Errors/Updates 1) Moog is pronounced Moog not Moog....as in "This video does not feature the Moog" 2) It appears that the dad in the outro mis-remembered that his 1970s Ford Capri was a 2.8i when the 2.8i model only came out in the 1980s. However after a bit more pressing it turns out that he never had a Capri - he owned a Vauxhall Viva, he just said he had a Capri to sound cool.

Quadraphonic? Awesome! I’m listening to the video with a single earbud...

The Quadraphonic mix of Dark Side Of The Moon was phenomenal, also the only actual quad record I ever had. If you can find a copy, I highly recommend.

Techmoan's willingness to get outside his usual musical comfort zone for the sake of a new format experience is honestly the most wholesome thing on the net these days.

Quadraphonic sound, a strobe light, and a water bed; gentlemen, say hello to the Second Base Mobile

“An alien landscape of noise.” - I thought you were talking about your shirt for a minute there Matt.

Suzanne Ciani is also known for her work in creating one of the first composed soundtracks for a pinball machine. She did the soundtrack to the Bally game called Xenon. She has a lot of fans in the hobby.

I actually have a Sansui QR-500 quadraphonic amplifier from 1973. Still works like a champ.

"I used to have Quadraphonic sound in my Ford Capri" XD .. Brilliant ending. Thanks Mat!

My aunt and uncle had a quadraphonic stereo and I remember listening to Switched on Bach and it was amazing. Electronic music is what got me interested in computers and here I am today a software engineer. I wish I could bring that experience back.

Never did i expect modular synthesis to make its way to your channel! Great video as always!

'i wouldn't even call it music...' Best review ever 🤣

"I'd probably like another listen to that." I hope they use that as a review quote on their website 😃

You have more shirts than James May!

I hope we see more of these releases as it's a fantastic experience being totally immersed in the music.

I have Pink Floyd Dark Side of The Moon & Deep Purple - Machine Head albums recorded with the SQ Quadraphonic system.

I love the art house shirt Matt, very appropriate. I'm now 63, for a time in the 70's and early 80's I had a business in Hammersmith configuring Quadraphonic listening rooms for people with loads of money and little taste. The problem with Quad was not only the competing formats but also the lack of media. People just got bored with listening to the few quad recordings that were in their particular format. What really made multi field systems worthwhile wasn't music at all but the rise of multi channel video. It always amazed me that you could get a Dolby 5.1 surround system to watch your favourite movie that sounded amazing but the picture was in crappy 720 by 480 on a relatively tiny screen. What was/is kind of sad is that very few music recordings take true advantage of a 5.1 or more system. Most recordings are nothing more than a stereo mix with a bit of field panning.

The first and last time I heard quadraphonic was in 1973, Dark Side of the Moon. I've often thought of searching for a copy of that album and something to play it on. The end was pure gold

I didn't know about this! I'm UK based and own a Buchla 200e (her instrument... well she used a 200 back in the day) . I love Suzanne Ciani, saw her live earlier in the year (first time in the UK)

We had a late 70's ford thunderbird with a quad 8 track, which we always thought was the best thing about the car. Afew albums we really loved ,you might also enjoy. Ike and Tina Turner live at carnegie hall called what you hear is what you get . . . Very exciting excellent recorded performances at the top of their game. The ford quad demo was great too, with a varity of top acts from various genres. Santana had a great album out at the time as well. All were very engaging in the quadrophonic format. Happy hunting and thanks for the shows 😃

Haha, love the ending! You can’t win with your dad! 😂

I remember my uncle gave me a quadraphonic decoder with accompanying stereo/amps/speakers back in the 80s. I set it all up and was rather disappointed not fully understanding what it all was about. The little woodgrain box with a stainless front plate and chrome dials had a several settings including "quad" "matrix" "fake quad" and "cross" I believe. It sat at "fake quad" most of the time just to make all the speakers output sound not knowing any better. One day I noticed a record at a second hand store that said quadraphonic. Out of curiosity I nab it, set the setting on the decoder to "quad" and play the record. I have no idea what the record was now, but I was quite impressed. Then I noticed all the records we already had that had such a quadraphonic label :-). So so long ago, and I was so young.

This was really fascinating! I'm glad you had fun with it. Very interesting but then I like all your videos. Thank you very much!

