I really don't like SMPS's because I don't know enough about them, I am way
out of my comfort zone here.
But, most modern audio equipment (I only know audio equipment) using SMPS's
use small IC's as the controller, which are designed to tolerate almost
anything thrown at it.
They will only attempt to power up once they have enough voltage to do so,
and will shut down if excessive current draw occurs, without destroying
anything.
You can usually power them up with a Variac and lightbulb, but with the
JBL's you can't, because I believe they have added some relay circuitry that
makes this not possible.
I'd just like to know what that is.
