i'm sure you've already done this, but just to make sure, double check to see if any of your equipment has a switch on the back to convert it that way - that's the easiest, obviously. then all you'd need would be a plug adapter.
i'd also shoot an email to the companies, that's some nice gear and it would be good to see what they say - especially the logans, they would seem the trickiest to convert.
best of luck.
