Have you got the phantom power feed enabled?

Exactly, the EMU 0204 seems to lack phantom power for the XLR input in which case you will not be able to use the ECM8000 directly. You will need to apply phantom power externally.

I'm having the same problem, so glad I found this thread. How would one go about applying phantom power externally?

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

I did find a 555 circuit using 9 V. I posted it somewhere on the forum.
A smaller circuit would be nice as we can put it into the same case as the 0204.
Maybe a flyback boost circuit is needed to get over 20 V from 5 V.

A circuit of the 0204 would be really helpful.
