Some Remarks on Microphone Maintenance
The Neumann online forum on our website
enables 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 and the accompanying power
supply equipment have the intended purpose
of converting acoustic signals into electrical
signals.
Connect the microphone only to power supply
equipment that has been approved by Neumann
for this purpose. Connect the output of the
power supply equipment only to devices which
have an input that is suitable for microphones.
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.
High operating voltages are required for the
tube in the microphone. Contact with the volt-
ages present in the interior of the device can
result in injury or death; therefore, the micro-
phone and power supply must be opened only
by authorized, qualified personnel.
•
•
The microphone must be operated only with
the supplied microphone cable or with a cable
of the same type. Since hazardous voltages are
generated by the power supply that can result
in injury or death, always ensure that the mi-
crophone cable used is undamaged. Damaged
cables must no longer be used, and must be dis-
abled in order to prevent injury to persons as a
result of accidental use.
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 dam-
aged during transport.
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 M 147 Tube is a condenser studio microphone
with transformerless circuit technology and a
cardioid directional characteristic.
Key features include extremely low self-noise, an
extensive dynamic range and the full, rich, warm
sound of the tube.
Typical applications of this universally applicable
microphone include dubbing, broadcasting, and
vocal and instrumental recording.

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 power supply equipment be
switched o.
Disconnect the cables.
When disconnecting a cable, always pull only on
the connector and not on the cable itself.
EN
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
period should be stored under normal atmos-
pheric conditions, and should be protected
from dust. For this purpose, use a lint-free, air-
permeable dust cover or the original packaging of
the microphone.
7. Troubleshooting
Problem
▶
Possible causes
▶
Solution
Microphone
not operating
The power supply unit is not switched on. Check the connection to the power supply
line.
The microphone is not connected to
the power supply unit or is not ready for
operation.
Check the LED status on the power supply
unit.
No signal
transmission
The microphone is not connected to the
correct microphone amplifier input of the
subsequent equipment.
Check the signal path.
Check the corresponding channel settings.
