I have the following
Wave Music System III
Hello SevenStones,
Thank you very much for messaging the community, I am very sorry to hear that you are experiencing too much Bass from your Wave Music System III. I would love to do what I can to get this resolved for you.
I would recommend that you contact your regions support team who will be able to issue you with an update disc. Please follow this link, select your region and scroll down to "Contact Us". There you will find the appropriate contact information and an agent will happily assist you with this.
Following the software update please follow these instructions on how to adjust the system tone controls.
Note: Selecting "NORMAL" selects the default / normal system bass response. Selecting "REDUCED" applies a bass cut to all source audio played through the system. This can be helpful, for example, on talk radio stations where voices sound boomy or muffled
I hope this helps! Please let us know how you get on.
