well as the two-channel Dig ital Microphon e Inter-

face (DMI-2) with the accompanyin g RCS control

software for remote controlling all microphone

characteristics (see also the “Technical data” sec-

tion).

The consumption of power resul ts in slight warm-

ing of the microphone, which incr eases with

shorter cable lengths and hi gher sampling rate s.

4. Setup

Mounting the microphone

Attach the microphone to a stable, sturdy stand.

Use an elastic suspension , if necessary, for the

mechanical suppression of structure-borne noise.

For this purpose set the micropho ne into the inner

cage from above, and secure it to the inner cage

with the threaded nut. If requ ired, use a wind-

screen or popscreen from our r ange of accesso-

ries in order to suppress win d or pop noise.

Connecting the microphone

Caution: An incorrect supply voltage can dama-

ge the microphone!

Connect the microphone to microphone inputs

and to equipment which supplies ph antom pow-

er in accordance with AES 4 2. See also chapter

“Safety Instructions”.

Caution: Very high signal levels can damage

loudspeakers and your hearing!

Reduce the volume of connected playback equip-

ment before connecting the microphone. This is

also advisable in order to avoid acoustic feed-

back.

Connect the microphone by mean s of an XLR cable

to the AES 42 microphone inpu t of the DMI-2 Digi-

tal Microphone Interface, to the Neumann con-

nection kit or to other audio e quipment along to

AES 42 standard.

Concerning the connectio n of DMI-2 and Connec-

tion Kits with your audio device please consult

the respective operating manuals.

With a correct power supply, a blue L ED on the mi-

crophone indicates that the microphone is ready

to operate. When the microphone is switched

on, the LED at ﬁ rst glows dimly, and after a short

time shines with the preset brightness. When the

DMI-2 Digital Microphone In terface is used, the

LED can be set to four diﬀ erent brightness levels

and switched oﬀ by means of the Remote Control

Software.

When connecting the cables, ensure that the con-

nectors are locked correc tly.

Address the microphone from the side on which

the Neumann logo is located.

Gradually increase the volum e of the connected

equipment.

Long cable s and m ultip le con nect ors le ad to d ete-

rioration in jitter behavior, particularly in the case

of high sampling rates. Therefore, to the greatest

extent possible, use continuous cable between

the microphone and subsequent equipment, and

for longer distances use AE S/EBU cable excl usive-

ly (with an impedance level of 110 ohms).

Ensure that the microphone and al l equipment in

the digital signal chain are sy nchronized. If the

Neumann Digital Micropho ne Interface is used,

the connected microphone s should always be

operated in synchronous mode, whether or not

sample rate converters are us ed in the subse-

quent signal chain. This w ill ensure very e ﬀ ective

jitter suppression in the DMI (as o f hardware ver-

sion 3). The output of two micropho ne signals in

an AES 3 stereo signal is also possible only if the

microphones are synchronized with one another.

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 ha zardous sound

pressure levels.

Parameters which can be remote c ontrolled

via the AES 42 interface

Low Cut: Acccording to AES 42 there are four set-

tings for the low cut: oﬀ , 40 Hz, 80 Hz and 160 Hz.

Pre-attenuation: Pre-attenuation is achieved by

reducing the capsule voltage. If pre-attenuation is

activated, the dynamic ran ge is shifted by the co r-

responding value to higher soun d pressure level s.

Gain: Gain is carried out exclus ively in the digital

domain, thus avoiding the additional noise and

possible eﬀ ects on th e sound which can occur in

analog processing.

Peak limiter: The very fast peak limiter ha s an ad-

justable threshold, and prevents overloading or

clipping of the audio signal in the sig nal path.

Compressor/Limiter: A compress or/limiter with

completely adjustable parameters is provided.

It can function in broad band mode, or as a high-

frequency compressor/limiter (de-esser) in one of

three selectable frequen cy ranges. All import ant

parameters are adjustable.

In addition, the sampling rate , the synchroniza-

tion mode, test signals, m ute, the polarity of th e

output signal and the LED can be co ntrolled re-

motely.

The software in the microphone can be updated

via the Neumann DMI-2. Therefor e future soft-

ware enhancements will also be available to ex-

isting customers. Please r efer to the RCS manual

for details concerning the upd ate process.

Suppressing noise interfer ence

The frequency response of t he TLM 103 D extends

below 20 Hz. The microphone is of c ourse corre-

spondingly sensitive to low-frequency interfer-

ence such as structure-b orne noise and wind or

pop noise. Depending upon the s ituation, the use

of an elastic suspension, a w indscreen and/or a

popscreen is therefore recommended.

5. Shutdown and Storage

Before switching oﬀ the microphone or discon-

necting the cables, redu ce the volume of con-

nected equipment.

When disconnecting a cable, always pull only on

the connector and not on the cab le itself.

Microphones which are unuse d for prolonged

periods should be stored under normal ambient

atmospheric conditions, and should be protected

from dust. For this purpose, use a l int-free, air-

permeable dust cover or the ori ginal packagi ng of

the microphone.
