Alesis CLX440 Reference Manual page 21

Do not operate any electrical equipment with ungrounded
outlets. Plugging the CLX-440 into an ungrounded outlet, or
"lifting" the unit off ground with a three-to-two wire adapter,
can create a hazardous condition. Alesis cannot be responsible
for problems caused by using the CLX-440 or any associated
equipment with improper AC wiring.
To use the CLX-440 in another country:
The CLX-440 has what's called a "switching power supply". That
means it works with any AC voltage from 90 to 250 volts, 50 to
60 Hz. This eliminates the need for transformers or voltage
switches when you travel from country to country. Your CLX-
440 was supplied with the correct power cord for your country
or local area. If you plan to travel with it to another country,
obtain an IEC-spec AC power cable compatible with the outlets
used in the other country and use it in place of the supplied
cable. The following alternative power cords are approved for
use with it:
• For 100-120 VAC 50/60 Hz operation in the US, Canada
and/or Japan, use Alesis UL/CSA power cord #7-41-0001.
• For 230 VAC 50 Hz operation in England, use Alesis Power
cord #7-41-0004.
• For 220 VAC 50 Hz operation in Europe and Scandinavia,
use Alesis EU power cord #7-41-0002.
• For 230 VAC 50 Hz operation in Australia, use Alesis AS
power cord #7-41-0003.
Do you hear an AC hum in your system? For detailed tips
on how to get rid of "ground loops" that cause hum, see page
