48V Phantom Feed Supply for Microphones
Of course you can use any other scheme with the regulator.

The EMU-0204 does appear to have Phantom power but it's only 5 Volts. Does anyone know if we can tap off a higher voltage from some other part of the circuit ?
Might involve cutting some traces on the original phantom power circuit I guess.
Does anyone have a circuit diagram of the 0204 ?
Thanks.
edit: Is there a low power dc/dc converter chip that can up 5 V to about 40 V maybe 5 mA. Or at least 20 V . Some easily available chip or just a sg3524/TL494 or NE555 cmos implementation ?

As well as the Rod Elliott article linked above there is some good information on interfacing precautions for phantom power designs in the phantom power articles listed here - THAT Technical Papers
