what audio settings for blu-ray

NeilGabriel

I picked up the new oppo br player and like it very much...no problems after a dozen or so movies other than it skips past menus once in a while..

can someone set me straight...I use the analog 5.1 outputs on the dvdp into my receiver and am unclear when to use bitstream v. pcm output from the DVD player.

Something I read seemed to say you used bitstream for some of the new audio formats and pcm for others....I thought bitstream was for digital and not analog outputs?

Thanks guys...and ladies

If you are using the analog outputs from the Oppo to your AVR - then those things 'digital' - bitstream vs pcm are not a factor - cuz you are connected via analog to your AVR.

The debate rages as to whether it is 'better' to bitstream from the source player to your avr for decoding the lossless advanced audio tracks, or to justl let the player do it.

Bitstreaming and PCM is all in the digital domain.

Bitstreaming is like saying send the 'zipped' audio file digitally to your AVR where the AVR will 'unzip' it.

PCM is like saying let the player 'unzip' the audio and send it as a fully expanded file to your AVR.

But again, since you are connected via analog outputs, the Oppo is reading the digital source audio, 'unzipping' the lossless audio tracks (although some blu rays just have the fully PCM 'unzipped' audio on them and don't have any compressed audio to 'unzip') and then converting to analog.

The question there is - which device in your system has the better DACS? The Oppo or your AVR?

You may want to try connecting your Oppo to your AVR with the free 6ft HDMI cable that came with it and do a comparison of the audio yourself to decide what you think sounds better.

+1 as he pretty much summed it up for you. Also depending what the settings are at (96khz/etc), not all AVR's are compatible with that type of signal but you'll see in your options menu that you can downgrade it for compatibility with older AVR's.

I use the analog inputs because the avr has no hdmi ...that is why I waited for a good BRP with on board decoding..

thanks a lot....

I just installed an Oppo BDP83 last night so the manual is still in my head. While my AVR (Sony DA7100ES) has 2 HDMI inputs, it does not decode the latest audio zip files, so the Oppo unzips the audio into LPCM over HDMI. At first I was wondering why the AVR said the data is LPCM at 48KHz since I set the Oppo at 96K. That was the setting I used for my Sony 9100ES DVD player sending the digital audio over the Sony Ilink (fireware) digital connection, and there was no issue at that time.

Anyway, after going to the Oppo manual last night, it states the settings of 96K and 192K are only for the fiber or coax digital connection.

I have to admit I am impressed at how much better the Bluray sounds over regular DVD. I watched my referance DVD (T3) in Bluray last night, and there is so much more detail and openness in the sound. The in-your-face audio is similar, but the background sounds are just so much more revealing and better.
