In case you haven’t realized it by now,
this channel is called Technology Connections because I’ve always been fascinated by the
way innovation happens. When we think up new things, we’re often just making a connection between a number of concepts and using those connections to achieve new goals. I also enjoy exploring the connections we humans have to technology itself such as how we interact
with it and the way it changes our lives, or sometimes… doesn’t, despite monumental efforts. And today I have a device which fits neatly into both of these categories. And it’s… not this. You’ve seen the
thumbnail and title. I know you know that, but first we must make a Technology Connection. The Compact Disc was a truly revolutionary product in a number of ways. First, it spins. Second, it brought digital sound technology to the masses. And third, it wound up being
the first truly successful optical disc format, unequivocally proving the merit of the technology
through finding applications in everything from sound, to video, to software. Sorry, Laserdisc, but being first isn’t always best. Compact discs were a radical departure from
the conventional audio storage technologies we had at the time. In 1981 you had your conventional
vinyl discs, known as phonograph records -- Please. Never. Call this. "A Vinyl," you heathens. It is a vinyl record -- as well as your tape formats, mainly the compact cassette but if you wanted to get reel fancy maybe you’ll have a reel-to-reel deck, too. Or perhaps you’re clinging onto
your 8-tracks like some sort of 8-track clinger. But in 1982 (more practically 1983) Sony and Philips released the fruit of their teamwork, the Compact Disc. See, it’s a disc, but smaller! And shinier. Using a laser, a photodiode, some focusy and tracky bits, a spoonful of signal analysis, a few quarts of quantization, some exciting error correction algorithms, a dash of data parsing and finally a delightful digital to analog converter (DAC), you’ll experience sound like never before. I made a bunch of videos about the compact disc
which you can check out in that playlist. As time wore on and we got better at making
the mechanisms which read the disc, we found we could make them more compact. Of course Sony had their famous Discman compact compact disc players, and so did everybody else, but along with smaller transports came ways to automate the changing of discs. In the late ‘80s CD changers started to appear on the market, many using magazines, with a particular
niche establishing itself in the automotive world. The idea of setting up a sequence of discs
to play one after another wasn’t new at all, in fact for decades record changers were a thing. I also made a video about those! They were responsible for the record sets you might have come across which have their sides in a seemingly weird order. In fact, that order makes perfect sense
for stacking changers. So, naturally, as CDs became more popular, CD changers became desirable. And the alternative to a magazine-based CD
changer was the soon-to-be-popular carousel changer. With these, you can load up to five discs (usually) to be played one after another or even randomly, and some like this one even allow you to load new discs as the one it’s playing is playing. These work by placing
the actual CD transport deep within the machine, and a specialized disc tray holds the discs
on a motorized turntable. To change discs, the player simply releases the disc it’s
playing and spins the turntable to move a new one into position. Then one day, somebody at Fisher thought to
themselves… "Turntable! Tuuuurntable. Record players have those. What if…" and then this happened. This is a Fisher DAC-145, a very clever if a bit silly device. A combination
5 disc CD changer and standard phonograph. It seems to have been released in 1990, though
I have found a reference to it as far back as 1988. It was also available as a component
of the 9025 system; you might therefore find this device existing as a DAC-9025, but it’s the same thing. Now, Fisher Electronics began life as an American
company manufacturing audio equipment. Founded by amateur violinist-turned philanthropist
Avery Fisher in 1945, they specialized in hi-fi gear and were pretty significant in their early years. Among their accomplishments were the first solid state hi-fi receiver and also the precursor to the component systems this very product was a part of, introducing combination turntables and radio receivers. Their early products used the tradename “The
Fisher” but at some point they dropped the The. Fisher the person sold the company to
Emerson Electric in 1969, and apparently distributed a lot of the proceeds to his employees. Cool dude. Then in 1977, Emerson got bored with it and
sold Fisher to Sanyo and from that point on, Fisher was a brand of Sanyo. At least until
