Above 2 kHz
there is a gentle presence boost up to 3 dB.
The capsule is enclosed by a large microphone headgrille,
which is acoustically very open and is hence neutral with re-
gard to the sound.
Electrical features
The letters TLM stand for “transformerless microphone”.
With TLM technology the usual output transformer is re-
placed by an electronic circuit.
As with traditional transformers, it ensures good common
mode rejection, and prevents RF interference that may in-
fluence the balanced audio signal.
