Troubleshooting

▶
Problem Possible causes
Microphone not Supply voltage not activated
operating /
No signal
transmission
The microphone is not connected
to an AES 42 input
The microphone is not connected
to the right channel
The channel is muted
Distorted Excessive sound pressure of the
sound / signal to be recorded
bad signal
Overload due to low-frequency
quality
interference (e.g. impact sound
or wind)
No Operation is set to asynchronous
synchronization mode
The sample rates of the micro-
phone and the subsequent equip-
ment do not correspond with one
another
An external word clock is
detected but does not conform to
specifi cations

Solution
Check the power supply device and if necessary
the associated software settings (RCS -> System ->
MicPWR).
Use an AES 42 input.
Check the signal path.
If necessary, activate the appropriate input on the
corresponding channel of the mixing console.
Deactivate the mute in the AES 42 remote control.
Take a more distant microphone position or activate
the pre-attenuation in the AES 42 remote control.
Use an appropriate windscreen (accessory). Activate
the pre-attenuation in the AES 42 remote control.
Use an appropriate popscreen (accessory). Activate
the pre-attenuation in the AES 42 remote control.
Activate the synchronization of the AES 42 input
(mode 2, RCS).
Synchronize the digital input with the source.
Use a sample rate converter.
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.
