The Numark DDS is the controller part of the Numark DDS80 set (which included the DDS Drive), otherwise specifications are identical.

The DDS is a rack-mount multi-media control deck for use with hard drives, CD/DVD drives, thumb drives, iPods, and card readers. You can quickly and easily access any track in your library or any connected device because DDS gives you fast track access with text search using the click knob or the included keyboard.

Simplify your performances with Numark's exclusive Crate system on DDS' large, high-definition, backlit color screen. Crate allows you to prepare set lists in advance, on the fly, or a mixture of both. You work with Crate the same way you’d work with records or CDs, picking tracks and queuing them up to Deck A or Deck B. Profile View functionality enables you to see the track's waveform in color for fast, visual cueing.
