JBL Bar 3.1

The powerful JBL Bar 3.1 system includes a wall-mount to fit neatly into your TV setup.

Hear characters talk again

Sound bars in general are an easy, space-friendly way to improve TV sound. But the JBL Bar 3.1 solves one very specific problem. Our customers often tell us that TV dialogue is too hard to hear and understand. JBL includes a center channel that's dedicated to making speech loud and clear — even in movies and shows with heavy action.  

Powerful sound effects, too

But it's not all about speech. This system gives you a fully-formed home theater experience with deep bass and simulated surround sound. The bar features nine total drivers, positioned to deliver sound to a wide viewing area. And the included sub adds hard-hitting emphasis to big effects.

I heard this system briefly in our training room — a large space with a lot of open air. The Bar 3.1 was able to cut through the dead spots with full-bodied, exciting sound. Frankly, the sound added some depth and character to the mindless movie clip I was watching! I paid more attention to the on-screen action than I otherwise would have.

Space-friendly design with versatile connections

The bar is slim enough to fit under most TVs on a stand, but JBL included a bracket for wall-mounting. You'll find convenient home theater connections to go with this system's home theater performance. There are three 4K/HDR-ready HDMI inputs and one output for connecting the latest gear. Or you can simply connect your TV using the single included optical digital audio cable.

Quickly switch over to Bluetooth for music

Sound bars have now become one of the more popular ways to listen to music, too. So JBL made it easy to pair up and play. Their SoundShift feature swiftly — and automatically — switches over from your TV input to Bluetooth when it's time for some tunes.

    The JBL Bar 3.1 replaces these items:

    Product Research


    Active Soundbar:  The JBL BAR 3.1's active soundbar speaker features a dedicated left, right, and center channel for excellent stereo imaging and enhanced voice clarity. Each channel of the soundbar speaker houses one 1.25" tweeter and two 2.25" racetrack drivers. The three 1.25" tweeters and six 2.25 racetracks drivers are  powered by a 150 watt (Peak) amplifier for dynamic sound performance.

    • JBL Surround Technology: The soundbar incorporates JBL's Surround Sound Technology with six sound modes to choose from - including Standard, Movie, Music, Voice, Sports, and Off (Stereo).
    • Night Mode: There is a Night mode that reduces major volume differences between soft and loud passages, so a more uniform volume level can be maintained.
    • Audio Sync: The Audio Sync feature makes sure that the sound from the BAR 3.1 is in sync with the video on your TV; the Audio Sync can be adjusted from 0-250ms.

    Wireless Powered Sub: The JBL BAR 3.1's wireless powered sub features a down-firing 10" woofer in a bass reflex enclosure with a rear-firing port. A built-in 300 watt (Peak) amplifier is used to drive the 10" woofer and deliver deep, impactful bass. Because the powered sub is wireless, it puts no unsightly cables between the soundbar and subwoofer (still requires a AC power cord connection). You can adjust the bass level (0-20) of the powered sub from the included IR remote.

    HDMI 2.0a Connectivity: The JBL BAR 3.1 is equipped with three HDMI inputs and one HDMI ARC output. All of its HDMI inputs and output support the latest HDMI 2.0a specification with ultra high-definition 4K video pass-through, HDCP 2.2 compatibility, HDR (High Dynamic Range), ARC, & Dolby Digital (up to 5.1ch).

    • 4K Pass-Through: The BAR 3.1 lets you maintain 4K quality from source to screen by allowing 4K video to "pass through" and be displayed on a 4K TV or projector, without compromising image quality. Giving you the pure 4K experience makes this soundbar the perfect partner for 4K-capable TVs and Ultra-HD Blu-ray players. 480i, 480p, 720p, 1080i, and 1080p video signal are also supported.
    • HDCP 2.2: HDCP 2.2 is supported by all of the soundbar's HDMI jacks. HDCP 2.2 is short for "High bandwidth Digital Content Protection" and is used for 4K video copyright protection for compatibility with Ultra HD Blu-ray players and 4K Satellite/Cable providers.
    • HDR (High Dynamic Range Video): HDR (High Dynamic Range) reproduces a greater dynamic range of luminosity or brightness levels, bringing greater contrast & wider color spectrum to the screen. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth. Previously hidden areas of dark shadow and sunlight are now full of clarity and detail. The BAR 3.1 supports HDR10, the most popular HDR format.
    • ARC (Audio Return Channel): This feature of the soundbar speaker system's HDMI output allows audio to be sent from your compatible HDTV to the BAR 3.1 through the same HDMI cable already being used to send audio and video to your HDTV. This eliminates the need for extra cables connected to your television.
    Note: The ARC-enabled HDMI input of many televisions only sends an audio signal in 5.1ch when receiving Dolby Digital from the TV's built-in tuner, network connection, or connected USB device; and will output only 2ch stereo from sources connected to the TV via HDMI, or RCA (like your Blue-ray/DVD player or satellite/cable box).

