Beyond The Decks: a new format by Woodbrass
With Beyond The Decks, we’re launching a format designed by and for DJ gear enthusiasts. The goal? To spotlight equipment that marks a real turning point in the pro DJ world, alongside those who truly use it.
For this first episode, we head to Hometown in Nantes, a warm and audiophile venue where we meet Guillaume Combeuil. Founder of Combeuil Audio, resident DJ at club Macadam and a sound system expert, he shares his vision of the AlphaTheta Euphonia.
A rotary mixer… but unlike any other
From the very first moments, the Euphonia grabs your attention. Its sleek design, robust rotary potentiometers, and unique sonic signature make it a standout in the jungle of DJ mixers.
Far from classic analog rotary mixers, the Euphonia is a fully digital mixer but with an astonishingly natural mechanical feel:
- At slow movement, the knobs are firm, perfect for smooth transitions.
- At fast movement, they become more flexible, allowing for sharp and dynamic cuts.
This dual mechanical response offers unprecedented versatility, suitable for both smooth and highly rhythmic sets.
Digital serving analog warmth

What truly makes the Euphonia unique is its analog output section developed in collaboration with the audio experts at Rupert Neve Designs. For those unfamiliar: this name is a benchmark in the world of high-end studio consoles.
The result? A warm, harmonic, and detailed character you feel from the very first minutes of use.
“Don’t hesitate to push the gain a bit to really make the transformer work,” Guillaume tells us.
So it’s a mixer you listen to, but above all one that expresses itself depending on your mixing style.
Features designed for DJs
On the features side, the Euphonia ticks all the boxes… and then some.
Customizable isolator
The three-band isolator can be configured for a boost of +12 dB, +6 dB, or neutral, depending on your style and caution level.
Advanced effects unit
Inspired by the built-in effects of Pioneer DJM mixers, it goes further by allowing:
- Sending effects to a specific frequency band (bass, mid, treble, or combination),
- Applying them to one or multiple channels via the Send button,
- Integrating an external effect through the classic Send/Return loop.
By combining internal effects with your external gear, you can create a true sonic identity in your mix.
A visual interface as vintage as it is practical
It’s hard to miss the four needle VU meters on top. Besides adding a stylish retro look, they provide ultra-precise visual control channel by channel.
Add to that an integrated spectrum analyzer, and you can:
- Visualize the frequency distribution even before playing a track,
- Anticipate differences in mastering or audio quality,
- Know how far you can “push” the mixer without saturating.
This is especially useful when switching between old-school vinyl and over-mastered digital tracks.
Connectivity ready for all setups
The Euphonia is not exclusive. It adapts to all styles and configurations:
- 4 line inputs,
- 4 phono inputs for vinyl,
- 4 SPDIF digital inputs,
- Master and Booth outputs,
- USB port for DJ software with timecode,
- And a Send/Return loop to expand your sonic palette.
No matter your workflow, you can integrate it without constraints.
A mixer that crosses style boundaries
Traditionally, rotary mixers appeal to house, disco, or minimal scenes. But the Euphonia breaks the mold.
Guillaume confirms it to us:
“For the first time, techno artists like Hector Oaks or Patrick Mason are asking me for it.”
Why this change?
Because it combines the digital precision of a DJM with the organic feel of an analog mixer. You can do cuts, play with effects, and enjoy a rich, textured sound.
In short: the best of both worlds.
Who is the AlphaTheta Euphonia for?
Let’s be honest: it’s not an entry-level mixer. But if you’re looking for a complete mixing experience, it’s for you if you are:
- A seasoned DJ looking to stand out,
- A sound enthusiast wanting the very best,
- A club or venue concerned about sound quality,
- Or simply curious to try a new format.
Good news: it’s available for rent at Combeuil Audio. Perfect to try before adding it to your rider.
Conclusion: a new benchmark on the market
The AlphaTheta Euphonia redefines the standards of rotary mixers. Combining refined design, advanced digital technology, and analog warmth signed Neve, it offers a rich, precise, and inspiring mixing experience.
