Confusion about DJM-2000 Nexus input power requirements (120v, 240v or auto?)

Hello,

I've seen many questions here and there. And all are somehow unsolved. I am currently using my DJM-2000 Nexus + CDJ-2000Nexus on 110v. However, my monitors are running strictly with 220V and I want to make a recording. If I plug them together with the XLR cable, some cracks occur on audio - and this is expected because of phasing problems I suppose.

The thing is -- and this has been asked many times -- I want to be perfectly sure that I can plug my mixer in a 220V output. User manual says 120V input only. But hardware itself says otherwise. Also there is not a voltage switch anywhere.

As this is no cheap stuff, Would like to hear from you. 

Thanks in advance.
