Numark NS4FX DJ kontroler

Numark NS4FX 4-Channel DJ Controller

The Numark NS4FX 4-channel DJ controller gives working DJs hands-on control over four software decks, with the I/O and audio quality needed for clubs, events, and livestreams. Built around a 24-bit audio interface and balanced XLR main outputs, this unit targets mobile and event DJs who need professional connectivity without flagship pricing. The hardware includes 152 mm capacitive-touch jog wheels, 16 performance pads, and dedicated loop sections. The NS4FX ships with Serato DJ Lite and is fully mapped for Serato DJ Pro. Compatibility also extends to Virtual DJ and Algoriddim djay Pro AI.

What Sets This Controller Apart

Unlike most controllers in its price tier, the NS4FX ships with balanced XLR main outputs and a separate RCA booth output with its own level control, making it directly usable in club and mobile rigs. Two independent 1/4" microphone inputs feed the USB mix, so livestreamers can broadcast a full mix with mic audio without an external sound card.

Decks, Pads, and Pitch Control

With 152 mm capacitive-touch jog wheels and a multicolor center display showing track position, BPM, pitch range, and time, the deck section enables precision scratching. Each deck hosts 8 performance pads with selectable modes for hands-on triggering.

• Jog Wheels: 152 mm capacitive-touch with multicolor display
• With Cue, Auto Loop, Fader Cuts, and Sampler modes available in Serato DJ Lite, the 16 performance pads (8 per deck) offer creative options that expand even further in Serato DJ Pro.
• Pitch Control: long pitch faders with pitch bend buttons — precise tempo matching for long blends

Four-Channel Mixer and EQ Control

Each of the four independent channels comes equipped with its own volume fader, a 3-band EQ with full kill, and a large high-pass/low-pass Filter knob. Crossfader assignment switches route each channel to side A, side B, or bypass the crossfader entirely.

• Channels: 4 independent with Layer buttons — four-deck control from two hardware decks
• For creative mixing, the 3-band EQ with full kill and HPF/LPF per channel provides full tonal sculpting on every deck.
• Crossfader: assignable A/B/bypass per channel — flexible routing for layered mixes and scratch cuts

Audio Quality and I/O

The audio interface runs at 24-bit/44.1 kHz, with balanced XLR main outputs feeding the front-of-house signal and an RCA booth output driving a separate monitor. Two 1/4" TS microphone inputs have volume and tone controls.

• Audio Quality: 24-bit / 44.1 kHz — clean, high-headroom signal
• Main Outputs: 2 balanced XLR + RCA booth — club-ready PA connectivity for front-of-house and monitor speakers
• The microphone section features 2 × 1/4" TS inputs with tone control, and Mic 1 can be switched to an RCA Aux source for added flexibility.

Who This Controller Is Built For

The Numark NS4FX is the right choice for intermediate and working DJs who want a true four-deck Serato controller with club-grade I/O at a mid-range price. Mobile and event DJs benefit from balanced XLR outputs, a dedicated booth output, and dual mic inputs that don't steal channels from the music mix. Livestreamers get a major advantage from mic-over-USB routing, which sends both mics and the main mix to streaming software without extra hardware.

Numark NS Series Heritage

Continuing Numark's NS controller line that began with the motorised-platter NS7 and expanded through the static-platter NS6 and NS6II, this model carries forward a lineage of workhorse units for working DJs. This version shifts toward a lighter form factor while keeping the pro connectivity that defined the series.