    Optical Digital & Analog 3.5mm Inputs: In addition to HDMI connectivity, the JBL BAR 3.1 is outfitted with one optical (toslink) digital input and one analog stereo minijack (3.5mm) input. The optical digital input will support 2ch PCM and Dolby Digital (up to 5.1ch).

    Note: The digital optical output terminals of most newer flat-panel TVs only send an audio signal in 5.1ch when receiving Dolby Digital surround sound from the TV's built-in tuner, network connection, or connected USB device; and will output only 2ch stereo from sources connected to the TV via HDMI, or RCA (like your Blue-ray/DVD player or satellite/cable box).

    USB-A 2.0 Port: The JBL BAR 3.1 features a USB (type-A) 2.0 port for connection of a USB MSC (mass storage class) device, such as a USB thumbdrive or portable digital audio player. You'll be able to playback MP3 and WAV music files stored on a USB MSC device (formatted in FAT 16/FAT32) through the JBL soundbar system. The system can recognize up to 2,000 MP3 files. You'll also get basic playback control (such as Play/Pause,  Previous/Next Track, and Random/Repeat) from the included IR remote. Advanced music browsing and song/artist/album info display are not supported. The USB port can also be used to charge (5V/1A) your connected device.

    • Supported MP3 Files: 16kHz-48kHz sampling rate with 80kbps-320kbps bitrate.
    • Supported WAV Files: 16kHz-48kHz sampling rate with up to a 3000kbps bitrate.
    Note: The USB port does not support Apple iOS or Android OS device playback.

    Bluetooth Audio Streaming: The JBL BAR 3.1 is equipped with built-in Bluetooth 4.2 with support for wireless audio streaming (A2DP 1.3) and playback control (AVRCP 1.6). You'll be able to wirelessly stream stored music, music apps, and other audio content from your Bluetooth-enabled device (such as your smartphone, tablet, laptop, or computer) to the soundbar speaker system. You'll also be able to control basic playback functions (such as Play/Pause & Previous/Next Track) from the included IR remote. You will still use your Bluetooth source device for advanced music browsing and to view song/artist/album info. You can pair multiple Bluetooth devices with the BAR 3.1, but only one device can be used for playback at a time. The system has a wireless Bluetooth range of approximately 32'.

    Note: The JBL BAR 3.1 does not support Bluetooth hands-free communication for making and answering phone calls.

    JBL SoundShift Technology: The JBL BAR 3.1 is further enhanced with JBL SoundShift technology, which allows you to instantly switch between sound from your TV and sound from your Bluetooth source device.

    Remote Control: The JBL BAR 3.1 comes with an IR remote for wireless control of the soundbar system, as well as basic playback control of USB & Bluetooth connected devices. The system also supports "System Standby" and "One Touch Play" HDMI CEC commands. In addition, the BAR 3.1 can respond to "Volume Up/Down" and "Mute" commands from most Samsung, Sony, LG, and Vizio TV remote controls automatically (no programming required). If your TV's remote does not control the soundbar automatically, you can program the BAR 3.1 to respond your TV remote's "Volume Up/Down" and "Mute" commands.

    Front-Panel Display: The front-panel display indicates source selection, surround modes, and other audio settings. The front-panel display can be dimmed and will disappear after five seconds. The front-panel display does not offer song/artist/album information.

