The first mixer to bear the AlphaTheta name and the company’s first-ever rotary unit.

AlphaTheta Corporation has announced the release of euphonia from its AlphaTheta brand, a professional 4-channel rotary mixer designed for a natural and smooth mixing experience.

What is a rotary mixer?

A rotary mixer stands as a distinctive alternative to conventional mixers, featuring rotary knobs instead of linear faders for channel control. Renowned for their analog circuitry, rotary mixers offer DJs a tactile experience and a sought-after warmth in sound.

Rotary mixers typically feature a simplified layout and cater to those favoring a minimalist approach while still maintaining high-quality components such as premium audio transformers and potentiometers. These mixers often boast customization options to suit individual preferences and workflows alongside their vintage-inspired aesthetic, incorporating materials like brushed metal and wood.


AlphaTheta, announced earlier this year, is the new brand developed by Pionner DJ. The euphonia builds on their 30 years of innovation while paying homage to rotary mixers.

“We’re so pleased to introduce the euphonia professional rotary mixer,” said Yoshinori Kataoka, AlphaTheta’s President and CEO. “Having watched the DJM Series evolve since I helped develop the first model in 1995, the DJM-500, I have a special feeling about the euphonia. It’s inspired by our customers’ love of music and our dream to create a new expression of the DJ mixer. We’re truly excited to witness the euphonia’s unique sound bringing excitement and inspiration to DJs and their audiences.”

Chasing the holy grail of sound characteristics is made possible by the high-resolution wide-ranging sound design and the inclusion of an analog transformer circuit, co-developed with Rupert Neve Designs, which enhances harmonics in the music to create an energetic and polished sound that enables smooth mixing.

The company states that its focus has been on uniquely developed rotary faders, which have been carefully designed to make users feel a deeper connection with the euphonia. The 3Band Master Isolator was also custom-designed so users can make dynamic changes to the music and have more sensory control over the sound. Beyond that, users can combine the 3Band Master Isolator with the new Boost Send feature for more music and powerful performances. 

All this is just the tip of the euphonia’s “iceberg” as the mixer also features an Energy Visualizer, built-in Send FX, and multiple inputs and outputs.
