That CD-4 format for quadraphonic sound confused me. I was thinking you were talking about CDs that used quadraphonic sound. But I digress on that one.

[@jerrywcarman1483]

If you were to bring quad back you would have to do it in the form of the CD. Any attempt do it on vinyl is doomed to failure. I don't care if it's SQ, QS, CD-4, or whatever, it wasn't what it was cracked up to be. Q8 for all practical purposes is kaput. It failed on vinyl before, and it'll fail again.

I think the real reason why quadrophonic didn't make it was because they were six competing formats. That overcrowded the market. If qs would have survived somehow I think quadrophonic would have been a thing for much longer. And I think qs could make a comeback.

[@That_AMC_Guy]

That might have pissed a few people off, but I don't think that's the reason Quad failed. Personally, I think it "failed" because the record companies quit making Quad product. The heyday of Quad was 1972 through 1975. Heck, even DVD-HD had more years on the shelf than that!

[@VinylPro]

[@Oystein87]

I would rather have a good stereo recording played back on a proper setup than any quad stuff. If the setup (and recording) is good then it sounds almost like a 3D sound bubble with just 2 channel stereo anyway. Proper stereo imaging is awesome

[@Coneman3]

Yes, better formats rarely catch in unless the industry wants them (like CD)

[@rickcole6990]

Philips compact cassette wouldn't bulge because side 2 would become the other 2 channels of a Quad mix. So if the cassette was made for 4 channels it would be only good for that because side 1 wouldn't sound right in regular Stereo and side 2 would play backwards.

[@That_AMC_Guy]

I specifically collect Quadraphonic gear and software. I have well over 650 Quad 8-tracks, many Quad Reels and roughly 100 Quad LP's. I only collect the good stuff: pop, rock, soul, country, big band.... no classical longhair stuff for me! I've roughly 80 Quadradiscs, maybe a dozen or so that came only from Japan. It took me a few years of on again, off again experimenting with CD-4 to get it working correctly, but thankfully now I can just put a record on and enjoy it. CD-4 is by far the best Quad LP format. UD-4 (sometimes referred to as UHJ) hardly had any albums released in that format. I think there's less than 12 and were mostly or only sold in Japan. QS is probably my next favorite format. It gives a good presentation and, when compared to it's discrete tape counterpart; you can pretty much say that the QS system does a half-decent job of trying to replicate what the discrete tape sounds like. QS can definitely separate the four channels, but one thing it has issue with is panning effects. The way the matrix is written, it will cancel itself if it tries to move a sound from one speaker to another. It's great at ping-pong Quad, where a sound will POP out of one speaker, but a smooth transition will cancel out at a certain point. SQ is my least favorite - - and I have a Tate 101a! I used to question whether or not an album that was available in SQ and discrete tape had the same mixdown session because they do not sound alike at all. And I was right!! Some SQ discs have completely different mixes because the SQ system is so limited on what it can do, they made more discrete mixes on tape to compensate. SQ was designed to even be MONO compatible (don't ask me why!) which I think hurt the matrix even more. Because of this, for most of SQ's life, the mixing handbook explicitly stated DO NOT MIX ANY SOUND SOURCE IN THE CENTER BACK POSITION. If played in mono, that position is 180 degrees out of phase to the front channels and will cancel itself out entirely. SQ can only do four-corner Quad if something is panning or ping-ponging around the room. Generally, when a song is playing and there's a lot going on, the matrix collapses and you get more of a "Super Stereo" than anything. The only way I can describe it is like You get a Front Left and Front Right, but instead of Back channels, you get more of a Side Left and Side Right. Suffice to say, SQ was never able to impress me and I have the fewest SQ discs in my collection. Some folks have managed to write computer programs that get the most out of SQ, but every one I've heard has weird artifacts and distortions that annoy me. Sure, they get the separation they were after, but almost at the cost of ruining the music.

Here's a little known fact: Dolby Pro Logic II is actually accidentally backwards compatible with the Electro-Voice EV-4 (Or Stereo-4) and the Sansui QS Regular Matrix (RM) standard (EV-4 is based on RM).

