Matrix Quad CD's

EV-4 Matrix was also referred to as the Feldman/Fixler Matrix.

Was EV-4 encoding / decoding any good. I don’t recall any sophisticated decoders with logic ever being released.

I used a EVX-44 back in the day but eventually moved up to a Lafayette full logic decoder. Sometime in the 80's I picked up three EVX-44's (probably on eBay?) and eventually sold two. I still have one NOS EVX-44 in storage - if anyone is interested, make me an offer I can't refuse.

I'll have to look on Discogs, the amazon UK seller contacted me and said sorry the last one had "I Couldn't Believe My Eyes" gone!

Correction this album may be ...EV-4.
Either way a candidate for the Surround Master 's 'Involve' setting.

I found one last night on Discogs after the amazon seller phoned me to say he hadn't got a copy left (he was interested that it was a hidden Quad!), the Discogs listing said sealed, so might even be new, should arrive in the next day or so.

Oh , that's great. I know all of the Bluesway artists that had QS encoding , and pickings are slim for CD.

I’ve added this to my original post of November 1, 2006. Wow, almost 20 years ago. I bought the older CD, but it didn’t convert into QS Quad. As far as I could tell.

Note 3-7-25 Not Quad:

Tommy - Original Soundtrack Recording; Polydor 841 121-2
{Long rumored to be QS encoded. Consensus is that LP and CD's are
merely stereo}

Please see the “Definitely Not Quad” section at bottom of page:

I can't vouch for that CD version , but it's my opinion the 1975 vinyl is QS encoded.
I know this is contrary to others who say it's stereo .

 

[fizzywiggs41]

And I recently aquired this via Amazon.

SunRa Space Is The Place , previously this album was on Blue Thumb Records.

Its Interesting to note that this disc ' Space Is The Place has been returned to its rightful place on Impulse', liner notes.

This was my experience, such as it was, during the Quad era. “Tommy” the movie came out near my 16th birthday. I was able to see it in a “Quadraphonic” version at its Bay Area premiere at The Paramount Theater, in Oakland, California. The theater was setup with Sansui equipment. I bought the record when it first came out. I don’t remember anything about the record necessarily being “Quad.” Although, if I’m remembering correct, the Sansui QS logo in small print was somewhere on the outer jacket. But, that could have been simply artwork for the movie that made it on the record jacket. I don’t know.

I noticed that the record sounded more dynamic, and it did seem to have “Quad” like effects, sort of, in parts. But, this was playing it through an SQ decoder, which also didn’t have logic decoding, as far as I know. I still have the decoder box.

So, it could have just picked up some phase information from the stereo mastering. I don’t know. If it was released in QS Quad, I’m speculating that maybe some initial copies of the record in 1975 might have been QS. And subsequent copies later were just the stereo versions. That’s the most optimistic thought on the matter that I would venture a wild guess.

We do know that in order to not freak out the general record buying populace at the time, that many QS Quad releases were “secret quads” according to Billboard magazine at the time.

So, I don’t know. I certainly heard the Quadraphonic effect in the theater in Oakland, that was setup for it. But, the record I had at the time, running it through an SQ decoder, as dynamic as I enjoyed the sound, I can’t say it was Quad. It certainly didn’t sound like the movie theater experience of it.

Just a note. I did manage to get a copy of the original version of the CD and ran a QS script on it. It didn’t seem to decode Quad. Bummer. Certainly worth trying to find stuff though.

The 2014 steelbook blu ray of the film has both the original "quintophonic" 5.0 and 5.1 lossless audio, if you want to re-live the visual as well as audio experience from 50 years ago.

Cheap as breakfast, brand new. Highly recommended.

The original 35mm magnetic prints of Tommy were a hybrid of discrete and QS. There's a very prominent QS logo in the end credits because the left and right magnetic tracks on the film were QS encoded while the center channel track was...well, the center channel. Theaters that sprung for the QS decoders and had the speakers wired correctly could get full quintophonic sound (hard center and QS-encoded corners) while other theaters could simply run the same print as then-standard LCRS, using the normal surround (or "effects" as the old-timers call it) track on the film, which wasn't used at all for quint playback.

As far as I know, the only other film using the same system was Ken Russell's next one, Lisztomania.

Thanks! I was wondering how they did 5.0 Quad at the time.
