Troubleshooting

Problem: The JBL BassQ unit does not turn on. Neither the red nor blue indicator lights are on.

Make sure the JBL BassQ processor is plugged in, and verify that there is the proper voltage at the wall outlet. Make sure the Main Power Switch on the rear panel is in the On position.

Problem: The Standby Indicator ™ lights red, but it does not change to blue when the Power Switch ¡ is depressed.

If the JBL BassQ processor is being used in a JBL Performance Series system, make sure that the surround processor is turned on, the Main Power Switch is in the On position, and there is a connection between the JBL BassQ unit’s Trigger Input Jack and another device providing a power- on voltage trigger. Please refer to the “Connecting Your JBL Performance Series System” section for reference. If the JBL BassQ unit is not being used with an AV1 or any other source pro- viding a power-on trigger voltage signal, make sure that no connection is made to the Trigger Input of the JBL BassQ processor.

Problem: There is no sound from the speakers, but the JBL BassQ unit is on (Standby Indicator ™ is lit in blue).

1.Make sure that the surround processor, amplifier or subwoofer is on, and that the correct source has been connected and selected.

2.Make sure that the correct outputs are connected from the surround processor to the JBL BassQ unit.

3.Make sure that the subwoofers are connected to the correct terminals. Check for short circuits at both ends of the speaker cables.

Problem: Not all the processors, amplifiers or subwoofers turn on in the system.

1.Make sure that all required cables are connected between system com- ponents. Refer to the “Connecting Your JBL Performance Series System” section.

2.Make sure that each component has its Main Power Switch in the On position and is set to Auto turn-on, if necessary.

3.Make sure the Power Switch ¡ on each JBL BassQ unit is in the On position (so that its Standby Indicator ™ is lit in blue when the cable is removed from its Trigger Input Jack ).

Problem: Insufficient sound output level from the speakers.

Check that the output levels of the sur- round processor or equalizer are set properly.

Problem: Insufficient bass.

Verify that the speakers have been wired to the JBL BassQ unit with the correct polarity.

Problem: Audible hum from the speakers.

1.Check the power outlets and make sure that there is a solid earth ground present. (The services of an electrician may be required.)

2.Make sure that all signal cables are routed away from power cords.

3.If these suggestions fail, experiment by running ground wires between the rear-panel screws of the JBL BassQ processors and the other system components, such as the surround processor or signal pro- cessing package.

If you still encounter difficulty after trying the suggestions above, call your JBL authorized dealer, or 516.255.4JBL (USA only) directly, for further assistance.