Dude if quadrophonic vinyl comes back I'm gonna be so happy. Wicked video as always!

oh my god the puppets killed it here. such a hilarious ending!!

I've watched a lot of your videos and I don't think I've ever quite seen you as giddily excited as the beginning of this video

Back in 1975 I saw the movie "Rollerball" at the Cinarama Dome Theater in Hollywood. The movie featuring "Quad Sound" and speakers (Infiniti) were placed in the isles for this propose. The movie was based on an extreme roller derby sport and as the action on screen went around the track, the sound would move between the speakers. I thought this movie might kickstart the Quad sound system but no one followed this formula. We would have to wait for the 5.1 systems in theaters much later. I had a few friends that had Quad systems but they were cheap units and there were only a few LP's available and compared to a quality stereo no one would choose quad. Thanks again for the trip down memory lane.

The album sounds pretty wicked, even in Stereo. I can only imagine what it sounds like with a quadraphonic setup.

just wanted to drop a nice comment and say that I just love your videos! also I rather enjoy the puppet endings!

Loved the end sketch! Thank you for making such great content!

I love this channel so much. Thank you Mat!

Cars should adopt quadraphonic audio because they would be the perfect implementation of the format in my opinion. This would help bolster it’s appeal. With digital audio file formats like caf files being lossless and AAC lossy both able to render quad & stereo mix down files in a single file and decode them properly and instantly weather you are listening in quad or stereo. It is as simple as choosing the option at mixdown (render) in audio workstation software like Apple’s Logic Pro X, quad just seems like an obvious step in the right direction.

Day off work and a techmoan vid! That's my day made!

I've got a bunch of my Dad's old CD4 disks, but no demodulator and no fancy stylus. Quad is so hard to research these days, so I'm real excited about your future video!!

I just picked up Suzanne Ciani's Buchla concerts on vinyl two days ago. To see her mentioned here is really cool.

The main difference between Buchla and Moog synths is one of approach not technology. Don Buchla was more interested in experimental music and his machines were full of odd controllers like capacitance pads. Bob Moog wanted to create an instrument applicable to any kind of music. The Moog had drum and ribbon controllers (think sliding your finger along a violin string) but it was mainly a keyboard instrument.

This is the first time I can recall seeing The Moans (don't know their proper names) segment where the son comes off as the rational one and the dad comes off as the daft one. Still funny either way.

Been waiting for a video on quadrophonic records! Nice!

I loved the "acquiring the taste" montage at 7:41. Nice little touch to the video

I hope your videos renew interest in Quadraphonic sound like they did with cassettes. Bring on the Quad revival!!!!

Hahaha as a Capri owner and enthusiast i had to laugh! We have just done a 50th anniversary car show on Sunday and i bet this conversation came up somewhere!

My first Quad lesson was on a Buchla Model 100, at the University of Washington (mid 70’s). The quiz involved making a ping-pong ball sound and having it move from speaker to speaker. It was expected to get faster and quieter with each bounce. I don’ t now recall if the Model 100 had Buchla’s combination VCA/low-pass filter, which could have reduced the “ball’s” overtones along with it’s volume, as it proceeded around the room. But that’s an example of Don Buchla’s way of looking at sound. (Later models do include that VCA.). To hear a Model 100, check out Morton Subotnick’s “Silver Apples of the Moon” (the first modular-synthesizer record). Also, check out “Lost Voices of Hagia Sophia” by Cappella Romana, on Blue Ray, for a 5.1 representation of the great cathedral of Constantinople (aka Istanbul). Now, if the 5.1 “center” speaker were overhead and the four corners were balanced for quad ... hmm.

Keep up the amazing work and love your sense of humor. I am a big fan of yours!

Hi I built my own SQ/QS decoder from the circuit diagrams published in Practical Wireless magazine here in the uk ( Oct 73 - Jan 74 ) . I purchased 2 records to play on the system from the US as no shop in Oxford had any at the time . Tubular Bells - Mike Oldfield ( SQ ) and Music - Carole King ( QS ) . I killed my decoder after moving house ( Wrong Power Supply ! ) and have never got around to re-building it . I have not tried playing the records through my Pioneer VSX-D810S , infact I have not played a record for years . I don't expect that my turntable still works ! Thanks Alan

Loved this! I believe Mike Oldfields first three albums were released on quad vinyl in a box set called 'boxed'...would be interesting to hear this played through your quad set-up.

