Protection Circuitry
Your new subwoofer is equipped with circuitry to provide maximum performance with greatest reliability.
The unit is protected against:
1)Overheating the amplifier.
2)Excessive drop in power line voltage.
If either of the above should happen, you should reduce the volume setting or shut the unit off until normal operating conditions return. You may also want to plug the unit into a different wall outlet, as dropping power line voltage will be most noticeable under strenuous conditions and may result in the unit shutting down intermittently.
Troubleshooting and Service
If you should experience a problem with the operation of your subwoofer, please check all of the following before seeking service. Following is a simple troubleshooting guide to assist you.
1.Verify unit is plugged in, power outlet used is active, and supplying proper voltage.
2.Is power switch on? (230V model)
3.Is unit receiving an input signal from your source?
4.Have all controls on subwoofer (volume, crossover, phase, etc.) been properly set?
5.If unit has been running at high levels for an extended period of time, one of the protection circuits may be engaged.
•Is the
•Is your power line voltage sagging below acceptable levels?
If the protection circuitry is active, the unit may cycle on and off until operating parameters return to normal. Under more serious conditions, the unit may shut off completely. Normal operation should return upon cooling, but you may be required to turn the power off and then on again to reset the unit.
