If there is no sound from any
of the speakers, check the
following:
• Make sure the subwoofer is
plugged into an active AC wall
outlet.
• Make sure the Master Power
Switch, located on the rear of the
subwoofer, is in the
“ On/Standby ”
position.
• Make sure there is a source –
for example, a VCR or television –
hooked up to the TV or tape/aux
input jacks on The Source.
• Make sure that the program
material is playing.
• Recheck the hookup connec-
tions.
If most of the sound comes from
the center-channel speaker, with
little or no information from
the surround channels, note the
following:
Although most of today’s televi-
sions are equipped with stereo
audio output jacks, some stereo
televisions have poor audio sec-
tions and are unable to provide a
Dolby Pro Logic encoded signal. In
the unlikely event that you experi-
ence this problem, connecting the
audio outputs from your hi-fi VCR,
laser disc player, DVD player, or
satellite receiver directly to one of
the inputs on The Source will pro-
vide a proper audio signal and
allow you to enjoy true Dolby Pro
Logic surround sound.
If there is no sound from the
surround speakers or sound is
very low, check the following:
• Check all connections between
the amplifier and each of the
speakers.
• Raise the surround volume
from the remote control
(see
“ Operation ” section).
• Make sure the TV show or movie
you are watching is recorded in
Dolby Surround.
If there is no sound from the
center speaker, check the
following:
• Make sure that the processor
is in the Pro Logic mode. If it is
in Phantom or Stereo mode, the
center speaker will not play.
• Check the connections between
the subwoofer and the center
speaker.
If you have low bass output,
check the following:
• Experiment with placement of
the subwoofer. Remember, place
the subwoofer in a corner to get
maximum bass output from the
system.
• Increase the level of bass,
using the remote control.
• Adjust the level control on the
rear of the subwoofer.
If you are having trouble picking
up radio stations, check the
following:
• Make sure the antenna is
hooked up properly.
• Depending on your distance from
the station’s transmitter, you may
need to install an FM antenna on
the roof or in the attic.
