Numark NS4FX Review: The Cheapest 4-Channel DJ Controller

The Numark NS4FX takes entry-level DJ controllers into new territory, bringing 4-channel mixing to sub-$500 setups for the first time. Designed to bridge the gap between basic and professional gear, it allows aspiring DJs to experiment with multi-layer mixes at bargain pricing.

Unboxing and Setup

The NS4FX includes:

• The controller itself
• USB connection and power adapter
• Compatible with Serato DJ Lite (free) and Pro (paid), plus Virtual DJ and Algoriddim DJ

All four channels are available to use out of the box with Serato DJ Lite, a major advantage over many rivals.

Hardware Features

Despite a budget build, the NS4FX delivers:

• Touch-sensitive jog wheels with center BPM displays
• Dedicated play, cue, sync, and layer control buttons per deck
• Full-size pitch faders for smooth beat matching
• RGB performance pads offering cues, loops, and sampler modes

The layer system allows users to control four decks from two physical platters, switching between layers to manipulate independent tracks.

Mixer Section and Outputs

Packed with pro-grade functionality:

• 4-channel mixing section with upfaders, crossfader, and EQs
• Professional outputs (XLR, RCA) for club setups
• Multiple mic and aux inputs for vocal and instrument integration

The NS4FX’s outputs outclass similarly priced competitors, especially for DJs who plan to take their controller to live events or clubs.

Performance and Software Upgrades

Upgrading from Serato Lite to Pro unlocks:

• Four-deck waveform view
• Advanced FX banks and pad modes
• On-controller recording and more

Stream music from Beatport, Beatsource, Tidal, and SoundCloud GO+ with subscription support. Layer control ensures seamless mixing across all four virtual decks.

Market Comparison

Compared to its closest competitor, Pioneer’s DDJ-FLX6, the NS4FX is $100 cheaper and provides more professional output options.
While the DDJ-FLX6 supports Rekordbox (not available on NS4FX), the Numark model is better mapped for Serato and live sound setup.

Note that the NS4FX does require external power, not just USB—a minor trade-off for stronger sound and more pro features.

Pros and Cons

Pros	Cons
Four full-featured channels	Must pay for Serato Pro to unlock all features
Professional-grade outputs	Requires external power (not USB only)
Excellent jog wheel displays	Layer system can be confusing for new users
Solid software compatibility	Only two physical decks; rest are layers

Final Verdict

The Numark NS4FX is the most affordable way to get true four-channel control for beginners and advanced DJs looking to expand. Its superior outputs and feature set make it a killer value—especially for those ready to gig or experiment with complex sets.