Okay, that ending skit was actually pretty funny. Informative and entertaining as always, Techmoan.

Awesome. So many examples of technology for audio that was never embraced by the masses that was so superior and advanced.

You need to get a quadraphonic copy of Dark Side of the Moon.

My neighbour had a quadraphonic system in the 70s. He demonstrated it with the sound of a motorbike racing round and round the room. Was it John Lennon who said stereo was for boring people who only had two ears?

Grew up with a quad system. Dual quad record changer and fisher quadraphonic reciever. Four wood tower speakers and a whole lot of quality music.

We have seen the 50's diner setup in context with the rest of the room. THE 4TH WALL HAS BEEN BROKEN, THE ILLUSION IS SHATTERED! Also that rip at the end regarding the puppets. Nice! Ah, I should look up that woman - judging from the samples you provided in listening that album and her work may well be something I'd enjoy. I'd imagine in quad it would be quite the experience, the fact its from vinyl being an added bonus. Great video Mat, as always. :D

Maybe I'm just sleep deprived... But the sketch at the end had me on the floor. Well played.

Yes, the old Version of Cuba Baion as the background music for the muppets ❤️

Man, I enjoy every single one of your videos!

I'm continuously amazed at what you find; thanks for sharing!

Nice to see the quad decoder redone in a modern DSP :)

Regarding the Kanto vs Roth speakers sounding the same - I know Kanto is a Canadian company, they're in Coquitlam (part of the greater Vancouver area) and their stuff is designed there. I bought a Sub8 a few years back and was surprised at how fast it shipped to me in Edmonton - it came rail freight direct from Vancouver and shipping was basically free. Roth's other products don't resemble Kanto's enough to just be rebranded Kanto stuff. It was weird when they started actually selling Kanto in great quantities here in Edmonton, I can go out and buy GOOD powered speakers at like five different stores around town instead of being offered the usual Best Buy dreck (Bose/Klipsch/Sony).

That moment when you're off work for a week and you think sod it I'll get up early and make the most of the day. You get a brew ,some toast, and pop open the laptop to see that Techmoan's uploaded another video... A fantastic start to the day in my opinion.

CyKiK, Thank you for the explanation... AND making the audio files available! Being a geek, getting a board and hooking up a bunch of speakers is right up my alley. But, space... Using a predefined encoder already in my surround system is much more 'practical' I'll be trying the DTS Neo:6 and Dolby Prologic decoders. . I get your comments about mixing engineers getting their head around mixing in discrete channels before going to an encoding format. When I dabbled in 5.1 mixing, I did 6 discrete channels and mixed to encoder. It was always a trial-&-error to get a final mixdown that sounded close to the original. I have been impressed with the limited new audio I have been hearing. It really seems like the modern mixing artists are doing things well. . What a great project!

Thanks for the video Mat. I'm not a purist audiophile. Your setup worked great for you and that's what counts. My friend Paul has a 1970's quad vinyl setup and he demonstrated it once with the famous Pink Floyd LP Dark Side Of The Moon. The record jacket had an explanation of how SQ worked. I guess there are photos of it on the internet or I can ask Paul if he can photogtaph them for you. Best wishes.

I had an 80s quadrophonic amplifier it was high quality I wish I kept it now..also I wish I kept my commodore 64.

Fascinating stuff. Ciani performed at the BBC Proms this year at the Albert Hall. Prom 13 on 23 July was called "Pioneers of Sound" and featured pieces by Daphne Oram and Delia Derbyshire. Ciani played "Improvisation on Four Sequences" live, from a small platform in the middle of the floor of the hall, so presumably the sound came from all around. The BBC HD transmission on BBC 4 was in 5.1, but I don't have a decoder. Might have to upgrade my system. It was quite impressive even in stereo. The effect in the hall must have been stunning. Looks like she used the same setup as the live concert you linked to. Back in the 70s, my dad, who was a classical musician, had a Rotel tuner/amp with Quadrophonic capability. I can't remember which system it used, but playing quad LPs was impressive. He had a number of Deutsche Gramphon that I remember but I have no idea where it all went. Last time I saw the Rotel it no longer worked.

Thanks for all the tech, both old and new. But I still think your sense of humor shown through the puppets is your best feature .

