Ecler NUO4.0F 4-Channel Analog DJ Mixer - Black

Ecler NUO4.0F 4-Channel Analog DJ Mixer

The Ecler NUO4.0F 4-Channel Analog DJ Mixer combines four phono/line channels, dual assignable VCF filters, independent cue systems, and adjustable fader controls for professional club mixing. Available in black or silver, it supports turntables, digital players, microphones, external effects, back-to-back sets, and advanced scratch techniques.

Each channel provides gain control, three-band full-cut equalization, effects-send adjustment, pre/post-fader routing, and flexible crossfader assignment. Two voltage-controlled filters offer selectable high-pass or low-pass operation, variable frequency, and adjustable resonance. DJs can route either filter to any input channel or the effects return for transitions, frequency sweeps, and tonal shaping.

Two independent PFL systems let separate performers cue channels through dedicated headphone connections, making the mixer especially useful for back-to-back DJ performances. Balanced XLR and unbalanced RCA master and booth outputs support club systems, mobile rigs, and studios. The NUO4.0F is manufactured in Barcelona and accepts the optional Ecler ETERNAL magnetic crossfader.

Key Features

• Black and Silver Variants: Choose between two finishes with the same professional mixing features and connection layout.
• Four-Channel Analog Mixing: Connect four phono sources, four primary line sources, an auxiliary source, and a microphone.
• Dual VCF Filters: Assign two high-pass or low-pass filters to any channel or the effects return.
• Independent DJ Monitoring: Two separate PFL systems allow two performers to cue sources simultaneously during back-to-back sets.
• Flexible Effects Routing: Send each channel to external processing before or after its channel fader.
• Adjustable Fader Response: Shape the response of the 2.4-inch channel faders for gradual blends or faster cuts.
• Scratch-Oriented Crossfader Controls: Adjust the curve, reverse the assignments, and configure the cut-in point for performance techniques.
• Professional Output Section: Balanced and unbalanced master and booth outputs integrate with club, studio, and mobile sound systems.
