To calculate the amplifiers capability:
If your chosen amplifier has a maximum output of
120 Watts at 100V, the minimum impedance connected should be at least 83 Ohms (100V x 100V/120W).
Use a professional impedance meter, not a Multimeter.
INSTALLATION
How to Calculate the correct load for a 100V Amplifier:
When installing a 100V loudspeaker system it is rather simple to calculate the number of loudspeakers that
can be connected to a particular 100V amplifier.
Each 100V loudspeaker has a 100V transformer that will have different power tappings, for example 1.5, 3
and 6W. The sum of all taps should never exceed the amplifiers power rating.
