Troubleshooting
The Cinema Ribbon loudspeakers are
designed and built to provide years of
trou ble-free per for mance. Most prob-
lems that occur can usually be solved by
checking your setup, or by making sure
all com po nents are fully op er a tion al.
The following information will help you
deal with common problems you may ex-
pe ri ence during normal use. If a problem
persists, please contact your Dealer for
assistance.
Poor or no sound
• Check all the connections from the
loudspeaker to the amplifi er or receiver.
Swap loudspeakers around, and see
if the poor sound follows a particular
loudspeaker.
• Check that your amplifi er is not driven
too hard or is clipping. Even a low-pow-
ered amp driven into clipping can cause
distortion or damage to your loudspeak-
ers.
• Many processor/preamps can send
test tones through all the loudspeakers
in your system. Use this to adjust the
volume of each chan nel until they are
all playing at the same level. Make sure
that any bass man age ment options are
set correctly, and any channels using
the Cinema Ribbons 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 sur round 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.
