Mains Operation And Leakage Power

The mains power consumption as well as the leakage power is stated for driving the power amplifier at different levels. All the values were measured at nominal load via the 100 V output with two channels driven. The shown values differ only slightly when the appliance is operated at different nominal output voltages or in the Direct Out mode.
