Numark M6 USB Four-Channel USB DJ Mixer
M6 enables you to step up to a four-channel mixer. This club-style design not only works with any standard audio sources including turntables and CD players, but it also has a USB computer connection. When connected to your Mac or PC, the plug-and-play connection empowers you to mix in audio in from music-player software and record your sets into virtually any audio recording application.