Panasonic then bought Sanyo, and now it seems they can’t be bothered with the brand. Anyway, that means that really, this thing was made by Sanyo, and though I have admittedly not
looked super deeply, I can’t seem to find an equivalent Sanyo model so it looks like it was produced for the US-market only under the Fisher brand. Underneath the dust cover you will find… a very bizarre looking layout. You have what is clearly a tone-arm to the right, and what looks to be another superlatively girthy tone-arm to the left. The turntable looks like nothing
that could possibly belong in a record player, though. It’s full of holes, and a bit bigger
than it needs to be. But, no doubt about it, that’s a turntable! It’s got a silver spindle in the center, and we even have a space for your all-important 45 RPM adapter. You will find two buttons up here, a speed
select button toggling between 33 and 45 ripms, and a mode selector button which toggles between
the oh-so-fancily spelt analogue (very chic, very European) and CD. The power is on now,
and if I unclip the tone-arm from its resting place, there goes the turntable. If I put a record on it, you can see that the record doesn’t quite go to the edges. And you might
also notice another glaring problem that we’ll get back to. Every time you turn it on, it powers up in
record playing mode, ready to play a record. In this mode, the player’s display simply
shows the word “uh-NAH-lo-guay” to the right of a teeny tiny record player icon (it took me longer than I care to admit to realize that that wasn’t just a stylized numeral 1) and of course it also indicates which speed it will spin at. Because this thing is in fact a functional
phonograph. It even features automatic tone-arm return. How fancy. But of course, there’s
a lot more going on here. There are five spots for compact discs to go, complete with handy dandy labels. Now if you know a thing or two about compact discs, you’ll know that we should find a laser pickup mechanism of some sort under one of those cutouts. However, it appears we don’t. I can spin this by hand quite easily, and nowhere do we find a laser’s objective lens to cavalierly touch. Ah but hit that mode switch to switch into
CD mode (annoyingly spelled in boring US english) and watch what happens. Nothing. OK but instead
let’s put a disc in the disc 1 position and now select disc 1 on the front panel and
hit play. Now the turntable moves but in a slower and more deliberate fashion, and brings disc one near to the girthy tone-arm. Once it stops, that tone arm slides over the disc
automatically, and as it does so we can see a little shutter move from under the disc, to the adjacent space. That exposes the transport hiding beneath, and the CD gets lifted up into the arm’s embrace. It starts spinning, and now witness the miracle of the Compact Disc. See, that tone arm wasn’t really a tone
arm. You probably knew that, but I appreciate the symmetry of the design here. The way these… shoulders I guess flank the disc tray table is a nice visual touch. In reality the left arm contains the upper half of the CD transport’s disc clamp. See, aside from transports like
these where you snap the disc onto the spindle, in general an optical disc transport will
have a motorized spindle below the disc which spins it, and a receiving dead spindle above it
which the disc gets sandwiched between. That helps ensure it’s centered correctly and
can spin easily. And this is no exception. Most if not all
tray-loading drives work this way. But unlike a conventional disc changer which has a fixed
disc clamp and a spindle which moves up and down to grab hold of or release the disc, this machine moves both the spindle and the receiving clamp. This allows the entire CD mechanism to be completely out of the way for playing a record. The disc tray table
can therefore be a literal turntable, and all it takes to make that play a record is
a tone-arm and a phonograph cartridge. Oh but not so fast, already we have a bit
of weirdness to explain. Every other carousel changer out there doesn’t need to bother with moving the carousel at all gracefully. It can be a sloppy ol’ plastic gear train
with a terrible motor and horrible bearings, and so long as it can move well nothing else really matters. But if you plan to use the carousel as a phonograph turntable too, that ain’t gonna cut it. You need it to move very smoothly so you don’t get flutter from the record. And so, this is in fact made like a proper
turntable. You can actually remove the disc tray, or, I guess, platter simply by pulling up on it and you'll reveal that it’s driven
by a belt much like many record players out there. They even provide a rear access hole
to help with changing the belt. And this makes it even more intriguing. See, every other
record player just needs to spin the turntable at two maybe three speeds .
