Constant voltage line
In order to get a constant voltage line (25 V, 70 V, 100 V) connect one of the speaker/transformer lines to
the COM terminal and the other to the terminal bearing the voltage value that you need.
− − − − The speakers need a transformer with an input voltage equal to the input voltage provided by the
amplifier.
− − − − The sum of the speakers power should not be higher than the maximum amplifier output power.
