Frequently Asked Questions

Q: What frequency does the Schumann Wave Signal Generator default to when powered on?

A: The device defaults to 7.83 Hz upon startup — the classic Schumann resonance frequency. You can manually adjust the frequency anywhere from 0.01 Hz to 9999 Hz using the digital controls.

Q: What power source does this generator use, and is a charger included?

A: The generator uses a 5V 2A Type-C connection, making it compatible with standard mobile phone chargers and USB power banks. A power cable is included in the box, but a charger is not — most USB-C chargers you already own will work perfectly.

Q: What does the 3.5mm audio jack do?

A: The built-in 3.5mm audio jack lets you connect headphones or external speakers. Different frequencies produce distinct audible tones — lower frequencies (below 2000 Hz) are clearly perceptible as sound, while higher frequencies (above 2000 Hz) are outside the range of human hearing. The jack can also power an LED diode (under 1W) for scientific or experimental use.

Q: What is the effective operating range of the device?

A: Under normal use, the Schumann Wave Signal Generator has an effective range of approximately 10 square metres, making it well suited for a bedroom, study, home office, or small yoga studio.

Q: Is this device CE and RoHS certified?

A: Yes. The Gaqqee Schumann Wave Signal Generator carries both CE and RoHS certification, confirming it meets European safety and environmental standards. It also contains no high-concern chemicals.
