Beocord 8004 had its own microcomputer which took care of most of the tasks involved in recording and listening to cassette tapes. The microcomputer was also responsible for one of Beocord 8004’s most advanced and unique features – the real-time tape counter. Actual minutes and seconds were used to measure elapsed time so you always knew how much recording time was left to fill.
Selection between chrome, ferric and metal tape characteristics was automatic. So was the operation of the HX-Professional recording system – a technique developed by Bang & Olufsen to expand the peak ceiling level of all types of tape. The provision of Dolby B and Dolby C Noise Reduction improved the sound quality of your recordings even further.
Signal input levels were indicated on electronically-controlled Peak Programme Meters that performed to standards set for professional studio and broadcasting recorders. The signal level was monitored on both recording and playback.
The tape head of Beocord 8004 was a single combination head of superb technical quality. Both the poles and the beddings were made of Sendust alloy. As with all Bang & Olufsen recorders, a special additional circuit automatically demagnetised the head each time the STOP function was used at the end of a recording.
Locating particular recordings was quick and easy using the Beocord’s computerised tape address system. Just key in the track’s start time – in minutes and seconds – press GO, and wait a few seconds. The tape automatically wound to that location and began to play.
For recording an important broadcast while you were out of the house (or when you didn’t want to spend the evening clock-watching) there was a twenty-four hour electronic timer. With a few touches to the programming buttons you could store the station, start time and stop time in the microcomputer’s memory. It then carried out your instructions at the appropriate hour – regardless of how you used the recorder in the interim.
Beocord 8004 could be used as a stand-alone tape cassette recorder or as part of hi-fi systems such as Beosystem 6000 or Beosystem 8000.
A top-quality cassette recorder, perfectly matched to Beomaster 5000 as part of Beosystem 5000. When the two units were used together the cassette deck could be operated entirely by remote control.
Beocord 5000 was of very advanced design in both its technical features and in its control/operations systems. For the home recording enthusiast it offered superb standards of sound quality and precision engineering. Bang & Olufsen’s patented HX PRO recording system, Dolby B and Dolby C Noise Reduction and a 6-layer Canon combination head with a 1.8mm gap all contributed to a recording and playback performance that delighted even the most exacting technician.
For the novice or the non-technical music lover, Beocord 5000 represented a supremely straightforward way of making high-quality recordings and subsequently enjoying them in relaxing comfort.
Every possible convenience was built into the Beocord’s control system. There was a START/GO function that rewound the tape to its beginning and played it without further instruction. And an automatic ADVANCE function (tape search) that found the start of any required track from either end of the tape.
Selection between ferric, chrome and metal tapes was fully automatic, and setting the correct recording level was quick and easy using the input sliders and LED signal strength meters. You could switch instantly from one tape transport mode to another (e.g. from play to fast rewind) without any danger of tangling the tape or harming the mechanism.
The cassette tray and direct operation controls were housed in a motor-driven drawer which opened and closed at a touch. When used with Beomaster 5000, Beocord 5000 could, of course, be programmed to record or play automatically at any set time.
Connections: stereo microphone (DIN); Aux input DIN; data-link to Beomaster 5000 (one socket, 3-way switchable)
Top quality sound and maximum listening comfort were the main features of this integrated hi-fi system. Records, radio, cassette tapes and a 2 x 40 watts RMS stereo amplifier could all be controlled from anywhere in the room using the slim remote handset. Without moving more than a finger you could select any sound source, adjust volume level, fast wind the tape and even make recordings. This supreme ease of operation was made possible by microcomputer technology. In addition, there were two user-programmable microcomputers which allowed you to make unattended recordings at any time within a 24-hour period, or to play any sound source automatically at a pre-selected time – day after day, if you wished.
A further advantage was easy access to cassette recordings: just key in the appropriate counter reading (address) and the cassette would fast wind to the required passage of music. Ferric, chrome or metal tapes could all be used and Dolby B Noise Reduction was included to ensure clean, hiss-free recordings.
The automatic record deck had an ultra-lightweight arm carrying the MMC 4 pickup cartridge. The radio section covered Long, Medium and FM bands with facilities for pre-setting 6 favourite stations.
The recommended speakers were the Beovox S55 . Speaker pedestals or the SC70/ SC77 hi-fi cabinet could be added optionally if required.
In 1982, Bang & Olufsen introduced a completely new way of living with music. The company was then the only one in the world to fulfil the desire for perfect sound from attic to basement – from just the one central music system.
