Numark DM950USB 2-Channel 8" DJ Mixer with USB

You can also record and playback your mix at the same time (full duplex). Allows you to transfer files to and from your computer, so you can mix your computer's music files with vinyl, CDs, DVDs, or vocals; or use the USB ports to get MP3, WMA, WAV, and other digital files from any USB-equipped PC or Mac in the mix.
