What to do if JBL speaker won't turn on?
If your JBL speaker is connected to working AC power but won't turn on, the power cable might be faulty or improperly connected. Try re-seating the power cable at both ends or substitute it with a known-good power cable. If that doesn't work, the fuse may have blown, but there are no user-serviceable fuses, so take your speaker to a competent servicer.
Why does my JBL speaker have no sound but it comes on?
If your JBL speaker comes on but produces no sound, the signal source (mixer, instrument, etc.) might not be sending a signal. Check the VU meters on the source mixer, verify that the tape or CD is playing, and use headphones to confirm that the instrument is sending an audio signal. Faulty cables and connections can also cause this issue, so disconnect and re-seat signal cables or replace suspected cables with known-good ones.
What to do if my JBL EON15 sound distorted and loud?
If your JBL speakers are producing a distorted and very loud sound, and the PEAK light is frequently on, it means the input signal is too high and exceeding the speaker's capabilities. Try reducing the output level from your source, lowering the level controls on the speaker, or using additional JBL EON speakers.
Why do my JBL EON15 hum or buzz when I move the mixer level controls?
If you're experiencing hum or buzz that changes when you adjust the mixer levels on your JBL speakers, it could be due to an improper A/C ground or faulty equipment connected to the mixer input. Try disconnecting or muting channels one at a time to identify the problem. Also, a faulty cable between the source equipment and mixer can cause this issue, so try substituting it with a known-good cable.
How to stop JBL EON15 Speakers from feeding back?
If your JBL speakers are feeding back and howling when the microphone volume is turned up, it could be due to several reasons. First, ensure the microphones are not pointed directly into the speakers' pickup pattern. Also, incorrect equalizer settings can cause feedback, so locate the feedback frequency and reduce it using the mixer EQ or an external equalizer. Finally, excessive gain can be a culprit, so reduce the gain at the mixer and move the microphone closer to the sound source.
Why do my JBL speakers have a hum or buzz?
If you're experiencing hum or buzz with your JBL speakers, it could be due to improper A/C grounding or ground loops. Try using an XLR/F to XLR/M adapter on one end to 'telescope' the audio ground, and re-route audio cables away from AC power and lighting cables. Excessively long unbalanced cable runs or improper system gain structure can also cause this; try using the balanced outputs of your mixer or source equipment, or a DI box to convert unbalanced output to balanced. Reducing the INPUT 1, 2, and 3 controls while increasing the output level of your source devices may also help.
Why do my JBL EON15 Speakers have a lot of hiss?
If your JBL speakers have a lot of hiss in the sound, even with the mixer controls at very low settings, it might be due to improper gain structure. Make sure that the MIC/LINE switch is in the LINE (disengaged) position. Reduce the level settings at the speaker. Also, review the owner’s manual for your mixer and adjust controls as needed, paying attention to input sensitivity (gain), channel faders, and master faders.
Why do my JBL EON15 sound distorted at moderate volumes?
If you're experiencing distorted sound from your JBL speakers even at moderate volumes, and the PEAK light is not lit, the mixer or other source might be overdriven. Review the owner’s manual for your mixer and adjust controls as needed, paying attention to input sensitivity (gain), channel faders, and master faders. Then, review the instructions in the Quick Start section of the guide.
Why is there no sound with microphone connected to JBL speaker?
If you're not getting any sound when connecting a microphone directly to the MIC/LINE 1 input on your JBL EON15 G2 speaker, it might be because the microphone requires phantom power, which the EON15 G2 does not supply. Switch to a dynamic microphone, use a battery in the microphone (if possible), or use an external phantom power supply.
Why is there noise or hiss coming from my JBL speaker?
If you hear noise or hiss at the output of your JBL speaker, it could be due to a noisy source device. Disconnect the devices connected to your speaker one at a time. If the noise goes away, the problem is with the source or the connecting cable.
