It appears that the Cinemate 520 receiver cannot process the 4K signal with HDCP 2.2 adaptability. Are there any recommendations of using a different receiver to achieve it?
Thank you for the post and welcome to the Bose Community!
The Bose console you have is specifically designed for the speakers and the bass module you have. There would not be another receiver compatible with that setup.
The HDCP version on this console is 1.4 as 2.2 was not available when this system was developed.
Let us know if you have any other questions.

Get a HDFury Intergal 2 just like I did. It will solve all the problem. Just connect the 4k source to Intergal 2 and let it pass the HDCP 2.2 video signal to TV and audio signal to Bose.
