bluray hookup to receiver

[jjclecky]

Hello all I have a onkyo 506 pass thru receiver and a panny dmp bd30 bluray.I have it hooked up from bluray hdmi for video and fiber optic cable for sound, I am being told I would get better sound if I used a composite audio cable form surround 5.1 output from my bluray player to analog multichannel input on my receiver is this a fact? would I have to remove the digital audio cable that I have installed right now? and if I would get better sound can you recommend 5.1 composite audio cable. the reason I am being told this is because my receiver is only a pass thru.

What I think you are referring to is an analog multichannel input which a 506 does not have. So your best setup is the one you are using which is the digital input. The reason you were probably told this would be to take advantage of the lossless codec's like true hd and dts master which your player can decode but you have no way to output with that model reciever.

if I was to upgrade my avr do you really think I would see a noticeable difference in audio?

Hi, Craig. The 506 actually does have those.

To the OP - you can always try the multichannel analog connections, and it only costs you time if you have the cables already. I think that the digital connection that you are using right now has great sound, though.

Sorry Adam I guess the image that I found here http://www.amazon.com/gp/customer-media/product-gallery/B0015M4G5C?ie=UTF8&index=2 was incorrect. Thank you for pointing that out and sorry jjclecky for nearly steering you wrong.

Hey, no worries! That image actually is correct, but it's not obvious when the image is small and blurry like that. The "DVD" input has 7.1 analog inputs.

Instead of using composite cabels, I would just buy two pair of Composite cables (which are rated at 75ohms) just hook up the corresponding output of the player to the multichannel input of the reciever. Select your Multichannel to hear the sound (instead of DVD or whatever else you have) go to your players setup menu and select PCM (not bitstream) and then adjust the levels for each speaker in the Bluray players audio setup with a sound meter and don't forget that the player will handle bass management and not the reciever, so adjust that in the player accordingly.

When I had mine hooked up to my Denon 4802 I had to set my Sony 300 bass to the highest it would go to get just decent bass from movies

and yes you will notice a difference by using lossless audio over compressed using optical. With optical you are limted to a 1.5Mbps compressed audio signal, with using the analog outputs from the player you get what the disc audio engineers encoded the lossless at (which can be 8 times better than compressed)

I have that receiver, and IIRC, the adjustments available for the multichannel inputs are pretty limited. I think its limited to level-matching. So, using this input would by-pass any Audessey processing, bass management and delay settings. This could (and probably will) degrade sound quality. I haven't directly compared DD and the analog inputs as I don't have a source that outputs 7.1 analog so this is purely conjecture. The cables are cheap and it won't take too much time to compare, but this is a significant trade-off I think you should be aware of and factor into your evaluation if you decide to test the 7.1 channel inputs.

I was wondering if I have my panny bluray settings correct? as of now I have it set on bitstream,being that my receiver (onkyo 506) doesnt decode any new formats should I set my panny bluray (dmp-bd30) to PCM? is there a sound difference between bitstream and pcm?

It's very easy to switch back and forth between the two and check it out so that you know for yourself, but I firmly believe that you'll want to keep it on bitstream. The new formats won't be sent by PCM over an optical or coax connection - you need HDMI audio processing to get those digitally. When you switch to PCM, you won't get Dolby Digital or DTS anymore. It will be (I believe) matrixed surround like Dolby Pro-Logic.

If you have some component video cables you can use those for the analog in's and out's. No point in buying some more cables if you already have some.

Opps I just reread my post, I meant to type buy two pairs of component (not composite) sorry for any confusion. Can't edit it (I hate the edit feature of this forum, why does it time out unlike other forums, where you can edit at any time.