    Mounting Options: You can place the JBL BAR 3.1's soundbar speaker on a shelf or tabletop, or wall-mount it with the included brackets. Because the powered subwoofer is wireless, you can position it any where in the room (within 25').

    Power Requirements: Both, the active soundbar and wireless powered sub, will need to be plugged into an AC wall outlet, surge protector, or power conditioner.

    Auto On + Standby: The JBL BAR 3.1 system will automatically power on whenever it senses an audio signal from its HDMI & Optical source inputs. The JBL BAR 3.1 will automatically switch to standby mode after approximately 10 minutes of button inactivity and no audio playback from a connected source.

    Sorry , I cannot answer the question as posed, I bought the soundbar for my daughter. Being a 7.1 guy myself, I heartily recommend a 5.1 setup and/or Atmos. You're going to need a device (receiver...) to decode the signals and propagate Bluetooth. I don't know if the JBL has these additional capabilities. Better call Crutchfield. I'm an old, old-school guy: Marantz 2275/JBL 100s in my office; Pioneer VSX-09TX/Paradigms in the bedroom, Marantz SR 5010 in the den; McIntosh MX 121/MC8207/Focals in my music room/Denon/Cerwin-Vega in the garage, all hard-wired (two setups partially wired with Crutchfield wire....). Regards, Al
    [ AL  Feb 19, 2020 ]
    I do not believe you can add wireless rear speakers to this set-up. I would recommend the JBL 5.1 setup that comes with rechargeable rear speakers
    [ Phillip Morris  Feb 19, 2020 ]
    [ JOHN O  Feb 19, 2020 ]
    I haven't tried to add wireless speakers but have connected my iPod to the soundbar. Sorry.
    [ Michael  Feb 07, 2020 ]
    I dont believe it's possible. But, I think the next model up has surround speakers. This is my second jbl soundbar and highly recommend. Best bang for the buck
    [ Donald  Feb 07, 2020 ]
    Do you hook your Firestick, PlayStation, and cable box to this with hdmi inputs and then one hdmi out to tv so all devices play through sound bar? Thanks
    [ CHRISTOPHER  Jan 01, 2020 ]
    1 answer
    I just connect a DVD player and cable box to the TV. I have a smart tv so don't need Roku or Firestick. Connect everything to the TV. Use the HDMI ARC to connect the JBL. When you do that the sound for all devices comes through the JBL. Hope that helps.
    [ Michael  Jan 01, 2020 ]
    Are the speakers facing up towards the top or out towards the front? I want to mount this directly below a tv with only 1/2â?? space but donâ??t want the sound to be adversely affected by doing so.

    Facing outwards
    [ Ryan  Jan 11, 2019 ]
    sound bar out towards the front. the sub will shoot sound into the floor. literally will shake the house if you let it. ours sits under/front of tv with great sound. really nice system.
    [ John  Jan 10, 2019 ]
    You will be fine to mount the bar under the tv. The sound comes out of the front and the sides. Great system, I hope you have good neighbors. IT ROCKS!
    [ JAMES  Jan 10, 2019 ]
    Speakers are front firing.
    [ Donald  Jan 10, 2019 ]
    They're forward firing, as far as I can tell.
    [ Ken  Jan 10, 2019 ]
    I believe there are nine speakers that project sound horizontally if the sound bar is oriented as designed. The metal speaker shroud wraps over the top where the control buttons are located. Access to the controls would be troubling if the bar is placed under neath your T.V. or shelf. However, the buttons on the bar are only needed to establish an initial connection to the subwoofer as the remote control contains all remaining functions.
    [ Ian  Jan 10, 2019 ]
    Towards the front. Speakers are facing front.
    [ Ivan D Hernande  Jan 10, 2019 ]
    I have my bar directly below a wall mounted TV. The sound bar is attached to the tv wall mount. It sits just a couple inches below the TV. No sound loss. It sounds great. I am VERY happy with this sound bar.

    If you press the half moon button on the bottom left of the remote, the display will show "Night On." If you press it again, the display will show "Night Off." I just did it to mine and it worked. I guess they must think it is intuitive. The manual does not mention it so I am guessing that is reason for the question. If that does not work, you can try a factory reset located on page 8 item 4. Good luck.
