Thank you for the info, but I've tried plug adaptors, voltage converters, transformers and none of them work. I think there may be something wrong with the station itself. I appreciate all of your advice, but now I'm afraid I'll either have to send it back to the seller or get it fixed.

Dear Melisa: Dick's info is most likely correct.
I am intrigued by the "wheel on the back". Have you tried to turn it? Sometimes it is a built-in rotary switch which needs only to be turned to automatically change from 220V to 110V. If that is so, all you may need (once switched)is a small plug adaptor which changes the European plug from its round prongs to the flat prongs used here in the USA. Post a follow-up message in this Forum so we can learn from your experience. Thanks.

Hello,

You're correct the DX7 I have, has a wheel on the back that has 120V or 220V selection. The seller told me to buy a transformer that converts 120V to 220V, so I did. But it still isn't working. The transformer/voltage converter that I purchased is the third one down on this page.

I'm still not sure if it's the DX7 that's not working or I once again bought the wrong converter. Please help! Thank you again for your response, I really appreciate it!

by: Dick Rector

Hi Melissa,

Have a close look at your powersupply. If it says something like: INPUT 100 - 250 volt
You can use it safely in the US because it has a multiple voltage input like most notebook computers have these days. You only need of course an (travel)adapter to fit the American type wall outlet.
However if is says only: INPUT 220/240 volts this powersupply will not work in the US on 110 volts.
In that case you have to find a new one.
Hope this helps you, let us know please,

Regards
Dick