[@randallslinkard1819]

In my view, all this surround sound is Matrix

[@seansands424]

Surround sound or Dolby pro logic is not a true quadraphonic it is just two stereos, quadraphonic is an actual 4 channel sound i.e. drums coming out off one speaker guitar out another the voice out another synch or piano out off the forth speaker

song of the day ob-la-di, ob-la-da - the beatles

[@peckishere]

I'm a big fan of quadraphonic records / sound. I've collected quite a few quadraphonic records over the years and I have a 70s receiver made by Trio (Kenwood) that has a SQ, QS and CD-4 decoders / demodulators built in. Unfortunately the SQ and QS decoders of the era just weren't fit for purpose and lacked good channel separation, however I have a modern SQ and QS decoder made by Involve Audio that gives extremely good channel separation that gives near discrete levels of channel separation. The biggest achievement you can obtain when collecting quadraphonic records is getting a CD-4 demodulator to actually work due to needing a compatible cartridge and stylus that is perfectly aligned to track the high frequency subcarrier signal in the grooves. I think its really cool that major albums of the early 70s like Pink Floyd's Dark Side of The Moon and Mike Oldfeild's Tubular Bells were intended for quadraphonic reproduction but its the Stereo mixes that inevitably became the ones that people came to know and love. Thankfully some quadraphonic recordings of the time are available to listen to digitally via downloads or physical media such as SACD, DVD-A, DVD and Blu Ray Audio

[@Marianne69420]

I'll add that quadraphonic vinyls aren't necessarily useless. I have a quadraphonic rip of Pink Floyd - Wish You Were Here on my computer (digitalized) and even without a quadra setup, you can absolutely hear the amount of difference versus his stereo counterpart. The sound is way more detailed and has a way better audio separation/soundstage

[@Musicradio77Network]

I have my Sony SQ decoder which is an SQD-1000 and it still works, and it’s compatible of listening to SQ records, and also plays movies on DVD, Blu-Ray and digital depending on the source like a Dolby 5.1 surround sound One of my favorite test setups for quadraphonic sound was “Revolution 9” from the “White Album” by the Beatles. It was not a song, it was just a potpourri of sounds and music thrown into a huge mess for a listener to test the speakers on all 4 channels. I tested “Revolution 9” on an SQ decoder, and it blows me away. I also tested any sound from one of the Motown albums using my SQ decoder and it sounds great on all 4 speakers. I did not know Motown never put out quadraphonic albums in the 1970’s.

I also tested out “Revolution 9” from the Beatles’ “White Album” using all four speakers with an SQ decoder and it definitely blows my mind where it goes over around the four speakers both front and rear.

That memory is etched in my mind.

[@senorverde09]

Actually with matrixed records you *do* hear the back channels when listening to it in stereo. Matrixing just mixes the four channels down to two in an algebraic fashion (using signal inversion and phase shifting). This is entirely done in the audio spectrum. With SQ the rear information sits in the center when played in stereo. In QS the rear information sits 'outside' of the front information making the whole thing sound wider when played back in stereo.

[@That_AMC_Guy]

There is an anecdote about 5.1 "surround sound" that I love to tell. 5.1 for all intents and purposes was "invented" by Brad Miller. Brad Miller was a major proponent of Quad sound back in the 1970's and was the man behind The Mystic Moods orchestra, Mobile Fidelity Sound Labs and a number of Railroad and Rainstorm sound effect records. In the 80's when he was the main man at Digital Theatre Systems (DTS) he figured that was a good opportunity to bring back Quadraphonic sound, since now it could be done digitally, on CD without much fuss. When he approached several Record Companies with the idea, they all squirmed and balked at the idea claiming to not want a repeat of the "failure" of Quad in the 70's. Brad, being the shrewd negotiator that he was, instead devised a 6-channel system recalling the early 60's 3-channel stereo ideology and summing bass to a subwoofer since, some claim, that low frequency bass sounds are omni-directional. Thus, he begat 5.1 which the record companies completely ate up as the newest, next big thing to come in the audio world. The joke was on them however, since the first releases to come from DTS were digital versions of older, Quadraphonic albums merely with a faked center and subwoofer channel. Also, the compact disc was originally imagined with a 4-channel mode, however it was never explored beyond it's original idea and no CD-player was ever equipped thusly. It's also unknown how the CD would have allowed for more than 2 channels of audio. Some speculate that the disc would either rotate slower, thus, halving it's play time OR the sampling would be downgraded to 22khz and the number of channels doubled.

One thing that is noteworthy in discussing quadraphonic sound is that a number of FM stations were experimenting with quadraphonic radio broadcasting. The Independent Broadcasting Authority Britain’s regulatory body that oversaw private sector broadcasting at the time was working on a standardized system for these radio broadcasts.

[@markmooch]

What Happened?

[@adaum4534]

@@markmooch AFAIK, Quad FM was only available in a few select US cities. It failed because the FCC allowed for the marketplace to pick a winner in terms of the different formats - it was a mad house and basically none of them won. My 1970’s JVC receiver has an FM detector OUT. It sends a still modulated FM signal out to a separate Quad decoder. The you attach its 4 channel output to those 4 RCA’s. That way you use the FM dial on the front panel to tune, but get the FM Quad signal decoded to listen to even though it does not have an FM Quad decoder built in. Like an effects loop using FM out to Quad in. Many people also don’t know but AM came out with a couple mono compatible stereo versions that were superior to FM! It also died because FCC let the marketplace pick the winner. They thought it would be like 33/45 or VHS/ Beta solution.

