Anyone can explain what is logic 7 in W211 and how does it function and operate?

Well, the Logic 7 is Harmon Kardons system that pretty much gives you better sound using only the speakers that you have. Meaning, if you only had two speakers, one left and one right, the LOGIC system would create a sound field wider and more open than what you really have, so the sound, in the end, would appear as you had more than two speakers. The Logic 7.1 gives your car the feel/sound of a 7 channel surround system.

Oh... Thanks for reply,
according to your msg say.."The Logic 7.1 gives your car the feel/sound of a 7 channel surround system." What does this mean by since was just only have two speakers ??

Well, your car has more than two speakers. But it gives your audio system 7 channels. Meaning, you have a 7 channel surround system in your car. When you set the radio to SURROUND, you'll notice the main sound comes from the center channel on the dash, and the rest of the sound is dispersed accordingly to either the rear speakers or the front speakers.

BOTTOM LINE: This is one of the best car audio stock systems today.

O..ic, but how does the sound spread into 7 channels; Can u describe the 7 channel inside the W211?

Hahahaha. Thanks, I just did a search.

Dude, In a really good surround stereo system, the sound just fills the car & its hard to say which speaker a particular sound comes from. Its a very natural, spacial sound. In a crappy sound system you can more easily tell "channels" & where a sound is coming from.

In its most rudimentary form, early stereo had voice coming from one channel, & music coming from the other. (Listen to an early Beatles Stereo Album that has not been remixed) ...till engineers figured out that that is NOT what NATURAL sound sounds like.

...anyway, you can not describe surround sound in a forum post. You have to sit in a car that has it & listen for a while then turn it off. You'll notice the difference. Sort of like listening to a song played on am AM station & then hearing it on an FM ststion. Same song, different sound upon the ears.

ic....... haha! thank you very much that your clearly info here, i'm understand what did you mean.

What is Surround Sound?
There are many ways to make and present a sound recording. The simplest method, and the one used in the earliest sound movies, is called monaural or simply mono. Mono means that all the sound is recorded onto one audio track or channel (a single spiraled groove in a record, for example, or a single magnetic track on tape), which is typically played on one speaker.
Two-channel recordings, in which sound is played on speakers on either side of the listener, are often referred to as stereo. This isn't entirely accurate, as stereo (or stereophonic) actual refers to a wider range of multi-channel recordings. Two-channel sound is the standard format for home stereo receivers, television and FM radio broadcasts. The simplest two-channel recordings, known as binaural recordings, are produced with two microphones set up at a live event (a concert for example) to take the place of a human's two ears. When you listen to these two channels on separate speakers, it recreates the experience of being present at the event.

Surround recordings take this idea a step further, adding more audio channels so sound comes from three or more directions. While the term "surround sound" technically refers to specific multi-channel systems designed by Dolby Laboratories, it is more commonly used as a generic term for theater and home theater multi-channel sound systems. In this article, we'll use it in this generic sense.

There are special microphones that will record surround sound (by picking up sound in three or more directions), but this is not the standard way to produce a surround soundtrack. Almost all movie surround soundtracks are created in a mixing studio. Sound editors and mixers take a number of different audio recordings -- dialogue recorded on the movie set, sound effects recorded in a dubbing studio or created on a computer, a musical score -- and decide which audio channel or channels to put them on.

In the next section, we'll learn a little bit about how surround sound was created and see how it was configured in older theaters.

A better approach to sound: Logic 7®
When the engineers at Harman Kardon set out to find ways to improve the playback of multichannel sound, they came up with significant improvements that build upon recent advancements in digital technology and take them to the next level: Logic 7.® Originally developed for high-end processors and now featured in luxury automobiles, Logic 7 processing is now part of every A/V receiver we offer. With Logic 7, proprietary digital algorithms are used to create a more cohesive and enveloping sound field from the tens of thousands of analog matrix soundtracks currently available. Logic 7 is not only capable of resolving either five or seven channels from a two-channel source; it increases the accuracy with which sounds are directed to the center and surround channels, for more precise reproduction of the original soundtrack.

Also keep in mind, the Logic 7 Harman Kardon systems installed in the NON NAV 211's do not support any DD or DTS (true surround) disks.

NAV equipt cars MAY support DD and DTS encoded disks through the NAV DVD slot as the Lexus and Cadillac XLR do.

I have a non nav car but I'm sure nav owners can confirm/deny this.

Also this link will help provide some information on new auto's that will support the above mentioned formats.