I remember reading that the shibata stylus was created for quadrophonic records as regular styli couldn’t pick up enough detail in the higher frequencies where the rear channel information was encoded. So, you might have even more luck with your Denon T/T if that uses a shibata. Also, if your AV amplifier has analogue inputs, you should be able to get a quad system running through your existing surround setup. You probably already know all of this given the amount of research you usually do for your videos, but I thought I’d mention, just in case :)

You really should just integrate quadraphonic to your current 5.1 setup. If you have an analog 5.1 input on your Marantz, plug in your CD-4 demodulator or QS/SQ decoder and ignore the center and sub inputs.

WoW! I remember going to the local Ford dealer in my home town and got told by the guy behind the counter that I would never be able to hook up my new tape deck in my dad’s car with two Ford stock wire harnesses. Privately I got mad at him, said ‘screw’ him, and I made my own custom harness and hooked it in parallel with the station wagon’s stock radio system, since this is the first car I had ever seen with two speakers in the front doors and two speaker in the bottom section of the rear tailgate, and a front to rear balance control on the radio. What did I successfully hook-up and enjoy immensely until my dad had to get rid of the car for another? A Pioneer 4-Channel Discrete 8-Track!!! Yes, Indeed!! This was the only way at the time you could get into totally discrete quadraphonic music without spending the big cash for a Teac 4 channel Reel-to-Reel tape deck (I had one of those too because of church music recording. That particular reel-to-reel was originally designed for synchronizing and over-dubbing with different music instruments via sequential recording, but easy adapted to quadraphonic prerecorded reel-to-reel music which was definitely being produced at the time.) I still have quadraphonic LP records I had purchased thinking I was going to commit fully to Quad indoor components. But never did. Unfortunately quadraphonic was an economic failure. But the 4 channel idea did carry over into Dolby Pro Logic as encoded movies were the proposed next level of surround. I remember having one particular prerecorded quad 8 track which was wonderfully produced, by the Moody Blues. On one particular song key musical instruments would scan-pan around to all the 4 channels while some instruments would stay totally in the front speaker pair, and other instruments in the rear stereo pair. Completely unrealistic to a live performance, but unusually fun and exciting to experience; especially in the acoustically optimized environment of an enclosed car. Ahhhh!! The good old days.!! I never committed to buy an indoors full Quadraphonic receiver with all the built-in decoders; it was just too doggone expensive, and you could buy a much better normal HiFi stereo system for the same amount of money. A fairly recent few years ago I saw this guy somewhere on the internet who was converting old Quad LPs to more modern Dolby surround systems found in more recent HiFi receivers as an outsourced service to potential customers. I though this was very cool 😎, but have never had the interest to try it. This is definitely something Mr TechMoan might find interesting to experiment with. And ‘Yes’, I do remember the QS quad system that Sansui had in their quad HiFi units, and those beautiful receivers, some of which had 4 VU meters for each of the audio channels. Since I never had the hardware to play back the Quad vinyl LPs, was it actually worth it in terms of the sonic experience?? Somebody out there knows, for sure. And there was more than one Quad LP decoding system. And as I recall QS, TechMoan is showing us with his decoder, was not the most popular. Am I remembering correctly that the SQ system had more LP records available?? Also for those who are interested, or who still have functioning equipment, add your valuable comments here. Pioneer, Akai, and a few others had equipment manufactured to support different quadraphonic decoding schemes. Sure..I’d like to see the some form of quad return. But don’t I remember seeing kinda of, what we’d call Quazi-Quad music recorded on some kind of much better modern decoder system? Comments welcome to expand this discussion.

Very interesting video. Thank you Mat!

We had quadraphonic FM radio stations in Houston, Texas back in the early 70s.

I think they would have a much better chance to revive quadraphonic if they recorded a live studio performance with many instruments. Electronic music from a box is more like.. standing in a discotheque.

ahh, I love me some good glitch music. Thank you for referencing the artist. I will have a listen. Awesome video.

Please, never stop making the outro skits. They're perfect!

Looking forward to your view of the Toshiba SB-404S, I've had and used one for years (been in storage now for the same amount of years or so). Bought it for the four blue VU meters :D And I've bought every quad vinyl I've come across. And indeed: a Dolby prologic/digital decoder also gives quite an approximation.

