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
Before seeking service for your amplifier or subwoofer, please
1.Verify that the unit is plugged in and power outlet used is active.
2.Is the unit receiving an input signal from your receiver or processor?
3.Have all controls (volume, crossover, phase, etc.) been properly set?
4.If the unit has been running at high levels, one of the protection circuits may be engaged. Has the amplifier overheated?
5.Make sure
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.
The following conditions require service by a qualified technician:
1.The power cord has become damaged.
2.The unit does not appear to operate normally or exhibits a marked change in performance.
3.The unit has been exposed to water.
4.Some part of the chassis or circuitry is physically damaged.
