The Pioneer DDJ-SZ is a premium professional four deck DJ controller and interface for Serato. Top-of-the-line build quality and copious attention to detail is evident throughout, from the metering displays inside of the high resolution jog wheels to feel of the RGB-lit, velocity-sensitive pad banks for triggering samples and cue points. Dedicated controls for all of Serato's critical functions are onboard, plus the mixer can operate independently, with dedicated filters, EQ and faders for CDJs, turntables and other analog sources. If you're in need of a one piece best-in-class DJ tool for working with Serato, look no further.
