I was in Slovakia last week to play a rave somewhere in the mountains. I brought my S4mk2, and it worked great. My friend used a Z1 mixer and a laptop only. I was impressed by the minimalistic setup. I already have an X1, and having a Z1 next to it seemed a lot less clunky than packing my S4 in a big suitcase and pay for extra luggage so I just bought a Z1.
However I noticed that he had an input for a power adapter next to the rca main out on his z1. On the one I ordered there is only USB. What am I missing? Should I worry? When did NI change this? Is the one I ordered some sort of mk2 or something?
His Z1 was working fine with my laptop also and he did not use a power adapter, just a usb cable.
