CONNECTIONS
Use the supplied stereo audio cable to connect the
soundbar's Source 1 (analog) input to your TV's stereo audio output.
If your TV has two sets of audio output jacks, use the set that has
a fixed (not variable) output level. This will let you turn your TV's
speakers all the way off while the TV still supplies a constant audio
signal to the soundbar.
If your DVD player, cable tuner or satellite tuner has an optical
digital output, you can use an optical digital audio cable to connect it
to the soundbar's Source 2 (optical digital) input.

NOTE: If your DVD player, cable tuner or satellite tuner does not have
an optical digital output, you can connect its analog audio output to
your TV. The TV will send its audio signal to the soundbar through the
analog connection described above.
After verifying that all of the source connections have been made
properly, plug the supplied power cords into the soundbar's and
subwoofer's Power Cord connectors, and plug the other ends into
active, unswitched AC outlets. Do NOT plug these cords into the
accessory outlets found on some audio components.