But this one can’t just spin it, it also needs fine control to turn it slowly and stop
it correctly for the CD mechanism. Which of course means that the device needs some way
to know the absolute position of the turntable as well. That’s done through these index markings which ride between an LED and photodiode beneath the platter. Each disc position has a unique
pattern, allowing it to know in as little as one fifth of a rotation exactly where it
is, and I suspect it also uses these markings as feedback for the speed of the platter when
playing a record. It’s actually quite a shame that Sanyo chose not to support 16 ⅔ RPM records as it seems totally possible given the wide range of control it has over turntable speed and position. And yes, it does in fact use the turntable motor and belt drive to
turn the tray table in CD mode. If you noticed these gears near the center, those are simply for returning the tone arm. There's a bit of an odd quirk, though. You might have caught that something engaged when it switched into CD mode. Listen carefully. [clunk occurs right before tray starts to move] And you’ll also notice that rather than spinning freely, there’s a click now as each CD position passes the reader. That definitely wasn’t there when it was playing a record. This was puzzling to me until I tried engaging CD mode with the plattertray removed. This little nubbin thing moves outward, that’s what we hear being engaged, and you’ll find that it rides against this ridge which has an indentation at each position, causing that click. I’m not entirely sure what the purpose of
this is exactly. It may be simply to provide mechanical alignment with the tray table to ensure it stops in the full upright position, but if that’s its task it doesn’t do a great
job of it. You’ll see that as the CD reader lifts up it nudges the platter tray a bit, so clearly it didn’t stop exactly where it should have. My other leading theory is
simply that it needs to add some resistance in order to be able to stop it precisely. With the belt removed you can see that, thanks to a decent bearing design, the disc platter spins with very little resistance as any decent turntable should, and perhaps that’s just too
loosey-goosey for the precision world of Compact Disc. Oh, and I’m sure many of you want to know
this; Can you leave CDs in place and play a record? Why, of course you can! Records sit quite
a bit higher than the CDs so you can leave as many CDs on there as you like and still
listen to your vinyl. See, that’s an appropriate use of the term "vinyl", you can have a collection of vinyl, but individual discs are not vinyls, GOT IT? Anyway, I must say that the sight of five CDs going for a spin at 45 RPM is mighty hilarious. You might also wonder what happens when you
try to play one of those CDs while a record is still on the turntable. Well, because the record
sits so much higher, as the CD player arm attempts to move into position, it slams right
into its edge and can’t move. After realizing the mechanism never made it to its final destination in time, it reverses the direction, gives up, and switches back to analogue mode. No harm no foul. Oh, and, by the way you don’t have to press the mode selector button to
switch it into CD mode. It will do that whenever you select a disc with the front panel, so it’s not like if you leave some CDs up there you’ll have to open the dust cover every time you turn it on. And, well, it will also switch back to analog mode whenever you move the tone arm out of its park position so in fact that button up there is completely redundant. I must admit this device is quite clever,
and a delight to behold. I mean, ten-year-old me would be thrilled to see a CD spinning in the air like that. That’s objectively cool on its own. So much so that Fisher sold
variants of this model which couldn't play records and were instead just unique CD changers. That probably explains these gear teeth under here that don’t engage with anything at all on this model. On those other models, including the DAC-143 and its component system brother the DAC-9115, there's probably a gear engaged with those teeth to spin the tray. Interestingly,
those models place the upper clamp in a fixed position and move the CD mechanism to the
center-rear. Sadly they made the clamp much larger, so I’m not sure how much of the disc is actually visible while it's playing, if any. But notice that the clamp extends
over the center of the disc tray, likely to hide that center spindle which I suspect is
*absolutely* still there and that it’s the same exact part, minus the rubber feet which grip the record. Which, appropriately, leads us neatly into
the discussion about this device’s merit. Just because an idea is clever or cool doesn’t
mean it’s useful or even good. As a CD player, this is perfectly fine. It has all the features
of any other 5 disc changer, including the ability to change discs while another is playing because… well they’re all right there. Just... just grab one and swap it out. As far as sound quality, well you’ve only
got standard RCA jacks for output so you’re stuck with its internal DAC, but honestly aside from
hardcore audiophiles that’s not gonna bother anyone. Your average person with a HiFi is
gonna hook their CD player up this way, doesn’t even know what TOSLINK is, and will be perfectly
dazzled by this marketing babble. I mean, who wouldn’t want an 18-bit 8 times oversampling digital filter and dual 16-bit linear high speed D/A converters? As a record player, though… ehh it’s not fantastic. So, first; grip. That's the problem I referenced a long time ago when you saw this. There is hardly any contact between the turntable and the record. It’s just these five little
feet, and this rather small center puck thing which, by the way, is itself not solidly attached
to the turntable. Pretty much any record is gonna slip when the turntable starts and stops, and some like this picture disc do so an almost alarming amount. Now, in fairness,
that’s generally not harmful to a record as the sound is in the grooves not on them,
but it means that the record itself is pretty much the only thing providing noise and flutter
isolating mass. Even if it had a really nice grip, the turnplatter is itself very light, and the entire device is, too. This is not prosumer gear by any
stretch of the imagination. It’s cheap. But, as many of you may know, I don’t get
