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 video or auxiliary input

jacks.

• Make sure that the program

material is playing.

• Recheck the hookup con-

nections in the ”Speaker

Connections“ section.

If there is no sound from

the surround speakers or

it is very low, check the

following:

• 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

recorded in Dolby Surround.

If it is not, try the Phantom

or Simulated surround mode.

If there is no sound from

the center speaker, check

the following:

• Make sure that the proces-

sor is in the Pro Logic,

3 Stereo, or Simulated 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.
