Neumann TLM
49 Studio Microphone |
|
Product Code: TLM49
|
The 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 professional production studios and demanding home recordings.
Polar pattern
The large-diaphragm capsule of the TLM 49 provides a cardioid 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 129 dB without distortion, and provides a dynamic range of 117 dB
(A-weighted).
Operational safety
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. |
