Nearly all consumer electronics are built for international voltage sources. It is more cost effective to have a single product line with selectable voltage input than separate power supplies for US vs. international. Because of US regulation, the manufacturer must identify the equipment as 110v only, but don't let that deter you.

The NC-200A manual indicates that the input voltage is selectable, but it doesn't say how. It may just be a fuse, or a jumper somewhere inside. I would contact someone at Eden or the Eden forum.

A thread on the forum for a different amp indicates internal jumpers: I'm guessing it's the same for all amps.

I guarantee you'll need a different fuse, so here's a link to their fuse sizing:

The manual for the LDS110 hints at two power ranges. I'd be willing to bet that this is also the case of an internal jumper setting, and you should contact Line 6 for specifics. Look for a sticker with the voltage printed on it: lift the sticker and see if there is a switch underneath it. This is the way JBL did it on their first generation EON powered speakers. The sticker made it kosher for the US, and they just used a different sticker to make it international.
