Care of Your Subwoofer

Your Velodyne subwoofer does not require any regular maintenance. Normal dusting or cleaning of the surface for appearance purposes is all that is required. We suggest you avoid any harsh detergents or chemicals when cleaning the cabinet. Abrasives, detergents, or cleaning solutions may damage the finish on the cabinet. We recommend using only a damp cloth to clean the cabinet.

During normal conditions, your new subwoofer may be left on continuously without any problems. Using the Auto on/off function, the unit will automatically turn on the unit when a signal is present at the inputs and turn off after several minutes when there is no longer any signal at the inputs.

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 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 (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.

8.Is the remote non-responsive? We recommend replacing the batteries in the remote.

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
