В оригинале звучит не так… всё, как обычно.
The AV-grade power adaptor has been designed to reduce electrical noise from AC power and prevent mains quality issues from affecting the network signals. It also boasts high power efficiency, a no-load power consumption < 0.075W and protection from short circuit, overload and over-voltage.
Switches require high speed power supplies so we could not opt for a linear power source due to their speed limitations. We set about improving the power signal by using an extremely high-quality wall supply. This clean supply permits an optimum quality network signal, driven by high-accuracy TCXO clock technology.
