I'm about 95% certain that it does NOT take line voltage in. It just has a
different internal power supply assembly that only uses one of the
low-voltage AC inputs from the external power supply instead of both. As
far as I've ever heard, there was no 99/4 or 99/4A that did not use an
external power supply.

If it were mine, I wouldn't even consider pluging it into line voltage
until doing a lot more research on exactly what's inside.
