The heat power can b e calculated as in the following example:
We consider a headroom of at least 5dB (1/3 of full power) and a
producing 700 watts per channel. The 1/3 power per channel is accordingly 700 / 3 = 233.5 watts, and
total output 2 x 233.5 = 467 watts.
The power consumption according
power consumption of the amplifier with different loads and power levels.
T he heat power produced is the difference between the power consumption and output power:
1150 - 467 = 683 watts per amplifier.
The chart below shows the heat power

note 1 Average power with music as program source. The amplifier driven to clip level.
note 2 Normal music power with 9dB headroom, IEC standard power rating.
T he efficiency can also be calculated, it being the output-power divided by the input-power:
467 watts / 1150 watts= 41%.