With the Beolink® system – around which Beocenter 7700 was based – you could enjoy and control you music system in several rooms. From acorns great oak trees spring, and most of the the current (2002) range of TV and hi-fi systems can be equally controlled to give you ’round the house music’ using the latest MasterLink system.
The very advanced (for its time) Beocenter 7700 system brought an entirely new range of possibilities to the serious music-lover. For the very first time ever, round-the-house hi-fi became an option, in whichever room you wanted to listen to it.
Beocenter 7700 featured Long, Medium and FM radio, automatic record deck, microcomputer controlled cassette recording and 2 x 40 watts RMS stereo amplifier. Two user-programmable 24-hour timers were included, and all sound sources are accessible by infra-red remote control.
From this comprehensive and desirable foundation, it was possible to build up (either immediately, or room by room) a sound system that could be enjoyed and operated from anywhere in the house ( a forerunner to the later Beolink® system).
This is how it worked.
The remote Terminal (Master Control panel) supplied with the Beocenter 7700 had control buttons for armchair access to all primary playing and recording functions.
But in addition, it also had three digital read-out panels on which your instructions were confirmed every time you pressed a button. So you had your means of “talking to” your Beocenter 7700, and it had a means of “talking to” you – right there in your hand.
Your instructions were carried to the Beocenter’s microcomputer by infra-red light, and confirmatory signals were returned to the remote control Terminal in the same way – in a fraction of a second.
This two-way communication could be extended to other rooms by fitting those rooms with a pair of speakers and an electronic Master Control Link, all available as optional accessories. When you wanted to listen to music or radio in a room away from the Beocenter, the remote control Terminal was taken with you. By directing it at the Master Control link (which you had fixed on the wall or on a shelf) in just the same way as you would normally direct it towards the Beocenter, you could control all primary functions and receive confirmation that the Beocenter was doing what you want.
The Master Link equipment could be fitted in up to four different rooms, and you could choose which speakers were to play and which were to be silent. It was like having a complete, top-quality hi-fi system in every room, but paying for only one (plus as many loudspeakers and Master Links as you needed). You could, if you wished, buy additional remote control Terminals if you didn’t want to carry one around the house. But this was not strictly necessary.
Beocenter 7700 offered top quality sound from records, radio and cassettes. Operation was fast, easy and foolproof because of a built-in microcomputer which blocked mistakes, automating many boring, repetitive operations – like switching off one sound source before switching on another. Two timers, each with a 24-hour memory and automatic repeat function, allowed you to record or play any programme at specific times – day after day if you wished. The digital clock could be displayed or not – it was up to you.
You could pre-set 6 favourite FM radio stations, or 5 FM and one AM (Long or Medium wave) for instant press-button recall – either by direct or remote control.
The cassette section had many advanced features to make recording easier and more accurate. Replay, too – it was necessary just to key-in the appropriate counter reading and the cassette would fast wind to any point on the tape. It was as easy as finding a particular track on a record.
Metal, ferric and chrome tapes could be used, and the Dolby Noise Reduction circuits ensured clean, hiss-free sound.
The record deck was fitted with the (then) very latest type of tone arm and miniature MMC 3 cartridge. This pick-up carried a tiny naked elliptical diamond and weighed only 1.6 grams. It had superb tracking ability and ensured the minimum of record wear.
The safe handling of records was also the idea behind the turntable light – fitted inside the hinged lid – which switched on automatically whenever the lid was opened, and stayed alight as long as the deck was in operation.
Beocenter 7700 was available in natural teak or rosewood finish. It measured 72cm wide x 9.5cm high (37.5cm with the lid open) x 38cm deep and could be accommodated in either SC.50 or SC.70 System Cabinet, available separately.
Your choice of loudspeakers for use with Beocenter 7700 was really a matter of listening and comparing the various Beovox models. Different households had different requirements – in size, in quality and in cost. Fortunately, with the Beovox range the choice was a wide one. Advice on speakers for the Beocenter 7700 included Beovox C40, C75, S45, S55 and S80.
Beocenter 7700 was introduced as a completely new way of operating a hi-fi system. A way which gave individuals the freedom to enjoy top quality sound all over the house; at the same time to control the music from anywhere in any room.
This was the world’s first high fidelity system that could be operated from another room. With the Beocenter 7700’s master Control Panel and and optional Master Control Link, you could control radio, record deck, cassette recorder and stereo amplifier even though you were in the kitchen or bedroom and the set itself was in the lounge.
So when you want music in another room, don’t move the hi-fi – just move the music!
