Unfortunately I didn't read the bit about "products sold by Sam Ash use the standard 120V/60Hz voltage standard"..I thought that stuff was long gone, as all the other international purchases of electronic music equipment have been 110/240 auto selection or switch selection. The manual says 110/240, but the Mackie SRM550 is only 110v.. and in my hurry to hear what it sound like i plugged it in and blew it up. Any saving on the this international purchase will be well and truly lost by the repair cost (if it is repairable) and the step-down transformer I will have to get and carry around with me. I accept responsibility for not reading the fine print, but as a responsible retailer making international sales you should have questioned my purchase, or put 110volt in the main description at the top of the page, or offer an international version of the product. It's hard to express my dissatisfaction with this sale without swearing.
