The impedance test supports the verification of distributed loudspeaker installations and shows detailed information of the connected load. The test result shows if the connected speaker system is in good order as well as the required amplifier power ratio. The power is automatically calculated by the measured impedance for 25 V, 35 V, 50 V, 70.7 V, 100 V, 140 V, 200 V systems.
The FX100 Audio Analyzer, together with the 100 V RT-IB Impedance Test Box, allows to acquire the impedance response of virtually all loudspeaker types, including distributed audio 70 V / 100 V loudspeaker systems.
The tests are executed with a logarithmically swept Glide-Sweep. This technology ensures very fast, yet precise measurement results.
