How To

The top panel LEDs are flashing because the OTA firmware update is in progress, the product should work after the upgrade is completed. It may have been caused by a previous interruption to an update.

It should be possible to resolve the issue by doing the following:

• Plug in the power cable and wait for at least 5 minutes for the Partybox Ultimate to complete the update.
• If the Partybox Ultimate stops flashing, but cannot power on, then perform a factory reset by pressing the two buttons below for more than 10 seconds: Moment (heart symbol) and Play (or through the JBL One app). After this has been done, press the Power button. 

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.

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

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.