along all that well with audiophiles because I say things like this; it sounds fine, though. Yep, I have but one complaint, honestly, about its sound -
the cartridge is a little tinny and could use better bass response. But I don’t hear any flutter, the speed is correct,
and clarity is perfectly fine. I wouldn’t mind this being my only way to play a record. Go ahead and revoke my audiophile card, I didn’t want it anyway. Want a sample? Well, thanks to Anders Enger
Jensen we have one right here; [electronic music fades in; Discovision]
"Now I'd like to show you some of the valuable things your MCA Discovision system lets you do" "Most persons find it more convenient" "Gently pull up as you press down on the center cap with your thumb" "You'll hear a click" [instrumental portion] Here it is loaded up with 5 CDs, too. "h-h-h-how 'bout that, pretty easy isn't it?" [another instrumental section] "D- D- D- D- Discovision!" "This red light comes on, simply press STOP" And now just with two CDs on one side. "After I've stopped the action, you're going to practice using these buttons" "The Discovision player gives you many special capabilities" "Stop Play Slow; forward and reverse" "Imagine a dog chasing a rabbit around a tree" "How can you get there in a hurry?" [instrumentals resume, then speed suddenly changes] Oh right, that. Ahh, this unit is a bit faulty
in a couple of ways. One is that the switch which activates the turntable when you move the tone arm is a little messed up, and rather frequently it thinks you’ve put it back for a brief moment leading to…
[music fades in, then slips drastically] that. The other thing is that in CD mode it rather frequently
gets stuck in this loop where it stops at the correct disc, but then decides it should
go for another spin. It can do this up to a dozen times before it finally decides to engage the transport. Luckily, once it’s done that, it doesn’t have a problem going from disc to disc as it leaves the upper clamp in position. But anyway, back to the real problem with
this thing. Who is this for? What problem does this solve? Consider that by 1990, conventional
vinyl records were pretty close to over. Yes, they never went away and have seen quite a resurgence in the last decade and a half, but there was a time when they weren’t fashionable at
all and the early nineties through to the early aughts was that time. It was compact
disc for the home, maaaaybe cassettes for the car, and vinyl for your grandparents. If you had a collection of vinyl already, well then
you almost certainly already had a turntable! So, when it came time to get with it and buy
a totally rad CD player, you didn’t need another turntable so this device has no appeal to you. There’s a small potential argument for space savings, but it’s not like a CD changer was a mandatory item. Yes, they were quite popular, and I’d imagine for
a time they represented the majority of HiFi component sales, but if you were sensitive
to space requirements you would probably forgo that option and get a smaller single-disc player. Heck, you could even get a Discman and save even more space, plus get a portable player, too. Also, this thing is not small by any stretch - tons of much better turntables are nowhere near this big. And finally, if you’re buying a component system, space
is clearly not a huge problem for you anyway. But it is… very neat. And I suspect that
made for a meaningful point of differentiation for shoppers looking at entirely new HiFi
systems. If you’re building a system from the ground-up, then this device is quite logical in addition to dazzling. I do however wonder how many people looking for a new system in 1990 even cared about being able to play records. One of the many reasons I wish I had a time
machine. But I can say that from personal experience, records were not a thing in my childhood. The first time I ever played one was in middle school, and me and this device
are in the same ballpark of age. Regardless, although I suspect the venn diagram
overlap between new system shoppers, five-disc CD changer seekers, and people who still wanted to play records in 1990 was pretty small, to people in that niche it’s an excellent
option, though with a compromised turntable (not that my ears are good enough to care). However, I must add here that I think Fisher really missed the mark by not including a pre-amp for the record cartridge. It has two separate outputs for the CD player and the
phonograph, and because there’s no preamp you need an amplifier with a dedicated phono
input. Of course, the component system this belonged to had one, and they were common
at the time, but I still think it was a miss. It forces you to change the amplifier’s
input when you switch between modes when that could have been solved in the device itself. On a holistic level though, this device is
clearly one of those things that, while it could be done, didn’t need to be done. It doesn’t really solve a problem and while I’m sure it’s not like the R&D costs to build it were tremendous, I do wonder if Fishyo took a loss on it. The CD transport mechanism
in this model is unique to it, as it uses a single motor and gear train to move the
arm, shutter, nubbin thing, and transport up and down. I know because I had to deal with
its belt that had gone to goo. Maybe that’s easier to design and manufacture than I imagine, but my business sense tells me that the ROI on this was was probably pretty weak. And the derivative models that shared this design but
couldn’t also play records were… bad CD changers. Again, novel, but who wants to need
to access it from the top? This model gets away with it because that’s just how
record players do but forcing that design onto a CD-only player... is dumb. The entire reason VCRs went from top-loading to front loading was because people like to put
things on top of other things. And so, in a HiFi, the record player usually ends up
on the top. With this design, you really couldn’t also have a record player unless you had a wide-enough space to put them side by side. Or you, just for fun, had a tray-loading record
player and this top-loading CD player. Which, let’s be honest, is totally something I
would do. But anyway, again, I find myself back to saying
that while this is a Certifiably Neat HiFi Gadget, it fails to actually solve a problem in a meaningful way.
