Ok, I guess nobody uses one of these or the question is too obtuse. I discovered my IPOD AC adaptor powers the USB in on the 122 nicely. One question if anybody is reading this...how can a device such as this that uses USB 5v/500Ma power, provide phantom power for condensers? Do they step up the voltage or is it just passing the 5 volts to the mic and it works because 5v is enough for some condensers. Anyone? Mics used successfully, a pair of CAD 1200, and a pair of M-Audio Lunas.
