TROUBLESHOOTING

The vast majority of new speaker “malfunctions” end up being traced to connections or switch settings. Check the following tips first, before request- ing service.

No sound at all or very faint sound from both speakers

1.Amp/receiver tape monitor button pushed in while using CD, FM or phono inputs.

2.Wrong speaker switch, “A” or “B” speaker output.

3.Sound source (CD, cassette deck, turntable) not turned on, not activated, not hooked up or not selected on amp/receiver front panel.

No sound from one speaker

1. Balance control turned all the way left or right.

2. Speaker wire has become disconnected.

Both speakers play at low volume but shut off as volume is increased OR sound turns on and off intermittently

A few strands of speaker wire may be shorting out. Recheck the connections. Recheck the impedance requirements of the amp.

Bass is very weak AND/OR sound seems to come from each speaker separately, without creating a stable stereo image between the speakers.

1. The polarity (+&–) of one speaker has been reversed relative to the other. Double check connections.

2. Speakers are too far away from back and side walls or too far apart. Experiment again with the speaker placement. If you are still experi- encing problems, consult your JBL dealer.

GENERAL CARE

The grille is held in place by pins near the edges (except G40, which has a non-removable grille). To remove the grille, grasp it by both top and bottom edges and pull gently. To replace grille, reposition it carefully and press gently at the corners. Do not push on the center area of the grille.

The loudspeaker cabinet may be cleaned with a slightly damp cloth. To remove dust from the grille cloth, use a vacuum with a brush attachment. Spots may be removed with a commercial spot remover. Do not use any cleaners or solvents on the speaker drivers themselves.

SERVICE

Should your loudspeaker ever need service, return it to the JBL dealer from whom it was purchased. If for some reason this is impractical, call 800-336-4JBL for your nearest warranty station. Do not return products to the JBL factory without prior authorization.

Another technology that sets the G Series apart is its sophisticated crossover networks. These networks are crucial for managing how audio signals are distributed among the different drivers. JBL engineers meticulously design these crossovers to ensure seamless integration between components, resulting in a cohesive and dynamic sound reproduction.

Connectivity options in the G Series are also user-friendly, offering a range of inputs and outputs that cater to various setups. Whether you're connecting via XLR, TRS or other formats, the versatility in connectivity ensures compatibility with a wide range of audio equipment.
