4.1.2 Checking speaker systems
1. A drawing of the system should be made before testing so the measurement can be
attributed to network.
2. By example, the following setup shows a speaker system of 260 W using a 100 V
voltage line.
Z = V
3. Estimated impedance value should be:
4. If Z measured is lower, check for short circuited wires or faulty speakers or
transformers.
5. If Z measured is higher, check for wiring or components (speakers, transformers or
connections).
