Troubleshooting

The HRSIW8 subwoofer is designed and built to provide years of trouble-free performance. Most problems that occur can usually be solved by checking your setup, or by making sure all components are fully operational.

The following information will help you deal with common problems you may experience. If a problem persists, please contact your Dealer for assistance.

Poor or no sound

•Check all the connections from the subwoofer to the amplifier.

•The speaker is designed to be powered only by the Sunfire HRSIW8 amplifier. No other amplifier should be used as the perfomance will suffer, and possible damage to the speaker will occur.

•Check that the amplifier is not driven too hard.

•Many processor/preamps can send test tones through all the loudspeakers in your system. Use this to adjust the volume of each channel until they are all playing at the same level. Make sure that any bass management options are set correctly.

•If the system bass is weak only when playing surround sources, check that your processor is correctly set to decode the surround modes, such as Dolby Digital or DTS.

•Some DVD discs have a menu that allows you to select which soundtrack to play. Check that the correct surround audio soundtrack is selected.
