NES2 use DC or AC input ?
AC.
no problem :) it uses the same adapter that an original NES uses.
It works on either but is designed for AC with a built- in Converter to DC. So either will work.
a Geneesis 1 AC will work with it

Wow, thats interesting. Is this the case with the toaster? In which case, could you not use a famicom AC adaptor with it?
Yes, they both have bridge rectifiers in the power circuit so you could use a Famicom AC adapter.
I've got a question I don't know if anyone can answer:
Why does the NES/NES 2 use AC 9v? No Famicom revision does and to my knowledge the European NES doesn't either. In fact the US NES is the only system I can think of that accepts AC 9v.
My theory is that the Japanese see us as brute rednecks that love to plug in the wrong kind of power supply into our appliances, thereby frying them. By moving the AC to DC conversion stage to the inside of the system it becomes significantly more rugged against electrical abuse.
The American SNES uses a different barrel plug than the Japanese or Euro SNES because of this reason. Have Nintendo kept the original plug for the US market, their repair centers would've been flooded with blown up systems caused by people plugging their NES AC adapter into their SNES.
Little interesting fact.
The Super Comboy uses the same barrel plug as the American Snes.
