Deemed "the world's smallest premium DJ audio interface," the Traktor Audio 2 is Native Instruments' new audio interface which boasts 24-Bit/48-kHz sound in a package about the size of a deck of cards.
The Traktor Audio 2 offers four-channels of digital-to-analog sound conversion, with a dedicated headphone output and a stereo line output allowing for connection to DJ mixers and other external equipment. The USB-powered device also comes iOS ready, making it able to be powered directly by an iPhone or iPad.
