Sunfire HRS-12, HRS-8, HRS-10 user manual Troubleshooting, Not enough bass in a 5.1 system

Troubleshooting

This subwoofer has been 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 that the compo- nents connected to the amplifier are on and fully operational.

The following information will help you deal with common problems you may ex- perience during normal use. If a problem persists, please contact your Dealer for assistance.

Not enough bass

•Check that your processor’s outputs are connected to the subwoofer’s line-level inputs and not to the line-level high pass outputs. If they are connected to the outputs by mistake, the bass will be weak but the subwoofer will still func- tion.

•If your processor has a single sub- woofer/LFE output jack, make sure it connects to the subwoofer’s Left input. If the bass is still not enough after checking all the remaining points, use a Y cable to connect the processor’s single subwoofer/LFE output to the subwoofer’s left and right inputs.

•Try moving the subwoofer to a different location. See Location on page 10. Placing it in a corner will maximize the bass output and give the smoothest possible response.

•Home Theater processors usually have a way of adjusting the level of the subwoofer/LFE output, either using a remote control or with a small volume knob on the back panel. Make sure that this is adjusted correctly.

•Check that your processor or receiver’s sub output is turned on. Some systems only have a sub output signal when the front speakers are set to “small.”

•If the processor’s Sub/LFE output has an adjustable crossover frequency, make sure that the subwoofer’s own crossover point is set to Bypass or part of the bass range may be missing.

Not enough bass in a 5.1 system

•5.1 Home Theater processors usually have a bass management system which allows the bass to be redirected among your speakers. For example, the bass normally present in the front speak- ers can be redirected to play in the subwoofer, or the subwoofer can play the bass from all the speakers, in addi- tion to its dedicated LFE (low frequency effects) channel. Make sure that all of the bass management options are cor- rectly set. The processor may have a way of turning the subwoofer output off entirely, so check that it is always on.

•Check that the processor calibration procedure is correctly adjusted. Usually, the preamp will send a test tone through all the speakers in your system, allowing you to adjust (trim) the volume of each channel until they are all playing at the same level.

•If the bass is weak only when playing

5.1surround sources, check that your processor is correctly set to decode the

5.1surround modes, such as Dolby Digital or DTS.

•Some DVD discs have a menu which allows you to select which soundtrack to play. Check that the correct 5.1 surround audio soundtrack is selected, otherwise it may just play stereo into your preamp and you won’t get the true LFE signal into the subwoofer.
