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?

3.Is auto turn on/off set properly?

4.Is unit receiving an input signal from your source?

5.Have all controls on subwoofer (volume, crossover, phase, etc.) been properly set?

6.If unit has been running at high levels for an extended period of time, one of the protection circuits may be engaged.

Is the built-in amplifier extremely hot to the touch?

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.

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 cabinet or circuitry is physically damaged.
