Bluetooth­-enabled soundbar with a powerful, 200-watt wireless subwoofer.

Bluetooth¬-enabled soundbar with a powerful, 200-watt wireless subwoofer. High-definition TV is great – but what good is it if its sound doesn’t match the quality of its video? Fortunately, the JBL® Cinema SB400 system offers cinema-quality audio in a small space and high style. Its two-channel soundbar features four 2-1/4-inch (57-millimeter) woofers, two 1-inch (25-millimeter) tweeters, an amplifier that delivers up to 120 watts, integrated Bluetooth® technology for streaming music from digital devices, three HDMI® inputs and HARMAN Display Surround technology, which creates a 3D listening environment from only two channels. The system also includes a 200-watt, 8-inch (200-millimeter) wireless subwoofer with bass-boost control. The SB400 is everything that you can ask for in a sound system.

The Cinema SB400 incorporates amplifiers, controls andleft and right woofers and tweeters into a single soundbar. Its built-inamplification simplifies system connections and operation, and offers up to 120watts of power.
Nothing draws you into the action like huge bass. TheCinema SG400’s 8-inch (200-millimeter), low-frequencytransducer and built-in 200-watt amplifier deliver all of your entertainment’simpact, emotion and excitement. And because the system is wireless, it puts nounsightly cables between soundbar and subwoofer.
Movies and TV shows aren’t the only things that soundbetter with a JBL soundbar. The Cinema SB400 wirelessly streams music fromsmartphones and tablets, delivering room-filling, full-range sound reproductionwith exceptional bass.
With three HDMI inputs, the Cinema SB400 providesconvenient connection for multiple HDMI source components. It also includes oneHDMI output with Audio Return Channel (ARC), which sends the TVsound back to the soundbar. This setup simplifies switching and makes thesystem easier to use.
Drawing from HARMAN expertise in movie theater audio, theCinema SB400 lets you add cinema sound without adding multiple speakers.Employing proprietary HARMAN Display Surround technology, it creates a virtualsurround-sound experience while preserving the original audio mix in its timbreand special balance.
The Cinema SB400 decodes film soundtracks in their nativeformat, which eliminates conversion stages that reduce sound quality. Thisarrangement helps the soundbar provide a superb surround-sound experience formultiple listeners.

FAQs & How-Tos

6 results
  • My JBL SB400 should turn on automatically when receiving an audio signal at either input, according to the owner's manual. However, this does not happen.
    We are sorry about this problem. EuP regulations require that electronics go into full off after some time. Unfortunately, this means that the soundbar cannot be woken up again after half an hour. It is necessary to use the ON/OFF switch.
  • My remote control is not working. I have a credit card-sized remote with disc type battery. Do I need to replace the remote control?
    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.
  • Pairing the soundbar and the wireless subwoofer takes a long time, and sometimes the connection will not open.
    First time you perform the pairing, it can take several minutes to establish connection. If more than five minutes go by with no result, please switch both units OFF and ON again.
  • What does HARMAN volume do?
    With HARMAN Volume you can set your desired volume between low, medium and high. You can listen to your audio without sudden distracting changes such as blasts from ads, and volume variations as you switch between channels on your TV. Other benefits include full sound effects even at low volumes, this means if you are watching movies (DVD, BlueRay disc) and HARMAN volume is set to low volume, then the signal is more compressed, than what the other volume levels is. This will allow you to hear natural, consistent sound at low volume level, and not only hearing voice conversation from movies, giving you the same movie experience just with lower volume. What is best for you is a matter of personal preference, so we recommend playing around with the three different levels.
  • When I am trying to program my Cinema SB100, 200 or 400 to learn the volume up, down and the mute codes from my TV remote controller, I can only get mute, or perhaps mute and a volume code, to work correctly. What is wrong?
    This problem is usually caused by pressing down too hard on the soundbar's VOL + or VOL - Buttons. Only press just enough for one click to be felt. If a second click is felt in the button, you are pressing too hard, and you are actually activating the MUTE function for learning, not VOL up or down. You may have to repeatedly let go of the VOL button on the soundbar, followed by pressing it again and then pressing the VOL button on the TV remote before the surround light on the soundbar lights up white and goes back to amber flashing, as a sign that this function has been learned. This is no problem, though. Just keep trying until the three commands have been learned. The soundbar only exits learning mode when you press and hold the surround button as the final step.
  • Why is my soundbar having interference issues with my mesh network?

    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.
