product description
To play HiFi, first play with electricity, which is basically recognized by us; 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 reduce a good system by several levels.
Power processing methods can be summarized in three forms: EMI filter series, isolation transformer series, and regenerative power supply series.
Traditional EMI filters are widely used in products with switching power supplies due to their small size. Their main function is to prevent the interference generated by switching power supplies from flowing back to the city grid. A conscientious switching power supply developer Will be equipped with EMI filters.
Whether the traditional EMI filter can purify the noise of the municipal power grid can, but the effect is not obvious; we believe that the more main function of the traditional EMI is not to filter, but to prevent the interference of the switching power supply from flowing back to the municipal power grid. Many HI-FI players seem to have verified this phenomenon.
F30A is a Hi-Fi special power box launched by our team for enthusiasts. The filter structure is our original, core components using custom-made components under new material technology. The components are configured according to HiFi requirements, which can greatly reduce the AC power supply or the city grid. Ultra high frequency noise and DC component.
The UHF noise and the DC component in the power grid exist synchronously. UHF noise is common on HiFi-AV: the background is not clean and not dark, a bit noisy, the resolution is not high, the low frequency is a bit turbid, and the picture is clear and clear. The contrast is not enough, the sharpness is not enough, etc.; the DC component is too high, which is often manifested as transformer squeal or vibration. It is often heard late at night (provided that it is necessary to rule out whether the voltage is too high).
The F30A original architecture is equipped with targeted filtering of UHF noise in the municipal power grid and DC components in the municipal power grid. It can be applied to almost all household HiFi-AV equipment (including power amplifiers), and there is no negative impact.
Many filters on the market, including those for HiFi, are rarely equipped with DC component filtering.
The maximum current peak value of F30A is 30A. Under the high current peak design, it has lower power supply internal resistance, stronger dynamic response speed, and larger power reserve. It is said that the power filter affects the dynamics of the power supply filter. Won't show up.
Generally, traditional filters affect music dynamics, and the main reasons are summarized:
1. The customer's selection is not correct, that is, the power selection is small.
2. False label of manufacturer parameters.
3. Due to the cost limitation of traditional filters, the internal resistance of the resistance is too large.
4. Non-HiFi professional design, only for switching power supply products (the market demand for such products is very large)
Using the F30A power processor, the effect does not require meditation. Our preliminary statistics: the power noise is reduced by 50MV, and old players can distinguish the effect. The reduction of 80MV is very obvious; the drop of 100MV is distinguished by ordinary fans, and junior players may It takes about 20 minutes.
F30A, the test result of our team, the noise drop exceeds 150MV
(See test chart or test video).
For better results, F30A series products need a ground wire (if there is no ground wire during home improvement or the ground wire is of poor quality, you can use the randomly equipped ground wire to connect to aluminum alloy doors and windows)
