Problem
▶
Possible causes

Solution
Microphone not
operating /
No signal
transmission
Supply voltage not activated Check the power supply device and if necessary
the associated software settings (RCS -> System ->
MicPWR).
The microphone is not connected
to an AES 42 input
Use an AES 42 input.
The microphone is not connected
to the right channel
Check the signal path.
If necessary, activate the appropriate input on the
corresponding channel of the mixing console.
The channel is muted Deactivate the mute in the AES 42 remote control.
Distorted
sound /
bad signal
quality
Excessive sound pressure of the
signal to be recorded
Take a more distant microphone position or activate
the pre-attenuation in the AES 42 remote control.
Overload due to low-frequency
interference (e.g. impact sound
or wind)
Use an appropriate windscreen (accessory). Activate
the pre-attenuation in the AES 42 remote control.
Overloading due to Plosives Use an appropriate popscreen (accessory). Activate
the pre-attenuation in the AES 42 remote control.
Sound is mu ed
and reverberant
Incorrect directional
characteristics
Check to ensure that the microphone is being
addressed from the correct side, as designated by the
Neumann logo
No
synchronization
Operation is set to asynchronous
mode
Activate the synchronization of the AES 42 input
(mode 2, RCS).
The sample rates of the micro-
phone and the subsequent equip-
ment do not correspond with one
another
Synchronize the digital input with the source.
Use a sample rate converter.
An external word clock is
detected but does not conform to
specifi cations
Check the external word clock for precision and signal
quality (e.g. check for jitter or very long cables).
Alternative solution: Use the internal DMI word clock
as the master word clock for the entire signal chain.
