Re: The Audio Standard Forum.

Ok, so all that means is that unlike a simple way of regenerating mains (convert mains into DC, generate pure sine wave, use high power amplifier to amplify pure sine wave to 230v), they use a more efficient method, create sine wave locked to incoming mains, convert mains into lower DC voltage, use...
