How to troubleshoot jbl creature speakers
The JBL Creature line of speakers consist of a powered nondirectional subwoofer and two satellite speakers. They can be connected to computers, MP3 players and other devices with audio out capabilities. The subwoofer unit serves as the control centre of the speaker system.
The speakers, audio line and power all run to the subwoofer. The subwoofer also handles the bass/treble settings. Troubleshoot these particular speakers in multiple ways if there is no sound, low sound or distorted sound.
Check that the system is getting power and turned on. Verify that the power supply is connected to a working outlet or power strip. Locate the power button on the back of the subwoofer next to the speaker ports and push it in. You will see a green light glowing on the back of the subwoofer, confirming power.
Look at the speakers themselves. If one or both of the speakers' green lights are off, a connection problem may be present. Look at the back of the subwoofer and the different ports. Note that each port is a different colour.
Verify that the correct speaker is plugged into the correct port. The end of each speaker wire has a coloured plug, and the tip is a shape, such as a triangle or square. Plug the matching colour and shape into the associated port on the back of the subwoofer. Check to make sure the connection is secure. You may need to rotate the jack to ensure the shaped connection is fully in place.
Check the lights on the speakers. If both lights are on, the connection is correct. If there is still no sound, proceed to Step 5.
Check that the Audio Out cable is firmly in place on the Audio Out port on the back of the subwoofer. Trace the wire to the computer's Audio In line and verify that it is connected.
Tap the "Volume Up" or "Volume Down" button on the right speaker lightly. Tapping both at the same time mutes the speakers; tapping one button will unmute it. If the volume was too low, this will also bring the volume levels up.
Adjust the "Bass" and "Treble" knobs on the front of the subwoofer if either settings are too high or too low. This will correct issues such as too much bass, too little bass or treble issues.
Push the power button on the back of the subwoofer to turn off the unit. Unplug the unit from the power supply and wait a few minutes. Reconnect the power and turn the unit back on. Lightly tap the "Volume Up" button on the right speaker until you hear sound.
- Check your computer's volume settings to ensure the sound card is not muted. Verify something with audio is playing on the computer to hear the sounds.
