Sorry Evan, I am not familiar with 4K Ultra HD pass-through, but it does work good and has a lot of capabilities. So maybe you should call customer service at Bose, they are pretty good at answering your questions.
Hello, Damilola. Bose recommends that our systems be purchased in the country where it will be used. The Lifestyle T20 system does come with a dual voltage, auto-sensing power supply feature for both the media console and the Acoustimass Module. However, systems purchased in the United States come with the 120 volt plugs. If you do purchase the system for use in another country, then you will need to obtain the appropriate plugs that are required by the country you're going to use the system in. To reach our technical support department, for parts and additional questions, please call 1-800-367-4008.
I do have the system, but I wouldn't know about that. That would be a question you would want to ask Bose directly through their website. I doubt it is compatable though. I do have all my music on my ps3 that I added from my iPod though.
