Features 1、HOW IT WORKS: The Schuman generator itself does not make any sound. Just plug in and use. No need to connect to another device. Does not directly act on audio or video products to improve sound quality and image quality, but act on the spatial environment to provide electromagnetic waves of specific frequencies 2、RELAXING EFFECT: Schumann wave 7.83Hz pure sine wave eliminate the frequency of electromagnetic wave and radio wave negative interference, making the sound space stable and harmonious, and the listener can enjoy the music more attentively and happily. Relax people physically and mentally, improve the human body perception of sound and images, improve human health, improve the efficiency of work creation, and also have a certain effect on insomnia and mental tension 3、STABLE SIGNAL SOURCE: Schuman wave generator adopt DSP signal synthesis technology, which has the characteristics of high signal stability and high frequency stability 4、POWER SUPPLY: The Schumann wave pulse generator supplies 5V power through the Micro USB port. Mobile phone chargers and power supplies are available. Breathing light indicate operation, can assist sleep 5、DUAL DIFFERENTIAL POWER OUTPUT: The audio resonator has a dual differential high fidelity drive circuit, which has stronger output capacity, strong output and no distortion of waveform 6、EXTERNAL PORT: The ultra low frequency pulse generator can be connected to an external oscilloscope to observe the waveform. You can also connect the external speaker, and you can feel the wave vibration with your hand Specification Item Type: Schuman Wave Generator Material: Acrylic and PCB Power Supply Voltage: 5V(USB interface) Rated Current: 0.5A Signal Waveform: Pure sine wave Application: 1. HIFI application HIFI Application Principle: Drive away clutter, purify listening environment, improve people perception = system improvement a. HIFI Speaker System Application: When listening to the environment within 18 square meters, the Schuman wave generator is placed in the middle of the two speakers, slightly behind the position, if conditions are recommended to be placed in 1.2-1.5m/3.9-4.9ft height, the prevent vibration treatment of Schuman wave can increase the effect. When the listening environment is greater than 18 square meters, it is recommended to buy two Schuman wave generators, which can be placed above or beside the box, and other requirements are the same as above. b. HIFI Headset Amplifier System: Since only headphones are used for listening, the only thing left in principle is improving human perception, and the effect is greatly diminished, but it still exists. 2. AV films and paintings The number and location of the required Schuman wave generator is consistent with the HIFI application, and four Schuman wave generators are recommended for use over 40 square meters. 3. Sleep Aid: There are individual differences. Some people use the product for the first time, and the quality of sleep in the second half of the night is not very high. After a few days of adaptation, the user can achieve deep sleep. Long term use of this product will be more significant. 4. Create: Often used in calligraphy, painting and designers. Can calm the mind (recommended for office use). 5. Other Instructions: Researchers in the fields of meditation, martial arts, cultural studies of The Book of Changes, biology, medicine, etc. Package List 1 x Schuman Wave Generator(random screw style and capacitor color) 1 x USB Cable
