After teasing everyone with a quick video with DJ Switch showing off the scratching prowess of a new machine, Denon DJ has finally let the cat out of the bag! Introducing the newest Multi-Media player form Denon DJ dubbed the SC3900. The SC3900 looks very similar to the current Denon DN-S3700 with a few more MIDI and controller buttons for the DJ software users. The SC3900 will be able to play CD's, USB flash/hard drives, SD Cards (speculation), and will have a Traktor mapping from the factory to support the new Cue/Sample buttons in the upper left hand corner of the unit. I'm sure almost all of the buttons including the pitch slider will be mapped to Traktor as well. The screen on this unit will most likely be an upgraded color version of the S3700 screen, but overall both players look very similar. I wouldn't be surprised if both units sport the same CD drive, platter/motor size and build, and overall dimensions. The SC3900 seems to has two separate knobs to change the start up time or stop time of the deck individually. I'm sure there are a few other upgrades that are not obvious from the pics, but we'll have a lot more information as the story develops so stay tuned!
