Resumen: El Numark NDX 400 es un reproductor de mp3 y cd, especialmente utilizado por Djs, ya que con este aparato se puede scratchear un cd como si fuese un vinilo, también se puede reproducir música a traves de un usb. El producto en mi opinión es una maravilla, ya que tiene todas las ventajas de un plato de dj con vinilos pero ninguno de los defectos que puede tener, como es que se te salten las agujas, o que el vinilo vaya cogiendo suciedad que acaba llegando a la aguja.
Resumen: I love this thing! One of the best purchases I have made. It's fantastic. It does everything it advertises and then some. The scratch feature works perfectly, with pin-point accuracy. Even better than vinyl turntables on the scratch, since there is no skipping. I love the fact that it also plays MP3 USB Flash drives just like CD's, with all the bells and whistles.
Resumen: I was looking for a cd player to hook up to my mixer and play backing tracks. I did a ton of research and was never happy with any of the choices I found. I was using my BluRay DVD player to play cd's and it was a real pain to get it to work right. Then I ran across this thingie from Numark and from the description, it appeared to be what I was looking for. So I bought it! $190.00 with Prime's free two day shipping.
Resumen: this can do what i want it to, IE play mp3's and I know how to beatmatch so no problem. It took a few hours of practice, but not that hard to move from turntables to these. The only problem was I got the first one, and it didn't work at all. I have heard other people complain about this. I then went ahead and got the multi year warranty, just in case. Otherwise for what they are they are good.
