i have bought a new cdj800 mk2 recently and when it was delivered i was out. my brother got a normal british plug(240v) and pluged it into the cdj power socket which operates under 120v and he said it switched on and then turned itself off after about a second. i have two questions

1) will 240v have damaged my cdj in any way?

2) do i need to use a step down convertor to operate it (240v->120v)

thanks
