AlphaTheta/Pioneer DJ Release Euphonia Rotary Mixer

The Euphonia is a professional rotary mixer from AlphaTheta that combines the clarity of digital with the richness of analog sound, promising an immersive musical experience for both DJs and their audiences.

AlphaTheta, the parent brand that owns Pioneer DJ, has announced the release of its first ever mixer. Euphonia is a rotary mixer, meaning that it uses rotary dials to mix between channels instead of faders.

Euphonia is a hybrid digitial/analogue 4-channel mixer built around a transformer circuit developed in collaboration with Rupert Neve Designs, which AlphaTheta tells us is tuned specifically for the unit, adding harmonics and culminating in a “glossy and energetic” sound.

The mixer is equipped with high-quality 32-bit A/D and D/A converters and uses 96kHz/64bit floating point processing in its DSP, which powers a number of digital effects including reverb, tape echo, and delay. External effects can be hooked up via the Send/Return section.

AlphaTheta is making a big deal of the mixer’s elastomer-coated rotary dials, which have been specially designed to provide intuitive and precise control, and will vary in resistance depending on how fast you turn them; their volume curves have also been fine-tuned in response to feedback from DJs.

Euphonia’s interface is split-level, with the top of the unit featuring a 3-band master isolator section with Boost Send buttons for applying effects, alongside a display AlphaTheta has dubbed the Energy Visualizer. Unlike a traditional VU meter, the display features a needle for each of the mixer’s channels and a spectrum analyzer for the master channel.

The remainder of the unit is taken up by controls for the mixer’s 4 channels, which showcase a design closer to that of Pioneer’s DJM mixers than a traditional rotary mixer.

Connectivity-wise, Euphonia is well-equipped, with four RCA outputs at both line and phono level, four coaxial digital inputs, and XLR and 1/4″ TRS mic inputs. We have an XLR master output, 1/4″ TRS booth output, and RCA output for recording, along with two headphone outputs, 1/4″ and 3.5mm. There’s also two 1/4″ TRS sends and returns and a USB-C port for hooking up with Rekordbox, Traktor and Serato.


  • Enhanced harmonics in your music, thanks to a Rupert Neve Designs transformer.
  • Specially developed rotary faders, designed to make you feel at one with the music.
  • Energy Visualizer for understanding overall sound at first glance.
  • Next-generation 3Band Master Isolator.
  • Built-in Send FX to bring depth and breadth to your sound.
  • Design that embodies a new era of rotary mixer.

Euphonia is priced at $3799/£3249. Find out more on AlphaTheta website.
