  • 【Enhanced Signal Coverage with Dual Antenna System, Additional Signal Boards for Extended and Uniform Coverage】: Featuring a mainboard with a built-in antenna and two external 150mm large-sized antennas, our device can simultaneously output five channels of identical frequency signals. This configuration easily blankets your bedroom, living room, or office space, allowing the Schumann wave to permeate evenly throughout the environment, significantly enhancing your usage experience.
  • [High-Precision Pure Sine Wave Output, Accurate Adjustable Frequency]: Utilizing DDS (Direct Digital Synthesis) technology, the device reliably outputs pure sine waves ranging from 0.01Hz to 9999Hz. With a default resonance frequency of 7.83Hz, which reflects the Schumann resonance base frequency, the device ensures minimal error, delivering a pure and stable signal that caters to users with high precision frequency demands.
  • 【Intuitive Operation with Transparent Design, Clear Acrylic Shell and Digital Display】: The transparent shell allows for an unobstructed view of the internal circuitry and antenna structure, exuding a high-tech feel. The four-digit digital display provides real-time frequency readings, complemented by three parameter adjustment buttons for easy operation, making it user-friendly for beginners as well.
  • [Safe and Durable Power Supply, Type-C Power Supply with Overload Protection]: The device supports a 5V Type-C power supply (compatible with Type-C to Type-C cables) and incorporates built-in overcurrent and overvoltage protection circuits. Operating at a low current of only 15–30mA, this low-power design ensures safety and durability, providing peace of mind for long-term use.
  • [Designed for Relaxation and Sleep Enhancement, Enhancing Physical and Sensory Awareness]: By simulating the Earth's natural resonance frequency, this device promotes relaxation and improves sleep quality. Users have reported enhanced perception of sounds and visuals, making it suitable for meditation, sleep assistance, and stress reduction scenarios. This description ensures that all the key features you highlighted are conveyed clearly and effectively to potential customers.
