resør 2525 MFX: A Handcrafted Rotary DJ Mixer Focused on Pure Analog Sound
Pure Analog Sound and Tactile Rotary Control for Vinyl DJs and Selectors
2525 MFX represents a very specific philosophy in the world of rotary DJ mixers. Instead of focusing on digital features or complex performance tools, this handcrafted mixer from resør electronics in Berlin concentrates entirely on sound quality and tactile control. Many DJs who prefer rotary mixers look for exactly this approach because the music should remain the center of attention. The 2525 MFX follows this tradition closely by combining a minimalist design with a carefully engineered analog signal path. For selectors, vinyl DJs, and audiophile listening environments, this type of mixer often feels more like a precision instrument than a typical club tool.
Key Features of the 2525 MFX
2525 MFX: Inside the Concept of a Modern Rotary DJ Mixer
At the core of the 2525 MFX sits a fully discrete Class A circuit architecture that aims to preserve the original character of the audio signal. This design keeps the signal path active throughout the entire cycle and reduces crossover distortion, which results in a cleaner and more transparent sound. Each channel features a 3-band Baxandall equalizer that reacts smoothly and musically when shaping frequencies. Rotary DJs often prefer this type of EQ because it allows subtle tonal adjustments instead of aggressive cuts. As a result, transitions between tracks can evolve gradually and feel more natural within longer DJ sets.

One of the most important updates in the 2525 MFX involves the integration of external effects. Each channel includes its own FX send and return path, which allows external processors to become part of the mixing workflow. DJs can route individual channels to hardware units such as delays or modulation processors and blend the processed signal back into the mix.
This setup offers more flexibility than traditional mixers with fixed internal effects. The mixer also features a newly designed 3-band master isolator built with discrete circuitry. When needed, the isolator can remove entire frequency ranges with precision, while a true bypass switch keeps the signal path completely clean when the isolator is not in use.
High-End Components and Discrete Class A Circuit Design
Component choice also plays an important role in the overall design of the 2525 MFX. The signal path includes audiophile grade Mundorf MCap capacitors that aim to deliver higher resolution and faster transient response compared to standard components. Within the channel EQs, the design uses mica capacitors instead of common film capacitors.

Mica components maintain stable electrical characteristics over time and across temperature changes, which supports consistent tonal behavior. Together with the discrete circuit design, these components contribute to a mixer that focuses on clarity and spatial accuracy.
A Minimalist Rotary Mixer Designed for Tactile DJ Control
The physical design of the 2525 MFX reinforces the same philosophy. The mixer sits inside a slim wooden chassis that resembles classic hi fi equipment rather than modern DJ hardware. Urei style rotary knobs add a familiar tactile feel for DJs who prefer rotary mixing techniques. The front panel remains completely clean because it avoids visible screws and unnecessary visual elements.
Analog VU meters provide accurate visual monitoring of signal levels and encourage careful gain staging. At the same time, the FX send controls now sit on the front panel next to the headphone section, which creates a more intuitive workspace. The overall layout keeps the workflow simple and focused, allowing DJs to concentrate entirely on the music flowing through the 2525 MFX.
Price and Availability
The resør Electronics 2525 MFX rotary DJ mixer is available directly from the manufacturer. Pricing and availability may vary depending on configuration and production batches. The 2525 MFX starts at €1,690. Production time is around 6-8 months.
