Features:
1. This product is made of high quality materials, using low temperature drift crystal oscillator and high precision DAC special chip, the product has good frequency stability;
2. This product not only can output 7.83Hz Schumann wave, but also joined the programmable frequency modulation technology, can be adjusted in the range of 0.01Hz ~ 100000Hz frequency;
3. Digital circuit crystal frequency reference, more stable, stronger anti-interference;
4. Power supply interface adopts Type-c interface, easy to use, support Type-c to Type-c power supply.
Product Description:
Schumann wave itself is not a direct role in the sound or video products to improve sound quality, but the role of the spatial environment, so that people's physical and mental relaxation, improve the body's perception of sound and images, improve the health of the human body to improve the efficiency of the work of the human body, and alleviate the psychological pressure also has a better effect. The product can not only output 7.83Hz Schumann wave, but also can be adjusted in the range of 0.01Hz-100KHz frequency, digital circuit crystal oscillator frequency reference, more stable, stronger anti-interference, the use of low-temperature drift crystal oscillator and high-precision DAC special chip, you can accurately output the frequency and pure sine wave.
