Schumann Generator S1 Sale price€998

“A true audiophile enhancement… more depth, a more refined soundstage, and a lot more clarity… a must own in my opinion.”

Precision in its purest form.
The S1 generates a precise electromagnetic field at 7.83 Hz – the natural Schumann resonance frequency.
This field harmonizes the electromagnetic environment in your listening room and has a calming effect on the central nervous system.

The result: greater calmness in the soundstage, clearer spatial imaging, and a more relaxed, natural listening experience – regardless of room acoustics or system setup.

The S1 was developed to make this effect truly tangible – with maximum precision, stability, and technical finesse.
For those who don’t just listen to music but immerse themselves in it.
Exact frequency – individually calibrated
Each unit is individually fine-tuned to the Schumann resonance frequency of 7.83 Hz – not as a fixed factory setting, but as precise, single-unit calibration. The distortion factor is also manually minimized to ensure a pure, undistorted signal.
Discrete circuitry – uncompromisingly analog
Unlike many conventional products, the S1 operates entirely without integrated circuits. Every stage of the signal path is discretely built, using selected high-grade components for maximum stability and long-term consistency.
Built like a high-end amplifier
The analog section of the S1 follows the design principles of true high-end audio electronics:
  • Linear power supply with generous performance reserves
  • External transformer to eliminate 50 Hz interference fields
  • Fast, low-noise rectifier diodes
  • Discrete voltage regulation – no standard regulators
  • Fully symmetrical high-current driver stage
  • Double-sided gold-plated circuit board with through-hole plating

The result : a highly stable, exceptionally clean electromagnetic signal – the perfect foundation for a relaxed, natural sound experience.
Temperature stability & long-term consistency
Carefully selected components ensure constant performance between –20 °C and +60 °C. No retuning required, no frequency drift – once calibrated, always precise.
Flexible antenna configuration
In addition to the integrated bifilar antenna, the S1 features two 3.5 mm jack outputs for external throw antennas (included).
These allow for optimized room coupling, ideally positioned at about 1 m height and symmetrically aligned with the listening area.

Made in Germany – backed by over 40 years of experience in uncompromising audio craftsmanship.
For those who seek more than sound – who seek presence.
