*1) The amplifi er’s PSU operates as a non-resistive load, so the calculation “Volts x Amps = Watts” would not be correct. Instead, measured and
specifi ed here is what is known as the “Active Power” in the amplifi er providing useful, real-world values of power consumption and heat dissipation.
*2) Current draw fi gures measured at 230 V. 115 V fi gures are 230 V fi gures multiplied by two.
*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.
