I think that if you use the

QSD1 or Surround Master

you would find out that it is a QS encoded disc

Maybe the Audition script is a bit out

It is not, at least my copy (see photo above).
It is true that the scripts had been developed a lot during these years on cleaning out the decoding from artifacts, but the basic maths are the same. While the SQ/QS test i did 7 years ago were with a older script, the only decode that did match the UK Q8 was the SQ for both UK and Jap.

You're talking about The Japanese version of Atom Heart Mother - correct? Rustyandi was talking about the Japanese DSOTM...

Does your Japanese ATM have any of the additional matrix info, e.g. "2S 1 P" or "2S 4 P 4-3 W" ?

I went down to my Cave
Pulled out both LPs
The QS was marked as above
I played the SQ in QS the front is the same but the rear channels
are not separated there is a of centre decoding
But when I play SQ in TATE and QS in QSD1 perfect
I can say that there is two Quad LP. versions of Dark Side Of the Moon

Thanks Rustyandi for the clarification about DSOTM. This does fit pefectly with what i've written above: the matrix information of the stampers are different between Japan and UK, so it is a different cut, non stamper-cloning involved.

Back on the AHM topic, i've checked the Vernon site about the various quad releases of AHM and the only recut is the third Brazilian edition

Title: Atom Heart Mother (SQ quadraphonic 3rd issue)
Record Company: EMI / Harvest Records
Catalog Number: 31C 064 04550QD
Matrix Information: (side 1 / side 2)
1) 04550 1 C2 (P) 1187 200 / 04550 2 C2 (P) 1987 200 (both written)
Release Information: Third SQ quadraphonic issue.

All other AHM quad releases anywhere does have the QHVL-781* stampers, thus all these are clones of the UK version, which is SQ.
So, following the same reasoning, i can say that there is only one Quad LP version of Atom Heart Mother.

I will try them out tomorrow night
I use the Scope and my ears to test decoding
I am hoping when my granddaughter gets some time to tell me how to put
things on the net I will show the tests
It's not all roses when you get old

I played tracks From A/T/H/Mother in both systems
My first questions is WHY?
Music it is not
Track
Summer plays along until near the end then a guitar
goes solo in R/R channel
The track plays the same in both QS and SQ
when I played the QS in SQ the guitar went to the front channel
So it did not decode the same
Track
Mind your thoughts Please
there is a lot of movement around the channels
It played the same in QS and SQ
My thoughts are there is two Systems
SQ and QS Quad
If you played either Systems on the wrong Decoder you will
a surround effect
But only when played on the right Decoder
do you get a clean channel separation
The numbers on the disc are as shown on the pictures above

Old thread back. Regarding jap pressing of AHM I think there’s misinformation about decoding correctly just by the fact jap pressing have similar stamper it doesn‘t mean it is the same stamper. it was 1974 and almost everything could be done!!
Back to topics:
I never really listened carefully to this album in quad, I have both jap lp and the “sad” US Q8. I tried to understand which song has the best quad effect so I could determine which encoding was used on the japanese pressing. Winopener suggested me to try Summer ‘68 because near the end there’s an acoustic guitar going front center to rear left
I listened to the Q8 first and it is just like that, center to rear left
checked that in SQ with the Tate and as RustIandy said it goes from center to front left. Tried that again with the sansui 7001 and boom!! Front center to rear lef, so this sounds QS to me.
Now that I’ve worked a lot on auition scripts I’m very sure that a rear left signal would sound mono and oop on sq undecoded, which is different from QS, any left or right signal will play 75% left or right, in phase and out of phase. If this was a SQ stamper that guitar would play correctly in SQ.
I also did some research and there are 3 pressings of the RM version of AHM.

Maybe the first batch was SQ??
I have the “version 2” pressing.

and by the way:

As you can see the rumout area of the japanese pressing on side 2 is wider than the UK
