PFC (Power Factor Corrector)
The power factor corrector greatly improves the efficiency of the system. Performances of the amplifier are very stable and consistent, regardless of the quality of the mains.
This also grants a worldwide compatibility of the power supply (from 90V to 265V 50/60Hz) and limits power consumption.
The cross over (X-over) is the intersection point of different frequencies from different ranges. In sound systems it delimitates the areas in which low, mid, and high frequencies work. A cross over is also an electronic object, active or passive, which comands the division of the frequencies' areas. In other words, it separates an incoming full range signal into two or more areas of frequency.
