In Reply to: RE: Can someone define "Matrix" as used in 90's Onkyo? posted by Lesis Moon on March 18, 2009 at 07:37:03
In the 70s, analog quadraphonic sound was often delivered in matrix form ... that is four channels were encoded into two stereo channels and then decoded back into four for playback on a regular stereo turntable or tape deck.
These matrix systems used mainly out of phase signals to tell the decoder to direct the sound to the front or rear. Later home theatre receivers often provide a matrix position to simulate multichannel sound from stereo sources ... and they likely still operate on out of phase signals within the stereo source.
Is that what you were trying to say Ben? LOL

Follow Ups:
But if a two channel recording has no other encoding, does the Matrix mode change the signal delivered in to the rear speakers in any substantive way?
It depends on the source material. Some stereo recordings actually decode better than some matrix quad titles. All you can do is try. Some will do nothing, and some might be pretty cool. No way to tell but to listen.
