Features HOW IT WORKS: The Schuman generator itself makes no sound. Plug it in and use it. No need to connect to another device. Does not act directly on audio or video products to improve sound quality and image quality, but acts on the spatial environment RELAXING EFFECT: The pure sine wave Schumann wave 7.83 Hz eliminates the negative interference frequency of electromagnetic waves and radio waves, making the sound space stable and harmonious, and the listener can enjoy the music more attentively and more happily. Concerning STABLE SIGNAL SOURCE: Schuman wave generator adopts DSP signal synthesis technology, which has the characteristics of high signal stability and high frequency stability POWER SUPPLY: The Schumann wave pulse generator provides 5V power via the micro USB port. Mobile phone chargers and power supplies are available. Breathing light indicates operation, can help sleep DOUBLE DIFFERENTIAL OUTPUT POWER: The audio resonator has a high-fidelity double differential drive circuit, which has stronger output capacity, strong output and no waveform distortion. Feature: 1. 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 feel the vibration of the waves with your hand Specification: Item type: Schuman wave generator Material: Acrylic and PCB Power supply voltage: 5V (USB interface) Rated current: 0.5 A Signal waveform: pure sine wave Application: 1. HIFI application HIFI application principle: eliminate clutter, purify the listening environment, improve people's perception = system improvement A. Application of HIFI speaker system: When listening to an environment within a radius of 18 square meters, the Schuman wave generator is placed in the middle of the two speakers, slightly behind the position. If conditions are suitable, it is recommended to place it at a height of 1.2-1.5m/3.9-4.9ft. Schuman wave vibration treatment can increase the effect. When the listening environment is larger than 18 square meters, it is recommended to purchase two Schuman wave generators, which can be placed above or next to the box, and the other requirements are the same as below. on it. b. HIFI headphone amplifier system: Since only headphones are used for listening, the only thing left in principle is to improve human perception, and the effect is greatly diminished, but it still exists. 2. Films and audiovisual 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 in 40 square meters.
