If you hear no sound at all,
check the following:
• Make sure the processor/
amplifier is plugged into a
live electrical outlet and that
the power switch is on.
• Check the connections 
from the TV or VCR to the
processor/amplifier.
• If using with a television,
make sure the TV is on and a
signal is present.
• If using with a VCR, make
sure the VCR is playing 
a tape.
• Check all connections
between processor/amplifier
and each of the speakers.

If one or more of the 
speakers does not play,
check the following:
• Check all connections
between processor/amplifier
and each of the speakers.
• Adjust the balance controls
from left to right and front 
to rear.

If you have very little 
bass output, check the 
following:
• Make sure the subwoofer is
connected properly to the
processor/amplifier.
• Experiment with placement
of the subwoofer. Remember,
place the subwoofer in a cor-
ner to get maximum bass out-
put from the system.
• Make sure “Bass Boost” 
is on.
• Adjust “Bass” level.

If there is no sound coming
from the rear speakers or
the volume is very low,
check the following:
• Check all connections
between processor/amplifier
and each of the speakers.
• Adjust the front-rear 
balance controls on the
processor/amplifier.
• Make sure the TV show or
movie you are watching is
recorded in Dolby* Surround.
If it is not, try the “Concert
Hall” or “Stereo” settings on
the processor/amplifier.
