Ecler NUO 4.0F - 4 Channel Analog Mixer in Silver

The Ecler NUO 4.0F is a professional 4 channel analogue DJ mixer designed for club installs, studio setups and touring DJs who demand precise sound and creative control. With dual analogue VCF filters, flexible routing and rock solid audio performance, it gives you the tools to shape your mix with confidence across any style of electronic music.

Each of the four channels offers switchable phono and line inputs, with an additional AUX and dedicated microphone input to cover turntables, media players, laptops and mics. High headroom outputs, low distortion circuitry and detailed 3 band EQ ensure your sets sound clean, powerful and controlled, whether you are playing in a small booth or a large club system.

Built around Ecler's renowned analogue architecture, the NUO 4.0F delivers a wide frequency response and excellent signal to noise performance. The result is a transparent, musical sound that responds naturally to EQ moves, filter sweeps and effects sends, making it ideal for DJs who like to work the mixer as an instrument.

With two independent headphone PFL sections for back to back sets, a dedicated FX send and return, and support for the ETERNAL magnetic crossfader, the NUO 4.0F is ready for demanding professional use. Whether you are mixing long, subtle blends or cutting aggressively between tracks, it keeps your workflow fast, intuitive and reliable.

Analogue Sound and Precision EQ

The NUO 4.0F's fully analogue signal path is engineered for clarity and warmth, with a frequency response extending well beyond the audible range. Each channel features a 3 band EQ with generous cut and boost, allowing you to sculpt bass, mids and highs with precision. From tight, punchy low end control to smooth top end shaping, the EQ section helps your tracks sit together perfectly in the mix.

Dual VCF Filters for Creative Mixing

Two independent HP/LP VCF filters with variable resonance put powerful sound design tools at your fingertips. Sweep from deep low pass to biting high pass, then dial in resonance to taste for anything from subtle movement to dramatic filter drops. With a wide frequency range, these filters are ideal for building tension, reshaping loops and adding character to transitions.

Flexible Routing and Connectivity

With four phono/line capable channels, an AUX input, dedicated microphone input and comprehensive output options on both XLR and RCA, the NUO 4.0F integrates easily into a wide range of setups. Separate master and booth outputs, a record out, FX send and return, and a master insert on 6.3 mm jacks give you the flexibility to connect outboard processors, recording devices and monitoring systems without compromise.

Performance Focused Faders and Monitoring

60 mm Ucler channel faders with adjustable curve let you tailor the feel for smooth blends or fast cuts, and the crossfader is compatible with the ETERNAL magnetic unit for long term reliability and precise performance. Two independent headphone PFL outputs, with both 6.3 mm and 3.5 mm connections, are specially designed for back to back DJing, so two DJs can cue and prepare their mixes simultaneously.
