Technically, phantom power for a microphone is going to a preamp circuit =
that just happens to live in the microphone.

Considering that DI products are almost always used in a situation where =
phantom power is available, and potentially even where wall power =
outlets might be in short supply, it makes sense that DI designers would =
include the option to power everything from phantom power.

In addition, since phantom power is (supposed to be) 48V, that=E2=80=99s =
a lot more power for a preamp than, say, the +/-16V of 500 Series =
modules.

Granted, there are plenty of preamps that are in full 19=E2=80=9D rack =
enclosures with dedicated power supplies.
