In the world of studio microphones, the numbers “47”, “67” and “87” have associations that inspire enthusiasm among professionals in the fi eld. It is of course no coincidence that the name of the new TLM 67 contains the number “67”. In many respects, the TLM 67 is based on the “workhorse” of the 1960s, the legendary U 67. Like the U 67, the TLM 67 incorporates the K 67 capsule. In addition, the special new circuit design closely reproduces the sound characteristics of the classic U 67, without the use of tubes. Similar Neu­mann circuit technology has already proved very successful in the TLM 49.
The TLM 67 is extremely versatile. Its three switchable directional characteristics (omnidirectional, cardioid and fi gure-8), selectable 10 dB pre-attenuation and high-pass fi lter permit detailed adjustments to be made, depending upon the specifi c recording situation.
Exterior design
The TLM 67 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 U 67 was the fi rst to be developed by Neumann employees in collaboration with the famous German designer, Wilhelm Braun-Feldweg. The design of the TLM 67 represents a con­temporary development of that of the U 67, 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 three­dimensional metal emblem on the front of the TLM 67. The distinctive Neumann attraction is conveyed in every detail of the microphone.
The design of the microphone is a registered design of the Georg Neumann GmbH in certain countries.
Applications
Due to its extensive control features, the TLM 67 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 TLM 67 can be used as a main microphone and as a spot microphone for individual instruments.
Acoustic features
The TLM 67 is addressed from the side. The front is indica­ted by the Neumann logo.
A large wire mesh grille encloses the elastically mounted double diaphragm capsule. The directional characteristics omnidirectional, cardioid or fi gure-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 TLM 67, an electronic circuit is used rather than a conventional output transformer. Like a transformer, the circuit ensures good common mode rejection, eff ectively suppressing interference signals that aff ect 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 fi lter, so as to suppress the eff ects of impact sound and wind noise, or to compensate for the proximity eff ect.

Operational reliability
Elastic mounting of the capsule supplies protection from the transmission of structure-borne noise. If required, the EA 87 elastic suspension and WS 87 windscreen are availa­ble as accessories, for further suppression of structure-bor­ne and wind noise. The PS 15 or PS 20 a popscreen can be used if the microphone is to be addressed at close range.
