  • My JBL SB400 should turn on automatically when receiving an audio signal at either input, according to the owner's manual. However, this does not happen.
    We are sorry about this problem. EuP regulations require that electronics go into full off after some time. Unfortunately, this means that the soundbar cannot be woken up again after half an hour. It is necessary to use the ON/OFF switch.
  • My LED pairing indicator for my subwoofer has stopped to light. Is it broken?
    No, your subwoofer is not defective at all! This is normal and by design of the product after it has been paired for a longer period of time.
  • My Left Ear Piece on the JBL Free wont connect anymore, what can be done?
    There will be times that the LEFT ear will disconnect from the RIGHT or (primary) earbud. To get the Left ear to reconnect, make sure that the RIGHT earbud is on and emitting sound. Take the LEFT ear out of the charging case and put in ear. Press and hold down the power button on the LEFT ear bud for 5-8 seconds. You should hear the power on chime and then both ear buds should emit sound now. 
  • My LINK 10 or LINK 20 was lost. Can another person steal my information?
    No, since the speaker does not store any information locally. To remove all settings from your stolen device, simply unlink the speaker from your account, and the next time the speaker goes online it will not connect to your account. However, if you have used the command ""Remember this"" feature, please beware of sensitive information, as the speaker will inform you of whatever you have asked it to remember. But after unlinking the speaker, it will forget.
  • My N60NC BT has a faint whine in the right ear when I switch it on. Is that normal?
    Yes, this is normal for the N60NC BT. It disappears within about 20 seconds.
  • My new TWS earbud won't power on or charge?

    In order to get the earbuds to power on, please remove the plastic film to allow the pins in the charging case to make contact with the contact plates on the earbuds.

  • My No. 40 is not working, there is a WAITING FOR VIDEO BOX message on the front of the No. 40 Audio Processor, what do you recommend?
    First try turning power to the No. 40 OFF, disconnect then reconnect the existing comms cable between the No. 40 Audio and Video processors, and power the No. 40 ON. If this does not help try a different comms cable, this is a straight through 4 conductor cable with a 4 pin connector on each end. If replacing this cable does not help contact one of our authorized service centers for repair assistance – their contact information is under the SUPPORT tab on the Mark Levinson website.
  • My OMNI+ speaker will not connect to my Wi-Fi, is it defective?
    If your Wi-Fi network name has special characters, such as (, `, \, ', ", or ), then please change the name of your Wi-Fi network, as these characters are not supported. After changing the name, you can go ahead and setup the speaker to your Wi-Fi network.
  • My OMNI 10+, 20+ or 50+ speakers are connected to my network, but I cannot see them in the HK Controller app
    Dual band routers that have 2.4 and 5 GHz connection bands. If devices connect on different bands, they cannot see one another. Please make sure your phone and speakers are both connected to 2.4 GHz or 5 GHz and that there is no AP isolation activated between them.
  • My OMNI 50+ does not react when I am trying to pair it via Bluetooth?
    One explanation can be that your OMNI 50+ is part of a 5.1 system with your Omni Bar, which will make the surround OMNI 50+ left and right rear speakers act as "secondary", and Bluetooth connection is not possible to secondary speakers. To use the OMNI 50+ as a portable speaker again, simply perform a reset of the speaker by pressing the reset button for 5 seconds. Please note that after resetting your OMNI 50+, it is no longer part of the 5.1 wireless system.
  • my Onyx studio 2 will power off when I remove charging cable, is that normal?
    Yes, it will power off after removing charging cable. It is by design.
  • My phone charges fast up to 80% fast, then slow. Why?
    It is normal because USB-PD (USB Power Delivering) fast charging has a higher charging speed at the beginning and lower when your device soon to be full.
  • My product is not found during setup. How do I solve that?
    1. Ensure that your JBL One app device is less than 10m/33ft from the speaker during the initial set-up.
    2. Ensure it is plugged into power and the power LED is illuminated.
    3. Unplug the power cord, wait 10 seconds, reconnect the power cord and allow the speaker to power up.
    4. Temporarily relocate either the speaker or router so that they are closer together.  If the connection succeeds, the original location may be too far from the router to maintain a stable connection.
    5. Try using a different device with the JBL ONE app installed and connected to your home network.

