POWER SUPPLY:
12VDC Centre Positive - 1.25A (required for full 48V Phantom Power)*
* iD14 requires a lot of power for class leading converters and class-A microphone preamplfiers. We could not beat the laws of physics so an external supply is required for 48V phantom power. Your microphones will thank you when they get enough voltage!
