What on earth is ‘phantom power’?
Phantom power is 48V for powering condenser mics, and is supplied via the same XLR cable as the mic signal. Usually mixers offer phantom power, and at the mic end it is filtered out of the audio signal.
So if you are plugging into a mixer with phantom power, it can power your Sansamp.
On a separate note, I haven't use any of the bass units, but I remember trying one of the original units in a friend's studio, and found it did sound like an amp, but I felt it made the sound quite mushy. I suppose some people like that though.