Suzanne was at the BBC Proms this year, if you watched it on BBC4HD it was broadcast in Dolby Digital. She sounded amazing too 😀 sounds were flying all round my living room, was a great experience 😁 Denon receiver and 5 Mission speakers and sub btw 😉 Great video as always ❤️

What a coincidence. I was watching this channel last night and I’ve just set up quad in my house this week. Not because I like it. I just have two old hifi amps and four speakers and wanted surround.

A Techmoan video about Quadraphonic sound? God I love this channel.

Thank you so much for reviewing and giving insight into this stellar quad vinyl release! I've mixed and released 4 albums now in quad (digital formats) and it's great to see more and more people getting into quad and multichannel music! For more on Symbion Project and Kodomo quad digital releases, visit here: quadaudio.bandcamp.com/

I went to a live quadraphonic performance of Suzanne Ciani, she's very funny. It was a double bill with Midori Takada.

I have a few Mike Oldfield Quad Vinyl Records, but only ever heard them in Quad once - amazing - nice to see any form of vinyl make a come back, loved the video, always interesting :)

Amazing that you finally crossed over into the synth world w/ Suzanne Ciani! Now you'll start looking into Eurorack and Buchla Synthesizers!

$227 each..wow is was expecting $500+

In Soviet Russia the four corners listen to you!

I remember having read an article in "Stereo Review" back in the early-to-mid 1970s about how you could get a reasonable facsimile of Quadrophonic decoding by simply adding a 3rd (rear) speaker whose leads you connected to the "hot" speaker outputs of the L and R speaker outputs on your two-channel amplifier. The idea is that the third (rear) speaker -- which you would place behind you -- played the "difference" signal between the two stereo channels. I tried it out, and the results were astonishingly good. The first vinyl record I tried it with was the eponymous "Emerson, Lake, and Palmer" album. In the final track, "Lucky Man," there's a great monosynth solo at the end of the track, and heard through this three speaker arrangement the synth sound seems to arch up over your head and go behind you. Whew! You may want to try this sometime. Even with a cheap 3rd speaker it's amazing.

Great! I love your channel. Unique and wonderfully done!

I bought this album on iTunes for $5.00 played it thought my Denon DSP and it played in Quad. Saved $222.00

7:46 - Me in my bed at night

I've had a turntable and preamp hooked up to my Onkyo 5.1 for the last 12+ years. The Pro-Logic in the receiver decodes QS vinyl with incredible clarity and precision. This is the way I originally head 'Bitches Brew', off the quad vinyl. For a time (over 2 decades), there was a lot of QS/SQ vinyl clogging Goodwill stores.

It’s really awesome to be able to see a quadrophonic record in 2018! I’ve always wanted to hear what one sounded like and it was quite interesting to hear that on the video

7:41 "Oh my God, why am I doing this"

I shall not sleep until I can get octophonic sound from a cylinder phonograph.

Great to see the boys back.......Great video too!!

Possibly the best outro yet! Did make me chuckle!

"The Dark Side of the Moan" experience ? ; ) ...now to go find some Morton Subotnick

Silly puppet. You wouldn't get the drums in a Capri through the doors. You'd lift the tailgate! ;)

Your house is slowly turning into a (hifi) Museum. I love it!

The puppet sketch at the end mimics every conversation I have with my 83 year old father! Hilarious 😂

If my memory is correct, there were two flavors of quadraphonic: Discrete and matrix. Discrete is true four channels, from four different audio tracks of whatever you are playing. Matrix is a bit artificial. It takes two channels, and through some circuitry, outputs four channels, but it's not true discrete sound. I'm unsure of how four channels of audio would even fit in a vinyl record groove, especially since you used your own record player that could only do two channels. I'm guessing this was matrix coming from your speakers. The decoder you got should have been sold with an enclosure around it, instead of a loose circuit board. That would make more sense, as most all audio components are enclosed in something. We usually don't tear off the enclosures around a radio, computer, microwave oven, etc., before using them.

2:19 The double space between “Dear” and “Mat from Techmoan’ smells like a form letter to me.

In the 70's my dad had a Sansui Quad reciever,with built in 250w per channel preamp. Our local radio station WDIZ/100.3 in Orlando,Fl. broadcast in quad back then. It was awesome!! Pink Floyd,Mike Oldfield,Jethro Tull,Deep Purple,Rush,and many others were often Rocked out at highest possible volume when ever my folks weren't home and my friends came over.
