The Numark 4TRAK 4-Channel Traktor Controller:

Four decks of software control, a four-channel mixer and total command over all effects: Meet 4TRAK, the ultimate controller for Traktor DJ software. 4TRAK lays out a vast assembly of tactile controls in front of you, putting a playground of capability at your fingertips. Mix anything: 4TRAK's built-in four-channel mixer allows you to bring turntables, microphones, MP3 players and more into the mix. Tweak everything: high-resolution platters, exclusive Strip Search needle-drop technology and an expansive 12-knob FX KOMMAND CONSOLE give you more precise control over Traktor than ever before.

At the heart of 4TRAK is a premium-quality fully independent four-channel mixer that can be used with or without a computer, making 4TRAK one of the most versatile Traktor controllers in the world. 4TRAK has a full range of input and outputs for connecting virtually any device: RCA inputs on each channel and four line-level inputs with two switchable to phono and two switchable to mic. Connect almost any external music source like turntables, CD players and microphones, and mix them in seamlessly with tracks from your software.

4TRAK offers unparalleled control over your effects and filters. With the FX KOMMAND CONSOLE, you have top-level access to effect and filter parameters, giving you incredible performance capabilities. Layer effects, adjust filters, and mix and match both of them in ways that were previously impossible.

4TRAK's FX KOMMAND CONSOLE gives you two decks of effects controls, FX1 and FX2, plus four detented filter knobs for each of 4TRAK's four channels. Both the FX1 and FX2 decks give you three controls that can be assigned to the effects of your choice. Each FX deck also features time division controls, allowing you to match your effects to a track's BPM instantly, and giving you continuous control over an effect's pacing.
