While you're correct that the unit is expecting AC, no harm will be done by throwing DC at it. You just need to make sure that you provide enough voltage (measure what comes off the bridge rectifier inside, you need to add a little to that, as that bridge will drop your incoming DC voltage a bit) and current (says 0.5A on the back, that seems easy enough).
The nice thing about having that AC socket on the back is that you don't have to worry about the DC polarity. (Tip hot or tip negative, doesn't matter)
There's a slight chance that there's a voltage doubler tucked in there, though it's very unlikely, so you'll need to do your homework before you get too carried away! If there is a voltage doubler, I wouldn't bother trying to get an external DC supply to work.
