Conections noon, optic, USB, line in, headphone.

Instalation easy drivers available on the manufacturer. I reinstalled many times and no bug to instal.
It can be used either in controller or in sound card, or a combination of both but nimporte which case the connections are easy

VDJ is in rel. the same buttons, fader ...
the knob are quite prcis, the faders can galements although flexible.
both drives are convenient pout stall tracks but do not expect to scratch with.

I used to annimation small parties with friends or family and is Extremely pratoque. Of course it is not material "pro" but to have fun with VDJ and make good combos is almost indispensable.
The output quality is good.

The price remains but one can raise one's PC and VDJ, you will have what Russia a good musical entertainment.
