whys ps3 saying multichannel and not 5.1

[stow123]

ive hooked my ps3 up to my amp and on the ps3 while playing commando its saying dts multichannel 48khz not dts 5.1 48khz whats multichannel mean

[kpkelley]

How are you outputing the sound? It appears that you have it set up for lpcm and not bitstream, so it wouldn't be outputing dts.

i have mine set to pcm going to my 605 and it says pcm multichannel hdmi

Ive definately set ps3 to bitstream it says dts on the amp while playing.Does anyone know what multichannel means instead of 5.1

Mine was doing that as well. I was outputting the sound via optical and had it set on linear pcm. switched it to bitstream and everything is working fine. Make sure you have bitstream selected on the which every cable you are using for audio. either hdmi or optical.

If you are using HDMI you should set it for LPCM, as the PS3 cannot bitstream High-Def audio sources.

This is correct. If you keep the PS3 set to LPCM then you will always get the best possible sound experience available on your Blu-ray. The receiver will always register it as Multichannel because the PS3 is sending the signal as PCM.

Multchannel = Uncompressed LPCM

Multichannel audio is the name for a variety of techniques for expanding and enriching the sound of audio playback by recording additional sound channels that can be reproduced on additional speakers. Surround sound refers to the application of multichannel audio to channels "surrounding" the audience (generally some combination of left surround, right surround, and back surround) as opposed to "screen channels" (center, [front] left, and [front] right).

One of the first documented uses of surround sound was implemented in 1940 for Disney's classic animation, Fantasia. Dubbed 'Fantasound' it consisted of three audio channels which were diffused (panned—initially live by an engineer) around the cinema over up to 54 speakers, which was achieved through the use of the sum and the difference of the phase of sound.

Surround sound technology is used in both cinema and "home theater" systems, games consoles and PCs (For example, Battle Gear 4 Tuned from TAITO used 5.1 channel surround sound system)[1],and a growing number of other applications.

Consumer surround sound formats include sound on videocassettes, Video DVDs, and HDTV broadcasts encoded as Dolby Pro Logic, Dolby Digital, or DTS. Other formats include the competing DVD-Audio (DVD-A) and Super Audio CD (SACD) formats; and MP3 Surround.

Theatrical film 5.1 surround formats include Dolby Digital, DTS, and Sony Dynamic Digital Sound (SDDS).

Surround sound hardware is mostly used by movie productions and sophisticated video games. However, some consumer camcorders have surround sound capability either built-in or available as an add-on. Some consumer electronic devices (AV receivers, stereos, and computer soundcards) have digital signal processors or digital audio processors built into them to simulate surround sound from stereo sources

Perhaps this will answer your question. I apologize i didn't notice that you had said DTS Multichannel in your original post.

My PS3 Reads: Multi Channel IN on games (MW2 & Saboteur)but is correct for movies??? In movies I get DTS MA DD HD, etc. I'm using HDMI.

what model ps3 do you have? kinda sounds like you have a slim and your bitstreaming to your receiver so the receiver will say truehd and dts ma for movies. if it says multi channel for games, thats also correct. games dont use true hd and dts ma. the ps3 uses lpcm audio from the disc. my receiver says the same thing when playing games.

without the benifit of actually knowing, i'm willing to bet he has a PS3 fat which means he's getting exactly what he should be getting, HD audio, decoded onboard and streamed as an LPCM to his receiver which usually will say multichannel LPCM or something to that effect.

I would think un4gvn94538 got it right about the slim. The poster says his AVR display shows HD codecs when playing movies, which can only mean he has a slim set to bitstream. The receiver would never show HD codecs if he had an older fat model.

To the OP:

This is very simple, actually. When you set your PS3 to 'bitstream', which is probably the best option for an optical connection (seriously, you need to upgrade to HDMI), your PS3 no longer is decoding the DTS stream so it doesn't know how many channels are contained. Therefore it states "multichannel" as you have experienced. As long as the little DTS light on your receiver is illuminated you will be getting the 5.1 or whatever the original DTS core track contains. Just be aware you will only be able to hear the DTS core (1.5 mbps) of any DTS-HD (MA) track via optical.

To reiterate, the PS3 displays "multichannel" when set to output via bitstream because it isn't decoding the audio stream and therefore doesn't really know how many channels are contained in it. But nothing is wrong and your player is performing as it should.

I have a question. I have a "fat" hooked up to my main set up the right way, LPCM, HDMI to yamaha receiver. I have a "slim" that is hooked up via optical to an older Kenwood receiver( NO HD audio or HDMI input) should the slim be set to bitstream or LPCM?

Bitstream. PCM is limited to stereo over optical. Bitstream will send encoded DD 5.1 and DTS to your receiver.

ummm...no. (but my comments are still valid. )

depends on if your yamaha receiver can decode DTS-HD (MA) and Dolby TrueHD. if yes, I would switch the slim for the fat and set the slim to bitstream to the Yamaha via HDMI. either way, bitstream to the Kenwood is correct.

[BLURAYSONYES]

Isnt the new slim PS3 can do bitstream through HDMI? I know for the fact that the fat PS3 will only show LPCM or multich through HDMI unless used by optical cable.
