Subwoofer was disconnected to the soundbar,i did the trouble shooting but still unable to connect.is there any other ways to fix the problem?

These components are meant to be compatible with each other, providing a seamless audio and video experience. Here's how you can connect them:

1. Connections to the Media Center:a. Soundbar Connection: Connect the Bose Lifestyle 135 soundbar to the MC1 media center using an audio cable. Depending on the available ports on both the soundbar and media center, you might use an optical audio cable, coaxial audio cable, or another appropriate audio cable type.
   b. Subwoofer Connection: The Bose Lifestyle 135 subwoofer is a wireless subwoofer, which means it connects wirelessly to the media center. During the initial setup process, the subwoofer should automatically pair with the media center. Follow the instructions in the user manual to ensure proper pairing.
2. Speaker Setup:
   The Bose Lifestyle system, including the MC1 media center, typically uses Bose's ADAPTiQ audio calibration technology. This technology helps optimize the sound based on your room's acoustics and speaker placement. Run the ADAPTiQ calibration process as outlined in the user manual to ensure the best sound quality from your system.
3. Remote Control:
   Ensure that the remote control provided with the Bose MC1 media center is properly programmed to control both the media center and the soundbar. If needed, follow the instructions in the user manual to set up the remote control for seamless operation of all components.
4. Audio and Video Sources:
   Connect your audio and video sources (such as Blu-ray players, cable/satellite boxes, game consoles) to the appropriate inputs on the Bose MC1 media center. This allows you to route both audio and video signals through the media center and enjoy them with the soundbar and subwoofer.
5. Power On and Configuration:
   Power on the Bose MC1 media center and ensure that the soundbar and subwoofer are also powered on. Navigate through the media center's on-screen menus to configure the audio settings, input sources, and any other preferences.
6. Testing and Adjustment:
   Play different types of audio content to test the sound quality from the soundbar and subwoofer. Adjust the volume, bass, and other audio settings to your preference using the remote control and on-screen menus.

Remember to consult the user manuals for both the Bose MC1 media center and the Bose Lifestyle 135 soundbar for detailed setup instructions and troubleshooting tips. If you encounter any difficulties during the setup process, Bose customer support can also provide assistance.

it is designed to only connect to the soundbar

It occurs to me that if the sub is no longer sending signals back to the unit then it won't find it. I am certain that it should be easy to have the sub repaired so that it does send out the signals.

Most likely, the "remote" wire to the subwoofer amplifier has come off or is not making good connection.

The coax out is a digital sound output. You can not use that on your soundbar. The sub out is for hooking the tv to a subwoofer (bass only). You gonna have to use the Headphones output, buy a good 3.5mm to rca cable preferably one with a built-in noise filter so it can attenuate the "hum". Also try lower the volume on the TV so you can have less distortion. That's all!

hello anonymus if your system is working and the soundbar does not
make sure you have the right connector to inject signal to soundbar some of them like you have has a tiny hole to reset it and dont forget to use the remote control i hope it works

Not sure the issue. HDMI from cable box to TV. Same with Vizio.
The soundbar usually connects to the optical out from the TV to the in on the soundbar. Subwoofer has to be paired to the soundbar. Instructions should explain or maybe find online by manufacturer

Check the receiver in the speaker and the amplifier. they both have to work to get sound.

If you have your soundbar connected via HDMI, look for an option to disable the link between your TV and your soundbar (when this option is on on the devices connected toghether, when you turn off/on any of them automatically does to the same with all devices).

No adapter. Your sound bar has to have wireless built in.
