Hercules intros wireless mixing mini-controller

Hercules has released the Mobile DJ MP3, a device it calls the world's "first wireless digital mixing mini-controller." Intended for novice DJs, the Mobile lets people pick tracks while away from their computer, and has controls for pitch, crossfading, effects, loops and over 25 other options. There are two jogwheels for scrolling and scratching, which are matched by two independent volume sliders. Should a DJ fail to pick tracks in time, the Mobile can be set to automatically pick a follow-up of its own.

Configuring the mixer involves plugging a USB radio receiver into a PC, and installing software from a provided CD. Tracks must be in CD, MP3, WAV or WMA format, and computers must be running Windows XP SP2 or better. The Mobile is on sale for $100.
