6.5.1Calculation

The current draw can be calculated by dividing the mains input power by the mains voltage.

We recommend that you design the power distribution for at least the required current at 1/8 power, or 1/3 power for heavy-duty demands such as concert touring and Industrial music etc.

The heat power can be calculated as following:

If a headroom figure of at least 5dB (1/3 full power) is used with a 4 ohms load on all four channels of the amplifier.The 1/3 power per channel is then; 200 / 3 = 67 watts, and total output power is; 4 x 67 = 267 watts.

The mains power consumption from the chart above is 720 watts.

The heat power produced is the difference between the power consumption and output power; 720 - 267 = 453 watts total for the amplifier.
