CD-X
1985 – 1988
Retail price 485 euro in 1985
The CD-X looks incredibly futuristic with its touch screen buttons even today – imagine how it was received back in 1982! But would you believe that it was based on a Philips CD-104? Well of course you would, as almost every player of that time was based on a Philips player. Its seemingly flat profile would have one believe that a CDM-1 transport would never fit inside but if you look closely, the CD-X is less flat than it seems. Inside is a complete CD104, minus the loading mechanism and plus a two-fold flap operating mechanism, which is spread over the left most and right most side of the player. It’s still amazing that these units still work after all this time. DAC used is the TDA1540 14 bit unit with oversampling.
Sound
Soundwise the CD-x is very much like listening to a Philips CD104: smooth, colourful and very relaxed.
Below is a reprint from Beophile.com, an original ‘Gramophone’ magazine article:
Beogram CDX was a beautiful-looking free-standing compact disc player designed from the onset to be used within any system with the correct inputs. In the case of Bang & Olufsen products it was those which had a separate tape socket, or even a phono connection designed for use with a Beogram together with a built-in RIAA preamp.
The CD format in the early to mid-1980s was still a fledgling format. No one was particularly sure whether it was going to take off or not as the price of compact discs was still relatively high and the number of available discs very low. On top of that hi-fi manufacturers had just been through the VHS/Betamax/V200 debacle with many companies losing both face and money. Laservision was fighting a (losing) battle with other manufacturers of video discs and the whole market was very much up in the air. No one was really sure what was going to happen and manufacturers became a little coy when it came to investment in new technologies. Hence the use of other companies’ products came about. It was often a safer and cheaper option to use a tried and tested product rather than spend umpteen millions on the research and development of a product or a format which was possibly not going to sell.
Hence the use of Philips CD players came about. In the case of the Beogram CDX it was Philips CD104 which was used as a basis. Built in Belgium by the Philips giant the CD104 was one of a whole range of Philips’ products which lent themselves to other companies badges including that of the Marantz CD-34, the Mission DAD7000 and the Schneider CD1104. Not forgetting Bang & Olufsen’s CDX, of course.
The CDX was a lovely machine, reinventing itself as the Beogram CDX2 a couple of years or so later, and many fans of CD music owe thanks to this little machine. It’s interesting to note that for customers with no spare sockets avaiable to connect their CDX, an add on, the CD/Tape adaptor, could be bought separately allowing one to connect up their CDX to the tape recorder lead, using it that way. It fit under the side of the CDX where there is a small push-button to enable its selection.
YOU have to admire the way that Bang & Olufsen have steadfastly pursued their own ideas on styling, and produced over the years a range of smart-looking audio units which could never be mistaken for the products of any other manufacturer. This has given a welcome relief from the ubiquitous look-alikes in four-square black or silver coloured boxes, though it may have lost B&O a few sales in ’separates’ since their units present such a marked visual mismatch with the rest. However, their penetration into the local design-conscious Scandinavian market is doubtless healthy, as it is into countries like West Germany and to some extent the UK.
B&O designers also make up their own minds about what features and ergonomics the customer wants (helped by a panel of ordinary folk on whom all new designs are tried out) and this too leads to designs which have moved away from the norm.
The new Beogram CDX (as a GRAMOPHONE man, I was pleased to see B&O retaining the “gram” suffix for their CD player as well as their turntables) certainly looks and behaves a little different from the general run of CD decks. Except for two push-switches on the narrow front edge, all controls are of the touch-sensitive type and are embedded along with the illuminated displays behind a transparent top panel. The two push-switches are for mains on/off (labelled Play) and Eject.
Pressing the latter causes the machine-long lid to open, the inner compartment to be illuminated, and the disc-platform to be tipped forwards at an angle. In theory this slanting platform should simplify putting a disc into the machine, but I slightly prefer the usual horizontal holders (and of course the CD player industry has almost completely gone over to gliding drawer front-loading configurations to facilitate stacking with other hi-fl units) so here again B&O might be said to be out of line.
To play a disc from the beginning, you just lay a finger on the word “Play”, the lid closes automatically, the player registers the disc’s “Table of Contents” data, and then starts to play the music. The green LED display at the left hand side indicates the total number of tracks, with the current track number in play flashing. A red display on the right shows the track elapsed time, or can be switched to indicate the total elapsed time, or the track and index number.
Other controls are more or less standard, such as track skip (by touching Advance or Return) and track search (by touching the appropriate arrows) when the laser moves at one of three speeds; in steps of 1 second to begin with, then steps of 10 seconds and finally, if you keep your finger on the arrow, steps of 1 minute. To play any particular track, you touch the required number (or pair of numbers for higher track numbers up to 99). Programming a sequence of tracks is done by touching each desired track number followed by ‘Store’, or conversely touching each number you want to omit, followed by ‘Clear’. In either case, the selected track numbers only will light up. Up to 40 items can be programmed in this way, including the same numbers repeated, so that a much longer total playing time can be set up than any single disc actually contains. There is also a Repeat function, for up to four times repetition of the whole disc, or a programmed sequence. Pause is obtained by touching ‘Stop’ briefly, and keeping your finger down for 2 seconds returns the disc to the start. Play is resumed by touching the word ‘Play’.

