Mains Operation And Leakage Power
The mains power consumption as well as the leakage power is stated for driving the power amplier 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.
