  2. Tap the soundbar image in the bottom-right corner of the screen
  3. Under the Accessory Settings section, the toggle switch of the bass module should be positioned to the right to enable this accessory
  • If the switch postion is on the left, tap the switch once to turn on the bass module

Check for sources of wireless interference that may be within a few feet of the soundbar or bass module. Devices that can affect the wireless performance of the system include, but are not limited to, a cordless phone, Wi-Fi® router, wireless printer, or microwave.

To identify a possible source of interference, try temporarily unplugging the device and restarting the Bose system to determine if performance has improved. 

Relocate the Bose system or device causing interference. This may require at least six feet of distance between the two devices. For devices that cannot be relocated, change the Wi-Fi channel or wireless frequency used by that device.

Reset the soundbar and bass module by unplugging their power cords from the power outlets, waiting 30 seconds, then firmly plugging the power cords back into working outlets

If wireless interference may be present and cannot be alleviated, consider using a wired connection to the bass module. In some setups, it may not be possible to relocate the bass module, Wi-Fi devices, or other sources of interference

To resolve such an issue, connect an audio cable with 3.5 mm male connectors at both ends between the BASS output of the soundbar and the BASS IN jack on the bass module.
