The PA1000 consists of two field-replacable power modules with two amplifiers in
each module. Each of the paralleled amplifiers is protected by a 10 ampere
fast-acting fuse. When a fuse opens, the indicator light next to it illuminates.
Fuses 3 and 4 represent amplifiers 1 and 2 on the top right module. Fuses 7 and 8
represent amplifiers 3 and 4 on the lower right power module.
