Specifications

(2) Voltage Range
The APL-220, -500, and -800 use advanced, intelligent power supplies
designed with built-in Power Factor Correction (PFC) and Universal Line
Voltage (ULV) capability. The power supply will function properly with line
voltages ranging from 88V AC to 275V AC; there is no need to make any
adjustments to the unit for use virtually anywhere in the world. If the line
voltage falls below 88V AC, only a loss of power output capability will occur.
Sustained use below 88V AC is not recommended and may cause the ampli-
fier power supply to overheat and engage thermal protective shutdown. In
addition, the amplifier may not start up with voltages below 88V AC.
If the line voltage exceeds 275V AC, damage to the unit is possible.To avoid
damage, voltages above 275V AC and below 88VAC should be avoided at all
times!
(3) Current Requirements
All power amplifiers require sufficient current for proper operation and the
amplifiers designed into Apogee powered loudspeakers are no exception.
Chart #1 shows the required current for one APL-220, -500, and -800 at
three standard international working voltages (100, 120, & 240V AC).
Because current drain is ultimately a function of the program source, Chart
