Powernode 2025 Dolby Digital
I recently purchased and started using a Powernode 2025. I have two Klipsch bookshelves and an RSL Speedwoofer 10e connected to it, and it's connected to my TV via eARC. The sound is fantastic. That said, I purchased the Powernode partially for its upgradeability - I plan to add a Klipsch center channel and two Bluesound speakers for rears. My question is...since the Powernode supports only DD, what happens when I watch something encoded in DTS? Will the Powernode try to approximate surround sound in some way, or will it simply default to stereo? Also, when watching something in Dolby Atmos, Dolby TrueHD, etc., will the Powernode simply output "standard" DD 5.1?

Since the Powernode 2025 only decodes DD 5.1 AC3 for surround, it depends on devices connected to it for converting the sound to AC3 DD.
Most tv's detect the capability of the Powernode through eARC and provide (convert) source audio to a a compatible AC3 sound, using for example the Dolby Multistream Decoder MS12 chip.
Chances are passthrough DTS bitstream will result in no sound. In those cases you need to rely on videoplayers like Kodi to convert the DTS stream in the source to a compatible DD stream on-the-fly.
This is how I use my Powernode 2025.
