The Pioneer DJ DJM-S11 is a professional 2-Channel, 4-deck, battle mixer that boasts brand new features and offers improved functionality that expands performance capability when used with Serato DJ Pro or rekordbox. The mixer now has a 4.3-inch touch screen that displays all the information you would need at a glance, including track info, playback positions, waveforms and browsing functionality. There is even the ability to move your finger across the Touch FX screen to modify the texture of the music and use Touch MIDI to initiate functions within the DJ software. To entice an excellent crowd reaction or battle placement, the DJMS11 allows up to four tracks to be played simultaneously using the world’s first Deck 3/4 Control. On the touch screen, the added decks are displayed along with a range of controls which allows the browsing of tracks, loading of tracks, setting loops, triggering Hot Cues, modifying EQs and more. With Serato DJ Pro you can go one step further and use Deck Mover to move tracks from deck 1 to 4 and deck 2 to 3 without even having to break the music. This is an excellent feature for freeing up the main decks in preparation for subsequent tracks. When Dual Deck control is turned on it allows one fader, knob or control to operate tracks in decks 1 and 3 or 2 and 4; splendid for scratching two decks at once, adjusting the volume or adding effects.
