Digital clarity with analogue warmth

The Euphonia combines high-resolution 32-bit A/D and D/A conversion with 96 kHz / 64-bit floating point DSP processing to deliver highly detailed, accurate sound reproduction. Every signal passes through a custom transformer circuit developed alongside Rupert Neve Designs, adding harmonics and analogue-style richness for a smoother, more energetic sound.

Expressive rotary mixing

Specially developed rotary faders provide an intuitive and tactile mixing experience with variable resistance depending on rotation speed. Fine adjustments feel controlled and precise, while faster movements remain fluid and responsive, allowing DJs to focus on musical expression and long-form blends.

Optimised for smooth transitions

The rotary volume curves have been refined with input from professional DJs to enable natural, seamless transitions without relying heavily on EQ adjustments. This creates a more musical workflow focused around volume blending and tonal balance.

Energy Visualizer monitoring

The Euphonia features a uniquely designed Energy Visualizer system including individual channel needle meters and a master Spectrum Analyzer. DJs can monitor channel balance and overall mix energy at a glance, helping maintain smooth, controlled mixes throughout long performances.

Built-in spatial effects

Six built-in effects including Delay, Tape Echo, Echo Verb, Reverb, Shimmer, and High-Pass Filter add depth and movement to performances. Dedicated send controls on each channel allow precise effect application, while the intelligent time control system switches between BPM-clicked and smooth free adjustment depending on the selected effect.

External FX integration

A dedicated Send/Return section enables connection of external effects processors and hardware for expanded creative workflows and customised performance setups.
