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.

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.
