Historic Mixing Meets Cutting-edge Performance Power

AlphaTheta’s Euphonia distills these decades of hallmark designs and turntable history into a 4-channel rotary mixer that has Sweetwater’s DJs inspired and delighted by AlphaTheta’s unwavering craftsmanship, merging heritage interfacing with state-of-the-art 32-bit A/D and D/A converters, next-gen rotary faders, and a cutting-edge transformer circuit co-developed with Rupert Neve Designs. Because it was custom-built and tuned for Euphonia, the RND transformer introduces a detailed veneer of shimmering harmonics and an energetic polish to give your seamless mixing even greater panache. Its comprehensive suite of per-channel equalization, a 3-band master-channel Isolator, and onboard effects are supplemented by innovative performance tools, multiple FX sends, and multimode compatibility that lets you enjoy Euphonia’s distinctive sonic character with Serato and rekordbox, in addition to classic vinyl. With an armature of output options and contemporary, reactive tactility, AlphaTheta’s Euphonia is unmatched in its modular mixing capabilities — it elevates any DJ setup with an ode to the hi-fi history that started it all.

Dynamic, one-handed FX and innovative Isolator design

One of the rotary mixer’s historic staples is its isolator, and AlphaTheta honors that hallmark performance appointment by outfitting Euphonia with a masterclass in isolator design. Its 3-band design attenuates the levels of each respective register, allowing you to selectively boost or cut the frequency band of the entire output to provide an additional dimension of mixing possibilities. But why stop there? Euphonia features a suite of five onboard spatialization effects — delay, tape echo, echo verb, reverb, and shimmer — that is accompanied by a highpass filter and an external option to use Send FX. When an effect is present, activating the Isolator’s “Send” button allows you to apply your effect to that band, proportionately saturating with continued clockwise rotation. Plus, you’ve got up to 12 decibels of boost available to instantly bolster the FX send, ensuring stable levels throughout your carefully concocted transition. With one-handed control for applying an effect as you adjust the Isolator band, you can conjure inventive mixing opportunities across Euphonia’s 4-channel array, thanks to that free hand.

Comprehensive interfacing to play your way

Paying homage to the earliest days of DJing, AlphaTheta has equipped Euphonia with a laundry list of comprehensive controls to guarantee complete coherence with your sonic vision. Each channel includes a Trim control, level meter, 3-band EQ, Cue designation, and Send knob, alongside a 4-point input selector that lets you mix and match Phono, Line, Digital, or computer sound sources. A dedicated 2-band EQ and Level knob provides additional control over your Booth output, while headphone playback can be toggled between standard stereo and a mono split. For DJs using in-ear monitors, this second option — known as “split cueing” — allows your cued and master output to play in mono to each respective ear. When it comes to monitoring your mix, Euphonia’s vivid display serves as a multimode source of real-time feedback, offering conventional VU-meter readings, as well as a spectral analyzer to get a granular look at your sound’s behavior. They’ve even color-coded each channel to give you a comprehensive visualization of the whole mix, illustrating how the frequency bands of each channel interact with one another.

Complete connectivity with rekordbox, Serato, and more

Between Euphonia’s onboard 32-bit A/D and D/A converters and the 96kHz/64-bit floating-point DSP that AlphaTheta’s been refining for years, no effort was spared to ensure Euphonia preserves every nuance of your tracks. Masterfully threading the needle between digital and analog, DJs of any style — new- or old-school — can utilize Euphonia’s suite of sound-shaping tools. Phono and Line input pairs are available for each channel, in addition to four digital inputs, two signal ground contacts, and a USB-C port to connect your laptop and take advantage of Euphonia’s onboard support for rekordbox and Serato if vinyl records aren’t your speed. Stereo pairs for your Master output, your Booth output, and a dedicated recording output are offered in XLR, TRS, and RCA terminals, respectively. The Recording output can be used with supplementary gear, like a power amp. Toss in the fact that Euphonia’s suite of Send FX- and Master Insert-pairs lets you incorporate virtually any external audio processing into your setup, and you can rest assured knowing that AlphaTheta’s primed Euphonia for electrifying performances.

From Studio 54 to contemporary hi-fi: a (very) brief history

During the disco deluge of the 1970s, DJing was born out of a collective desire to engage with music and the culture around it, bringing people together. Rotary mixers comprised the first commercial club mixers to emerge, populating the likes of Paradise Garage and other legendary nightlife venues, preferred for the hands-on tactility of the rotary fader’s detailed, precise control, alongside the use of components necessary for hi-fi audio preservation. When the infamous Disco Demolition Night of 1979 led to a riot during the Chicago field’s double-header between the White Sox and the Detroit Tigers, it would herald the end of disco’s reign as the preeminent force of popular music. This same period would mark a dramatic series of technological advancements that revolutionized how we write, record, and produce music, leading to a proliferation of partly or fully digital instrumentation, breaking down many boundaries around who a given instrument or tool was “for.” Disco’s demise meant that dance music would return to the underground, as burgeoning iterations of hip-hop, techno, groove, and boogie genres capitalized on the newer, cheaper tech. This influence was felt with DJs, too, as mixers traded rotary faders for the more affordable, more malleable sliders — the first domino to fall as mixing, scratching, back-queueing, and beat-juggling techniques would evolve, increasing in complexity as DJs challenged performance conventions. Decades would pass before the 2010s would see a resurgence in the popularity of rotary mixers, which have now become commonplace at clubs, listening bars, and the homes of audiophiles around the world, all of which laud the rotary mixer for its hi-fi architecture, the creative potential of the Isolator circuit, and detailed, high-resolution control that rotary faders uniquely enable. Studio 54 may be no more, but AlphaTheta’s proudly staked out their space in the rotary resurgence, propping up Euphonia as a flagship execution of the historic mixing technology that’s been with DJs and turntablists from the beginning.

