How to measure a speaker line impedance<\/h1>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
\n
\n
\n
\n
\n

To determine the impedance of a line, the calculation is : P= U\u00b2 \/ R

\n

Therefore in 100V Line (U = 100) if an impedance (Z or R) of 100 Ohm (R = 100) was measured, the power is: 100W<\/p>\n

An impedance meter is an absolute necessity for all installers and maintainers.<\/p>\n

It helps to know the load or power of the speaker line and thus ensure that the amplifier is not overloaded.<\/p>\n

Unlike the multimeter, the impedance meter measurement is done with a sinusoidal signal.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
