Logic 7® multichannel surround-sound technology has set a new standard for acoustic precision and authenticity, contributing to a completely new surround-sound experience in automobiles. Originally developed over the course of many years for professional recording studios by a team of Lexicon engineers under the leadership of acoustics guru David Griesinger, Logic 7 processing has been the first choice of discerning music lovers for their homes since the introduction of the Harman Kardon AVR 7000 audio/video receiver in 2000. Logic 7 processing became available for cars in 2001. This unique technology has become indispensable, particularly in the automotive industry, because it delivers authentic, three-dimensional listening pleasure to all seats in every car.
Always using the original recording as its benchmark, Logic 7 technology uses a sophisticated matrix and specially developed digital algorithms to transform normal two-channel stereo recordings into realistic, atmospheric multichannel surround sound. Instruments and voices are reproduced with an impressive sharpness, body and localizability, allowing even the finest details to be heard.
How does it work? Music is faithfully recorded in the sound studio on, for example, 48 tracks and is then reduced to two tracks on a normal stereo CD. Some information, but by no means all of it, is lost. Though normally imperceptible, stereo recordings still contain a great deal of spatial information from the original recording. This information is interpreted by the Logic 7 multi-channel surround-sound technology and distributed through the various channels of the Harman Kardon sound system, which has been specially tailored to the specific car model. The result is absolutely faithful to the original: The sound is distributed solely on the basis of the original intentions of the musical recording, without any artificial effects. All the system does is to reproduce the sounds that were already there.
The perceived sound source is moved away from the individual speakers, giving the impression of being in a much larger space. This opens up the soundstage and results in 360-degree sound for every passenger, no matter where he or she is sitting. An optimal result, despite the difficult acoustic conditions found in cars, is achieved.
Of course, this requires an understanding of the “secret” codes of sound engineers. And members of HARMAN, which includes Harman Kardon, Inc., have this understanding thanks to the full-process competence that comes from having a single source.
