I can only imagine how amazing Floyd and Sabbath sound in quad.

Song of the day: When we was Fab - George Harrison

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.

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.

Song of the day I'm only sleeping - The beatles

Side note: not every record groove goes from outside to inside. In fact, right behind you, hanging on the wall is "Lazaretto" which actually have a-side going from inside to outside (BTW this record got some pretty interesting trivia on technical side).

Song of the day: Bridge over troubled water by Simon and Garfunkel.

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). One of the best examples you can try out is Enoch Light's Spaced Out album, or any record from Project 3 records. vwestlife pointed this out on one of this videos years ago.

I’m so happy you were able to use the “Company” quad LP I sent you last year!!

*never burned a pizza* "Right. And I have a girlfriend..." Song of the day: Calling Occupants of Interplanetary Craft - Klaatu

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

I remember hearing Chicago's wishing you were here in quadraphonic in the 70's ,the song begins with ocean waves and in quad it sounded as if you were standing in the water about say 10 feet from the shore line, you could hear the waves coming at you on the front speakers then pass you and then breaking on the shoreline on the rear speakers behind you. Also each instrument came out of it's own speaker ,cool stuff.

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

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.

Song of the day: When the levee breaks - Led Zeppelin

I just happened to accidentally buy one of these that is called “An introduction to the world of SQ Quadraphonic sound” that’s one big mix of artists that seems to be in pretty good condition. It’s got this whole intro sequence

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.

Super wild concept, love your videos on vinyl man

As always.....informative! Thanks!

Song of the day: 21st Century Man - Electric Light Orchestra

Very cool vid, dude. I never owned a quad but my friends' older brother had a Pioneer set up. He had a copy of one of my fav Aerosmith lps. Rocks. We had the blacklight on and the strobe going and when Back In The Saddle came on I could hear the horse galloping in the background. With the quad it sound like it was galloping around the room. That memory is etched in my mind.

Song of the Day: "Teenage Riot" - Sonic Youth

This was a great video. Been waiting for this brother. Thank you. Wow, I never knew how technical and details vinyl records were prior to your channel. :)

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.

When I was around 14 In 1973, our Teacher was a big Pink Floyd Fan. He arranged a day out for the whole class to go to London for a Demo Of the New Quadraphonic sound, as It featured a first play of the Pink Floyd's Brand New album called, Dark Side Of The Moon. I was really taken aback as to How Clear the sound was and Immersive It was. As soon as the Weekend came I raced Into the record shop and Ordered one (the Straight Stereo One) with the solid Blue Triangle, and I still have It today and It still looks the same as when I bought It. I never could Afford to buy the Equipment, and when You did find one It was the Wrong Format one to play the Records I now Own (Not bought from New). They where going to put the Universal Quadraphonic Tech Into Receivers when they started to sell heavily. But they never got around to doing this. I would have preferred If they had taken out the Radio side (Never used It) and replaced It with this Tech. Even If they did that for just one Model. Nearly every Home Theater has a Turntable attached to It. Thanks for Sharing.

Our nextdoor neighbour in California in the early '70s had a quad set-up - he invited my Mum and me in to show it off a few times.

Wow great detailed video!

Just started to collect quad tapes and ordered Elvis live from Hawaii on Quadra disc . To me they sound great!

Song of the day Moving in stereo - the cars

Another advantage of playing Quad records on stereo equipement : They are a (kind of) remix of the original album . So you can hear details or parts of instruments that you never heard on the stereo mix (especially with SQ (Columbia/CBS) ) . The best examples i can mention are Santana ''Abraxas'' and Simon & Garfunkel ''Bridge over troubled water'' . And they sound way better with a good pair of headphones !

Hi there! Yes, I have a lot of quad albums on vinyl (mostly SQ and QS) in genres from pop to classical. I enjoy them in full quad sound via the Involve Surround Master, which also makes regular stereo recordings sound great as well. Favorite albums include the movie soundtrack of Funny Girl, Barbra Streisand’s Stoney End, Antiphonal Music for Four Brass Choirs, Bernstein’s Mass, and the Cast Album of Company.

