FAQs & How-Tos

  • Is there a visual display on the JBL Bar Studio, Bar 2.1, Bar 3.1, Bar 5.1, and Bar 9.1?

    Yes. All but the Bar Studio model have an LED display on the soundbar's front panel. The display tells which source input, volume level, and sound feature you are on. You are able to dim the display, using the remote, during low light usage.

  • I can't listen to music on my JBL Soundbar while the TV is off. How can I change this?

    The TV turns on with the soundbar. This is caused by CEC commands from your TV via the HDMI port. Please disable these functions on your TV, to use the soundbar while TV is off.

  • Does the soundbar upscale my video to 4K resolution?

    The soundbar passes through content from a 4K video source but does not upscale video to 4K.

  • 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.

  • Will my soundbar enter standby-mode automatically?

    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.

  • How do I turn off my internal TV speakers?

    Every TV is different, but most current TVs will let you turn off your internal TV speakers in the Settings menu under the Audio section.

  • How do I pair the subwoofer to my JBL BAR soundbar if pairing does not happen automatically?

    Normal pairing is automatic, and happens when you first switch both devices on. If pairing does not take place automatically, or you have to force new pairing, here is what to do: Turn on the soundbar and the subwoofer. If the connection is lost, the LED indicator on the subwoofer blinks slowly. Second, press the CONNECT button on the subwoofer to enter pairing mode. The LED indicator on the subwoofer blinks quickly. Third, press and hold the DIM DISPLAY button on the remote control for 5 seconds, followed by short press on BASS+, and BASS- button in sequence. Panel display will show “PAIRING”. If pairing succeeds, the LED indicator on the subwoofer lights up, and the soundbar display will show "DONE”. If pairing fails, the indicator on the subwoofer blinks slowly. Lastly, if the pairing fails, repeat the steps above. If you have continued trouble performing the pairing, please try to switch off all wireless devices in the home, then try again. This means routers, TV sets with wireless functions, telephones, computers etc. Since overcrowding on the 2.4 GHz frequency now often causes problems, eliminating all this activity makes space for the Bar to establish its connection, and you should be able to pair without problems. Afterwards, you can switch your devices on again. Often, all will now work fine, and if not, you will know which devices are doing the interference.
