7.83HZ 0.01H-100KH compatible with Resonance Pulse Sine Wave Generator 3.5MM Audio Frequency Saved When Power OFF

compatible with Wave itself does not act directly on sound or video products to improve sound quality, but on the space environment, which can relax people's body and mind, improve the body's perception of sound andimages, improve thehealth of the human body and work efficiency, and relieve psychological pressure. This product not only can output 7.83Hz SchumannWave, but also can adjust the frequency in the range of 0.01Hz-100KHz, the digital circuit crystal oscillator frequency reference, more stable and strong anti-interference. This is a version of compatible with Wave adjustable signal generator, which uses a low-temperature drift crystal oscillator and a high-precision dedicated chip. It can accurately output frequency and pure sine wave. compatible with audio-visual space - to enhance the sound field and audio-visual effects. compatible with the bedroom - to help sleep soothe the nerves, treatment of insomnia. compatible with the office - relax and improve work efficiency. compatible with the create space - to improve inspiration. compatible with the tea ceremony, spirituality, realization space - resting body and mind.
