The C 451B is a condenser microphone and therefore needs a
power supply.
The microphone provides a balanced output on a 3-pin male
XLR connector:
Pin 1: ground
Pin 2: hot
Pin 3: return
• You can connect the microphone to balanced microphone
inputs with or without phantom power. AKG phantom power
supplies allow you to connect the microphone to unbal-
anced inputs as well.
1. Use an XLR cable to connect the microphone to a balanced
XLR input with phantom power.
2. Switch the phantom power on. (Refer to the instruction
manual of the unit to which you connected your C 451B.)
