Numark NS4FX

A four-channel Serato controller with XLR and booth outputs at a mid-range price; the mics and crossfader let it down.

The Internet’s Opinion

From 11 professional reviews and 14 owner reviews: a fair amount of evidence.

Nine of eleven professional reviews recommend it for four channels, XLR and booth outputs and two mic inputs at a mid-range price; the two mixed reviews call it mostly plastic and say it only makes sense with a paid Serato DJ Pro upgrade. Guitar Center owners are split: they repeat the praise for value and portability, but several report distorted mic inputs and laggy scratching.

What people praise

  • A lot of controller for the money
  • Four channels with XLR main, booth output, two mic inputs and an aux input
  • Light and compact enough to carry to gigs
Show 4 more
  • Jog wheel displays show BPM, time and pitch, so you look at the laptop less
  • Paddle effects are quick and easy to use
  • Loud, clean 24-bit output
  • Mic and aux audio go down the USB cable, so livestreams need no extra interface

What to know first

  • Ships with Serato DJ Lite; the full feature set needs a paid Serato DJ Pro upgrade
  • Scratching feels laggy or indirect; not one for scratch DJs
  • Microphone inputs distort or sound poor
Show 5 more
  • Crossfader feels cheap or flimsy
  • Mostly plastic, and feels less solid than pricier controllers
  • Pitch faders sit too close to the jog wheels
  • Weak metering: master level only, no per-channel or cue levels
  • Performance pads light white only, not RGB

You’ll also need

  • A computer running DJ softwareNot standalone

    The NS4FX is not a standalone mixer: a computer running DJ software such as Serato DJ Lite is needed for playback from its four decks Manufacturer spec sheet (Numark), checked 2026-10-11

  • Speakers and cablesNot in the box

    The box holds the controller, power adapter, USB cable, software download card and paperwork; speakers or an amplifier and the XLR or RCA cables to reach them are sold separately Manufacturer spec sheet (Numark), checked 2026-10-11

  • HeadphonesNot in the box

    Headphones are not included; the controller has both 1/4" (6.35 mm) and 1/8" (3.5 mm) headphone outputs Manufacturer spec sheet (Numark), checked 2026-10-11

  • A mic cable with a 1/4" jackNo XLR mic inputs

    Both microphone inputs are 1/4" (6.35 mm) TS jacks, not XLR, so a standard XLR microphone needs an XLR-to-1/4" cable Manufacturer spec sheet (Numark), checked 2026-10-11

Our take

Rory TassellWritten from the sources on this page, not from a loan unit.

Nine of eleven professional reviews recommend it for four channels, XLR and booth outputs and two mic inputs at a mid-range price. The reservations repeat: seven reviews note it ships with Serato DJ Lite and needs a paid Pro upgrade, six reviewers and owners found scratching laggy, and five report distorted mic inputs. Buy it for four-channel mixing at events, with mics run through a separate mixer; scratch DJs should look elsewhere.

What it is

Status, October 2026: current. Numark still lists it among its DJ controllers.

What it is

The NS4FX is a four-channel DJ controller from Numark, launched in April 2022 (Numark product page). It is not standalone: a computer running DJ software plays the tracks. It ships with Serato DJ Lite, is fully mapped for Serato DJ Pro as a paid upgrade, and also works with VirtualDJ, which needs a Pro Infinity or Pro Subscription licence, and Algoriddim's djay on Mac, iOS and Windows.

Each of the four channels has a volume fader, a three-band EQ with full kill, a high-pass/low-pass filter knob and a crossfader assignment switch for side A, side B or bypass. The two hardware decks have 6-inch capacitive touch jog wheels with a colour display showing track position, BPM, pitch range and time, and a Layer button switches each deck between two software decks. Each deck also has eight performance pads with Cue, Auto Loop, Fader Cuts and Sampler modes, a long pitch fader with pitch bend buttons and a loop section. The FX section has six effect buttons, two paddle switches and wet/dry and beat controls.

The 24-bit, 44.1 kHz audio interface has two balanced XLR main outputs, an RCA booth output with its own level, and 1/4" and 3.5 mm headphone jacks. There are two 1/4" TS mic inputs with volume and tone, one on the front and one on the rear that switches to an RCA aux input. The main mix, the aux input and both mics also go to the computer over USB, so a livestream can carry the voice without a separate interface.

It runs on the included 12 V, 2 A power adapter, measures 597 x 274 x 61 mm and weighs 3 kg. The box holds the controller, the power adapter, a USB cable, a software download card and the paperwork.
