he TLM 49 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 M 49 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 M 49 and the
U 47.

By combining its retro look with proven Neumann trans­formerless 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 design of the microphone
is a registered design of
the Georg Neumann GmbH
in certain countries.

The large-diaphragm capsule of the TLM 49 provides a car-

dioid directional characteristic with a tendency toward su­percardioid, due to the special capsule construction. Follow­ing the example of the M 49, high frequencies are more di­rectional. The capsule diameter is 34 mm.

The front of the microphone is indicated by the red Neu­mann logo on the microphone body. The capsule is oriented
so that the microphone is addressed from the front.

Acoustic features

The TLM 49 uses the famous K 47 capsule, which was also
used in the M 49 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 re­gard to the sound.

Electrical features

The letters TLM stand for “transformerless microphone”.
With TLM technology the usual output transformer is re­placed by an electronic circuit.

As with traditional transformers, it ensures good common
mode rejection, and prevents RF interference that may in­fluence the balanced audio signal.

Noise signals which affect the balanced modulation line are
therefore effectively suppressed. The microphone can oper­ate at sound pressure levels of up to 140 dB, and provides a
dynamic range of 117 dB (A-weighted).

Operational reliability

The entire interior structure is mounted elastically, to pre­vent the transmission of structure-borne noise. In addition,
the capsule is mounted with a rubber shock mount.

Due to the wide frequency response, the TLM 49 can also
transmit extremely low-frequency signals without coloration.
Of course this means that the microphone is also sensitive
to noise signals such as vibration noise and wind noise in this
frequency range. The TLM 49 is therefore supplied with the
elastic suspension EA 3, which effectively protects the mi­crophone from structure-borne noise. If the microphone is
addressed at extremely close range, pop screen PS 15 or
PS 20 a can be used in front of the microphone to provide
protection against plosive sounds.

These are just some of the most common applications. We
recommend additional experimentation to gain maximum use
from this microphone.
