I checked the manual and it does not state what input voltage's are usable ????? , look on the back of the unit it should state the usable voltage range of the 2480 ( a universal PS works from 90-240ac )
If it is a fixed voltage unit it will also say on the back.

Thanks Buzz,
I can't ay roland are too precise when it comes to showing these details: the unit comes with the warning sign, the usual warning sentences but NO indication whatsoever on the voltage...
or well, yes...on the upper right corner of the base of the unit (below the screen), there's a sticker with model no., serial no. and the following info:
"Roland ED Corporation
AC 100 V~50/60Hz 80W"
Electricity is not one of my strong sides, but I feel the info is a bit confusing...AC 100 = 100V? how many A:s (or mA:s)?? 80W???
I've resent an e-mail to the people who sold the unit to me in order to get more specific info, if not a specific transformer-model I can use here in Europe. The deal quite a lot with Europe, so I hope there won't be any problems....I'll post whatever happens in order for it to be available for other planeteers.
Anyhow, if anybody can translate the Roland "language" on the sticker, you're welcome

"Power Consumption: 80W (AC 117/230/240V)"
Found this on http://www.roland.com/products/en/VS-2480CD/specs.html
Seems like the only thing needed would be an external AC adapter that could deliver 80W at one of those voltages...
Still searching though -> any comments?
I hope to be able to come across this little backlash ASAP, cause I can't wait to use this machine!!!

If you take the AC100~ 50/60hz literally it means it is a 100volt AC unit ( 80W = approx. 0.8 amps @ 100v
) this may be a special Japanese unit for 100vac . if that is the case you need a transformer from whatever your voltage is to 100vac !!!!!!!
E-mail Roland to see if they can give you a definite answer.

The amp load is pretty irrelevent when dealing with transformers. Even a small 300 watt 1.6A 230-110v would suffice except for your looking for 100v.
if the amp load on the transformer is 1.6, 5.0, 8 etc this is the point where the fuse will blow
and the watt load is the same.
Basicaly you can stack up equipment into one transformer but youll have to do the math on every piece of gear to be sure your not exceeding the amp or watt load on the transformer....or simply the fuse will blow
I own 5 various transformers from a German company called TRAMAG (couldnt find on Internet) phone (09 11) 9 30 61-0.
All my gear is 110-115 U.S. standard and I live in Italy.
These things work great (alittle noisy) except the plugs are SCHUKO so I had to buy some adapters for these crazy Italian sockets.
good luck

CONCLUSIONS & SOLUTION
Buzz, Gamble -> thanks a lot for your inputs!
Finally, I bought a 230->110V adapter with 100W charge. Talking to various technicians and electricians, this solutions seemed best: in Spain, don't know if in the CE in general, there doesn't seem to be certified 90-240V Universal Transformers, and none give a charge of 80W. The one I finally bought has it's PEAK at 100W, and according to the eletrician who sold it to me, going with a 50W charge would blow the transformer, but using a slightly higher charge shouldn't give ANY problems at all (as you said Gamble?)
Nonetheless, once the problem solved, here comes some issues I encountered that don't put Roland and some Roland Technical Support (at least in Europe) in a very good place:
1. Searching through the net, I found out that at least some Roland VS:s (if not all, check out the sticker ON your internal power supply to find out, not the sticker that comes outside -> you'll need to open the VS) are Universal, a bit like Apple Mac Computers: they recognise the voltage charge that comes in and adapt their entry or something like that...to put it short, you quite probably can even plug your Roland VS wherever you are in the world, with any voltage between 117V and 240V.
2. Don't get trapped by some bad intentioned tech-support (no offense meant to honest ones, just dashing some "bad" guys); I heard several cases of VS owners here in Madrid who opened up their VS:s after being told by the local Roland Support in Madrid that they'd change the internal AC Power Supply for 100€ or more; what they found out was that the Roland internal supply worked fine with voltages from 110-240V...nevertheless, check this is the case with your VS before trying anything! (I'm not sure mine is universal, since it might be a japanese non-export version...I took the safe way and bought myself an adapter...). The thing is that the guy wanted money for doing absolutely nothing, and that I was redirected to him by Roland Spain [AT-Music, Madrid]!
CONCLUSION #01
If you live in Europe, a 220->110V, 100W AC Transformer for around 15-20€ should suffice to use with a japanese Roland VS (it works for me, with no particular "buzz" or sound either)
CONCLUSION #02
If you want to make sure what voltages your Roland VS2480 (or other VS models) tolerates, check it out inside the machine, on the actual power supply (be aware that your I think your VS won't be covered by your guarantee if you open it up...)
OK, a long post for a minor issue, I guess that's my ID-check as a beginner
Hope this helped anyone (it sure helped me in the end!)

I think you still maybe are mis-understanding transformers a bit.
Basicaly the more watts the better as long as its in you voltage range.
If your running 80watts through a 100watt tranformer then you are on the right path becasue that gives you a 20% buffer of the max watt load on the transformer...makes them last longer (they generaly dont have a huge life span).
But the problem here is that you can not plug anything else into this tranformer....maybe you dont need to.
If you can afford it Id highly reccomend getting one with a minimum 300 watt load (1.6 amp) at around 60 Euro/dollars.
This way if need be you can plug in at least a couple more peices of equipment if nessesary....staying within the 20% buffer max watt output of course.
But more importantly...more is better....in this case giving yourself a larger buffer area, increaseing the life span of the transformer.
As a side note I would also reccomend a power conditioner after the transformer (Furman sells some cheaper models...that DO work)....reason being is even thought he power is somewhat regulated it is still very dirty if not more dirty (i.e. RF interferance) after going through a transformer.
Hope you bought some extra fuses cause you'll need them

Qoute:
"(it works for me, with no particular "buzz" or sound either)"
Assuming your using a transformer and NOT a step up/step down converter you can do this little test on your ears.
1. Turn on the transformer listening to it....you'll hear a "boing" or "pump" noise when it turns on.
Turn it off
2. Again listening turn it on...notice that there is a buzz/hum within the "turning on" sound
which only lasts for a split moment then dissapers instantly
Turn it off
3. Turn it on again and listen....that hum didnt really go away did it?
The reason you may not have heard it before is because its within the 50/60Hz range...which damn near everything that uses electricity has this freq of hum...youve been hearing it everyday for your entire life....your brain has gotten used to it so easily ignores it.
Its like blinking...you dont usualy know your doing it...but you are (well now you notice because I said it) but because you've been doing it your whole life your brain can convinietly ignore it.
I am no golden eard audiophile but I find stepping out of the box like this can open you up to hear more things.
If this worked for you the only problem now is that you will now hear it in everything, all the time.....and it will annoy you until the day you die.

I am told that every VS has an universal powersupply, you don't need any transformer at all. just plug in anywhere around the world. Got this information from my vendor.
And, I agree with Arjen,
use a UPS
