Features:

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

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

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

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

Product Description:

Shumanbo itself does not directly act on sound or video products to improve sound quality, but rather acts on the spatial environment to relax the body and mind, enhance the body's perception of sound and images, improve the efficiency of human health work, and relieve psychological pressure. 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. It uses a low-temperature drift crystal oscillator and a high-precision DAC dedicated chip, which can accurately output frequency and pure sine wave.
