I am interested in these newer Denon receivers - I do not yet have one, but am hoping owners in this thread can help explain what capabilities I can expect from the surround modes.
Specifically, I am trying to understand the table on pages 78 and 79 of the 1909 manual.
I plan on using a PS3 for Blu-ray movies with the PS3 doing the decoding and outputting the audio as Linear PCM. Looking at the possible settings for the Standard surround mode, the table shows both "MULT CH IN" and "MULT CH IN 7.1" as being the initial status. From the table's legend explaining the symbols, I am guessing that what it means is that if the AFDM flag is set to ON, then it is set at "MULT CH IN 7.1", otherwise, if the flag is OFF, it defaults to "MULT CH IN" and is also able to be switched to using PLIIx Cinema or PLIIx Music.
What I am trying to figure out with these receivers is what if you want them to apply PLIIx Cinema when they are receiving a 5.1 signal and not apply PLIIx Cinema and instead output all 7.1 channels discretely when it receives a 7.1 signal.
It looks like if the AFDM flag is set to ON, it seems like 7.1 signals would be output correctly, but 5.1 signals would not be able to have PLIIx.
So if the AFDM flag is set to OFF, and "MULT IN + PLIIX Cinema" was selected, then would that be the way to have it apply PLIIx for 5.1 signals yet just output 7.1 signals discretely if it receives 7.1? Or is there not a way to make that automatically saved to work in that manner and that needs to be switched manually by the user depending upon whether a 5.1 or a 7.1 source is being played?
