The amplifier is a variable voltage equipment that can run
on 100V, 117V, 220V or 240V power supply. Your unit
comes already preset at the proper voltage for use in your
area; however, if you move to an area where the power
supply voltage is different, the voltage setting can be
manually changed. BE SURE THAT YOUR UNIT IS
NOT CONNECTED TO THE POWER SOURCE BEFORE
ATTEMPTING TO MAKE THIS CHANGE.

To change the voltage setting, remove the name plate on
the rear panel and locate the VOLTAGE SELECTOR (see
figure below). Pull up the Voltage Selector plug which
has a white arrow on its top. Reinsert the Plug to the
Selector Base so that the head of the arrow lines up with
the pointer line of the voltage you desire.
