I signed up to ask Roland Canada and saw that the question had already been asked and answered (more explicitly than the response from Roland US, IMO) :
Q:
My Japanese friends give 3 sound modules while I visited them .They are Roland SC8850,SC-D70 and Edirol SD90.These modules all bought in Japan before.
Can I use them in Canada where power is 110V (not 100V )?
A:
All three products have internal switching power supplies. As a result you just need the proper AC cable which you can purchase from our Parts Department at rcm.parts@roland.com
The SC-8850 will simply need a polarized 2-prong 117v power cable.
The SC-D70 will simply need a 3-prong 117v power cable.
The SD-90 will simply need a 3-prong 117v power cable.
