JBL ESC333 setup guide Troubleshooting, If you have low bass output

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 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 Digital or 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:

•Make sure that the processor is in the Surround or

3-Stereo mode. If it is in Phantom or Stereo mode, the center speaker will not play.

•Increase the level of the 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.

•Increase the subwoofer level, using the level-adjustment instructions found earlier in this manual.

•Increase the level of bass, using the remote control.
