Over the years, I've seen images of (usually LPs) labels that state the album is matrix encoded, but they don't state SQ, QS/RM or Stereo-4.
Perhaps the record maker was just trying to cash in on the Quad market without having to pay any kind of royalty.
Has there been any accounting of what these matrix systems were (close to QS, but different enough to not infringe on QS IP protections)?
