PS3/Onkyo 605/CD: Why is Multich displayed - Blu-ray Forum

Baseball3 · 05-14-2008, 12:04 AM

Playing the Drive By Truckers CD "A Blessing and a Curse" in the PS3 and wondering why is shows Multich Engaged when I switch to stereo mode. The PS3 is set as the DVD input on the Onkyo 605. The display also shows 176.4 and Multi PCM. No rear sounds at all. All replies will be appreciated! This is not a SACD.

its displayed multi channel because the receiver is getting pcm. all the decoding is done in the ps3

I figure its just cause the 605 is a BD lover

Even though clearly not MultiCh PCM that is what will be displayed. Is that what you are telling me? And, it does not sound so hot. Thanks for the reply. Trying to sort this out.

Well DVD Multich sounds a hell of a lot better than DVD Direct.

And my only choices for listening modes are those two above.

Correct. The PS3 decodes everything internally and outputs into Multichannel PCM. As a result, the receiver will only show Multichannel PCM on the display.

i dont use the ps3 for music so i cannot comment on that. but in terms of blus, i have my ps3 set to pcm and everthing in the audio selection is checked. whatever the audio on the movie soundtrack, its decoded and sent pcm. my onk 705 displays mult ch.

maybe its the listening mode your using. but since the ps3 is decoding everything, all the receiver will get is pcm (decoded dd, dts , true hd, dts ma, etc)

but it ain't multichannel at all.

if its not multichannel, that means its mono.

Stereo is multichannel...

All non-smart ass replies are appreciated! It seems that the common vernacular implies that multi-channel is more than your basic stereo. However, the fact that two is more than one and thusly by definition not mono or singular and recognized as such by both of you an opening has been made available for for each of you in next semester's advanced differential equations class.

Thanks for the help and enjoy the class. I look forward to good scores from both of you.

I'm not exactly sure what you want...It seems like you want an explanation as to why 'multichannel' shows up on the receivers display. We've explained that. How is the audio output setup on your PS3? bistream or linear PCM?

If you only want stereo to come out of your speakers, you'll have to uncheck most of the audio settings on the ps3 and switch to bitstream. This will allow you access to the receivers DSP (including stereo mode)

Is there something more that you're looking for. maybe I'm missing something here.

Manual p. 62
"For PCM 176.4/192kHz signals input through HDMI IN, only Pure Audio, Direct, and Stereo listening modes can be selected."

I am enjoying the clarity of the multi-channel stereo you made reference to in your earlier post. Most everyone when speaking of multi-channel is referring to something more than mere stereo. We all know that two is more than one and that multi is two or above but thanks, yet again, for your patient explanation. To my mind, clouded as it may be, I would have thought that perhaps something of the order of PCM Stereo would have appeared in the display. Why even have "stereo" as a listening mode since in your mind it is after all "multi-channel"? Regardless, I get it. I am getting stereo, the multi-channel sound since stereo is more than singular and to hell with the common vernacular and the usual understanding.

It seems to me that given the fact there is no use of the rear speakers that some display other than Multi would have appeared especially since only the fronts were active regardless of the fact that two while stereo is still multi.

Slec · 05-14-2008, 01:46 AM

I guess first thing I need to say is... ignore my remark about multi-channel and stereo being the same thing... you hit the nail on the head the first time, i was being a smart ass... you recognized it and I moved back to the task at hand.. apologies for muddying up the waters...

Maybe that's where the confusion is coming in on my end. The PS3 decodes all sound internally and sends out as Linear PCM. For some reason (everything I've read points to a possible hiccup in the code), when selecting the 5.1 and 7.1 settings in conjunction with output as linear PCM over HDMI, the PS3 decodes CD's into multichannel but the surrounds have no level. Kind of like a place marker is still in the signal being transmitted.

As a result you have to switch to bitstream AND uncheck the settings...

I am not about to undo the settings and switch to bitstream just to listen to a CD. I realize that stereo is a subset of multi and I will just be happy with that understanding; I suppose. Unless there is way to have a setting just for CDs. It seems with my SACD stereo discs I can do things differently. One would think that someone at Onkyo would have figured this out. Maybe I should be happy with the fact that I am getting the 176.4 kHz signal.

I haven't tried a CD, but with mp3's off the hard disk I don't change my settings. I did at first, but I'm too lazy/think its too much of a pain to change them now. So now I just play them as is... I'm ok with it.

Edit: Let me toss one in and see what happens...yep...stereo out of the two fronts.. just like with mp3s.

Slec · 05-15-2008, 01:46 AM

This got me thinking.... So if the receiver is showing multi-channel does this mean it's trying to output at Multi-channel levels. Receivers are rated for a certain output (in watts) in stereo, and a lower output when all channels are driven. Anyone?

un4gvn94538 · 05-15-2008, 02:45 AM

i think its just a ps3 thing. the way a signal is sent. on some blus and movies on the hd and also games when your using hdmi and have everything checked because we have the latest onks, the receiver will read as 7.1 pcm but not outputting it. then in order to matrix the audio like normal, we have to uncheck blah blah blah. i dont think its trying to output what its displaying so much as its just outputting what its getting. ive had audio displaying on it as 7.1 but only 5.1 coming out whithout a single noise or hiss from the surround back speakers. if it was trying to output it, it would probably have some sort of noise coming out of them when i turn the volume up. maybe im just tired and dont know what im talking about

Baseball3 · 05-16-2008, 11:53 AM

Continuing on: I noticed last night that the same CD once imported plays at 48 kHZ and the display reads MultiCh 7.1 while the actual CD is playing the display shows 176.4 kHZ and MultiCH 5.1 odd don't you think. I understand that the import settings would effect the sample rate or whatever you call it. right? In looking around at the Onkyo settings I noticed a setting for 176.4 kHZ and that I could have it set for Direct, Stereo, Last Valid and maybe something else. Worth looking into? Anyone tried this? My concern is having to change it back to Direct when playing a SACD. Maybe the other choice is MultiCh but either way the thoughts of you gurus are sought.
