The TLM 49* is a large-diaphragm studio microphone with cardioid directivity and warm sound specially optimised for vocal performances. It is supplied as a kit with an elastic suspension.

The design is inspired by the legendary M 49 and M 50 microphones from the 1950s. Naturally, the TLM 49 features Neumann's typical matt nickel finish. The "sound design" is also oriented towards that of the M 49 and U 47.

By combining its retro look with Neumann's proven transformerless circuit technology, this microphone guarantees low self-noise and the use of high gain levels.

Applications

During the development phase, the sound was adjusted through numerous practical tests, in order to make the TLM 49 particularly ideal for vocal and speech recording. However, it is also suitable for instrumental applications in professional production studios and demanding home recordings.

Directivity

The TLM 49's large-diaphragm capsule offers cardioid directivity with a tendency towards supercardioid, due to the special construction of the capsule. Following the example of the M 49, the 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 characteristics

The TLM 49 uses the famous K 47 capsule, which was also used in the M 49 and U 47. The capsule has a linear frequency response up to the upper midrange. Above 2 kHz, there is a slight presence boost of up to 3 dB.

The capsule is surrounded by a large microphone grille, which is acoustically very open and therefore neutral with respect to sound.

Electrical characteristics

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 could influence the balanced audio signal.

Spurious signals that affect the balanced modulation line are therefore effectively suppressed. The microphone can operate at sound pressure levels up to 129 dB without distortion, and offers a dynamic range of 117 dB (A-weighted).

Operational safety

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

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