trol Software, the LEDs c an be set to four diﬀ erent

brightness levels or switched oﬀ .

When connecting the cables, ensure that the con-

nectors are locked correc tly.

Long cables and multiple connectors lead to a

drop in the supply voltage and to a deter ioration

in jitter behavior, particularly in the case of high

sampling rates. Therefore, to the greatest extent

possible, use continuous c able between the mi-

crophone and subsequent equipment, and for

longer distances use AES /EBU cable exclusively

(with an impedance 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 op-

erated in synchronous mod e (Mode 2), whether or

not sample rate converters ar e used in the subse-

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

jitter suppression in the DMI. Also, the output of

two microphone signals as on e AES 3 stereo sig-

nal is possible only if the microp hones are syn-

chronized with one another.

Parameters which can be remote c ontrolled

via the AES 42 interface

Polar pattern: Switching the p olar pattern is

achieved by varing the polarization voltage of the

rear capsule half. During the re loading process

the microphone is temporarily muted.

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

ting 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.

During the reloading proce ss the microphone is

temporarily muted.

Gain: Gain is carried out exclus ively in the digital

domain, thus avoiding the additional noise and

possible eﬀ ects on the sound which can oc cur in

analog processing. The switching process is click-

less.

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: As well, a co mpressor/lim-

iter with completely adjustable parameters is

provided. It can function ov er a broad frequency

range, or as a high-frequency compressor/limiter

(de-esser) in one of three selectable frequency

ranges. All important par ameters are adjus table.

In addition, the sampling rate , the synchroniza-

tion mode, test signals, t he polarity a nd muting of

the output signal and the LEDs can be controlled

remotely.

The software in the microphone can be updated

via the Neumann DMI-2. Therefor e software up-

dates are also available to existing customers.

Please refer to the RCS manual for d etails con-

cerning the updates.

5. Shutdown and Storage

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.
