*The amplier’s PSU operates as a non-resistive load, so the calculation “Volts x Amps = Watts” would not be correct. Instead, measured and specied here is what is
known as the “Active Power” in the amplier providing useful, real-world values of power consumption and heat dissipation.
The following tables contain information on measured current consumption as well as calculated heat dissipation during what we see as the most
extreme sustained normal operation (1/8 rated power).
