I have the opportunity to buy a 220V Crown XLC (install series) amp that was intended for the European market. I live in the US where mains are 120V single phase, and this amp wants to run off of 220V single phase. There is no external or internal "mains voltage" switch on these models.
I have read online that for the very similar XLS series it is a matter of changing a jumper and some other components (some are SMD), and I have info on part numbers for that. Unfortunately for the XLC series I do not know part numbers and PCB locations, and the board do look a bit different, so that might be a dead end. Also you need to remove the PS board do SMD work, so it might be a PITA overall.
Since I might actually move to Europe someday, it might make sense to keep the 220V mains input for the amp intact and use a voltage converter while I am in the US. These are a large 2:1 step up/down autoformer type transformer. But I am not sure how well suited (or safe?) it would be to use an autoformer upstream of a class-D power amp that can pull a lot of current at the waveform peaks and is not a steady-state AC draw. Is this unwise?
Also, if/when I move to Europe (Germany) I will likely bring a lot of my 120V US gear over there with me, so I would then need to step down the voltage for any equipment that I could not convert internally. Having a large (several kVA rated) step up/down transformer would useful for that, if it is appropriate to use one with audio gear.
Thanks, any insight would be appreciated.

Let me rephrase:
Can I use a 1.5kVA or larger autoformer to run this 220V single-phase amp from my 120V single phase mains successfully?
Nobody has anything to say about this???

Hi, I think you can use the stepup auto transformer to step up the main voltage from 120Vac to 220Vac to get the XLC amplifier work normally. And I would recommed 2KVA xfmr for XLC2500 and 3.5KV for XLC2800 if you want the full output.
220v crown2800 in USA
I have a slightly related question about using 220v XLC2500/2800 in the USA.
Can i run the usual 240v circuit from the panel and use this 220v amp without problems? The manual does show 100v, 120v, 220v and 240v all sold as different models. But I don't more if that's just for selling in different regions or actually any different internally? Any ideas?
