LOGIC 7
LOGIC7 is a registered trademark of Lexicon, Inc., a company of the Harman International Group. It was especially developed for applications in motor vehicles.
LOGIC7 is a sound system that creates a 7-channel surround sound from 2-channel audio sources (radio, CD, CC). The incoming stereo signals are decoded in the digital sound processor (DSP), distributed over 7 channels and remixed. The entire transmission width is used on each channel, thus creating perfect surround sound that gives the listener the impression of being in the middle of the space.
