Tunable Frequency: This sine wave generator offers a tunable range from 0.01 Hz to 200,000 Hz, enabling flexible configuration to suit various requirements. The default setting is 7.83 Hz, with additional preset options including 10 Hz, 40 Hz, 174 Hz, 285 Hz, 396 Hz, 417 Hz, 432 Hz, 528 Hz, 639 Hz, 741 Hz, 852 Hz, 963 Hz, and beyond.
Three Waveform Outputs: Capable of generating sine, square, and inverse square wave patterns. This selection provides configuration flexibility and supports applications requiring specific signal characteristics
Two Testing Methods: The device is equipped with a Schumann wave detector and wired headphones, allowing you to easily verify its proper operation through two simple methods. You can either measure directly with the detector or listen via the headphones to confirm the frequency. These options make it user-friendly for anyone and ensure the device is functioning correctly (since the product itself operates silently)
Recommended Setup‌: Position the device at 3.3–4.9 ft (1–1.5 m) height for a working range up to 16.4 ft (5 m). For large rooms or open areas, use two units for full coverage. Best in quiet settings; effectiveness may drop after intense activity or in noisy places (e.g., live DJ events)
Compact & Portable Design: This plug-and-play sound frequency generator measures 5.9 x 5.5 x 1.2 inches (protective case suggest size is 6.3 x 5.9 x 1.57 inches sold separately–not include). Its USB Type-C connectivity ensures instant operation anywhere
