Current Draw and Thermal Dissipation specification

The following tables contain information on measured current consumption as well as calculated heat dissipa-
tion during normal operation(1/8 rated power); and during extreme heavy duty operation (1/4 rated power).

*1) 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.
*2) Current draw gures measured at 230 V. 115 V gures are 230 V gures multiplied by two.