  • My receiver does not show "DTS HD Master Audio" in the display, even though the Blu-ray disc should have this format. Instead, it just shows "DTS".
    With some Blu-ray discs, you have to go to the Settings Menu of your Blu-ray player and select "Bitstream" or "Bitstream Native". This will carry the DTS HD Master signal to be decoded in the AVR, and the AVR front panel should show the correct text.
  • My receiver makes a clicking sound when I adjust the volume. Is this normal?
    Yes, this is a normal characteristic of this system.
  • My remote control is not working. I have a credit card-sized remote with disc type battery. Do I need to replace the remote control?
    It is usually not necessary to replace an unresponsive remote control. First, check to see if there is a small plastic tab extending out of the base of the remote control. This is a protective sleeve installed on new remote controls to prevent the battery from draining. Pull this tab to remove the plastic sleeve. The sleeve must be removed before the remote will operate. If the sleeve was removed or not present and the remote control is not working then a new battery should be installed before replacing the remote control. There is a small slide out drawer that houses the battery. The battery type will be either CR2025 or CR2032 for remotes of this size. Replacement batteries are commonly available from most electronic and convenience stores that sell small batteries. Check the number on the original battery and replace it with a battery that uses the same number. These steps will typically solve the problem.
  • My SB20 is in demo mode, how can i get it back to normal?
    You might accidentally pressed volume- and surround button at the same time. This combination activate a special demo mode for the product. To stop the demo mode, either perform a full reset by holding down volume+ and surround button for 5 seconds or when power is on, press volume- and surround button again for 5 seconds.
  • My smart phone falls off of the Smartbase charging arm.
    This can be caused by dirt and dust accumulating on the charging arm, which can reduce the effectiveness of the adhesive. Clean the surface of the charging arm with a wet cloth or alcohol wipes. Do not use paper towels as these can leave paper debris.
  • My speakers can handle more power than my amplifier is putting out, yet I keep blowing them. Why is this happening?
    There are two ways to blow speakers. The first is the one we all know and understand. If you pump 500 watts into a speaker that is only rated at 100 watts, kaboom, it blows up. As a result, very few of us do this. So then why are all of these poor, helpless speakers blowing up? Because of the second reason, under-powering. It's really a misleading term, but let's try to explain. First let's take it to the maximum. Example: You have a 1000 watt speaker and a 100 watt amplifier. The way you like to listen to music requires 300 watts. Typically, you will ask your amp to put out that 300 watts that you want to hear. The amp will do it, but it will clip and distort. Unfortunately, the human ear can't hear distortion until it reaches almost 10%. By that time it's usually too late. The speaker keeps trying to reproduce this distortion that it's not capable or reproducing and eventually it blows (usually the tweeter fails first). If you are blowing speakers with an amp that has a power rating lower than your speakers, you are pushing your amp too far, causing it to clip, and blowing speakers. If you are pushing your system too hard, it is suggested that you realize your systems limitations or recommend that you get a more powerful amplifier. Please realize, if you only buy speakers that will handle more power and not a more powerful amplifier, you won't solve the problem. The speakers will still blow, because it is distortion that is blowing them, not too much power.
  • My speakers react differently, when using either battery or AC power.
    Our Control X Wireless speaker has two different patterns for switching on, when using either battery or AC power. When using battery, turning on one speaker in either stereo mode or association mode (4 speakers connected), all will turn on simultaneously, no matter which is primary or secondary. When connected to AC power, switch on the primary speaker in stereo or associated mode, and the secondary speakers will follow. If you have associated speakers stereo or 4 speakers connected, then you have to press primary speaker's power button for more than 2 seconds, then the primary will send signal to secondaries, and they will wake up. It takes approx. 30-60 seconds before all are switched on. If your press it too short (less than 2 seconds), the primary speaker will not "pair" the secondary speakers together. Switch off the primary and start over again.
  • My subwoofer is not paired with my OMNI BAR+ anymore, how come?
    Do not worry, pairing both devices is easy and quick. Press the "pairing" button on the back of the Omni Bar, then press "pairing" button on the subwoofer. They will start communicating with each other, and when both devices show white light in the LED on the back, that indicates that they are paired.
  • My telephone/tablet computer/laptop computer closes down or has a distorted screen image when placed on top of L8 or L16. Why?
    Some mobile phones, tablet computers or laptop computers will react to the powerful magnetic field from the loudspeaker drive units that are right beneath the top panel. Some have magnetic sensors built in, which means that covers with magnets in the lid can turn the phone ON when the cover lid is opened, and turn it OFF again when the lid is closed. Such phones may turn off if placed on certain portions of the top panel. Other devices are simply sensitive to magnetic fields. You can move the device around on the top of your L8 or L16 speaker, to check if some locations are better than others. The magnetic fields are most powerful near the front panel, where the speaker units are mounted. If you cannot find a location which works, your particular phone, tablet or laptop cannot be used while resting on the top panel of your speaker. There are no reports of damage to any devices because of this phenomenon.
  • My TV turns off when I'm powering off my soundbar, why?
    This is most likely due to CEC function. Some our soundbars supports CEC commands from your TV, and if some CEC commands will make the speaker react in a way you do not like, we suggest you disable all CEC functions from your TV. Please note, that your Soundbar will not turn on when your TV is turned on, due to disabling the CEC function.
  • My unit goes into standby when there is still a signal.
    Check your audio cables and make sure they are secure. Set the volume of the source device (if applicable) to a higher level.
  • My user experience is slow. How can I resolve this?
    When you are installing new apps or adding content to your LINK BAR, the system may be a bit slower when dealing with multiple things.
    Here is a couple of things you should know.
    1. You need a speedy internet connection to download all the content you added.
    2. Wait for everything to be finished, then you can enjoy the system without any issues.
    3. Reboot LINK BAR after installing all apps. A fresh reboot can help and enhance performance.
  • My wireless surround speakers are experience sound interference.

    If you find yourself encountering audio dropouts or interference coming from your surround speakers when they are not docked on the main unit, here are a couple of tips to try to remedy that.

    1. Try moving any wireless routers that are near the sound bar further away.

    2. Reboot router so it can auto select a new frequency channel, since the sound bar and router may be on the same channel resulting in audible interferences

    3. Re-position the surround speakers so they are closer to the main unit.

    4. Re-calibrate the surround speakers

    5. Adjust the volume on the sound bar and gradually raise the volume, if driven to hard the sound bar speakers can distort

  • My Xtreme got dirty after a day on the beach. Can I rinse it under the faucet or shower?
