Neumann TLM67 SetZ Large Diaphragm Microphone

A contemporary development of the legendary U67. K67 capsule, new circuit design, which closely reproduces the U67 sound characteristics, three directional pattern, pre-attenuation and high-pass filter. Novel Neumann dual-color design.

In the world of studio microphones, the numbers "47", "67" and "87" have associations that inspire enthusiasm among professionals in the field. It is of course no coincidence that the name of the new TLM67* contains the number "67". In many respects, the TLM67 is based on the "workhorse" of the 1960s, the legendary U67. Like the U67, the TLM67 incorporates the K67 capsule. In addition, the special new circuit design closely reproduces the sound characteristics of the classic U67, without the use of tubes. Similar Neumann circuit technology has already proved very successful in the TLM49.

The TLM67 is extremely versatile. Its three switchable directional characteristics (omnidirectional, cardioid and figure-8), selectable 10 dB pre-attenuation and high-pass filter permit detailed adjustments to be made, depending upon the specific recording situation.

Exterior design
The TLM67 is a large-diaphragm condenser microphone in the classic Neumann style, with a unique dual-color design. The stylish pearl-gray of the microphone body combined with the classic Neumann nickel lends the microphone a touch of distinctive individuality.

The legendary, frequently imitated design of the Neumann U67 was the first to be developed by Neumann employees in collaboration with the famous German designer, Wilhelm Braun-Feldweg. The design of the TLM67 represents a contemporary development of that of the U67, transferring its positive impact to the present era. The enhanced exterior design thus links past and future microphone design trends.

On the occasion of its 80th anniversary, the Neumann company is honoring its founder, Georg Neumann, with a three-dimensional metal emblem on the front of the TLM67. The distinctive Neumann attraction is conveyed in every detail of the microphone.

Applications
Due to its extensive control features, the TLM67 is suitable for a wide range of applications. In addition to its primary role as a vocal microphone for all types of music and spoken voice, in orchestral recordings the TLM67 can be used as a main microphone and as a spot microphone for individual instruments.

Acoustic features
The microphone is addressed from the side on which the Neumann logo is located.

A large wire mesh grille encloses the elastically mounted double diaphragm capsule. The directional characteristics omnidirectional, cardioid or figure-8 can be selected via a switch below the grille. The selected setting is indicated by a symbol shown in a window above the switch.

Electrical features
The letters "TLM" stand for "transformerless microphone". In the TLM67, an electronic circuit is used rather than a conventional output transformer. Like a transformer, the circuit ensures good common mode rejection, effectively suppressing interference signals that affect the balanced modulation line. The microphone can operate at sound pressure levels of up to 105 dB without distortion, and has a dynamic range of 94 dB (A-weighted), without the use of the pre-attenuation switch.

Filter and pre-attenuation
The pre-attenuation switch on the back of the microphone can be used to reduce transmission levels by approx. 10 dB. It should be used only when there is a risk of overloading following devices due to very high sound pressure levels. Use of the switch does not increase the dynamic range of the microphone, but rather shifts it by 10 dB, to higher sound pressure levels. The other switch on the back of the microphone can be used to change the cutoff frequency of the built-in high-pass filter, so as to suppress the effects of impact sound and wind noise, or to compensate for the proximity effect.

Operational reliability
Elastic mounting of the capsule supplies protection from the transmission of structure-borne noise. If required, the EA87 elastic suspension and WS 87 windscreen are available as accessories, for further suppression of structure-borne and wind noise. The PS15 or PS20 a popscreen can be used if the microphone is to be addressed at close range.

*The design of the microphone is a registered design of the Georg Neumann GmbH in certain countries.
