22 C 414 XLS / XLII
3 Powering
The C 414 XLS and C 414 XLII provide extremely low self-noise yet high headroom. The
only way to meet these strict engineering requirements was to limit the powering options for
both microphones to 48 V phantom power to IEC 61938 only. This standard requires a pos-
itive voltage of 48 V with reference to the cable shield.
• Do not connect the microphone to any power supply other than a phantom
power source (input with phantom power or external phantom power supply)
to IEC 61938 with a floating connector, using a balanced cable with studio grade
connectors to IEC 268-12 only. This is the only way to ensure safe and reliable
operation.