A Master Control Panel (above) was supplied with every Beocenter 7700. It was used just like an ordinary remote control handset when you were listening in the lounge, close to your hi-fi system. It let you operate all sound sources and adjust volume levels without moving from the comfortable armchair.
Master Control Link was an optional accessory, like the additional loudspeakers you needed in order to enjoy your music in other rooms. The Link equipment consisted of two units – a discreet black box containing a mass of sophisticated electronic circuitry (which could be fitted out of sight behind furniture etc.), and a transceiver unit that was placed on a shelf or wall where it could pick up the infra-red signals from your Master Control Panel. The transceiver unit also let you switch the speakers in this room on or off, and gave access to programmes that were due to be played via the Beocenter’s automatic timers.
You could buy extra stereo speakers and Master Control links for one, two or three additional rooms, as well as enjoying the hi-fi system itself which you probably installed in the living room or the lounge.
The Master Link equipment was connected by cable ‘in series’, i.e. only the first extra room is connected direct to the Beocenter; the second extra room was connected to the first and so on, so wiring was kept to a minimum. And you could add each room one by one – as your needs changed or your budget allowed.
Designed as a perfect match, both physically and technically, for the Beomaster 2000, this advanced slim-line cassette deck was nonetheless a serious hi-fi product in its own right, combining a high-performance specification with supreme ease of operation.
Despite its unassuming appearance, Beocord 2000 contained a full pay-load of advanced circuitry plus a few extra features rarely found in cassette decks within this price frame. The primary controls – those concerned with tape movement – were totally electronic and designed on the Sensitouch principle. There were no knobs to turn or keys to press; a light fingertip touch was sufficient to activate any function.
Ferric, chrome or metal tapes could be used, and Dolby B noise reduction was included to ensure clean, hiss-free recordings. A clearly calibrated scale and input slider, together with large Peak Programme Meter, made it quick and easy to set accurate recording levels. These controls were placed adjacent to the cassette tray beneath a hinged lid which sprang open at a touch.
Beocord 2000’s built-in microcomputer made operation fast and foolproof. It was possible to switch directly between any and all tape transport modes without harming the tape, the mechanism or the motor. Microcomputer intelligence also opened the way for additional control functions that contributed in a very practical way to daily enjoyment of taped music.
A NEXT control allowed for easy track location (tape scan): one touch fast winds the tape to the next signal gap and plays the following track – automatically. So if you wanted to hear, for example, track number 5, just touch-and-wait four times and the place would be found for you. Similarly, you could repeat play-back of a favourite track up to five times with just a single touch. It’s such a convenient way of listening to exactly what you want, when you want.
Beocord 2000 had a socket for data-link connection to Beomaster 2000 so that direct switching was possible between Beomaster, Beogram and Beocord in the Beosystem 2000. The deck could also be data-linked to Beomaster 5000 or Beomaster 6000, when all tape functions could be operated via the receiver’s remote control system. Beocord 2000 could be made up as part of the Beosystem 2000, when linked together with other compatible Bang & Olufsen products. It was also part of Beosystem 3000 if that is how you wished to use it.
Beocenter 2200 was a distinctive high fidelity system offering 3-waveband radio, record player and cassette facilities in a very compact, slim-line format. Maximum power output was 2 x 25 watts RMS.
The radio section covered long, medium and FM bands. Four favourite FM stations could be pre-set for instant recall. A horizontal thumbwheel on the front of the unit controlled manual tuning: the large graph-grid tuning scale was very easy to see and use.
The record deck featured the (then) latest Bang & Olufsen tone arm carrying the ultra-light MMC 5 pickup. Operation was entirely automatic and needed just a single touch on the PHONO button. Built-in logic circuits identified the size and speed of any record placed on the lightweight turn-table and would cue the pickup arm onto the run-in groove with absolute accuracy and safety.
The cassette recorder had electronic control so you could switch directly between, say, fast rewind and PLAY without danger of straining the mechanism or damaging the tape. Dolby B noise reduction and automatic selection between ferric and chrome tapes was included. Metal tapes could also be used, so you were assured of top class sound quality for those really special recordings.
Listening to tapes was also quick and easy: the NEXT button allowed you to scan the tape track by track until you found the one you wanted to hear.
The recommended speakers for use with this system were the Beovox X25.
Connections: Mono microphone; 2 pairs speakers; headphones; external tape recorder with two-way copying; AM and FM aerials
Beocenter 2100 – three variations and a one-finger exercise
Beocenters 2200, 2100 and 4000 – each with a totally distinctive style but sharing the unmistakeable themes of Bang & Olufsen quality and simplicity.
