▶
Problem Possible causes
Microphone The phantom power supply voltage is not
not operating switched on at the mixing console or at the
power supply equipment.
The power supply equipment is not con-
nected to the power supply line or there is
no battery.
No signal The microphone is not connected to the
transmission correct microphone amplifier input of the
subsequent equipment.

Solution
Check the corresponding channel settings.
Check the connection to the power supply
line or check the battery of the power supply
equipment.
Check the signal path.
If necessary, activate the appropriate input
on the corresponding channel of the mixing
console.
The microphone has a balanced, transformerless
output. The -pin XLR connector has the following
standard pin assignments:
Pin 1: 0 V/Ground
Pin : Modulation (+phase)
Pin : Modulation (–phase)

valid for clean and well-looked-after microphones or
microphone capsules, respectively. Any kind of pollution
of capsules and membranes may restrict the said values.