1973's Aloha from Hawaii. The first quadraphonic number one album on the U.S. Billboard chart. Just thought it rated a mention for its historic place in the story

Yes . My dad collected a lot of them as well as CD-4 7” real & some Q8 tape. I collected a lot of the 5.1 DTS CDs & DVD A so I enjoy listening to them in the center of the room. I think it deserves more attention for music lovers , not just home movies. Play on vintage McIntosh W/ Marantz CD4 turntable

I have a quadraphonic pressing of Dark Side of the Moon, it’s awesome

All Things Must Pass by George Harrison was a quad and when they remastered it to CD they also had it in quad but in these days playback is solved with a surround receiver in the Dolby Pro Logic II music setting. You can ‘force’ anything into surround but it won’t have the experience it’s meant to provide if it wasn’t recorded that way.

Thanks for your channel. I'm from Chile. We speak spanish here and I can understand every single word you say! Thanks for that too! Great channel!

One more thing. Many artists made a seperate quad mix so in essence, it's another version of the songs. Santana and Steely Dan just to name a few,as well as Dark Side Of The Moon

Excellent explanation!

J-RAD !!! Wassup brother !!! My Dad always talks about the time him and his buddies got high and listened to Emerson , Lake and Palmer on a quad set up back in the 70's . He said it was so awesome .

Great video,thanks for this,I got one,Santana - Abraxas in SQ format:)

"I won't bore you with the technical details..." That's why I clicked on the video, man. Give the deets!

Excellent video!

I have a Sansui QR-4500 4z-channel receiver that my Grandpa gave me, and later on he gave me a few Quadraphonic records which were: Bridge Over Troubled Waters, Abaraxas, and that compilation you mentioned

Wow, thanks for the rundown on quad technology, Way back when I was in elementary school, My dad and I walked down the street to go visit one of our neighbors, And our neighbor was sitting in his garage with the garage door open, and the neighbor was a long haired hippie looking guy, And he invited us to come inside his garage to us to listen to his quadraphonic disc; It definitely blew my mind with the four speakers, and the music moving around between the four speakers in his garage; Of importance to his setup, he had a joystick that he could use in order to center the particular piece of music; That stuffs was way over my little head at the time; However, I wished very badly that they would eventually come out with stereo television; And they eventually did; Yay 👍

I had a stereo that was a changer with 8-Track and AM/FM in the 80's that I bought for $10 from a resale shop, which had the Quad ability built in. And happened to come across a Joni Mitchell album in Quad, "The Hissing Of Summer Lawns", if I'm remembering the title correctly. (Not sure which system Asylum Records used for it, but sounded frigging awesome!)

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. 🙂

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.👍😎

Yes, I have "Elivs Aloha From Hawaii" in quad. I don't play it since I don't have quad equipment. So I bought the regular stereo version. I'm good with that.

I've got one quadraphonic album by Milton Nascimento. It's a very famous singer in Brazil (and many people outside Brazil know him). It uses SQ technology, but I've never heard it with quad equipment. I've only listened to it on stereo record player and it sounds great!

*Song of the day:* "Otso Otso" by Bayani Agbayani

The answer to the QS, SQ, CD-4 , etc. , question was four track-four channel reel-to-reel tape.Yes they were available, usually via special order.

Song of the Day: Mammagamma by Alan Parsons Project (1982 Arista AL9599)

Have yet to hear quad. Finally broke down and ordered what I need for SQ as well as Darkside of the Moon pressed in SQ. I know I do have a few others. 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.

Is there a way to adjust a tone arm without an adjuster? Mine doesn’t have one 😕

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

Company is actually the best broadway recording ever created. It's so good! There is even a documentary on how it got recorded. I can HIGHLY recommend it!

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.

Been wanting to get an SQ decoder for some time, but I was wondering if that also required me to get a 4-channel reciever as well. Anyone know? It's hard to find good info about these things.

i have a question: how do sounds play from speaker to speaker on a record? it’s just grooves. what i mean is when a singer is switching the singing from the left earphone to right to make it sound like they’re in your head, but how would that work on vinyl

Hey Jared, how do your Bohren records play? Are they quiet? Do they sound good? Thinking about picking them up.

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"-!!

Good Video !

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..

Hi, A little help here. I'm considering a couple of turntable, the Fluance RT80, the Audio Technica LP3BK and the AT LP120XUSB? Which is better? Thanks!

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.

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

Is the front LR output different on a matrix quad album if you play it in quad vs in stereo?

Techmoan is a great KZfaqr. He always finds very interesting and unique tech that is very fascinating. One of my favorite KZfaqrs.

7:43 What stylus are you using there? I looked in the description and it said 2m red but thats definitely not a stylus that I've seen before!

