How to measure a speaker line impedance
Therefore in 100V Line (U = 100) if an impedance (Z or R) of 100 Ohm (R = 100) was measured, the power is: 100W
An impedance meter is an absolute necessity for all installers and maintainers.
It helps to know the load or power of the speaker line and thus ensure that the amplifier is not overloaded.
Unlike the multimeter, the impedance meter measurement is done with a sinusoidal signal.
