AlphaTheta Euphonia - 4-channel Rotary Mixer

AlphaTheta's Euphonia distills decades of iconic designs and turntable history into a 4-channel rotary mixer that has DJs inspired and enchanted by AlphaTheta’s unwavering craftsmanship. This mixer fuses traditional interfaces 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 layer of shimmering harmonics and an energetic finish to give your continuous mix even greater flair. Its comprehensive per-channel EQ suite, 3-band master channel isolator, and onboard effects are complemented by innovative performance tools, multiple effects sends, and multi-mode compatibility that lets you enjoy Euphonia’s distinct sonic character with Serato and rekordbox, in addition to classic vinyl. With a variety of output options and a contemporary, responsive tactility, AlphaTheta's Euphonia is unmatched in its modular mixing capabilities — elevate any DJ setup with an ode to the hi-fi history that started it all.

Next-Gen Precision, Detail, and Tactility

Euphonia effortlessly unites the iconic characteristics of analog output with the precision and clarity of the digital domain, resulting in a unique mixer that pairs 32-bit A/D and D/A converters with 96kHz/64-bit DSP for rich, unmatched sonic depth. Handling your sound in a hands-on way has never been so inspiring, thanks to AlphaTheta-developed custom knob designs. Following extensive testing and experimentation, Euphonia’s control points were coated in elastomer to eliminate almost all vibration, while maximizing both comfort and grip to ensure detailed control and satisfying tactility. What's more, these knobs boast a dynamic architecture that modifies their behavior to adapt to the weight applied to the rotary motion, meaning slower rotations are mechanically weighted to allow for ultra-fine resolution in your long-form blends. Meanwhile, faster rotations adjust to the speed of your movement to support focused, evocative expression in your performances.

One-Handed Dynamic Effects and Innovative Isolator Design

One of the historical elements of rotary mixers is their isolator, and AlphaTheta honors that emblematic characteristic by outfitting the Euphonia with a master class 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 deliver an added dimension of mixing possibilities. But why stop there? Euphonia boasts a suite of five onboard spatial effects — delay, tape echo, echo verb, reverb, and shimmer — accompanied by a highpass filter and an external option for using Send FX. When an effect is present, engaging the Isolator’s “Send” button allows the effect to be applied to that band, proportionally saturating with a continuous clockwise rotation. What's more, you have up to 12 decibels of boost available to instantly reinforce the effect send, ensuring stable levels during your carefully crafted transition. With one-handed control to apply an effect while adjusting the Isolator band, you can conjure innovative mixing opportunities across Euphonia’s 4-channel array, thanks to that free hand.

Comprehensive Interface for Mixing Your Way

Paying homage to the earliest days of DJing, AlphaTheta has outfitted the Euphonia with an extensive list of controls to ensure total congruence with your sonic vision. Each channel includes a Trim control, level meter, 3-band EQ, Cue designation, and Send knob, along with a 4-point input selector that lets you blend and mix Phono, Line, Digital, or computer sound sources. A dedicated 2-band EQ and Level knob provide additional control over your Booth output, while headphone playback can toggle between standard stereo and a mono split. For DJs who use in-ear monitors, this second option — known as “split cueing” — allows your Cue signal and master output to be played in mono in each respective ear. For monitoring your mix, Euphonia’s vivid display serves as a multi-mode source of real-time feedback, offering conventional VU-meter readings, as well as a spectral analyzer for granular insight into your sound’s behavior. They’ve even color-coded each channel to give you a full visualization of the entire mix, illustrating how the frequency bands of each channel interact with each other.

Full 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 AlphaTheta has honed for years, no effort was spared in ensuring the Euphonia preserves every nuance of your tracks. Masterfully balancing the digital and analog, DJs of any style — be it new or classic — can make use of Euphonia’s sound-shaping toolkit. Pairs of Phono and Line inputs are offered for each channel, in addition to four digital inputs, two signal ground contacts, and a USB-C port for connecting your laptop and taking advantage of Euphonia’s onboard support for rekordbox and Serato, should vinyls not be your preference. Stereo pairs are offered for your Master output, your Booth output, and a dedicated record output, in XLR, TRS, and RCA terminals, respectively. The record output can be used with supplementary gear, such as a power amp. Add to this the fact that Euphonia’s suite of Send FX and Master Insert pairs let you incorporate virtually any external audio processing into your setup, and you can be sure that AlphaTheta has prepared the Euphonia for electrifying performances.
