Neumann TLM
67 Switchable Studio Microphone |
|
Product Code: TLM67
|
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 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 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 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 first 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 three-dimensional metal emblem on the front of
the TLM 67. The distinctive Neumann attraction is conveyed in every detail of
the microphone.
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 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 TLM 67, 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 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. |
