Thanks for the question. It should be dual voltage, but let's take a look at the back of the system to make sure. On the label on the back of the bass module, there should be a voltage listing that says something like "100-240 V, 50/60 Hz". Do you see this, or something similar?
If you do see that, that means the system will work on any voltage in the world, you will just need a plug adapter for the EU plug.
