Caution: Very loud noise can damage loud-
speakers or your hearing!
Minimize the volume of connected playback and
recording equipment before connecting the mi-
crophone.
Using a suitable cable, connect the microphone
to the microphone input of the audio equipment
to be used for subsequent processing, or to the
designated P48 power supply equipment. Infor-
mation concerning connector assignment can be
found in the “Technical data” section.
Cable lengths of up to approximately 300 m be-
tween the microphone and the subsequent am-
plifier input have no effect on the frequency re-
sponse of the microphone.
When connecting the cables, ensure that the con-
nectors are locked correctly. Run the cables in
such a way that there is no risk of tripping over
them.
Address the microphone from the front, the side
on which the Neumann logo is located.
Gradually increase the volume of the connected
equipment
Set the gain of the connected equipment so that
no distortion occurs at the highest sound pres-
sure level.
Selecting the directional characteristic
There are three selectable directional character-
istics, which allow the microphone to be adapted
to individual recording situations: omnidirection-
al, cardioid and figure-8. The slide switch for the
directional characteristics is located on the front
of the microphone, below the headgrille.
When the directional characteristic is changed,
an increased noise level may occur for a period of
approximately 30 seconds. This does not indicate
a malfunction, but arises due to the electrical
recharging of the microphone capsule to the ap-
propriate bias. As a precaution, reduce the signal
level of connected equipment when changing the
directional characteristic.
Setting the pre-attenuation
Pre-attenuation is activated by means of a switch
on the back of the microphone. It increases the
maximum signal level by 10 dB, in order to avoid
overloading when transmitting signals at ex-
tremely high sound pressure levels.
Setting the high-pass filter
The high-pass filter is activated by means of a
switch on the back of the microphone. It can be
used to suppress low-frequency interference (e.g.
caused by impact sound or wind noise) or to com-
pensate for the proximity effect.
Suppressing noise interference
The frequency response of the TLM 67 extends
below 20 Hz. The microphone is of course cor-
respondingly sensitive to low-frequency interfer-
ence such as structure-borne noise and wind or
pop noise. Depending upon the situation, the use
of an elastic suspension, a windscreen and/or a
popscreen is therefore recommended.
Sound test
Simply speak into the microphone. Do not blow
into the microphone or subject it to pop noise,
since this can easily result in hazardous sound
pressure levels.
6. Shutdown and Storage
Before switching off the microphone or discon-
necting the cables, reduce the volume of con-
nected equipment.
Only then should the phantom power be switched
off.
Disconnect the cables.
When disconnecting a cable, always pull only on
the connector and not on the cable itself.
Microphones which are not in use should not be
allowed to remain on the stand gathering dust. A
microphone which is unused for a prolonged pe-
riod should be stored under normal atmospheric
conditions, and should be protected from dust.
For this purpose, use a lint-free, air-permeable
dust cover or the original packaging of the micro-
phone.
