The djm-250mk2 has inherited some of the professional features of the popular DJM-900NXS2, such as the Marvel crossfader and sound color FX filter. Straightforward controls, a clear layout, and dedicated 3-band isolators let you scratch and mix instinctively. The dithering technology on this mixer results in warm, high-quality audio from both analogue and digital sources. Plus its built-in sound card lets you connect the mixer to your PC/Mac and use rekordbox DJ to perform with CDJs. Or hook up the djm-250mk2 to turntables and use rekordbox DVS in combination with our control vinyl to scratch and mix with digital files stored on your computer.
