What our devices do, in plain terms.

This page explains what Amatro devices actually are, the documented physics around them, and, just as important, what we do not claim.

What the devices are.

An Amatro frequency device is a precision signal generator. You choose a number, measured in hertz, and the device produces that frequency as a clean, steady sine wave. Our TrueWave line produces one exact frequency at a time. Our Spectrum design sends the frequency you set through seventeen concentric rings of different diameters, following a geometry patented in 1934, so the signal carries its harmonic range.

That is the whole machine. A number you choose, produced precisely.

Resonance, the physics idea behind it all.

Resonance is one of the oldest ideas in physics. Every object has frequencies at which it naturally vibrates. Strike a tuning fork and hold it near a second fork of the same note, and the second one begins to hum on its own. Nothing touched it. The frequency did.

That is not a theory. It is a classroom demonstration, and it is the idea that fascinated the engineers of the 1930s.

The Earth has a frequency too.

In 1952, the physicist Winfried Otto Schumann described what is now called the Schumann resonance: a set of natural electromagnetic resonances in the space between the Earth's surface and the ionosphere, with a base frequency of about 7.83 hertz. It has been measured and documented continuously since. It is one of the most famous numbers in this field, and one of the reasons frequency research has never fully gone away.

The 1934 geometry.

US Patent 1,962,565, granted to Georges Lakhovsky in June 1934, describes an apparatus with circuits oscillating under multiple wave lengths: split rings of different diameters, insulated from each other, each responding to its own wavelength. Our Spectrum design is built to that documented geometry. You can read the original patent in the public archives of the United States Patent Office.

What we do not claim.

We think you should hear this from us directly.

Amatro devices are consumer wellness and lifestyle products. They are not medical devices. They have not been evaluated by the FDA. They do not diagnose, treat, cure, or prevent any disease or condition, and we make no health claims for them.

People use our products as part of quiet evening routines, the way people use singing bowls, tuning forks, or a wind-down ritual. Individual experiences vary.

If you have a medical condition, an implanted electronic device such as a pacemaker, or if you are pregnant, do not use electronic frequency products and consult a healthcare professional.

That is our whole position. The history is real, the engineering is real, and the decision about whether this belongs in your evening is yours.
