7. Troubleshooting
Problem
Possible causes
Solution
Microphone not
operating
The phantom power supply voltage is
not switched on at the mixing console
or at the power supply equipment
(LEDs not lit up).
Check the corresponding channel settings
The power supply equipment is not
connected to the power supply line or
there is no battery
Check the connection to the power supply
line or check the battery of the power supply
equipment
No signal
transmission
The microphone is not connected
to the correct microphone ampli er
input of the subsequent equipment
Check the signal path
If necessary, activate the appropriate input on
the corresponding channel of the mixing console
Distorted sound Incorrect input sensitivity or gain
setting of subsequent ampli er
Decrease the input sensitivity or gain of the
subsequent ampli er so as to provide su cient
headroom
Wind e ects Use an appropriate windscreen (accessory)
Plosives Use an appropriate popscreen (accessory)
Transmission of structure-borne
noise
Use a suitable elastic suspension (accessory)
Sound is mu ed
and reverberant
Incorrect directional characteristic Check to ensure that the microphone is being
addressed from the correct side, as designated
by the Neumann logo.
