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

*1) The amplifier section’s PSU operates as a non-resistive load, so the calculation “Volts x Amps = Watts” would not be correct. Instead, measured and
specified here is what is known as the “Active Power” of the amplifier section providing useful, real-world values of power consumption and heat dissipation.
*2) Current draw figures measured at 230 V. 115 V figures are converted from 230 V figures.
*3) Figures measured at maximum power before amplifier protection and limiter features are engaged. Typically this is between 1/4 and 1/3 of rated power.
Note that the maximum power condition is very extreme and will not occur during normal operation. Also note that the mains breaker will not be tripped
even if operation is in excess of maximum ratings.
