*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.
