Is this the article? https://www.highdefdigest.com/news/...und/upmixed-dolby-surround-v-dtsneuralx/32382The "+Dolby" is your receiver upmixing the source to include any additional speakers you have. This brief HighDef Digest article has the listener doing a quick review; I find it is a good starting point to understanding what Dolby Surround and DTS Neural: X.
PCM Multi In is the direct audio feed from the source. The audio display is in two parts: {Direct Feed from Source} + {AVR upmixing}
You say you have 5.1 speakers. I would think that you couldn't upmix a 5.1 feed to 5.1. How do you have your speaker configuration set up?
Oh ok! Does the "+" always mean upmix? If that's the case should I avoid upmixing when possible?
My configuration is 2 fronts, a center, a left and right surround. and a subwoofer. All speakers are set to small with an 80hz crossover. Subwoofer is set to Lfe. And lpf for lfe is set to 120hz.
I don't really notice a difference between setting my avr to auto and it selecting multi ch in and me physically pressing game and choosing multi in + Dolby surround. The only difference is setting it to auto makes me have to turn the volume down from 44 to 38 cause it's louder for some reason.
Should I just do multi ch in and forget about the +Dolby surround? Thanks for the help everyone btw :)
