Troubleshooting - Proficient Protege F5 Series Owner's Manual

SUBWOOFER CARE
To maintain the subwoofer cabinet's finish, unplug the power cord and then use a soft cloth to clean the
surfaces. If your subwoofer needs servicing, please read the troubleshooting section below.

TROUBLESHOOTING

The Proficient Protege FS Series Subwoofers have 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 components connected to the amplifier are on and fully operational. The following information will
help you deal with common problems you may experience during normal use.
If a problem persists, please contact your authorized Proficient dealer or Proficient Customer Service at
800.472.5555.
Not Enough Bass
• Check that your receiver'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 function.
• If your receiver has a single subwoofer/LFE output jack, make sure it is connected to the subwoofer's Left
input. If the bass is still not heavy enough after checking all the remaining points, use a Y cable to connect
the receiver's single subwoofer/LFE output to the subwoofer's left and right inputs.
• Try moving the subwoofer to a different location. See Subwoofer Placement on Page 3. While not absolutely
essential, placing the subwoofer in a corner location will maximize the bass output and give the smoothest
possible response.
• Home Theater receivers 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 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 receiver'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 7.1 or 5.1 Surround System
• 7.1 and 5.1 Home Theater receivers usually have a bass management system that allows the bass to be
redirected among your speakers. For example, the bass normally present in the front speakers can be
redirected to play in the subwoofer, or the subwoofer can play the bass from all the speakers, in addition
to its dedicated LFE (low frequency effects) channel. Make sure that all of the bass management options are
correctly set. The processor may have a way of turning the subwoofer output off entirely, so check that it is
always on.
