ables Neumann users worldwide to share their
experiences. Through its integrated archive func-
tion, the forum has developed into an extensive
knowledge pool.
2. Safety instructions
The microphone has the intended purpose of con-
verting acoustic signals into electrical signals.
Connect the microphone only to microphone in-
puts and devices which supply 48 V of phantom
power in accordance with IEC 61938.
Repairs and servicing are to be carried out only
by experienced, authorized service personnel.
Unauthorized opening or modification of the
equipment shall void the warranty.
Use the equipment only under the conditions
specified in the “Technical data” section. Allow
the equipment to adjust to the ambient tempera-
ture before switching it on. Do not operate the
equipment if it has been damaged during trans-
port.
Always run cables in such a way that there is no
risk of tripping over them.
Unless required for operation, ensure that liquids
and electrically conductive objects are kept at a
safe distance from the equipment and its connec-
tions.

Do not use solvents or aggressive cleansers for
cleaning purposes.
Dispose of the equipment in accordance with the
regulations applicable to the respective country.
3. Brief description
The TLM 170 is a condenser studio microphone
with transformerless (TLM) circuit technology.
The microphone features exceptionally clean
sound transmission which is free of coloration,
with extremely low self-noise and an extensive
dynamic range.
The TLM 170 R has the selectable directional char
-
acteristics omnidirectional, cardioid, wide-angle
cardioid, hypercardioid and figure-8. The direc-
tional characteristics can be selected remotely
with the optional N 248 power supply.
The largely linear diuse-field frequency response
permits even lateral sound to be transmitted
without coloration. This applies to all directional
characteristics.
A switchable high-pass filter increases the lower
cuto frequency from 30 Hz to 100 Hz.
The pre-attenuation switch reduces the micro-
phone sensitivity by 10 dB, thus allowing the pro-
cessing of very high sound pressure levels.
The TLM 170 R is elastically mounted on a tilting
bracket, for the suppression of structure-borne
sound.

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 o the microphone or discon-
necting the cables, reduce the volume of con-
nected equipment.
Only then should the phantom power be switched
o.
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.
7. Troubleshooting
Problem
▶
Possible causes
▶
Solution
Microphone
not operating
The phantom power supply voltage is not
switched on at the mixing console or at the
power supply equipment.
Check the corresponding channel settings.
The power supply equipment is not con-
nected to the power supply line or there is
no battery.
Check the connection to the power supply
line or check the battery of the power supply
equipment.
No signal
transmission
The microphone is not connected to the
correct microphone amplifier input of the
subsequent equipment.
Check the signal path.
If necessary, activate the appropriate input
on the corresponding channel of the mixing
console.
