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.
