How To

There is a known issue that Spotify Connect and Amazon Music are not stable over a wired connection. If you primarily use these services, it is recommend to connect to the home network via Wi-Fi.

When not connected to AC power, the speaker will be automatically switch off after 1 hour of inactivity to save battery consumption. You can adjust the auto standby time on JBL One app.

This speaker has an auto calibration feature, which measures the space around the speaker and adjusts the sound quality based on the room around it. Auto calibration will automatically work when you power on the speaker and begin playing music. For the best sound, we recommend placing the speaker at least 18 inches (0.5 meters) away from any walls.

Orange cable is JBL signature color!

Vehicles that have an Active Noise Cancelling system are prone to encounter sound issues when an after-market subwoofer is installed. The sound issue can be described as a hum or low-frequency tone. To understand why this is happening it's important to understand how the ANC system in a vehicle works.

 

The ANC system's main job is to pick up on any internal/external low-frequency sound, such as engine/road noises, and block them out. The signal is sent to its ANC processor to produce a reverse phase audio signal and is sent back to the speaker system. The inverted phase signal will cancel out the internal/external low-frequency sound, blocking out any unwanted noise.

 

When you add an aftermarket subwoofer into the mix the ANC system hears the subwoofer output as being part of the engine/road noise. The ANC system believes the low-frequencies being emitted by the subwoofer are part of the unwanted noise and this leads to the ANC system producing an out-of-phase low-frequency signal to block the sub's output.

 

To identify if your vehicle has an ANC system you can do one of two things.

 

1. Look up your vehicle's specifications online and verify if an ANC system is installed.
2. Drive your vehicle, play music, put your vehicle in park, and then either turn off the engine or open your door. If the subwoofer plays as it should you'll know you have an ANC system.

To fix the sound issue you'll need to disable the ANC system. You can accomplish this by doing one of three things.

 

1. Contact your dealership to see if they can disable the ANC system
2. Use an ANC Bypass Harness
3. Disable the ANC system yourself

 

There is a setting in the JBL One app called Bluetooth reconnection. You can change the behavior to enable it to automatically reconnect every time the speaker is turned on, if this is the behavior you want.

We believe the baseline performance of the QuantumSPHERE technology is cutting edge in terms of localization. The calibration feature improves upon this performance by calibrating the system to your individual anatomy.

If the preset DAB/FM station signal is not strong enough the alarm will go off in buzzer mode instead. Make sure the signal is strong enough, by checking that the station plays without static or distortion (FM).

If you have a mesh network (more commonly seen in Eero Mesh networks), it is possible that you may experience your satellite speakers or subwoofer intermittently disconnecting from the soundbar. This is similar to normal interference that occurs with products on a similar wireless frequency. The special thing about Eero mesh networks is that they do not allow you to move a device to the 5Ghz or 2.4Ghz band. The system will automatically decide which devices should be on which band and will move them accordingly (switching whenever needed). Some of our soundbars run on a 5Ghz frequency which is where the interference can occur. Since we cannot change the signal in which they operate and we cannot change the band they are connected to via their Eero mesh network, there are a few things you can do to try and stop this from occurring. 

  

1. Move the mesh nodes far away from the soundbar 
2. Use the 2.4Ghz band instead of the 5Ghz band (if your mesh system allows this) 
3. Ensure to enable/utilize the MU-MIMO setting (not applicable to all mesh systems). Please refer to your router's website to see if MU-MIMO is being utilized by default. 

  

What is MU-MIMO? 

MU-MIMO stands for Multi-User, Multi-Input, Multi-Output. This allows for the router to send a signal to multiple devices at one time vs. the previous version in which the router would be able to connect to multiple devices, but only send the signal to one device at a time. 

  

NOTE: You may notice that when the soundbar is turned on, there may be a dip in the immediate internet speed, but it will go back to normal within less than a minute.

This speaker has a USB-C charging protection safety feature. This safety feature will play an alert sound & cause the LED indicators to flash when the charging port has detected water, salt, or other chemical. When you encounter the alert you will need to remove the charging cable, wipe down any excessive moisture on or around the charging port, and leave the speaker in a area to completely dry off. Once it is completely dry, you'll be able to plug the USB-C cable back in and charge your speaker.

The internal cable is about 5 cm long, including the micro-USB plug. The flexible part is about 2.4 cm. This length has been chosen to permit the case to be closed without the cable being in the way, or be closed with a pair of in-ear headphones inside the box. In-ear types with big battery boxes or remote controls may not fit inside the closed case. On-ear or over-ear types will often have the charging socket placed in such a manner that you can arrange the cable to reach the socket.

This is because standard USB charging is possible from so many sources and chargers, and also from computers. There is a charging cable in the box, which permits charging from all USB chargers of at least 1A capacity.

In the ANC on mode, we take advantage of advanced signal processing to finely tune, and personalize the audio performance. In passive and in ANC off mode, that signal processing is not running, so you may hear a difference in audio performance

Using Wi-Fi allows you to listen to your music in a higher sound quality since Bluetooth protocol compresses the audio signal, where Wi-Fi data easily stream HD Audio content. Take calls without interrupting your current audio music, where Bluetooth will interrupt the stream, because it is a one-way protocol. Control your music from anywhere in the house, where Bluetooth have a limited range. Play the same music across multiple speakers and when using the newest connect features, such as Spotify Connect or Chromecast built-in, then you don't have to worry about battery life, since the devices playing is doing all the data transmission compared to Bluetooth, where it is data between source and device.

This speaker will go to standby mode after 10 minutes inactivity. It turn on when you start playing to it again.

Only if you have pressed the button on the remote or Boost TV itself.

No - it is not designed to work with a wireless microphone.

Yes, when casting music to your JBL Playlist, your speaker is connected to Google Cloud, which will turn your smart device into a remote control, rather than streaming music directly to the Playlist. You can easily do other things with your phone while using Chromecast, such as gaming, texting, make calls, watch Youtube etc. This will not interrupt the music that you are casting.

Yes, after 10 minutes of no audio activity, the soundbar will enter standby-mode automatically. Or you can do it yourself by short pressing the Power button.

No, the re-broadcast signal is in stereo. Stand alone speakers will play both Left and Right channels.

Yes, if no audio is present and no buttons are pressed, DUET will go into standby after approx. 10 minutes.

Yes, it will only go back to default volume if the power is switched off or if the device is reset. The standard volume is set to 50%.

The core settings: EQ, smart button, auto features will be recalled from the headphone when recharged. Ambient aware settings will default to off when the headphone is restarted after charging.

There is no plan for adding JBL Connect support for Playlist speaker. But you can group any speaker together that support Chromecast built-in for multi-room experience.

No, it will not change the TruNote autocalibration results. TruNote equalizes the acoustics of the headphones to the specific fit to your head As is the case with any supplemental equalization setting, it will change how the audio sounds to the user

No, you can certainly take off the front grill if you like the design of the speaker without the grill. However, do not touch the tweeters or woofers, as they can be damaged if you touch them. For ourdoor purposes, we do not recommend taking off the front grill.

The speaker is not intended to play under water, but it will continue to play even though it is submerged under water.

Yes. This product has battery power save features.

 All JBL Quantum headset models work only through 3.5mm audio jack (aux) connected to the Xbox controller. You cannot connect to any Xbox Series console via Bluetooth. 

Please note: JBL QuantumENGINE is only available on PC.
