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 (1/4 rated power).

*1) The amplifier’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” in the amplifier providing useful, real-world values of power consumption and heat dissipation.
*2) Current draw figures measured at 230 V. 115 V figures are 230 V figures multiplied by two.
*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 max. 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 max. ratings.
