[Kenwood] Wanted info about dsp-100

[Allan]

Hi all,
I look for on internet but don’t find any answer about this question.
Is it possible easy for changing the voltage of the dsp-100 ( 120 volts to
220/230 volts ) ? 
There is just a switch to turn on some power-supply or a easy system like on
the tl922 ; maybe this is a easy system too ?
I live in Europe and I find one to buy from USA.
Many thanks  for any answer,
Regards
Allan
