【 Upgraded Resonance Generator 】- This frequency devices is a new version of eletechsup’s adjustable generator, which uses a low-temperature drift crystal and a high-precision dedicated chip. This frequency generator can accurately output frequency and sine.
【 Stable and Accurate 】- The wave resonance generator operates at the default frequency of 7.83Hz, and the sine amplitude is stabilized at 3V, while the square amplitude is set at 5V. Such setting ensures the stability and accuracy of the output The digital circuit crystal oscillators frequency reference is more stable and have strong antiinterference ability.
【 Adjustable Frequencies 】- This frequency generator for hearing not only outputs 7.83Hz, but also incorporates programmable frequency modulation technology, which can adjust the frequency in the ranges of 0.1HZ-100000HZ.
【 Portable & Lightweight 】- The sine-wave sound frequency machine is 20x14cm/7.87×5.51inch in size, small size, the powered by USB DC 5.5×2.1 interfaces, which is convenient to use, very easy to carry and use at home or when traveling.
【 Promote Pleasure & Relaxation 】- This reverse square sound frequency machine for can emit sine to create a relaxing environment. Do not directly act on sound or video products to improve sound but rather on the environment.
