Troubleshooting Your JBL Cinema SB350 Subwoofer
If you’re facing difficulties with your subwoofer, there are several steps you can take to diagnose and potentially fix the issue.

What should I do if my JBL Cinema SB350 subwoofer won’t turn on?
If your JBL Cinema SB350 subwoofer isn’t powering on, the first step is to check the power connection. Ensure that the power cord is securely plugged into both the subwoofer and a working electrical outlet. If possible, try plugging another device into the same outlet to confirm that it is providing power. Additionally, check the subwoofer’s power switch to see if it is turned on.
If the subwoofer still doesn’t power on after checking these connections, there may be an issue with the internal components or the power supply. In this case, it’s best to unplug the subwoofer for about 10 minutes and then plug it back in. If it still does not turn on, consider contacting JBL customer support or taking it to a certified repair service for further diagnosis.
How can I fix audio lag between the subwoofer and my TV or soundbar?
Audio lag can be a common issue when setting up your JBL Cinema SB350 subwoofer with a TV or soundbar. To resolve this, first check to ensure that the subwoofer is properly connected. If you’re using an HDMI or optical cable, make sure the connections are secure and that the proper input source is selected on your TV. Additionally, check if your TV has any sound delay settings that can be adjusted for synchronization.
If audio lag persists, you may want to try adjusting the delay settings on your sound system. Many soundbars and TVs have an audio delay feature that can help synchronize the sound from the subwoofer with the audio coming from the other speakers. Refer to your device manual for instructions on how to adjust these settings. If needed, you can also explore firmware updates for your devices, which may also help alleviate the issue.
Why is my subwoofer producing distorted sound?
Distorted sound from the JBL Cinema SB350 subwoofer may indicate an overload in the system, incorrect settings, or faulty connections. Make sure that the volume on both the subwoofer and the connected device isn’t set too high. Overdriving the subwoofer can lead to distortion. Check the audio source settings as well; settings such as equalizer presets can sometimes negatively impact sound quality, particularly if bass levels are too high.
If adjusting the volume and audio settings does not resolve the distortion, inspect all connection cables for wear or damage. A defective cable can introduce noise and distortion into the audio signal. If you’re using wireless connections, ensure that there are no interference issues from other devices. If the problem continues despite these adjustments, it may be necessary to seek assistance from JBL’s customer service or consider having the subwoofer professionally evaluated.
How can I connect my JBL Cinema SB350 to my TV?
Connecting your JBL Cinema SB350 to your TV can be done through various methods, with an optical cable being the most common and straightforward. Start by locating the optical audio output on your TV and connect it to the optical input on the subwoofer. Make sure to select the correct audio output on your TV settings to send sound through the optical source.
Alternatively, you can connect the subwoofer using HDMI ARC (Audio Return Channel) if your TV supports it. Simply connect an HDMI cable from the TV’s ARC-enabled port to the HDMI port on the subwoofer. Once connected, ensure that your TV’s audio output settings are configured to use HDMI ARC. This method not only transmits sound effectively but also allows for easier control using your TV remote.
What can I do if the subwoofer is not syncing with the soundbar?
If your JBL Cinema SB350 subwoofer is not syncing properly with your soundbar, the first step is to verify the connection between both devices. Ensure that the soundbar is correctly configured to send audio to the subwoofer, which may involve checking settings in the soundbar menu. Look for options like ‘wireless sub’ or ‘subwoofer pairing’ to help establish a solid connection.
If the problems persist, try resetting both the soundbar and the subwoofer. Often, a factory reset can help resolve minor glitches that disrupt syncing. Once reset, reevaluate the pairing process, ensuring to follow the steps provided in the user manual for both the soundbar and subwoofer. If these steps do not work, consult the manufacturer’s support resources for advanced troubleshooting.
How can I improve the bass performance of my JBL Cinema SB350?
Improving the bass performance of your JBL Cinema SB350 can often be achieved by adjusting the placement of the subwoofer within the room. Ideally, placing the subwoofer in a corner of the room can enhance bass response due to boundary reinforcement. Experiment with different locations to find the spot that delivers the best sound quality, taking care to ensure that it isn’t obstructed by furniture.
Additionally, consider adjusting the settings on your receiver or soundbar. Most devices allow you to modify bass levels through equalization settings. Increasing the low-frequency output and ensuring the crossover frequency is set appropriately can significantly enhance the overall bass response. Lastly, keep in mind that the acoustics of the room play a significant role; adding soft furnishings like rugs or curtains can help improve sound quality by minimizing reflections and echoes.
What is the best way to troubleshoot connectivity issues with the subwoofer?
When troubleshooting connectivity issues with your JBL Cinema SB350 subwoofer, start by checking all physical connections. Ensure that the audio cables are securely connected to both the subwoofer and the audio source, whether it’s a TV, soundbar, or AV receiver. If you’re using a wireless setup, verify that the subwoofer is powered on and in pairing mode, which usually involves pressing a button on the subwoofer itself.
If connections are intact and the subwoofer still lacks connectivity, try resetting the wireless connection by unplugging the subwoofer for a few minutes. After reconnecting, reattempt the pairing process. Additionally, consult the user manual for specific instructions related to network settings or firmware updates, as keeping your firmware updated can often resolve connectivity problems. If the issue persists, reaching out to JBL customer support may provide further insights.