If you loved true hi-fi but you weren’t a record fan, then Bang & Olufsen ‘had your radio perfectly taped’! Beocenter 2100 had all the features of Beocenter 2200 but without the record deck so that it took up even more of a conveniently small space.
Beovox X25 loudspeakers were the offered choice but you could equally mix and match the Beocenter with any other Bang & Olufsen speaker on the market at that time. When linked with Beovox X25 loudspeakers, the combined system was known as Beosystem 2100. A recommended record deck to complement your system would be either the Beogram RX2 or TX2.
As part of Beosystem 5500, this advanced tape recorder was as close to professional standard as could be made at the time, bristling with features you just loved to use!
There was Auto Reverse, letting you play or record both sides of a cassette as one continuous tape. And automatic adjustment of sound levels avoided annoying volume changes from one recording to the next. Then there was Bang & Olufsen’s famous HX-Pro recording system which gave vastly superior sound quality on the higher frequencies, creating a richer, more detailed sound image.
Beocord 5500 automatically adjusted itself to match standard, chrome or metal tapes. You had the option of Dolby B or C during recording. During playback, the recorder automatically switched itself to the noise reduction system you recorded with. Automatic track search was also included – just key in the track number and the recorder did the rest.
The cassette recorder could be controlled via the two-way Master Control Panel 5500 as part of the Beosystem 5500.
Auto Record level
One of the less-pleasant chores in making a recording is setting level control to its optimum position. Setting it too low raises the level of background noise on the recording. Setting it too high makes the recording distorted at high music levels. With this in mind, Bang and Olufsen introduced an automatic record mode which was called ‘Auto Record’.
Auto Record worked in two steps: when the record button was pressed for the first time, the cassette recorder went into a record pause mode, where the incoming signal was monitored. Under microprocessor control, the highest level was monitored and the record level was set at the optimum level for that music. On pressing the record button the second time, the tape was set in motion and the recording started, but continuing to make minor adjustments. If at any time during the recording, the level of music rose above the monitored level, the level control was lowered by exactly the amount required for the new optimum recording level.
This method of setting the level control closely imitated the action of a highly skilled recording engineer, if asked to set the level for a recording. It was the best that could be done when the full recording could not be monitored before recording started.
This feature incorporated a new method of monitoring the signal, which proved to be a more effective method over conventional methods. It was patented by the company with the patent number 158702.
At the base of the BeoLab Penta column was the BeoLab 150 amplifier with a power output of 175 watts DIN/IEC. This could give your music a tremendous boost, both to the quality and the actual power output. It was ideal if you loved to party but had a relatively small music system. Big power needs careful control – so the amplifier was equipped with Bang & Olufsen’s Dynamic Soft Clipping system. This was a circuit that prevented both distortion and damage to the speaker units by softly rounding off signals that were too powerful. Another circuit prevented damage due to prolonged overloading.
BeoLab 150: Controlled overdrive
On the amplifier itself were buttons for adjusting bass and the level of sensitivity. This meant that you could arrive at a permanent adjustment that matched the room exactly.
BeoLab Penta turned on automatically when it received a signal and also turned itself off three minutes after receiving the last signal. BeoLab Penta had a light display that indicated the volume level and which sound source the music was coming from. This was especially useful with Beosystem 5500 and Beocenter 9500.
BeoLab 150 and 200 were used as part of the BeoLab Penta active loudspeakers range.
Connections:
At the bottom of BeoLab 150 were two clip-sockets and a four pole DIN socket for connecting speakers, a line input phono socket and a mains cable.
A featherlight touch on the glass control panel brought up an illuminated display of numbers which corresponded to the tracks on the disc. You could select tracks in any order; you could see how long a track lasted and a motorised dust cover and automatic light were among the features that this stand-alone CD player possessed.
The CD player was based around the Philips CD104, built in Belgium.
As a standalone player, it lacked the Datalink and remote control facilities that its predecessor, the Beogram CD50, possessed. A good-looking CD player which performed well, it was later superceded by the Beogram CDX-2 in 1987.

If Beogram CDX is in standby position and there is a compact disc on the platter, one push at the PLAY button will start the playback.
If there isn’t a compact disc inserted, you push the EJECT button and the motor driven dust cover will open, the platter will lift and the compact disc can be inserted.
Apart from the above-mentioned PLAY and EJECT buttons, all operations are sensi-touch fields, which are operated with a slight touch.
When pushing the field PLAY, the dust cover closes automatically and playback starts.
