Vintage Synth Repair

Hi All.

I have a question. I just received an Arp Odyssey (Whiteface) in the mail today i bought 
from Canada. I live in Denmark (Europe)

The wall-plugs here is different, and we have 220 V in stead of 110 V. I have a converter 
for the PLUG ONLY, but Do i also need an external converter to convert my power from 
220 to 110 V before i plug it in? I'm not sure if the Arp adjusts itself?

From this diagram i found, it looks as if the Arp can tale 115-230 V - but I'm not sure this 
is right. Can anyone please help me with this?
