The Phantom I is not a masked vigilante but is, in fact, a useful box from ART for providing phantom power where there is none. Phantom power is required by most condenser microphones and is usually supplied by your desk or audio interface. However, in situations where this is not possible the Phantom I comes in extremely handy. The Phantom I supplies phantom power within+/- 2V of 48V and so, powers most microphones although, it's always worth checking with the manufacturer first!