greetings from tulsa!
i picked up a pristine little gem in a 1985 cd-x. everything seems to operate properly except for the fact that it doesn’t emit any sound. i replaced the rca cables as they appeared to have had some damage but that didn’t change anything. i can even hear when i advance songs through headphones, but i can’t make out what song is playing.
might you have any other suggestion for where i could look.
i would really like to make the player work!
thank you for your time!
Hi Will, I had a CD-X that had the same issue as yours but only for the first 10 or so minutes. At a certain point, it started making music. As long as it was switched on, it played perfectly. I think this is the symptom of one or more capacitors gone off spec which I guess is only fair after 33 years:-). I couldn’t tell you which one(s), though, but a repair shop should be able to quickly fix this.
hi again christiaan!
i went back in and resoldered the connections and i got the same result. i’m back to finding a repair shop here in the states.
good news and not so good news. i turned it on and just let it play and yes it did finally come on after a little while of static, but i only get sound out of one side, not both.
Hi Will, I’m afraid that one or more capacitors will need to be replaced indeed. But probably that’s all! I live in the Netherlands and can only help suggesting a good shop in the Netherlands, I’m not informed of those in the UK.
hi again christiaan,
in doing a little more research and with a little more input from other audiophiles, i’ve come to conclude that it will need a reed relay or two replaced. do i have the guts to give it a try?? if i can find them locally i may give it a shot. or i may just listen to the machine as it is. probably not though. i didn’t realize there’s a place advertising on your site in california. i’ll contact them if i loose the will to continue working on it… your info has been very valuable and as we speak (or type) i’m ordering one of the wooden bull turntable mats! you’re a gentleman christiaan!!
cheers my friend!!
will
You’re welcome! By the way, the relays may not be operating but that might still be caused by one or more capacitors gone off spec. There’s no need to replace them either way. You could bypass the relays’ switching pins to check but be careful not to short its power supply pins. The relays are only there to stop you from hearing pops through the speakers at power up/down and potentially to disconnect the signal in case of a fault but that’s probably too fancy for a player this old. At the end of the articles there’s Google Adsens which shows ads appropriate to the person reading the page so if you have search history showing for it then it makes sense that you are shown repair shops:-) I have no affiliation with Wooden Bull but can definitely recommend the mats. I use them on all my pivot arm players.
hi christiaan,
i haven’t tried leaving it on for a period of time and then playing. i’ll give that a try now. i haven’t found anyone around me that wants to give it a look at. might you recommend a trusty repair shop maybe?
thank you again for your time and input!
hi again christiaan,
call me a glutton for punishment i guess.
i came across ANOTHER cd-x here locally and picked it up very reasonably priced. knowing what i do now, i placed a cd in it and of course no sound. i let it play for a period of time and viola, it was playing. now here’s the funny part. i’ll turn it on and it may play just fine, or, it may not read the cd, or it may play and it sounds like it needs a new belt to drive the mechanism. i do have the other one that sounds fine so i may switch belts (if they do indeed have them, i haven’t checked that yet). AND i came across another cd-x here in town as well. call me crazy, but i may go pick that one up as well! i love these machines and will have one (or more) working before it’s all said and done!!!
on another note, the wooden bull pad should be here this week! i’m very excited to see it. this one is a gift for a co-worker but i’ll be ordering a handful of them for me if it’s as i’m expecting. john from wooden bull is a class act and i want to express my gratitude for turning me on to that product!!
cheers again from the u.s.!!
will
Hi Will, glad to hear that it looks like you’re going to get this sorted. BTW the CD-X has a belt-free swing arm mechanism, see photos above.
hi christiaan,
well, i was looking for a belt in the photos above and didn’t see one. i haven’t taken the time to open the machine up. i hear a kind of a little thumpy noise when it plays and when it acts up it is in time with that thump (for lack of a better word). i’ll be taking the bottom off this weekend and seeing what i can make happen.
again, your time and responses have been like magic to me and i’m very grateful!
have a great rest of your week!
will
Hi Will, hi Christiaan,
Seems I’m a lucky guy. Also got a CD X for a very fair price and… IT WORKS without a hitch! After some cleaning of the surface this CDP is now my main aggregate.
Meanwhile, I own as well (and with a little proud) a Marantz CD273, a Philips CD473, a Philips CD650 (obviously with dead caps in the CDM2/10), a Philips CD380, a Philips CD630 and a Philips CD614.
Although TDA154x are the best DACs I’ve ever listened to Beogram CD X beats them all. I guess weight DOES matter.
I decided to mod the CD630 by replacing the SAA7220P/B with a NOS module as everyone is telling me that this will take me to a completely new audio experience. I’m curious.
Nevertheless, the Beo is and will be the eyecatcher in my equipment.
Good luck @Will and many thanks again Christiaan
Hi Heiko, nice to hear that you found a perfect CDX. While I can agree that the B&O does indeed sound very nice and indeed better than many other TDA154x DAC-based players, this is not only due to weight. Among others, it comes down to the design of the power supply and output stage and the transport itself also have a very large influence on the sound. Especially the state of the transport and its caps has a very large influence on the CD player’s sound. For example, I owned two Marantz CD94’s and found them to sound very different. The better one was indeed the most recent and least used one. It’s a bit of a never-ending story with all the variables, but that’s part of the allure:-)
Hi Christiaan,
you’re absolutely right. The CDM is made of iron. But that’s part of the weight, together with some other parts of the CDP.
