Parameters which can be remote controlled
via the AES 42 interface
Low Cut: According to AES42 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 range is shifted by the cor-
responding value to higher sound pressure levels.
Gain: Gain is carried out exclusively in the digital
domain, thus avoiding the additional noise and
possible eff ects on the sound which can occur in
analog processing.
Peak limiter: The very fast peak limiter has an ad-
justable threshold, and prevents overloading or
clipping of the audio signal in the signal path.
Compressor/Limiter: As well, a compressor/lim-
iter with completely adjustable parameters is
provided. It can function in a broad band, or as
a high-frequency compressor/limiter (de-esser)
in one of three selectable frequency ranges. All
important parameters are adjustable.
In addition, the sampling rate, the synchroniza-
tion mode, test signals, mute, the polarity of the
output signal and the LED can be controlled re-
motely.
The software in the microphone can be updated
via the Neumann DMI. Therefore future software
enhancements will also be available to existing
customers. Please refer to the RCS manual for de-
tails concerning the update process.
5. Shutdown and Storage
Before switching off the microphone or discon-
necting the cables, reduce the volume of con-
nected equipment.
When disconnecting a cable, always pull only on
the connector and not on the cable itself.
Microphones which are unused for prolonged
periods should be stored under normal ambient
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 microphone.
