Numark has something for the "old-school" rack-mount dual CD Deck DJ's for NAMM 2011 as well. Introducing the newest dual rack-mount CD Deck called the Numark CDN77USB. The USB part is obviously added to the name so that DJ's can use USB drives for audio playback instead of using only CD's. This is a welcomed update for mobile DJ's who want to still play their CD's, but also want the option to add tracks directly from their computers via USB flash drives. Press release and pricing details inside.
