4 deck Serato DJ controller. Aside from cool look and those great 4.3-inch full-color screens, the NVII adds gridlines on the screens so you can seamlessly beat match your tracks. In addition, the NVII adds a 5-column sort to view your music—3 columns at time—by song, artist, time, bpm and key. We didn’t just improve an already great DJ controller—we created the NVII to reiNVigorate your DJ skills! Manipulate up to six simultaneous FX on each channel including the master channel. FX controls are capacitive, delivering jaw-dropping capabilities with a simple touch, twist, or both.
