The Pioneer DJM-900NXS2 Professional DJ Mixer builds upon the legacy of its predecessor, the DJM-900 nexus, by incorporating enhanced FX and incorporating new high-quality audio components. Housed within a robust casing, this mixer boasts a cutting-edge 64-bit mixing processor, elevating the sound quality to a more natural and meticulous level. Complementing this advancement is a top-notch 24-bit/96kHz soundcard, direct digital connection, and improved analogue input.

The unit's controls have undergone refinement, becoming even more responsive due to a revamped gain structure, improved EQ and fader curves, a more precise clip indicator, and an enhanced peak limiter. The DJM-900NXS2 MK2 offers expanded capabilities for sound and effects management, featuring 14 Beat FX, including the innovative Vinyl Brake, Pitch, Helix, and Ping Pong, along with enhanced Reverb. The FX Frequency enables the application of frequency ranges to effects, a larger X-Pad with an OLED screen for simplified viewing, and a channel selection LED for instant identification of applied Beat FX on each channel.

In the realm of 6 Sound Colour FX, a parameter knob facilitates adjustments for each effect, Gate/Comp has been replaced by Sweep, and larger knobs enable more precise and personalized modifications. The addition of an autonomous Send/Return provides flexibility, eliminating the need to choose between Beat FX and External FX. Instead, an external FX controller (e.g., apps on an iPad) can be connected, layering it atop the on-board FX.

Noteworthy features include two USB ports, four phono inputs, a top-loaded input switcher, ProDJ Link for connecting four players and utilizing only one source, gold-plated RCAs, two headphone plugs (¼-inch stereo jack and 3.5mm MiniPin), Magvel fader, and DVS support allowing Rekordbox DJ DVS to be controlled via turntables or players using Rekordbox performance software.
