CAUTION! RISK OF ELECTRIC SHOCK: DO NOT OPEN
The following table presents information on amplifier AC current consumption as well as thermal dissipation during a standard musical
program (1/8 rated output power) and during extreme heavy duty operation as could be highly compressed audio signals (1/4 rated output
power).

*Power absorption with amplifier switched off is not 0 because by EN60065/IEC 60065:2001-12 all amplifiers must have a bleeder
resistor placed across the AC mains power line in order to discharge any residual current when the amplifier is disconnected from the
mains.
