▶
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
connected 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 transformer out-
put. The -pin XLR connector has the following
standard pin assignments:
Pin 1:
0 V/Ground
Pin :
Modulation (+phase)
Pin :
Modulation (–phase)
