panasonic dmp bd55 selecting 5.1 or 7.1 analog matter?

chip1,

First off, test tones aside, have you tried playing a disc and, if so, how does it sound?

The player outputs can only be lowered, not raised. If you have the levels set to 0 and are getting virtually no audio, then, the problem has to be (A) a bad player, or (B) the level trims in your receiver are too low. While most AVRs/prepros cannot process audio from the analog inputs, they usually can control the output levels and do so independent of the output levels for digital sources. I am guessing that your prepro has the levels for analog channels turned way down.

The sub definitely needs to be boosted in your processor. LFE is recorded 10db low on purpose and needs to be boosted back up. If you set any speakers to small in the player, the sub is dropped by another 5db and you will need to boost the .1 channel by 15db to get proper bass response. Many processors have a setting specifically for the analog subwoofer boost.

btw, you don't need to set the digital outputs to PCM. That setting has no effect on internal player decoding with the BD55.

I'm not familiar with your Bryston SP2. But, from what I can see on line, it's obviously a powerful processor. So, unless you have a faulty BD55, you ought to be able to get full, excellent sound with your prepro.

hello, bislander

thanks for your great input really appreciate it.

ran some more test i'm getting test tone from all my speakers know in the 5.1 configuration. i also realized that the test tones can only be lowered not raised.

my pre/pro has only a bypass analogue 5.1 inputs i reset the audio output back to bitstream and then listen to ironman again and it sounded a little better but not to my satisfaction.

i will be contacting bryston regarding the analogue outputs to see if they have another reamdy for this delima of mine.

the panny 55k sounds awesome in dolby digital and dts and i check the audio status of the player when playing blu-ray and it's telling me that it's playing dolby true hd.

again thanks for the info if you run into any another info that can help me resolve this issue of mine please let me know.

thanks, chip1

Again, changing that setting has no effect on the track that gets decoded for analog output. If it sounds better one way, it's probably wishful thinking.

I looked at the manual, which is rather sparse, just 19 pages. It says you can set channel levels for each source, but it is unclear to me whether 5.1 analog bypass counts as a source. I'd try increasing the channel output levels when the 5.1 bypass is engaged to see whether that helps.

That's what it is playing but not what is being output over an optical connection. The player outputs a legacy DD or DTS track in that case. But those tracks are encoded at higher bit rates than you get on DVD and they sound great. Some people say those tracks are as good as lossless and I tend to agree.
