230V Preamp USA

@jea48 in Europe, just as in the US, people say 220, 230, and 240 interchangeably.  240 is the most common voltage.  I hope electricians aren't getting a knot in their shorts over this nomenclature.

@jea48 let me know what else qualified electricians cannot do what can be routinely done.

Thanks for the responses. I can’t run a 220 line. I have a timber frame house and the outer walls are SIP panels which are solid. I was going to call the manufacturer today to ask about switching voltage but I didn’t have time. Likely just going to buy a step up transformer.
