Features: Experience powerful undulation resonance with this 7.83Hz 12V generator, featuring amplified output circuit that deliver low frequency for enhanced environmental energy optimization. Engineered with heat dissipating module and ABS housing, this pulsed undulation generator maintain 12V operational while producing high intensity signals through its 1000+ coil wrapped silicon steel rod for superior electromagnetic field penetration. Ideal for audiophiles seeking enhancement, meditation practitioners requiring relaxation support, and individuals pursuing natural sleep improvement through low frequency undulation synchronization. Effortlessly integrate this sound resonator into home studios for sound optimization, meditation spaces for energy balancing, or bedrooms to create calming electromagnetic environments aligned with Earth's natural frequency. The 7.83Hz output replicates resonance through sine undulation generation, requiring only 12V power input via standard 5.5x2.1mm for continuous operational with automatic thermal management via optimized heat sink design. Specifications: Component:ABS Size:Approx.14x10x3cm/3.94x5.51x1.18inch Power: 20W undulation frequency: standard 7.83HZ Package Includes: 1 Set undulation Generator note: 1.Please allow 1-2cm errors due to manual measurement, making sure that you not mind before order. 2.Due to the differences between different monitors, the picture may not reflect the actual of the item.
