GZLOZONE power processing - subverting the traditional - F30A-HiFi dedicated filter plug (original design) multiple specifications to choose from
In the modern living environment, the quality of the power grid is getting worse and worse, and there is a lot of interference. It is enough to make a good system fall to a few levels.
The power processing method can be summarized into three general forms: EMI filter series, isolation transformer series, and regenerative power supply series.
Traditional EMI filters are widely used in products with switching power supplies because of their small size. Yes, they are used on switching power supplies. Their main function is to prevent the interference generated by switching power supplies from flowing back to the power grid. Conscience switching power supplies are available. Will be equipped with EMI filters.
Whether the traditional EMI filter can clean the noise of the city grid can, but it has little effect; ZERO-ZONE believes that the main role of traditional EMI is not to filter, but to prevent switching power supply interference from flowing back to the city grid. Many HIFI players seem to have verified this phenomenon.
The F30A is a HiFi-dedicated power supply box for the enthusiasts of the ZERO-ZONE team. The filter structure is ZERO-ZONE original, the core device uses custom-grade components under the new material technology, and the device is configured according to HiFi requirements, which can greatly reduce the AC power or the city grid. UHF noise and DC components in the middle.
The ultra-high frequency noise and DC component in the power grid are synchronous. The common performance of ultra-high frequency noise on HiFi-AV is: the background is not clean and not black, a bit noisy, the resolution is not high, the low frequency is a bit turbid, and the image quality is clear. Not enough, sharpness is not enough; the DC component is too high, often the transformer (bovine) is called or vibrated. It is often heard late at night (provided that the voltage is too high).
The F30A original architecture is equipped with targeted filtering of UHF noise in the city&x27;s power grid and DC components in the city&x27;s power grid. It can be applied to almost all home HiFi-AV equipment (including post-amplifiers) without any negative impact.
Many commercially available filters, including filters for HiFi, are rarely configured with DC component filtering.
The F30A has a maximum current peak of 30A. Under the high current peak design, it has a lower power supply internal resistance, a stronger dynamic response speed, a larger power reserve, and a dynamic influence on the power supply filter transmitted by the square. Will not appear.
The general filter affects music dynamics, the main reason is:
The customer selection is not correct, that is, the power selection is small.
Manufacturer parameter virtual standard
Traditional filters are limited by cost, resulting in excessive resistance internal resistance
Non-HiFi-specific design, only for switching power supply products (the market demand is very large)
Using F30A, the effect does not need to open "brain release", ZERO-ZONE statistics: power supply noise drops 50MV, old-fashioned fans have been able to separate the effect, the decline of 80MV is very obvious; drop 100MV, the general fan has been distinguished from one ear, It may take up to 20 minutes for the initial burn.
F30A, ZERO-ZONE test results, noise reduction exceeds 150MV
For better results, the F30A series products need a grounding wire (if there is no ground wire or poor ground wire quality when the home is installed, the ground wire can be connected to the aluminum alloy door and window)
