Hi all,
I know the topic of bitstream versus PCM has been discussed before. After reading the previous threads, however, I still have questions.
When I play a blu-ray DVD in my Panasonic DMP-BD10AK I can only access some of the sound options. For example, last night I watched "Tears of the Sun." If I chose "English 5.1" from the DVD's audio options and "PLII Movie" on the AV 350 the sound was fine. However, if I selected "English PCM 5.1 Uncompressed" from the DVD's audio options and "PLII Movie" on the AVR 350, there was no sound going to the subwoofer.
My blu-ray player is connected both by a digital coaxial cable (Stereovox XV2) and multi-channel connections (Wireworld Rainbow 5.1). My blu-ray player handles Dolby Digital , Dolby TrueHD (downconverted to 24/96), Dolby Digital Plus, DTS-HD (core, but not DTS-HD Master Audio) and DVD-A.
From previous threads, I know one possibility is that I have to change my Left and Right speakers from "large" to "small." I hate to do this because they are full range speakers (Acoustic Zen Adagios). I cross the sub (JL Audio Fathom F113) over at 40 hz, because I really only want it for subterranean bass.
Also from previous threads, it sounds like I can run the sub from the line out (DVD out) connection. I haven't tried this yet. But if that allows me to leave the front L/R speaker on "Large" I'm willing to give it a try. Would I need to use both the left and right outs and sum them with a Y connector?
I'd also like to know if I should change the blu-ray's set-up options from PCM to bitstream. Here is how the blu-ray player is set-up now:
Digital Audio Output
PCM downconversion = Off
Dolby digital = Bitstream
Dolby digital Plus/Dolby TrueHD = PCM
DTS = Bistream
DTS-HD = PCM
Are these settings as they should be? As I understand it, setting the audio output to "Bitstream" allows the AVR 350 to do the processing, while setting it to "PCM" lets the blu-ray handle the processing. I prefer doing the processing in the AVR 350, because I have a choice of cross-overs.
One last question, which audio formats require the multi-channel connection and which rely on the digital coaxial connection? Or stated somewhat differently, when I'm listening how do I know which connection I'm hearing?
Sorry if I seem naive. There are so many audio formats and connections out there, I suspect others would like to know this too.
Thanks in advance,
Dr. Gass