The two channels on a record groove are achieved on the two sides of the groove that have a different shape and sit at a 45 degrees angle to the horizontal. An "up and down" modulation would wear out very quickly and it would be much harder to track. 🙂

You are absolutly right. In fact they thought about doing it that way left and right and up and down and changed their mind and used the one you mentioned.

Growing up I had a receiver that had CD-4.. and being a child of the 1980s I had always figured that was some early Compact Disk thing as I didn't know about Quadraphonic until just a few years ago.

[@jerryneubauer1484]

Jared, I have about a dozen or so Quadraphonic Records...most are from the band Chicago...and Loggins and Messina...Columbia Records in the early 70's had this option in addition to buying the standard stereo versions of those albums..

[@fuq_owen6924]

Song of the day: Touch me - the Doors Also, does anyone know when the SQ versions of Dark Side of the Moon were pressed.

[@jefrywashere8755]

I have DSOTM but it's stereo...

[@notmanatee2445]

6:59 I want that record! But in stereo instead of quad. Can you do videos on records of musical film soundtracks?

[@JackDaniel617]

I have the same Iron Butterfly record, it's old as dirt and sounds awesome!

[@shawnschwartz6884]

I've got many quad discs. You can connect your turntable to a modern surround system and play back the SQ, and QS discs with DTS NEO:6 to get a pretty good decode. QS discs work the best and sound nearly as good with NEO:6 as they do with a proper decoder. SQ discs work pretty well but its a little less discreet.

2 quad records in my collection ... Pink Floyd DSoTM and (the classic, and surprisingly not mentioned) Quadrophenia by The Who

[@metoo5159]

Side note. It wasn't really necessary to play CD-4 records with a Shibata stylus to capture the information to decode the channels. It was the frequency response of the phono cartridge itself that was important. Back in the day the Brookyln based "Grado Labs" made phono cartridges that went well into that 50Khz range that was needed and they were toted as CD-4 capable and yet they all had elliptical stylus shapes.

You have a great voice for being a radio or TV announcer!

[@dcassus]

Thanks for making me feel 100 years old by dropping that the mainstream days of Evanescence remind you of your CHILDHOOD.

[@paul8926]

Quadraphonic pretty much paved the way to Dolby Atmos. 👍🏼

[@WVMothman]

I have a Ten Years After vinyl in quadrophinc, it has a unique sound I'll give it that. On a regular 2 channel stereo from the 70's it's like they tried to fill up the sound space with as many instruments as possible to create the effect.

[@Techcraft15]

Very informative video! I have a 70s Sq-setup myself... But sadly... The SQ standard is not as spectacular, as it seems... The difference bitween the front and the rear speakers is very minimalistic. But I still think the idea and the physics behind the system is amazing!

[@indevelopment3453]

i've got a project 3/popular science one called "Test Record" (to set up/calibrate/check out your quadraphonic system) from 1974 (Australian pressing). By the looks of the catalogue number it is in the SQ format.

[@4623620]

As far as I know the drawing at 01:50 is based on a slight mistake. For the best experience of the stereo effect, the speaker and listener placement should be so that the intersection of the speakers centrelines is in front of the listener, not at the spot where he is. 🖖😎👍

[@nelson1220]

The best quad I ever heard was on a four channel reel to reel tape. True quad

[@NoahWilson98]

Wow great detailed video!

[@rogerking7258]

I'm still using my 1976 Rotel RX-802 receiver. This doesn't have a built in decoder, but it does have a speaker switch position that provides some quadraphonic effect. Basically it connects the rear speakers across (I think) the positive terminals for the front speakers. The effect of this is to send signals that are out of phase between the channels to the rear speakers only. Since a lot of this out of phase sound is often echoes it does actually open up the sound stage a surprising amount. It works quite well with normal stereo records, but if you play a quadraphonic record of the SQ or QS systems the effect is much more marked since those systems deliberately exploited out of phase sound to allow a decoder to separate each channel out. Of course it is nowhere near as good as using the correct decoder but it's very cheap! Decent quad systems in the 1970s could sound quite good, but as you say - the complication put people off. This is well demonstrated today by the way that the vast majority get their music through dreadful sounding MP3 files simply because it requires no effort. Ease of use will always win over quality for the vast majority of consumers, whether they're buying music, cars or just about anything.

