Super simple setup, it's plug & play, no need to read the manual even if it has the merit of being present.
I find the knobs too close compared to Z1 in NI. the plastic shell not really give a solid impression, but I think it will because it will be released only for travel between 2 dates. No evening at risk.
Against by the quality of the knobs is really impressive, it feels solid, full nose. No parts of the game.
The quality of the sound card is good, after that will depend on your sound. I mix as AIFF, so for me it's good.
Only downside, the output level is really low because the card is powered by the USB port.
Equalization is good, it cuts well and has a touchsensitive "Kill" function. this gadget is, but it's not bad when you want to make small cut quickly.
I use it for 2 weeks.
I tried the Z1 with Traktor because it was the only mixer travel. The app is really not for me, I hate him.
This mixer suit every DJ who wants to use only traveling and at home. Unable to make an evening with it.
I have not hesitated to buy this because I AMX expects that long ago. I use Serato since 2005 (ie since the beginning), out of the question for me to move on Traktor.
I am fully satisfied and do it again this choice without hesitation.
