I have had my one some time now (this model has been around some time) and have been happy with it but I think if I was starting again I would get something different.

If your doing a lot of DJ mixing and constantly playing with the sliders I don't think the sliders are of the highest quality as mine can be inclined to hit a dead spot at the extreme top end.
Also RCA video in or out is a bit of old technology in todays world of HDMI.

It has plenty of inputs for other audio gear and 4 mike inputs for karaoke so see no reason why it would not work with the Numark mix track pro but why would you need it.
The main reason I bought mine some years ago was for the video mixing, I was playing a lot of music videos via a video player rather than my laptop which at that time would easily overheat from constant video playback, with the faster processors and graphic cards in todays laptops I can play all the videos direct from laptop in VDJ or Hoster so don't really require the video out capability of the vocopro mixer.

So if you require top quality sound more than the video connections I would look for something else, Lonman seems quite knowledgeable on mixers and sound equipment perhaps he will join in and advise you.
