To calculate the ampliers capability:
If your chosen amplier has a maximum output of 30 Watts at 100V,
the minimum impedance connected should be at least 333 Ohm (100V x 100V/333 Ohm = 30W).
When measuring a constant voltage speaker load, use a professional impedance meter, not a multimeter.
INSTALLATION
How to Calculate the correct load for a 100V Amplier:
When installing a 100V loudspeaker system, it is rather simple to calculate the number of loudspeakers that
can be connected to a particular 100V amplier.
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 ampliers power rating.