Key features

Euphoric sound with digital clarity and analog richness from Rupert Neve Designs transformer

The euphonia produces a euphoric sound with the clarity of digital and the richiness of analog that’s never been heard from a DJ mixer before.
To deliver a clearer sound quality that accurately reproduces the expression of the music, the euphonia uses high-quality 32-bit A/D and D/A converters as well as 96kHz/64bit floating point mixing processing operations in the DSP, utilizing the digital signal processing technology AlphaTheta has developed over many years.

All sound coming out of the euphonia passes through a transformer circuit co-designed by AlphaTheta and Rupert Neve Designs, the legendary makers of outstanding analog audio circuitry and mixing desks revered by artists and sound engineers around the world. This transformer circuit, tuned specifically for the euphonia, adds harmonics to the music and creates a glossy and energetic sound that’s smoother for mixing. Low frequencies such as kicks and bass are more stable and punchy, mid frequencies like vocals and instruments have more presence and gloss, and high frequencies such as hi-hats sound silky and natural. The transformer breaks down the barrier between vintage live and modern electric sounds, making mixing easier and surprisingly natural, as if recordings in different styles were originally one piece of music.

Specially developed rotary fader makes you feel one with the music

When you touch the faders on the euphonia, you won’t want to let go. To enhance its intuitive mixing experience, the unit is loaded with rotary faders that feature a brand-new carefully developed design to give you the feeling that you and the mixer are one. After extensive testing, the perfect knob sizes were chosen, with an elastomer applied to the outer circumference of each to ensure a comfortable and reliable grip as well as a high level of vibration absorption.

The uniquely developed mechanism for the faders also benefits from optimum weighting. You’ll notice a difference in the feel of the knobs when you turn them at different speeds, as a smooth load is applied when you turn a knob slowly for delicate fine-tuning and a limited load level is applied when you turn a knob quickly to instantly reach your intended volume level. And the fader volume curves have been optimized through feedback from numerous DJs, enabling smooth and natural mixing without equalizing, so you can concentrate on volume control. This innovative fader allows for musical expression that will move your audience and enhance your performance.

Energy Visualizer for understanding overall sound at first glance

Get an instant visual grasp of the status of your mix and the balance of track volume levels by glancing at the euphonia’s Energy Visualizer. Conventional VU meters only have 1 needle meter, making it difficult for DJs to grasp multiple channel levels at the same time. But the euphonia’s uniquely developed Mix Level Meter features a needle meter for each channel so you can visually check the levels for all channels and mix smoothly while keeping the groove going. You can even keep an eye on the balance of the master output by looking at the Spectrum Analyzer, which helps you keep your mixes sounding consistent and smooth, even in a long set, as you “watch” the euphonia’s output and adjust it to create your perfect sound.

Next-generation 3Band Master Isolator that transforms sensibility into sound at your will

Highest-quality isolator

The size of the isolator knobs is perfect for rapid turns from center to maximum or minimum, and the torque load is perfectly balanced for both quick operation and fine sound quality adjustment, with a luxurious feel that’s not too light. The cut-off frequency and slope are set to control and highlight the kick, melody, and rhythm bands in a natural yet sharp manner.

Brand-new Boost Send for one-handed effects application

Add one of the built-in Send Effects, or an effect from an external unit, to the sound of any of the master isolator frequency bands. Press the Boost Send button for the low, mid, or high and, as you turn the isolator knob, the effect will be applied to that band. This enables you to apply effects with a single hand in a way that previously needed two, leaving the other hand free for mixing another track.

Boost Level to help you express your style

Pick the Boost Level setting that suits your playing style and the volume level of each frequency band will be increased by the relevant amount. Choose +12dB for dynamic performances, +6dB for sound quality adjustments, and 0dB for reverb effects without any volume boost.

Built-in Send FX to bring depth and breadth to your sound

The euphonia features 5 built-in spatial effects and a high-pass filter, so you can easily add depth and breadth to your music. These are: Delay, Tape Echo, Echo Verb, Reverb, Shimmer, and HPF (high-pass filter). Also Send/Return section which you the option to connect external effects units. A dedicated knob on each channel enables you to adjust the send level going to the selected effect, so you can apply just the right amount. And the time knob, which allows you to adjust the effect delay and reverb time, has a proprietary mechanism developed specifically for this unit that automatically switches between a clicking sensation and no-clicking sensation depending on the effect you’ve selected. When using Delay, Tape Echo, and Echo Verb, the knob clicks according to the BPM, so you can quickly apply effects. When you use Reverb and Shimmer, there’s no clicking so you can turn the knob freely to perform smooth sweeps or make tiny adjustments to find the perfect setting.

Design that embodies a new era of rotary mixer

The euphonia was designed to signify a new era of rotary mixers, with a “two-tone, two-layer” look symbolizing tradition and innovation. The channel strip section, which comprises traditional mixer elements, is distinguished from the innovative display section by matte and gloss textures, resulting in a crisp design that combines analog and digital elements. The copper color of the primary knobs conveys the warmness of analog sound, and the wood side panels are painted black to blend in with the overall aesthetic.
