The DDJ-400's buttons and knobs are arranged in the same way as those on our professional NXS2 set-up. Develop your skills using an interface similar to that of our club-standard player, and enhance your mixes with Sound Color FX and Beat FX featuring curves taken from our DJM-900NXS2 mixer. You'll soon feel comfortable performing in DJ booths.
