Neumann TLM67

NEUMANN TLM67 NIMicrophone Multipattern Wide Diaphragm

In the world of studio microphones, the numbers “47”, “67” and “87” have implications that inspire enthusiasm among professionals in the field. 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 design of the new circuit closely reproduces the characteristic sound of the classic U 67, without the use of tubes. Similar Neumann circuit technology has already been proven very successful in the TLM 49.
The TLM 67 is extremely versatile. Its three switchable directivity patterns (omnidirectional, cardioid and figure-8), selectable 10 dB pre-attenuation and high-pass filter allow detailed adjustments, depending on the specific 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 elegant pearl gray of the microphone body combined with the classic Neumann nickel gives the microphone a touch of distinctive uniqueness.
The legendary and often imitated Neumann U 67 design was the first to be developed by Neumann employees in collaboration with the famous German designer, Wilhelm Braun-Feldweg. The TLM 67 design represents a contemporary development of the U 67, transferring its positive impact into the present era. The enhanced exterior design therefore unites past and future microphone design trends.
On the occasion of its 80th anniversary, the Neumann company honors its founder, Georg Neumann, with a three-dimensional metal emblem on the front of the TLM 67. The particular appeal of Neumann is conveyed in every detail of the microphone.

APPLICATIONS

Due to its wide control characteristics, 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 word, in orchestral recordings the TLM 67 can be used as a main microphone and as a proximity microphone for individual instruments.

ACOUSTIC CHARACTERISTICS

The microphone is directed from the side on which the Neumann logo is located.
A large metal mesh grille encloses the elastically mounted dual-diaphragm capsule. Omnidirectional, cardioid or figure-8 directivity patterns can be selected by a switch below the grille. The selected setting is indicated by a symbol displayed in a window above the switch.

ELECTRICAL FEATURES

The letters “TLM” stand for “transformerless microphone”. In the TLM 67, an electronic circuit is used in place of a conventional output transformer. Like a transformer, the circuit ensures good common-mode rejection, effectively suppressing interfering signals affecting the balanced modulation line. The microphone can operate at sound pressure levels 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 rear 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 downstream devices due to very high sound pressure levels. The use of the switch does not increase the dynamic range of the microphone, but moves it by 10 dB, for higher sound pressure levels. The other switch on the rear of the microphone can be used to change the cutoff frequency of the built-in high-pass filter, to suppress the effects of impact sound and wind noise, or to compensate for proximity effect.

OPERATIONAL RELIABILITY

The elastic mounting of the capsule provides protection from structure-borne noise transmission. If required, the EA 87 elastic suspension and WS 87 windshield are available as accessories, for further structure-borne noise and wind noise suppression. PS 15 or PS 20 pop shields can be used if the microphone is located in close proximity.
