How To

Try to move the microphone closer to the sound source and adjust it for a better angle. You should also try to decrease the microphone volume to an appropriate level by turning the volume down.

Finally, try to enable the Dynamic Range Compressor (DRC) option in the QuantumEngine to lower the chance of distortion.

Finally, try to increase or decrease the microphone gain level if the sound is distorted.

Yes, this is normal for the N60NC BT. It disappears within about 20 seconds.

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.

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.

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.

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.

Yes, it will power off after removing charging cable. It is by design.

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.

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.

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.

Yes, this is a normal characteristic of this system.

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.

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.

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.

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.

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.

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.

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.

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.

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

Yes, rinse it under a faucet or under the shower, but not under full water pressure.

If you are having difficulty with the noise cancelling feature while on your PS4, please check your side tone setting in QuantumENGINE by connecting your Q800 to your PC. Please note that ANC will not work properly if the mic is on and sidetone is greater than 0. We recommend either muting the mic or change the sidetone in the JBL QuantumENGINE to 0. 

We've intentionally designed the flip-up boom mic to stay affixed to the headset. We know from experience that losing or breaking the detachable mic is never fun. Therefore, we designed the mic to fold neatly into the headset - this design also allows the mic to automatically mute when elevated. If you're wanting a detachable mic, please check out the Quantum 100 or the Quantum ONE.

Make sure the headset volume control is turned up. Rotate the volume wheel on your headset to increase the volume. If you're using the USB dongle, check that the correct playback device is selected under Control Panel > Sound > Playback. Select the proper playback device, right-click, and select "Set as Default Device". Check the computer volume levels and make sure it is not muted or turned all the way down.
