6 Mains Voltage Selection
The CPA240 amplifier is provided with a mains voltage selector.
This selector allows the amplifier to produce optimum power output without the risk of over
temperature shutdown due to excessive heat dissipation.
Note: It is critical that the mains voltage selector is adjusted to the correct setting.

If the voltage selector is incorrectly set the amplifier may shutdown due to excessive
heat dissipation or even be permanently damaged. Therefore it is crucial that the selector
is set correctly.
