NUO4.0F
To mark its 60th anniversary and celebrate 20 years of the iconic NUO series (2005–2025), Ecler introduces the NUO4.0F, a professional analog DJ mixer that fuses the brand's legacy sound with forward-thinking features tailored for today's most demanding DJs. This 4 channel analogue mixer is addressed to the professional DJ and includes two analog VCF filters, offering expanded creative control across all styles of club-oriented electronic music. Crafted by Domingo Mele, the legendary engineer behind many of Ecler's iconic mixers, and proudly made in Barcelona, the NUO4.0F is both a tribute to timeless engineering and a tool for future generations.

Filtering and Sound Shaping
The NUO4.0F includes two analog VCF filters with variable resonance, assignable to any channel, including the effects return, giving DJs expanded creative control across all styles of club-oriented electronic music. The mixer also features an FX Send control with a pre/post fader selector per channel, an FX Return control with PFL, and a Master insert on 6.3mm Jacks, allowing DJs to integrate outboard processing into their sets with precision.
Built for Back-to-Back and Turntablism
In response to the growing popularity of back-to-back DJ sets, the NUO4.0F features two fully independent PFL headphone systems, specially designed for B2B performance, enabling two DJs to pre-listen to any channel simultaneously with split mode functionality for precise cueing. Designed with turntablism and advanced scratching techniques in mind, it offers extensive fader and crossfader customization, including 60mm Ecler faders with fading curve control and support for the Ecler ETERNAL magnetic crossfader.
Build, Connectivity, and Finish
The NUO4.0F offers 4 mixing channels with 4 PHONO/LINE inputs plus 1 AUX input, a MICRO input on an XLR/Jack combo connector, and Master/Booth outputs on XLR and RCA connectors. It delivers a maximum output without distortion of 21dBV (23dBu). Available in two finishes, black and silver, its exterior design reflects its premium internal architecture. Built to last, made to inspire.
