Numark has revealed their second iPod-DJ product, the iDJ2. It is much superior than its predecessor since it doesn't need two iPods for playing two channels but one instead. Beyond this, you can tempo adjust, scratch and loop both channels with its proprietary controls. It handles external USB hard disks - we hope it can play songs from there directly -, and accepts phono and line level inputs as well as a dedicated microphone. The color display is very nice and the QWERTY keyboard which is optional enhances the mixer's usability even much further. I have to mention the 3-band EQ on the channels, and an also important factor is direct playing all the protected iTunes content downloaded - but without any manipulation. iDj2's price will be 600 USD - here is the official page, enjoy.
