TROUBLESHOOTING

If there is no sound from any of
the speakers:

• Check that receiver/amplifier
is on and a source is playing.

• Review proper operation of
your receiver/amplifier.

If there is no sound coming
from one speaker:

• Check the “Balance” control
on your receiver/amplifier.

• Check all wires and connec-
tions between receiver/ampli-
fier and speakers. Make sure
all wires are connected. Make
sure none of the speaker wires
are frayed, cut, punctured or
touching each other.
In multichannel applications,
make sure that your receiver/
processor has been configured
to enable all channels that you
are using.

If there is low (or no) bass
output:

• Make sure the connections
to the “Speaker Inputs” have
the correct polarity (+ and –).
If you are using two HTI88 sub-
woofers, try inverting the polar-
ity on one subwoofer as
described on page 4.

• Consider adding a separate
power amplifier to drive the
HTI88 subwoofer.

• In Dolby* Digital or DTS

modes, make sure your
receiver/processor is correctly
configured. When using a
power amplifier with your HTI88
subwoofer, make sure the sub-
woofer output of the receiver/
processor has been enabled.
See your receiver/ processor’s
owner’s manual for further
information on correct speaker
configuration in Dolby Digital,
DTS and other surround sound
modes.

If the system plays at low
volumes but shuts off as vol-
ume is increased:

• If more than one pair of main
speakers is being used, check
the minimum-impedance
requirements of your receiver/
amplifier.
