Adjustable Frequency Generator for Improving (0.01Hz-100kHz ）7.83Hz Schumann Resonance Generator USB-C Powered Sine Wave Signal Generator for Sleep Yoga Meditation & Stress (2X with Shell)

Description:This product not only can output 7.83Hz SchumannWave, but also can adjust the frequency in the range of 0.01Hz-100KHz, the digital circuit crystal oscillator frequency reference, more stable and strong anti-interference.This is a new version of eletechsup's Schumann Wave adjustable signal generator, which uses a low-temperature drift crystal oscillator and a high-precision DAC dedicated chip. It can accurately output frequency and pure sine wave.In addition to 7.83Hz, the following frequencies are also beneficial to the body: 0.83 6.5 14.3, 20.8, 27.3, and 33.8Hz(33.81Hz)With Acrylic Shell Version :1 Working voltage: DC 5V (DC 4-15V)2 Working current: 9-14MA3 Power interface: Type-c(Support TYPE-C TO TYPE-C power supply)4 Default frequency: 7.83Hz5 Adjustment range: 0.01Hz~100000Hz Pure Sine Wave6 Signal voltage amplitude: 3V7 With 3.5MM audio output8 With acrylic shell9 Size: 155*105*26MM(With shell)10 Weight : 197g(With shell)No Acrylic Shell Version :1 Working voltage: DC 5V (DC 4-15V)2 Working current: 8-14MA3 Power interface: Type-c(Support TYPE-C TO TYPE-C power supply)4 Default frequency: 7.83Hz5 Adjustment range: 0.01Hz~100000Hz Pure Sine Wave6 Signal voltage amplitude: 3V7 PCB Board Size: 150*100*12MM8 Weight : 86gFor more information please Google ''Schumann Resonance''.For audio-visual space - to enhance the sound field and audio-visual effectsFor the bedroom - to help sleep soothe the nerves, treatment of insomniaFor the office - relax and improve work efficiencyFor the create space - to improve creative inspirationFor the tea ceremony, spirituality, realization space - resting body and mind(Uses TYPE-C power supply and supports all TYPE-C power supplies.Note : Since TYPE-C cables are now widely used, no additional TYPE-C power supply cables are provided.)Q&A:Q1:How to change the output frequency?A1:Press the ''0-9'' and '.' buttons to enter the value, and press the OK button to confirm. If the input is wrong, press the SET button to re-enter.For example, press [9][.][7][1], then press [OK], you can set to 9.71Hz, the default power-on output is 9.71Hz, and the setting range is 0.01~100KHz(Note: Not all frequency points can be set)Q2:Need to save parameters even after power off?A2:Please press and hold the ''SET'' button until the LCD displays ''Data Save ON''Q3: How to verify the output waveform?A3: Please use an oscilloscope to measure the ''GND/SIN'' port. You can see a pure sine wave.Q4: How to turn off the LCD backlight?A4:Short press the ''BACKLIGHT'' button to turn off the LCD backlight; short press the ''BACKLIGHT'' button again to turn on the LCD backlightQ5:How to turn off the output signal indication (PWR LED)?A5:Long press the ''BACKLIGHT'' button to turn off the output signal indication; long press the ''BACKLIGHT'' button again to turn on the output signal indication.Q6:LCD does not display correctly after power on?A6:Please press the RES button briefly and power on again
