System Considerations
1. To select the proper wattage input for the speaker, move the jumper
to the appropriate pin.
2. Always maintain electrical isolation between speaker and strobe
wiring on combination units.
3. Do not exceed 130% of rated speaker voltage. If excessive distortion
is heard, check amplifier for signal clipping. If clipping exists, reduce
either amplifier input or gain.
