Behringer CMD Studio 4A DJ Controller
The CMD Studio 4A provides all the tools needed to learn the basics of DJing - or to work the dance floor into a virtual frenzy. This is no crippled budget controller; Studio 4A has the very same features you'll find on the bigger, more expensive controllers. And the Studio 4A not only includes those features - it actually improves on them.
Behringer built a 4-out USB sound card into the Studio 4A, so you're ready to go right-out-of-the-box. This high-quality audio interface has 24 bit converters and provides ultra-low latency operation in either Windows or OS X.
Most DJ software is capable of running 4 or more virtual decks, so the Studio 4A can control up to 4 virtual decks. The same goes for other features, like library navigation, looping controls, EQ kills, keylock, and much more.
