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.
Resumen: This is my first CD player for DJing. I have been using two of them at raves and anime conventions for about three to four years. The beats per minute detection system is not quite as trustworthy as the more expensive Pioneer CD players.
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.
