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
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 amplifi 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 amplifi er
Decrease the input sensitivity or gain of the
subsequent amplifi er so as to provide suffi cient
headroom
Wind eff 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 muffl 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.

The microphone has a balanced, transformerless
output. The 3-pin XLR connector has the following
standard pin assignments:
Pin 1: 0 V/Ground
Pin 2: Modulation (+phase)
Pin 3: Modulation (–phase)
