11.4 Current Draw and Thermal Dissipation specifications

Table 11.4 contains data on measured current consumption and calculated heat dissipation for four operating
conditions: i) Power on, no signal; ii) Normal operation (1/8 of rated power); iii) Heavy duty operation (1/4 rated
power – see Note 3 at foot of table); iv) 20 kHz sine wave.

*1) The amplifi er section'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" of the amplifi er section 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 converted from 230 V fi gures.
*3) Figures measured at maximum power before amplifi er protection and limiter features are engaged. Typically this is between 1/4 and 1/3 of rated
power. Note that the maximum 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 maximum ratings.
