AlphaTheta Euphonia Professional 4-Channel Rotary Mixer

Upgrade your DJ performance with the innovative AlphaTheta Euphonia, a premium 4-channel rotary mixer that combines the clarity of digital with the richness of analog. The Euphonia features 96 kHz / 32-bit ADDA converters and 96 kHz / 64-bit floating point internal DSP processing for clear and accurate sound reproduction. The analog signal passes through a Rupert Neve-designed transformer, which adds harmonics to the music and creates a glossy and energetic sound that’s smoother for mixing.

Other notable features include specially developed rotary faders with optimized and dynamic fader curves that adjust to your playing style, an energy visualizer and master spectrum analyzer, and a next-generation 3-band master isolator with boost and send FX for each band. Additionally, there are 5 integrated spatial effects (Delay, Tape Echo, Echo Reverb, Reverb, Shimmer, and HPF) as well as a dedicated Send/Return section. Each channel features stereo RCA inputs for both line and phono as well as digital coaxial inputs. XLR master output, RCA record output, and dual 1/4" TRS booth outputs provide ample connections to your PA and monitoring system. The Euphonia ships with a locking IEC cable.

Euphoric Sound with Digital Clarity and Analog Polish with Rupert Neve Transformer

  • The euphonia produces a euphoric sound with the clarity of digital and the richness 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 96 kHz/64-bit 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 punchier, 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 Faders

  • 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 higher load is applied when you turn a knob slowly for delicate fine-tuning and a lower load level is applied when you turn a knob quickly to instantly reach your intended volume level.
  • 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

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. 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.

Innovative 3-Band Master Isolator

Enjoy a more sensory level of control over your music with the 3-Band Master Isolator, which was specially built for the euphonia.

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 band 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 +12 dB for dynamic performances, +6 dB for sound quality adjustments, and +0 dB for reverb effects without any volume boost.

Built-In Send FX

  • 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). There’s also a Send/Return section, which gives 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.
  • 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.

Unique Design

The euphonia was designed to signal 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.
