Dolby ProLogic on or off?
Hey Guys,
I can tell which is better in between pro logic or standard...How do you guys set it up? Sound like pro logic has more central vocal an when off theirs more base...

I would say on..
Standard is stereo so no matter how many channels / speaks your music has it will split them up between left and right.. Mono is like One speaker all sound no channels
Pro-Logic takes advantage of the sourround sound capabiltiy.. so when the artists make the music for example and they have a Tamboreen in the song and they only want that particular instrament to come from the front of the car it will while maybe the kick/bass drum comes from the back of the car...
Like watching a movie.. ever notice in surround sound a bullet can wisp past you and it sounds almost like it started in the front of the room and ended up going behind you ? Thats pro logic sending the sound to different speakers at different times.
where I believe stereo will just use only left and right.. not left/right/front/back/sub

I switch it off when listening to music on XM or FM radio. Seems to sound a bit better. Otherwise, on all the time.

OMGthedonny, please don't give that kind of advise, that's just horribly confusing and seriously incorrect.
Bazo, I'll do my best to help you understand. DolbyPrologic is a simulation. You are manipulating a stereo signal and splitting frequencies to widen and expand the stereo field via the ELS premium sound system, designed by Eliott Scheiner. It is one of the better simulations too, so you can see why we all debate about it being on or off.
Yatta yatta yatta, I could go on but here's the bottom line. Do YOU like it with the DP on or off, that's all that matters. I prefer off for stereo sources, until I insert a DVD-A, which will give you that true surround sound separation that we all talk about so much.
So in answer to your question, stereo sources, DP off.

I will tell you this. When im cruising with windows down listening to Techno/Trance/Hip-hop i turn off Dolby II. Why you ask? You get way more volume. When I'm cruising with windows up listening to my R&B or Jazz/Classical tracks, I turn it back on. Any of you ever fade your speakers to the rear inn Dolby II? Its mostly Echo/reverb.

Desmond (see sig) but np. I do enjoy PLII but in certain situations. Great for road trips or listening to talk radio/news/sports stations on xm or books on CD.

They are if Dolby II/DTS is on. When off there is no reverb and they play just as loud/full as the fronts in stereo. The 07-08 Stereo sounds way more "fuller" louder thean the 06 my mom once owned.

I prefer it on. You do get less volume but when I play older cd's with vinyls converted to mp3, much of the noise from the recording is diminished. Even though they are stereo recordings, they sound cleaner.
For xm or fm definitely off sounds better to me. Seems the bass tones hit a bit harder. Its a matter of preference.
It is the audio adjustment I use most and its the last in the menu. 8 clicks away. Wish it was the first.

To add a bit more, pro logic simulates surround sound. It is a remarkable technology, because it takes a recording that only has two channels and SIMULATES surround sound across multiple channels.
If you go out and buy a DVD-Audio that was actually recorded in multiple channels, you are getting true surround sound, not simulated. Optimally, you want music recorded with the intention of surround. You can also find music that has been, for lack of a better word, adapted to multiple channels (there is a bootleg DVD-Audio out there of Pink Floyd's Dark Side of the Moon, and it is amazing.)
Dolby Pro Logic really impresses me for what it does. But I am a bit of a purist, and I prefer music to be played the way it was intended when recorded. I prefer my stereo recordings to be played in stereo, and my surround music to be played in surround. Once in a while, I'll play with processed sound, but I usually like it flat (not adjusted at all on an equalizer) and unprocessed.

Ah, Para, you had me on board until you mentioned the B word, Bose. Or "blows" as we in the industry call it. "All highs, and no lows...it must be Bose". I can't say that the ELS is much better in the Car Audio arena, but as for home audio, Bose is taboo, we don't dare mention it. Bose is for people who just want sound in a room and don't care about proper sound reproduction or care how to use good electronics. A great product for the AV moron, until they realize that it can't be integrated with any other AV product! LOL. Happy Holidays all.

My name isnt para..lol. Notice my sig? But I no the saying. I've had acustimass 6 in my house for 12 yrs hooked to a sony dolby digital receiver. In a car It's awful bu I was just wondering how RL's Bose dvd-a system sounds in comparison to the 3rd gen Tl as the wattages are more fair 225 for ELS/250 for Bose.

Sorry to resurrect an old and contentious thread, but there's a bit more to be said on the "what is Dolby Pro Logic II" issue.
DPLII is really two separate things, a 2 channel -> 5.1 upmixer (simulated surround sound) AND it is a matrix encoder/decoder that can encode 4 or 5 channel sources into a 2 channel stream and then pull them back out on the decode side.
For most practical purposes in the ELS system, we're just talking about the 2c->5.1c upmixer so it is in fact not "true" surround sound. But if you could get your hands on some multi-channel audio that was encoded with DPLII it would come out with the discrete channels more or less intact. The only place you're going to run across such material is broadcast TV though, so this part is really only useful on home theatre systems.
There's more history and info on the format here: http://en.wikipedia.org/wiki/Dolby_Pro_Logic

Note that if the audio was encoded in DPLII, then the surround is no longer simulated, the multi-channel info has been encoded into the stereo signal. Similar to how analog broadcast TV is a black and white signal with color information encoded into it with a similar hack.

There are some TELARC CD's that have matrixed surround, aka Dolby Pro or II. This is the same technology used before DVD's on HiFi VHS and was real surround, although not discrete. You had objects come from behind, just not full range sound in the back channels. I think I have one or two CD's which are unlicensed surround like this, but work with Dolby decoders. Now for those of us who have or are thinking about adding a DVD player to a flip down monitor and/or the front screen, if our car has "pro-logic" setting, we should use it because it will decode the matrixed surround that all DVD players downmix into the 2 channel audio stream. It's better than just straight stereo for movies, and the best we have because there's no way to connect a digital input to any of the cars I think.

Which is all I like Bose for. My home theater hooked to my Sony DTS Receiver. I've had mine since I graduated high school and they've never blown.
