Audio Connection - AKG CGN 99 C/S Modo De Empleo

1. Use a shielded balanced cable to connect the micro-
phone to a microphone input with phantom power.
2. If the phantom power on your mixing console is
switchable, switch the phantom power on. (Refer to
the instruction manual for your mixing console.)
The microphone is powered directly from the phan-
tom power source.
If your mixer has no phantom power, insert an external
phantom power supply between the DPA phantom power
adapter and mixer input. We recommend the optional
B 18 power supplies from AKG. Using any power sup-
plies not recommended by AKG may damage your
microphone and voids the warranty.
You may also consider having a qualified technician
retrofit a phantom power supply as per IEC 61938 to bal-
anced or unbalanced mixer inputs. The IEC 61938 stan-
dard specifies a positive voltage of 12, 24, or 48 V on the
audio lines versus the cable shield.
If your equipment inputs are grounded or transformer-
less, wire either capacitors or extra transformers into the
audio lines as shown in fig. 9 above in order to prevent
any current leakage into the input stage.
