Mungo Sync Z PSU information please?

Hello guyz

I just got a Mungo Sync Z

But it came with no documentation and no power supply…

The PSU is no problem but I need to know the polarity it needs?

Second question is… The four DIN sockets… Wich one are midi in/out/thru and wich one is Sync?

The Mungo website have no information about it,

Of course the DIN sockets question I could figure out by myself, but still need to know the PSU polarity,

Anyone knows this please?

Thanks!
