Features:

1.This product is made of high-quality materials, using low-temperature drift crystal oscillators and high-precision DAC dedicated chips, resulting in good frequency stability of the product;

2.This product not only outputs 7.83Hz Schumann waves, but also incorporates programmable frequency modulation technology, which can adjust the frequency in the range of 0.01Hz to 100000Hz;

3.2 specifications, available in two options: without casing and with casing, to be selected according to demand;

4. Digital circuit crystal oscillator frequency reference, more stable and stronger anti-interference;

5. The power interface adopts Type-C interface, which is convenient to use and supports Type-C to Type-C power supply.

Product Description:

Schumann waves themselves do not directly act on sound or video products to improve sound quality, but rather on the spatial environment, relaxing the body and mind, improving the body's perception of sound and images, 

Improving the efficiency of human health work, and relieving psychological stress. They also have good effects. 

This product can not only output 7.83Hz Schumann waves, but also adjust the frequency within the range of 0.01Hz-100KHz. 

The digital circuit crystal oscillator frequency reference is more stable and has stronger anti-interference capabilities. 

It uses low-temperature drift crystal oscillators and high-precision DAC dedicated chips, which can accurately output frequencies and pure sine waves.
