The Numark NS4FX is a four-channel DJ controller designed for Serato DJ Lite and Serato DJ Pro. It combines four independent mixer channels, 6-inch jog wheels with colour displays, performance pads, paddle-style effects controls and professional XLR outputs in a relatively compact unit.
It is aimed at DJs who want genuine four-deck control without moving to a much larger flagship controller, making it especially relevant for mobile, event and livestreaming setups.

Four-channel mixing
The NS4FX provides four physical mixer channels, each with its own volume fader, three-band EQ and high-pass/low-pass Filter control. This means all four software decks can remain visible and independently mixed rather than relying on a simple two-channel layer system.
Front-panel crossfader assignment switches let each channel be routed to either side of the crossfader or bypass it completely.
6-inch jog wheels with displays
The two 6-inch capacitive jog wheels include colour displays that show track position, BPM, pitch range and time information. Deck Layer buttons switch each physical side between its two software decks.
Performance pads
Eight performance pads on each deck provide direct access to functions such as Cue, Auto Loop, Fader Cuts and Sampler. Additional modes become available when upgrading to Serato DJ Pro.
Effects paddles
The effects section includes six quick-selection buttons, wet/dry and beat-division controls, plus two paddle-style switches for momentary or latched triggering. This makes effects easier to perform rhythmically than relying entirely on software controls.
Professional connections
Balanced XLR main outputs are joined by a separate RCA booth output, giving the NS4FX enough connectivity for mobile DJ work and event systems. Two microphone inputs are provided, and the rear microphone connection can also be switched to an auxiliary RCA source.
Microphone audio is included in the USB mix, which is useful for livestreaming because voice and music can be captured together without an additional interface.
Serato DJ Lite and Pro
The NS4FX ships with Serato DJ Lite and is fully mapped for Serato DJ Pro. The Pro upgrade unlocks the fuller four-deck performance feature set and additional pad modes.
Numark also lists compatibility with VirtualDJ and Algoriddim djay.
