Care of Your Subwoofer

Do not use any harsh detergents or chemicals to clean the cabinet. Abrasives, detergents, or cleaning solutions will damage the finish on the cabinet. We recommend using a damp cloth to clean the front, back and sides.

During normal conditions, the subwoofer may be left on continuously without any problems. If you plan to leave the unit unused for an extended period of time, we recommend that you turn off the subwoofer by the master power switch on the rear panel.

Troubleshooting and Service

Before seeking service for your amplifier or subwoofer, please re-check all systems. Following is a simple troubleshooting guide to assist you.

1.Verify that the unit is plugged in and power outlet used is active.

2.Is the power switch on?

3.Is the unit receiving an input signal from your source?

4.Have all controls on the amplifier (volume, crossover, phase, etc.) been properly set?

5.If the unit has been running at high levels, one of the protection circuits may be engaged. Has the amplifier overheated?

6.Has the power button been depressed on the remote?

7.Make sure binding posts are tightened.

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
