The iDJ2 gets a review at CNET
Numark iDJ2 Mixing Console for iPod
The good: The Numark iDJ2 provides a professional, one-stop solution for DJing with an iPod MP3 player or USB drive. Features such as XLR output, video output, a built-in color screen, and multiple pitch-control modes can't be found in comparable products at this price.
The bad: The Numark iDJ2's plastic construction doesn't inspire confidence, there's no support for protected-AAC files, and there are no built-in effects.
The bottom line: Rockstar DJs may sneer at the Numark iDJ2's simplicity and iPod novelty, but work-a-day event DJs will appreciate the system's efficiency, keyboard search, sound quality, and portability.
Numark's iDJ2 all-in-one magic box
When Numark unveiled the first iDJ iPod mixer in 2005, the half-baked product required two iPods, and lacked many essential features. After three years back at the drawing board, Numark's iDJ2 ($599 retail, $499 street) finally makes good on the promise of a professional iPod DJ mixer.
Compared with the hodgepodge of laptops, CDJ decks, mixers, and retrofitted turntables today's digital DJs are saddled with, the iDJ2's biggest selling point may be the neatness of its all-in-one system. Numark has managed to fit a two-channel mixer, music library, and DJ control surface all into a space measuring 16-inches wide by 12-inches deep by 3-inches high (including knobs).
The face of the iDJ2 is where all the fun happens. The centerpiece of the system is a slightly angled 4.25-inch color screen used to select songs and view playback status. An adjustable iPod dock above the screen uses a deep well in an attempt to keep your iPod out of harm's way. To the right and left of the screen are an identical pair of mixer controls, including knobs, buttons, faders, and jog wheels.
Like most traditional DJ mixers, all of the Numark iDJ2's audio connections are on the top edge of the console, with the exception of headphone and microphone inputs, which are conveniently located on the edge facing you. The bottom and sides of the iDJ2 are bare.
Overall, we're impressed by the iDJ2's ergonomic layout and attractive onscreen user interface, however, the all-plastic construction does feel flimsy compared to traditional analog DJ mixers.
