Some Remarks on Microphone Maintenance

The Neumann online forum on our website en-

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 diuse-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.
