TROUBLESHOOTING

If there is no sound

from any of the

speakers:

• Check that receiver/amplifier

is on and a source is playing.

• Check all wires and connections

between receiver/amplifier and

speakers. Make sure all wires

are connected. Make sure none

of the speaker wires are frayed,

cut, punctured or touching each

other.

• 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/amplifier

and speakers. Make sure all

wires are connected. Make sure

none of the speaker wires are

frayed, cut, punctured or touch-

ing 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 subwoofers,

try inverting the polarity 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/proces-

sor is correctly configured. When

using a power amplifier with your

HTI88 subwoofer, make sure

the subwoofer 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 volume is

increased:

• Check all wires and connec-

tions between receiver/amplifier

and speakers. Make sure all

wires are connected. Make sure

none of the speaker wires are

frayed, cut, punctured or touch-

ing each other.

• If more than one pair of main

speakers is being used, check the

minimum-impedance require-

ments of your receiver/amplifier.
