Q Series Operation Manual
8.5 BTu specifications
The following tables contain information on measured current consumption as well as calculated heat dissipation
at three states: 1) Stand-by/idling; 2) Normal operation (1/8 of rated power); and 3) at extreme heavy duty
operation (Max. power).

*2) Current draw figures measured at 230 V. 115 V figures are 230 V figures multiplied by two.
*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.
*3) Figures measured at maximum power before amplifier protection and limiter features kicks in. Typically this is between 1/4 and 1/3 of rated
power. Note that the max. power condition is very extreme and will never occour during normal operation. Also note that the mains breaker will
not be tripped even it's in excess of max. ratings.
