Litt om prinsippet TVC / Transformer Volume Control:

Instead of relying on resistive potentiometers, this type uses a transformer to attenuate the signal. A potentiometer, even a fancy stepped one, will attenuate the signal by turning most of it into heat and passing on the rest. A transformer on the other hand will not waste any energy, except for some minor losses. The voltage will be lowered, but it will be traded for current. Basically, this means that the impedance match between source and power amp will be improved, instead of worsened, as long as you attenuate the signal. And in almost all cases the signal will be attenuated, making this a solution that has some serious theoretical advantages over the classic resistive passive preamp.
