Voltage selector switch

Before switching on the power make sure the power selector switch on the rear is set to the

proper voltage. This is important. The wrong setting may damage the equipment. The crossovers

are compatible with both 50Hz and 60Hz.

Use the 115V setting where the power line voltage is 100V to 127VAC.

This is typical in USA, Canada, Central America and Japan

Use the 220V setting where the power line voltage is 220V to 240VAC.

This is typical in Europe, Africa and most of Asia.