The display indicates the individual tracks on the inserted Compact Disc. If it has more than 20 tracks, the two first digits in the time display will show the total.
The time display has 3 main functions, which can be ordered by pressing DISPLAY, namely the time of the individual tracks, the elapsed playing time and index, which is a sub-division of the time of the individual tracks.
ADVANCE and RETURN are used for jumping to the next or the previous track and are indicated with a flashing of the selected track on the display.
With the digits 1 to 0, a track can be selected at random and the jump is marked on the display.
With STORE and CLEAR you can select or leave out up to 40 tracks on the Disc.
REPEAT replays the Disc up to 4 times.
One push at STOP gives pause, and by keeping the finger on the field till the Disc stops, you get actual STOP. << and >> are used for fast search within the individual tracks.
When activating it once, you search in jumps of 1 second
By keeping the finger on the field you search in jumps of 10 seconds and after 10 seconds the jumps are 1 minute
Connection
Beogram CDX is provided with a fixed signal cable with Phono plugs and can be connected to all LINE inputs. For amplifiers with TAPE inputs which are already being used, we can deliver a CD/TAPE adaptor, type 8950060 (accessory at additional price)
1985 Magazine Review
” The CDX is one of two ‘Beograms’ which have been promised by B & O for some considerable time. It would seem that to a large extent B & O have edged, their bets, for the CDX is a Philips-based machine while the alternative model uses Sony-sourced assemblies. The CDX is an extraordinarily beautiful machine yet, as we shall learn, is based entirely upon the ever so humble Philips CD?101 (the same player as used by Meridian for the MCD conversion). The styling is obviously intended as match the other B & O units and so the company has an untapped market of existing owners who have been patiently waiting for a CD player. But it is a player well worth considering in its own right as a separate purchase.
Unusually the CDX is a top loader but the lid assembly is powered and in response to the eject button the lid assembly smoothly folds back to allow the disc to be loaded. With the exception of the Eject and Power switches, all the controls are touch sensitive (using a type of capacitive sensing) a choice which I found far from reassuring since I kept wanting to use extra finger pressure to ensure a good contact! My overall lack of confidence was further encouraged by the all black control panel which reveals nothing until the power is applied. Perhaps it’s too much like computer screen ‘soft keys’ for me for I kept wondering if the Play switch would be still in the same place every time I went back to this player!
Two types of display are provided; a digital readout to show track time, total elapsed play time, and track numbers up to 99; and a bar scale of 20 LEDs to show the status of the first 20 tracks. A reasonable range of facilities is offered with both track skipping and fast searching (both backwards and forwards). Tracks can be pre-selected for playback and programming is possible for combinations of up to 40 tracks stored in the memory. Finally a Repeat mode allows continuous playback of the whole disc or of individual tracks.
Once the CDX is opened some idea of B & O’s inventiveness can be gained. Into the plastic casing has been dropped a Philips CD101 player complete down to the signal and mains supply cables but less the Switch/Display board. Instead B & O plug in wires from their own front panel and wire connections to their Eject and Power switches. The whole conversion is very neat and since the Philips player is left unmodified all the standard parts fit thus ensuring ease of service.
It has to be said that providing the last word in performance is not needed; the Philips CD?101 is an excellent choice with the CDM mechanism being recognised for its good build quality and reliable operation (it is also to be found in the expensive Revox B225 player). The electronics design largely follows the familiar Philips circuit with 4 times oversampling conversion using a separate 14-bit DAC for each channel.
In the laboratory the performance was much as expected with a generally flat frequency response except for a mild dip of 0.25dB around 7kHz; very low noise (?104dB); low crosstalk between channels and quite reasonable linearity. No problems were experienced when using the error testing discs and this player did very well in playing back some of my badly scratched discs with very few garbled passages.
Auditioning was conducted through my usual system of passive control unit and Krell power amplifier with LC connecting cables. Essentially in terms of sound quality this was very much a case of re-reviewing a Philips CD101 (or Marantz CD63) and the expected high standards were
achieved. The sound can be characterised as open, exciting with a fine sensation of space and depth, and good stereo focus. The weaknesses were primarily at the extremes of the audio band with a warm, stodgy bass and a degree of harshness at high frequencies. However within the context of the B & O system the sound quality of this player would be considered quite excellent.
VERDICT: A beautiful model which will appeal to a wider market than just the traditional
B & O owner. The overall performance of the CDX is excellent and this player can be considered as good value
PROS: Good sound quality. Very good value for money. Beautiful looks
CONS: Rather fiddly to use. Old fashioned top loading ”
