Troubleshooting

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.
