USING COMPONENTS WITH DIFFERENT VOLTAGES
Sometimes it may be practical to use a transformer or loudspeaker/transformer combination with a different voltage system from what it was originally intended. For example, a
To properly derate the transformer tap power levels, locate the column with the voltage the transformer is rated for in the table below, then locate the row with the system voltage you want to use it in. The table will indicate the dB reduction to use with the derating chart below it.
EXAMPLE
You have a
The table shows that 50 volts is 3 dB less than 70 volts. The chart confirms that the taps will provide 0.3, 0.6, 1.25, and 2.5 watts, respectively.
