Numark NS4FX

Professional 2-deck DJ controller with 4 channels. The perfect solution for mobile and event DJs, as well as club jocks and livestreaming mix masters. It features 44.1 kHz / 24-bit audio resolution and comes with Serato DJ Lite software for up to 2 channels, with an option to upgrade to Serato DJ Pro.

The controller includes 4 independent stereo channels, each with a volume fader, 3-band EQ, and high/low-pass filter controls. There is an FX section with 6 quick-start software effects and paddle toggle switches. Each deck has a 6-inch touch-sensitive jog wheel with a multi-color LED display to show track position, BPM, pitch range, and duration.

The loop section includes multipliers on each deck and a beat division function. A layer button allows for quick switching between deck channels—channels 1 and 3 on deck 1 and channels 2 and 4 on deck 2. Each deck features a long pitch slider with pitch-bend buttons and a selectable range for precise tempo control.

There are 8 performance pads per deck with selectable modes, including Cue, Auto Loop, Fader Cues, and Sampler (additional modes unlocked with Serato DJ Pro software). The crossfader can be assigned on side A or B for each channel and can be bypassed.

Outputs include Main (2x XLR), Booth (2x RCA, L/R), and 2 headphone outputs (3.5 mm and 6.35 mm stereo jack). There are 2 input channels: Mic/Line, switchable (6.35 mm jack or 2 RCA connectors L/R) and Mic (6.35 mm jack).
