Ecler NUO 4.0F 4-Channel Analog Mixer - Black
The Ecler NUO 4.0F is a 4 channel analogue mixer addressed to the professional DJ that includes two analog VCF filters, offering DJs expanded creative control across all styles of club-oriented electronic music. It also supports the ETERNAL magnetic crossfader.
To mark its 60th anniversary and celebrate 20 years of the iconic NUO series (2005–2025), Ecler introduces the NUO 4.0F - a professional analog DJ mixer that fuses the brand’s legacy sound with forward-thinking features tailored for today’s most demanding DJs.
The NUO 4.0F includes two analog VCF filters with variable resonance, assignable to any channel - including the effects return - offering DJs expanded creative control across all styles of club-oriented electronic music. In response to the growing popularity of back-to-back DJ sets, the NUO4.0F features two fully independent PFL systems, 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 customisation options. It also supports the ETERNAL magnetic crossfader.
Available in two finishes - black and silver - the NUO4.0F’s exterior design reflects its premium internal architecture, crafted by Domingo Mele, the legendary engineer behind many of Ecler’s iconic mixers. Proudly made in Barcelona, the NUO4.0F is both a tribute to timeless engineering and a tool for future generations. With the NUO4.0F, Ecler celebrates six decades of audio innovation and two decades of one of its most beloved product lines. Built to last. Made to inspire.