That meant that of course it had a small target market. It’s mainly just flashy. And while
Fishyo definitely made a good call by adapting the core design into multiple models to spread
the development costs out, those models themselves required their buyers to value flashy design
more than they do practical considerations. This is a very frustrating device to me. Upon first glance you think, “oh wow, what a neat idea!” and on second glance you see
it in action and go “Woah, that’s so cool!” (when it works) But when you start to look at it objectively,
it makes less and less sense. I would totally love to get it working properly and use it
in my main HiFi system because who wouldn’t want to see this whenever you play a CD, but
I don’t like the record player’s cartridge (though I suppose that could be changed) and
I also just don’t particularly care for its design otherwise. It’s... it's too busy, visually,
and I really cannot stand the layout of these transport buttons. Like, at all. I hate how small stop is, and that it’s between track forward and back. Ugh, it’s just so bad. I’m also not a huge fan of its display. This is certainly 100% personal preference territory, but while I of course love the fact that it’s
a vacuum fluorescent display (and am happy it’s clear and bright on this example) I
don’t really like how it’s laid out. Track time elapsed is really small, though I appreciate
that you can change it to time remaining among other settings with the display button. Though,
I really don’t like how the default state insists on leaving the word "each" floating
over there. And while I commend Fisher for bothering to put an index display next to
it, I actually think it makes the design too busy and they should have just left it out. The
index, for those unaware, is a subdivision of a track which was extremely rarely used
in CDs so this will read "01" essentially forever, and therefore I think it would be better to just... make it go away. Or at least, they should have had the time display the same size as the disc and track indicator. Ehhh.. I just don’t like it. But am I getting rid of this? No! It’s just way too cool. I mean, I love the idea of combining devices like this and think that it's done in an extremely clever way here. One day I will fix that switch and will get this going in a secondary HiFi system or something because it is certainly a treat to use, despite my qualms with it. But I’m also not afraid
to say that on the whole this wasn’t the best idea out there. I’m glad it exists,
and that I get to share this fun novelty with you, but it’s easy to see why this didn’t
exactly take the world by storm. It was just too niche, too late, and full of compromises. Thanks for watching, and a big thanks to AmEv7Fam
on Twitter for bringing this device to my attention. I had no idea these were ever made, and find
the concept absolutely fascinating. If mostly questionable. I’m willing to bet, though,
that this device is just waiting for its own renaissance. I’ve thought for a while now
that it won’t be too long before the CD gets the same resurgence that vinyl and lately
the cassette have enjoyed. If and when that happens, maybe this is gonna make more sense than it ever has. ♫ combinational smooth jazz ♫ The compact disc was a truly revolutionary
product in a… oh I should totally be holding one And third, it would end up.. Ehh bibuduh It would up‽ Wound up! Underneath the dust cover you will find…
a very creaky dust cover Well, because the record sits so much higher
ah… Fah there’s a comma! This thing is in fact… Because this thing
is in fact a functional phonograph. Even though it’s not behaving right right now. Because this thing is in fact a functional
phonograph. [laughs] Ugh! Why is it doing this now? Ok, we’re gonna turn you off and
on again. Did you notice how I said "rather frequently" twice within like three sentences? I certainly did, but of course not during the MULTIPLE days of script work and revision. Only during the video edit, when it was way too late. So it goes.
Epic device! Thanks for the video. I hope I will own one one day, just for fun.
Video suggestion:
/u/TechConnectify
You could do a video on the error scanning functionality of optical drives, that measures the rate of correctable errors on discs.
More information about it:
Sadly, not all optical drive vendors support this feature, and most people are not even aware it exists.
Often times with videos like this, I'm like why does this exist? And then after watching it changes to wow that's really neat. Thanks u/techconectify
any video that lets me listen to discovision is a good video
It’s a shame there’s not a mechanism to lift the record so the CD arm can work with removing it.
There's an interrobang in the captions‽
Does this mean we will soon get to see the internals of a front-loading record player?
Am I the only one that watched and became curious about his age? Lol besides thinking that, even though I’m a 90s kid, I still grew up listening to both records and cds. 😂Great video as always!
Love the TMBG collection. I have to ask though.... was that a Weird Al reference at 11:27?
What is going on, did you get a camera man? The camera is moving! It's zooming in and out!