I read in a 1974 consumer guide book on audio equipment that if you played one type of matrix disc with another type of matrix decoder, for example an SQ disk with a QS decoder,

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.

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

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.

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?

Hey, Vynil Eyezz, if you haven't already, have you ever thought about uploading a compilation of bloopers? e.g., instances where you got tongue-tied, misspoke, dropped a record (heaven forbid!), etc. That would make for a great video!

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.

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

Hey! I just stumbled on your channel and have been watching a ton of your stuff for beginners. I have an Audio technica lp60x player. Anytime I play a record the music plays from the vinyl itself. It sounds awful and kinda stops me from playing my vinyl :/ Am I doing something wrong or is the player defective? Love from Austin!

Nice video. I started to built up my gear for quad, it includes: CD-4 demodulator (JVC) including the Shibata nude stylus, SQ decoder (Sony) and a QS decoder which includes the option for SQ decodification (Sansui). I also have the Susane Ciani vinyl box. The problem I am facing is to have a good quad amplifier (vintage) I purchased a JVC 4VN-990 which unfortunately have two channels weakened, it is in the technical service now and I hope it will do a good repair. I am very enthusiastic about quad sound I do hope I will have my whole system fully working soon. If anybody has a good suggestion for a quad amp it would be very appreciated. CHEERS!

I have a quad system. It's 2x Sony TA-1150s linked with an SQD-2020. I have 4 Wharfedale Diamond 10.2s and a Sony PS P7X "Precise" turntable. All the base equipment was made for 4 channel sound, with the manuals boasting about, "The sound of the future, today!" Actually you can get quad sound out of KZfaq with the old decoders, since the information is still matrixed into the two channels. I've had good success with Enoch Light, Morton Subotnick, Electric Light Orchestra and others. I have a few SQ and QS vinyls, including Japanese promotional ones, my decoder does both SQ and QS. I bought the Jackson 5's CD-4 re-release but I can confirm it does nothing special on any of the decoder's settings, because I don't have a turntable with the special stylus on it. Quad's quite a lot of fun, really. It even has a trippy "2-4 channel Ambience mode" which makes Netflix and PlayStation games pop.

Song of the Day: “Free Bird” by Lynyrd Skynyrd

Great video . I own three SQ records .. but never got the chance to listen them on four channel.

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

I was wondering about that exact thing.

The first broadcast from a theatre in London was actually in stereo; it was a direct connection rather than through radio. They had left and right channels.

Hello. Could you please do a video on Direct to disc records. I have a few and they’re very clear as opposed to normal records. Back in the day, Sheffield labs made quite a few in which I have among others.

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.

My record player is hooked up to a 7.1 sound system. I, of course, set the audio signal from the turntable to be all channel stereo on the receiver. Meaning all of the speakers right side play the right channel, and all the left speakers play the left channel. The center channel plays in mono, I think, so I simply adjust the volume on the center channel to be much lower than the rest of the speakers. This setting gives the music much more fulness and body. I feel engulfed by the music. As apposed to using the direct signal, which would only play music on 2 speakers from my 7.1 setup. I wish quadrophonic records would make a comeback now that 5.1 and 7.1 sound systems are more common in households. Vinyl as a whole is becoming more popular these days. Now is the time to bring back quadrophonic records. I have a few 5.1 audio DVDs that sound amazing. Each instrument plays from 1 of the 5 main speakers. The center plays the vocals, front-right plays lead guitars, front-left plays Keyboards, back-right plays vocal harmonies, back-left plays rhythm guitar/ambient sounds, and they all mix in a little of the highs/treble from the percussion/drums. Of course the sub handles the lows from drums and bass guitar. When you close your eyes it sounds like a live band in surrounding you playing just for you. I want this for my vinyl too, so bad!❤❤❤

great info, love the album you recommended "The Long Run" especially the song "evergreen by bootstraps" and Vian Izak Dan Russo "As You heald/the guid"

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.

Did you at least try to use the LP that was Quadrophonic on a home theater amplifier in the pro logic or any of the other settings to see if it in might kick in?

That vinyl moon release is probably my favorite I’ve gotten yet

awesome!

Song of the day: Holy Diver - Dio

Hmmm. since almost a year, i was too lazy and only have one of my mission speakers placed behind me in a shelf connected to my computer. I'm kinda used to it. LOLLLL

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.
