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.
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.
The capsule is enclosed by a large microphone headgrille, which is acoustically very open and is hence neutral with regard to the sound.
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).
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.
