Just use the TV inputs for your video sources and you will have full resolution. Run the Audio through the SSP-800 with HDMI eARC from TV and it will send the sound no matter what video source to the Audio Processor. I had this Classe SSP-880 and ran it this way with no issues. If you have issues with HDMI eARC (Audio Return Channel) you can also run Optical out of TV into the SSP-800.
Getting 4K with Classe SSP-800
We have a nice but older home theater setup with a classe ssp-800, classe multi channel amps and B&W 800 series speakers. We now have a new Sony 4K TV and a 4K apple TV and we want to get the 4k video and the best quality 5.1 audio going through the classe ssp-800 preamp that we have - is there anything out there that would help us with this? Audio extractors? Etc. We would prefer not to replace the preamp if possible.
Thanks
