4.2 Power requirements estimation

1. At speaker systems, when the type of line is knows, generally 100 V, 70 V or 50 V,
as well as the impedance, then it is possible to calculate the power requirements:
Knowing that:
For example on a 100V system, if Z measured is 200 Ω:
So, knowing the required power value allows to choice a suitable amplifier.
