The AB40 Soundbase offers an immersive cinematic sound experience all in one convenient package. Sometimes not every TV/source plays nice so we wanted to offer some suggestions for changing your sound settings so you can be up and running in no time.
If you are experiencing difficulty using the Optical input you may need to change the audio output settings on your source device. The AB40 does not support Dolby Digital Audio. These instructions will help you disable Dolby Digital on common devices. The AB40 supports PCM audio but some devices refer to this format differently. For instructions on a specific device please consult the device’s user manual.
Note: The audio output format may need to be changed on the TV as well as the source device.
