Troubleshooting
The Cinema Ribbon CRW loudspeak-
ers are 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
loudspeaker to the amplifier or receiver.
Swap loudspeakers around, and see
if the poor sound follows a particular
loudspeaker.
• Check that your amplifier is not driven
too hard or is clipping. Even a low-pow-
ered amp driven into clipping can cause
distortion or damage your loudspeakers.
• 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, and any channels using
the Cinema Ribbon loudspeakers are
set to "small."
• 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.
