Will a Proceed AMP handle LPCM input?


Does anyone know if the Proceed AVP will process linear pcm input? Namely, if I have a PS/3 decode the HD/Master Audio tracks, send them down the HDMI cable to a splitter/ssp which sends the audio output to coax/toslink to the AVP, can the AVP process the signal?

If the AVP can do, I'm sure the AVP2 can as well.

Thank you,

I looked in the owners manual for both the AVP/AVP2 and couldn't find a definitive thing either. Can you give me a lead on one of these little black box adapters? I am not familiar with them. Thank you.
I googled and found a little black box that converts LPCM into 2-channel analog. I want to keep the LPCM information in multi-channel. I guess I need to read up more on what LPCM really is.
I think I have found my answer out on the web:

Optical or Digital coax can only carry two channels of LPCM. HD Audio like LPCM will not pass over s/pdif (your optical connector). So if you want the benefits of that you will have to use HDMI to your receiver.

In other words, there is no way to get the HD audio format into an AVP.
Thank you HTH & Mezmo - you have answered my questions. I was hoping to indeed get the DTS-MA decoded in the PS/3 somehow into the AVP or an AVP2. Seeing as how I currently decode in the PS3 and send LPCM over HDMI into my Rotel RSP-1069 I was wondering if I could do something similar to the Proceed. But the DAC in the 1069 must know how to deal with multi-channel sounds in LPCM where as the DAC in the AVP/AVP would not (due to it's age).

I have this idea of using the 1069 for HDMI switching and send the audio out it's digital out port into the AVP/AVP2 to hand the sound reproduction. 2-Channel audio is of high importance to me.
Thanks TLS49 - I am aware of the proceed manual site. :-)

DB - I gotcha now. I think the labeling of the connections on the PDSD are what led me to wonder. Plus typical balanced cords you go male to female but it looks like you need male/male to connect the PAV to the PDSD.

That is crazy about dropping an AMP-3. I have one of those too. :)

If you do try multi-channel from the Oppo to the PDSD it'll be interesting to see what you think of the sound.
Thank you for all of the information. Yes, my question was really if the AVP or AVP2 could get the 5.1 LPCM data and do something with it. I now know the answer is nope - 5.1 LPCM is newer than the AVP/AVP2 DAC can handle. Fair enough.

And yes, I was considering moving away from my Rotel in favor for a AVP2 - I do not currently own an AVP/AVP2.

I am a big Proceed fan and have the following in my system:
CDD, PDP, PRE, AMP2, AMP3 in addition to the Rotel RSP-1069. I run the front channel pre-outs from the 1069 to the SSP pass-through on the PRE. This way I have a pure 2-channel solution and HT all together.

My interest in the AVP(1998)/AVP2(2001) was that the DAC's are much newer than my PDP(1990) and they are going relatively inexpensive on eBay. The idea was to sell the PDP and PRE and replace with an AVP/AVP2 for almost a wash. But the sticking point is integrating home theater into the picture - aka, the AVP/AVP2 would not have a SSP pass-through like the PRE. So then the question in my head became could the AVP2 replace the 1069. If I give up the Dolby HD/DTS-MA feature, than the answer is yes. I would need to buy a HDMI switcher. There is a cool Octava unit which will send the audio from the HDMI to an optical out.

My budget will not allow me to get something amazing like the Arcam AV888.

I'm not unhappy with what I have, it's just that little voice in my head that wonders how much better could it be...

"Hi my name is Tim and I'm an audioholic..." (no offense intended)
Dpphd,

Thank you for your response. I do not currently own a AVP or 2 or 2+6 for that matter. There is currently a +6 here on agon for $2K. At that price, I think I'd probably throw in the towel and go with something more modern.

From what I gather, even the DTS Core track to an AVP/AVP2 track would be an improvement over the DVD DTS; and I have read there is much debate how much better the HD/MA tracks are over the DTS Core track. So that could be an option worth testing out if I come across a great deal on a used Proceed unit.

Out of curiosity, are you using the PAV/PDSD for 2-channel work these days? I've read many people say to go this route as opposed to the AVP's for surround.

Cheers!
Thanks dtc! Yeah so the pondering becomes using the core track audio on the older proceed gear vs something newer that will at least be the proceeds equal for 2 channel sound. I hope that makes sense. And all the threads I've read says that the old proceed gear will still hold its own in this respect. The only other alternative that I can see is something like an Anthem AVM 40 - but I have not read up enough on that unit yet to get my gut feeling for it. But the price and features and sound quality seem to fit what I'm after.
db,

The Classe and Bryston would be fantastic of course, but out of my price range right now, sadly.

So - resetting my expectations then, I'm either looking at staying with my current rig or move to something like say an AVP2 or SSP600 and add a HDMI switch which sends the audio out to the PrePro. This way I get the DD/DTS core tracks for BluRay audio and otherwise my system is tops for audio. The only thing I'd be missing is the DD HD/DTS-MA. This seems very reasonable to me.

My current TV is a 1080i 42" Sony which is now 8 years old. What that dies there is no telling which way I'd go - 3D, 4K. So having the video switching external to the audio would be a benefit as I could change out the HDMI switch cheaper than the SSP.

Clearly, I have no problem with non-current equipment as long as it sounds and performs outstandingly.

Funny thing about HDMI issues - I have none with my setup: Rotel RSP-1069, PS/3, comcast box, apple tv and marantz dvd to Sony TV. The more I have been reading about issues with ssp's, I realize just how lucky I have been with zero problems.

db - where do you live? AZ by chance? There is a "db" I'm familiar with who lives there...
DB -
A different DB. :)

Oh now you are talking my language about a quality vintage device, but you have one with multi-channel input. IF I were to consider the PAV/PDSD route, do you have any advice/gotchas to watch out for?

DTC -
I probably could cable up and avoid the need for a switch:
- eliminate the Marantz DVD
- apple TV
- uses the one HDMI on the TV
- optical to the PrePro
- PS/3
- component to the TV
- optical to the PrePro
- Cable Box
- component to the TV (Do I have 2 components...gotta look)
- coax to the PrePro

I already have a Logitech Harmony, so I'm not worried about making this work for the Mrs. :)

This solution above would eliminate a AVP2 - it only has 1 optical input.

Just thinking out loud here...thanks for listening/reading.
Db,

I have a question for you that I'm sure is in the manual and if you want to send me there that is cool. But looking at pics on ebay of the pav/pdsd, it is not clear to me - how do you connect them together?

Tim
db,

Does the audio signal ride from the PAV to the PDSD via that interconnect cord? In other words, if I have an analog source connected to the PAV but the amps all connected to the PDSD how does the analog signal get to the PDSD.

And as I type this question I realize, I have no analog sources at this time. But there is always the thought of a turntable.

Tim
Db, I thought you'd bring the oppo in through the multichannel single ended connections on the pdsd. If you just want stereo just hook them up there. Without seeing all your stuff I'm not sure if you had something else already in there. Tim
Do you feel there is a difference between the pass through and a signal coming from the PAV? When a signal comes from the PAV is is it kept analog? I would think that it would be kept analog just like the multichannel inputs are. I think that is the cool thing about the PAV/pdsd is that all analog stays analog and
Only digital sources are dealt with in the digital domain.

Sorry for the iPhone accidental premature first post. :-)
