If there is no sound from any
of the speakers:

plugged into an active AC
wall outlet.

Switch, located on the rear of
the subwoofer, is in the
On/Standby position.
• Make sure there is a source –
for example, a DVD Player, CD
Player, VCR or television –
hooked up to one of the four
input jacks.
• Make sure that the program
material is playing.
• Recheck the hookup
connections, referring to the
Speaker Connections section.
If there is no sound from the
surround speakers or
sound is very low:
• Check all connections
between processor/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

Pro Logic Surround. If it is
not, try the Phantom or
Simulated Surround mode.
• Increase the surround-
speakers’ level, using the
level-adjustment instructions
found earlier in this manual.
If there is no sound from the
center speaker:

center channel, using the
level-adjustment instructions
earlier in this manual.
• Check the connections
between the subwoofer and
the center speaker.
If you have low bass output:
• Experiment with placement
of the subwoofer. Remember,
place the subwoofer in a
corner to get maximum bass
output from the system.

using the level-adjustment
instructions found earlier in
this manual.
