*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 sustainable power without tripping the mains fuse. Listed separately for 30 A/115 V and 16 A/230 V operation. 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 momentarily in excess of max. ratings.
*4) Italics used for conditions that, if sustained over long time periods, may trigger the mains breaker. Therefore these measurements should not be used
when calculating cooling requirements as they cannot be sustained by the mains breaker over time.
