Troubleshooting
If there is no sound from any
of the speakers:
• 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 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

• Raise the surround volume
from the remote control (see
Operation section).
• Make sure the TV show or
movie you are watching is
recorded in surround, try the
