M-Audio Torq Conectiv USB DJ Interface

Conectiv, developed by M-Audio's SynchroScience division, is the world's first bus-powered 4 x 4 USB audio interface designed for DJs who perform and produce tracks with a laptop.

Together, Conectiv and the included Torq software form the ultimate DJ tool --high-fidelity audio, all the right kinds of I/O (including dual phono preamps), and the ability to mix, beat-match and cue digital files with ease.
