A Schumann generator for your listening room

7.83 Hz, precise and constant

The S1 creates an electromagnetic field at 7.83 Hz, the natural Schumann resonance frequency. It harmonises the electromagnetic environment in your listening room. You hear more calm in the sound, a clearer spatial image and a more relaxed, natural music experience, regardless of room acoustics or system setup.

Built like a hi-fi amplifier

Discrete, with no integrated circuits

The analogue section follows classic audio architecture: a linear power supply with ample reserves, an external mains transformer against 50 Hz stray fields, fast low-noise rectifier diodes, discrete voltage regulation and a fully symmetrical high-current driver stage. The result is a stable, clean signal that stays constant between −20 °C and +60 °C.

Antennas

Besides the integrated bifilar antenna, the S1 has two 3.5 mm jacks for external throw antennas. The antennas are included and allow targeted excitation of the room.

Made in Germany

The S1 is made in Germany, with the experience of more than 40 years of SteinMusic. You will find more products for your listening room in our room acoustics category, for example the H2 Neo.

Frequently asked questions about the Schumann Generator S1

Where do I place the S1 and the antennas?

Ideally, the external antennas sit at a height of about 1 m, aligned symmetrically to the listening position.

Does the S1 work with my room and my components?

Yes. The effect does not depend on room acoustics or system setup, because the S1 acts on the electromagnetic environment of the listening room.

Does the S1 need readjusting?

No. The components work consistently between −20 °C and +60 °C, without frequency drift. Once tuned, the S1 stays precise.

How quickly will I hear a difference?

Usually within a few minutes.
