Do not operate any electrical equipment with ungrounded outlets. Plugging the PEQ-450 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 PEQ-450 or any associated equipment with improper AC wiring.

To use the PEQ-450 in another country:

The PEQ-450 has what's called a "switching power supply". That means it works with any AC voltage from 100 to 230 volts, 50 to 60 Hz. This eliminates the need for transformers or voltage switches when you travel from country to country. Your PEQ-450 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 32.
