Default How to rewire Soundcraftsmen Pro Power 4 from 220v to 110V?

I recently purchased this amp and while it has a typical U.S. 3 prong plug it has a factory sticker stating that "this unit is wired for operation on 210 to 250 volts ac, 50 to 60 HZ. It can also be wired for operation on 110 to 125 volts ac, 50 to 60 hz. Rewiring instructions are given in a special instruction sheet available from the factory."

The amp works on 110v but I would of course like to make sure that it is wired correctly for 110v. Anyone know about the special instruction sheet or how to know whow to rewire it for 110V?

If it has a US plug and works correctly on 110V i would say the chances are, it's already been rewired. It would not function correctly on half the voltage otherwise.

Most likely someone has already rewired it and not removed the sticker.
