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.
4. Four screws are provided, two for securing speaker to the back box and two for aesthetics. The two non-functional screws will be held in place by the pressure fit of the faceplate.
