A place for interesting quad encode/ decode tech articles

Dear All

I have a ton of background research stuff I read before going nuts to design Involve encode/ decode. Here is one I unearthed from my home desk a few days ago.

I thought this could be a good place to put other similar research/ discussion articles to improve our general pool of knowledge

Enjoy the read, I will ask questions and mark you later.

A 4-3-4 implementation of QS is briefly mentioned in FIG. 8 (b).

You may go ahead and mark me "failed". lol. I haven't owned a Sansui in 50 years or the other QS capable brands.
But is interesting and a good reference!

There are many errors in that article. I posted about it before. When I first read the article I didn't understand it, that was because the author didn't know what he was talking about! They couldn't even copy the CBS schematic correctly!

What it does is act as an SQ encoder (forward oriented) placing sounds panned hard L and R into the rear (centre remains upfront). It turns stereo into SQ which can then be decoded.

That was thanks to our very own Sonik Wiz published years ago in the MCS Review.

What does QS have to do with it? The article is about SQ, reading the entire article the author has confused the two. That is (fig. 8) the weirdest speaker arrangement I've ever seen. It must have been devised by Bose (direct/reflecting). It would be better to toe them outwards.