Song of the day: Sugarcubes - Birthday (Sugarcubes were the band that first brought Bjork to the attention of the international public) OR Bjork - Play Dead (probably my favorite song of all time) OR Suede - Europe is our Playground (the version that is featured on their amazing B.Sides album Sci-fi Lullabies

[@capitolemiproducer]

I was a quad freak in high school. Firstly, I hated SQ mainly because the rear info was put at 10 and 2 o'clock barely audible. CD4 was the bomb, but not everyone could afford a CD4 turntable. 8 tracks were usually muddy and reel to reels lacked the high end. QS. worked pretty good and your present surround sound will decode it correctly, which segues to my finally subject. The first CD pressing of Carole King's "Music" (KE34949) was accidental mastered with the original ODE QS tape. So you can hear it in quad, minus the vinyl surface noise

[@aussierob7177]

If you can cancel the "cross talk" signal from the two stereo speakers you end up with a three dimensional sound stage where the walls of the listening room "disappear" and sound is all around you, just like a real performance.

[@senorverde09]

Actually they did that during the early days of quad. The Hafler Circuit parallels a third speaker across the positive terminals of two normal stereo speakers so that it plays the stereo difference (left minus right/right minus left) in a stereo recording. Any information yielding no stereo difference (i.e. center panned things like vocals) would remain in the front.

[@stevebennett9750]

Never got into quad on vinyl, but do have quad 8 track and reel to reel set up. Also quad albums reissued on SACD.

Song of the Day - Hocus Pocus by Focus

[@jesusgavemeaids]

I have a CD (& there are others too) that was mixed in surround sound. I can see why they didn't take off... Unfortunately I've only heard it on one of those crappy cheap surround systems with those tiny little speakers, so I don't know how good it sounds. The stereo version is awesome though.

[@jamesbennett9620]

I bought all of the Barbra Streisand quadraphonic LPs because I understand they were done in completely different recording sessions. So that will probably give some vocal and interpretive differences. Just to hear those differences will playing the quad albums on my stereo turntable be sufficient?

[@doobiz]

There is a few Quadraphonic Facebook groups also,"Quadraphonic And Surround Sound Audio" and "Quad Traders". They have released a lot of the Quad albums on SACD, DVD and Blu Ray too you can play with modern surround set-ups there is also a lot of 5.1 music out there.

[@stephenemmett9753]

Wa-hey! I just got mentioned in this video! Thanks a lot, Jarrett (aka Vinyl Eyezz)!

[@vinyleyezz]

No problem Stephen! Thanks for watching!

[@J.S.3259]

I have 2 Miles Davis quad vinyls: Live-Evil and Bitches Brew. Live-Evil is a completely different mix. Don’t have a quad system, but they still sound great

[@michaelszczys8316]

I remember quad reel to reel tapes, quad 8- tracks ( I have player and a few tapes ) but I don't remember much about quad records. It seems weird to think of that kind of sound in a mechanical record and groove but I do know of a record phenomenon I discovered. I found with stereo tapes that if you ran the channels together without a ground then you would somehow hear strange tracks of the recording. I discovered it with the Beatles - White album and the song ' Birthday '. If you ran the channels together you would hear the vocals, particularly the background vocals extra loudly. The stereo recording of Van Halen - Beautiful Girls would give you only about 5% vocal volume with about 95% Eddie's guitar. Rolling Stones recordings mostly gave you background singing and rhythm tracks. I found this track separation would also occur using a RECORD and thought it amazing that so much separation could be achieved through a mechanical sound format.

i still have my folks' old quadrophonic reciever with an internal decoder. they didn't have a compatible turntable though (shrugs) so i never got to enjoy it. I have all 4 speakers too. Still, it's nice to know what the little buttons like "SQ" or "discrete" meant. It covered multiple formats. I wonder why they didn't get the turntable. It was from SEARS so it was probably rebranded. i think it needs a recapping on at least a good recapping, or at least on one channel, but it worked well last time i had it hooked up. This vid gave me just what i wanted to know, thanks!

[@J.Christ-man]

I grew up with quadraphonic in my house as my father was a collector of all this gear and all other formats of quadraphonic music. And still to this day I use the same equipment and blow people's minds and ears when I demonstrate it to them. Now my kids can enjoy hearing what I grew up with. Don't get me wrong, 2 channel sound is fine but when you hear sound all around you for so many years and you hear a 2 channel system,🤔 there's just something missing... 2 channel music worked well into the Sansui Qsd-1 in the synthesizer mode and Tate 101 for the SQ records 👌 Great topic that seams to get no mention anymore and yes is very important to the development of the systems used today.👍😎

[@drandom313]

Thank you so much for this info. I recently bought a quadraphonic record by mistake, I don’t have the decoder & speakers obviously but I wasn’t sure if I needed a special stylus for it. It’s a SQ record & it plays fine.

[@berkkarsi]

Hey Vinyl Eyezz, are you planning to buy 2 more speakers and put them on each corner of your room to get a quadrophonic setup?

[@yambo59]

Lets not forget Elvis Presleys ground breaking 1973 Aloha Hawaii concert that was the first to ever be broadcast worldwide on television and was available in stereo LP as well as in "Quadradisc"-!!
