eBay Introduction: Subverting the traditional F30A HiFi-specific Filter Distributor (ZERO-ZONE original design) Play HiFi first to play « power », a good set of power processing, will make your system produce « quality » flyby! 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, due to their small size, are widely used in products with switching power supplies. Their main function is to prevent the interference generated by switching power supplies from flowing back to the city grid. Whether the traditional EMI filter can clean the noise of the city grid, Yes can, but the effect is very small; ZERO-ZONE believes that the main role of the traditional EMI is not to filter, but to prevent the switching power supply interference from flowing back to the city grid. Many HIFI players seem to have verified this phenomenon. F30A is HiFi-specific power supply box launched by ZERO-ZONE team for audiophile. The filter structure is original design of ZERO-ZONE. The core device uses custom-grade components under new material technology. The device is configured according to HiFi requirements, which can greatly reduce AC power or city. Ultra-high frequency noise and DC components in the power grid. 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, there is a bit of noisy, the resolution is not high, the low frequency is a bit turbid, and the image quality is clear. Insufficient contrast, insufficient sharpness, etc.; excessive DC component often appears as a transformer scream or vibration. It is often audible in the middle of the night (provided that the voltage is too high). The F30A original architecture is equipped with targeted filtering of UHF noise in the city’ The general filter affects music dynamics, the main reason is: 1, the buyer’s selection is not correct, that is, the power selection is small 2, manufacturer parameters virtual standard 3, the traditional filter is limited by cost, resulting in excessive resistance internal resistance 4, non-HiFi-specific design, only for switching power supply products (market demand is very large) After using F30A, the effect does not need to be « worried »: ZERO-ZONE statistics: power supply noise drops by 50mV, the old level audiophile can directly hear their respective effects, down to 80mV is very obvious; down to 100mV, the middle level audiophile can be distinguished from one ear, beginner audiophile may need to listen to 20 minute. The F30A passed the ZERO-ZONE test and the noise dropped by more than 150mV. For better use, the F30A product requires a grounding wire. (If you have no ground wire or poor ground wire quality when you install it, you can use the GND terminal on the backplane to connect the wire to the aluminum alloy door and window.)
