Experience DJ mixing in its most musical form with the AlphaTheta euphonia Professional 4-Channel Rotary Mixer.
Designed for DJs who value warmth, depth, control and feel, the euphonia brings together high-resolution digital technology and analogue-style sonic character in a premium 4-channel rotary mixer. It has been created for expressive mixing, long blends, deep transitions and high-quality sound systems where every detail matters.
At the heart of the euphonia is a specially tuned transformer circuit co-designed by AlphaTheta and Rupert Neve Designs. This circuit adds musical harmonics to the sound, helping create a rich, smooth and energetic tone that feels natural to mix with. Low frequencies sound stable and punchy, mids feel present and expressive, and highs remain smooth and refined.
The result is a mixer that bridges the gap between modern digital clarity and the warmth associated with classic analogue mixing desks.
Euphoric Sound with Rupert Neve Designs
The euphonia is built around a unique sound character.
All audio passing through the mixer is processed through a transformer circuit co-designed with Rupert Neve Designs, known worldwide for legendary analogue studio equipment and mixing consoles. This gives the euphonia a rich and musical character that helps different tracks blend together naturally.
It is especially well suited to:
- House
- Disco
- Soulful electronic music
- Deep house
- Techno
- Balearic
- Garage
- Vinyl-focused sets
- Long, smooth blends
- Hi-fi listening environments
Digital Clarity with Analogue Richness
The euphonia uses high-quality 32-bit A/D and D/A converters and 96kHz/64-bit floating point mixing processing to reproduce music with detail and accuracy.
This gives DJs the benefit of modern digital precision while maintaining a warm and musical sound character through its analogue transformer circuit.
The result is a mixer that sounds polished, open and powerful across professional club systems, hi-fi setups, studio monitors and high-end home DJ systems.
Smooth Rotary Mixing Experience
Unlike a traditional line-fader mixer, the euphonia uses premium rotary controls for each channel.
This encourages a smoother, more musical style of mixing, making it ideal for DJs who enjoy gradual transitions, careful layering and expressive volume control. The rotary feel is designed to give DJs a deeper physical connection with the mix.
The layout is clean, elegant and performance-focused, helping you concentrate on the music rather than overcomplicated controls.
4-Channel Professional Layout
With four channels, the euphonia gives DJs the flexibility to connect a full professional setup.
It is ideal for use with:
- CDJ-3000 players
- CDJ-3000X players
- Turntables
- rekordbox setups
- Serato DJ Pro setups
- Vinyl and digital hybrid systems
- External effects units
- Studio and listening room setups
This makes it a strong choice for clubs, audiophile bars, listening venues, home studios and DJs who want a premium rotary mixer with modern connectivity.
Master Isolator and Creative FX Control
The euphonia includes performance features designed for creative mixing while keeping the sound natural and musical.
The master isolator gives DJs broad control over the overall frequency balance, allowing dramatic but smooth transitions. Built-in Send FX and send/return options also give you creative flexibility for echo, delay, reverb and external effects routing.
These tools make the euphonia more than a traditional rotary mixer — it is a modern performance mixer built around musical expression.
