BeoSound 9000

Bang & Olufsen BeoSound 9000

BeoSound 9000 makes a strong statement with your music – but leaves it up to you to decide exactly how.

Music may not be essential to life, but it’s hard to live without it. That’s why BeoSound 9000 makes such a big thing about bringing your music out into the open and letting you create your own personal jukebox with the music that means the most to you. Combine BeoSound 9000 with the latest Beolink® PC 2 software application and you can access the digital music files on your computer’s hard disc. Place it upright in a bookcase, lay it flat on a shelf, or hang it directly on the wall – either vertically or horizontally. It can stand between a pair of BeoLab 1 or BeoLab 8000 loudspeakers, or with any other speaker in the BeoLab range. With BeoSound 9000, the possibilities – and the enjoyment – are endless ” (B&O Catalogue 2001 – 2002)

BeoSound 9000 represents the latest technology from Bang & Olufsen today. The 6-CD changer is the fastest in the world. If allowed to continue its momentum it would travel 100km/h in just 5,5 seconds… faster than a Ferrari from a stop position! It can be positioned in several different ways and the display text automatically adjusts itself to be readable. The unit too features a FM/AM tuner with RDS and is equipped with the new MasterLink connections and can be connected directly to the Beovision Avant and AV9000.

The CD returns to its original position
The discs are easily loaded and held by spring suspended jaws. Discs not in play can be replaced without interrupting the playback. The auto-positioning feature ensures that CDs are always returned to the position in which they were first placed. With the CDs visible and positioned correctly, there is easy access to the text information printed on the label. The glass-covered natural aluminium plate holds the CDs and the rails for the CD carriage, while a backlit acrylic plate illuminates the CD currently playing.

Glass cover to counteract gravity
BeoSound 9000 offers unprecedented flexibility for a product of this type, and to ensure the same uniform movement of the glass cover regardless of the placement of BeoSound 9000 vertically or horizontally, upright or flat. To counteract the effect of gravity, a digital time control constantly monitors the movement of the cover and adjusts the motor, keeping the complete movement within 3.5 and 4 seconds.

Safety first
Such an abundance of fast moving mechanics means that special measures have been taken to ensure that BeoSound 9000 is safe to operate. Small prismatic lenses are placed at each end of the aluminium frame, controlling an infrared beam across the front of BeoSound 9000. If the beam is violated, the CD clamper will stop immediately.

If the glass door is lifted while the clamper is in motion, it will decelerate immediately. A power failure feature ensures that the clamper is not damaged in a gravitational free-fall, if BeoSound 9000 is mounted vertically.

Ingenious engineering solutions and intricate mechanical movements in a product that continues to surprise and delight users today – and all this from the inspiration of old vinyl records spinning on the record player’s turntable.

The unit may be played in one of seven different positions. In each one, gravity has a different effect on the CD clamper (the aluminium ‘arm’ which rests over each CD when it is being read), yet it still works with the same precision and speed: a good example of how Bang & Olufsen uses technology to overcome acceptable limitations. Place BeoSound 9000 upright in a bookcase, lay it flat on a shelf or hang it directly on the wall – either vertically or horizontally. It can stand, for example, between a pair of BeoLab 1 or BeoLab 8000 loudspeakers (as above), or with any other speaker in the BeoLab range. With BeoSound 9000, the possibilities – and the enjoyment – are endless!

BeoSound 9000 starts with the technical excellence of the CD, but moves on from its limitations. A couple of good old-fashioned mechanical virtues make a welcome comeback. You can see it work and understand how it reacts when you touch its buttons. Or you can sit back with your Beo4 remote control and browse through over 7 hours of musical pleasure.

BeoSound 9000 makes a virtue of displaying the features that so many manufacturers try to hide away” welcoming the user with open arms to use it.

Features
BeoSound 9000 works so fast and so quietly that the change-over between two CDs seems no longer than the normal interval between tracks. Using the inaudible initial lead information on the discs, each CD can be named and memorised, and will be left in the same position as it was loaded, with its title clearly legible. Enter up to 200 titles in the memory and they’ll appear on the display whenever one of those CDs is played.

The FM/AM radio has memory for up to 60 stations which can be identified by their names instead of their frequency numbers. Set the timer and wake up to your favourite programmed CD sequence or radio station.

The fine art of control of BeoSound 9000
Lift the lid on BeoSound 9000 and the extensive control panel with timer, editing and sound adjustment operations is at hand. Since the BeoSound 9000 can be placed in a great number of positions, the control panel can turn as you prefer. The display follows the same orientation, of course!

Auto Positioning
Auto-positioning was one of the challenges that Bang & Olufsen’s engineers had to meet because of BeoSound 9000’s clear versatility in placement. Using the inaudible initial lead information present on most compact discs, the BeoSound 9000 is able to detect and memorise a desired position for the CD.

When it’s time to stop the CD, a servo system decreases the speed of rotation, the position mark is detected, and this effects the final braking and halt. A servo calculates the braking length for the CD, processes and stores the information. So the next time the CD will stop even faster, because BeoSound 9000 now knows where and when to apply the brakes. A total of 360 perforations ensure that your CD will stop precisely at the point at which you placed it in the rack.

The secret behind the precision of the movable clamper lies in two sensors which monitor its exact position and speed more than 60 times a second, and in its digitally-controlled motor, which compensates for even the slightest variation in movement.

Note: For owners of BeoSound 9000 who wish to use BeoLab 5 with this particular CD player, another feature of these new active speakers will be a direct digital feed from the optical output of BeoSound 9000 – the output not used at present!

BeoSound 9000: an evolutionary movement
Since the early days of the gramophone, record changers have been known and appreciated for their long playing time. The modern version of the record – the CD – adds a new perspective to the old old idea.

In designing BeoSound 9000 from scratch, a number of design models were created in order to illustrate various ideas.

The ‘library machine’ was one of them. It could hold an entire CD collection ready for playback. However the stored discs disappeared out of sight into the innards of the machine. This was seen as a problem because compact discs are not able to give a readout of a library’s contents, making an automatic catalogue display impossible, and since the design group felt a primary manual entry of all CD data was out of the question, the idea was quickly abandoned.

In returning to square one, the dominating feature – as in a CD changer – is the ability to play continuously for a long period of time. In coming up with a solution for this problem, together with presenting visual feedback, the discs were placed with their covers upwards and in a line next to each other, protected, under a lid of transparent glass. This was the main idea behind the very first design model of BeoSound 9000.

However, David Lewis, as Bang & Olufsen’s chief designer presented the first design model of BeoSound 9000 in two editions: the one which we know today with its 6 CDs, as well as another model comprising ten compact discs laid out in a line next to each other (see picture above).

The design group liked the 10-CD edition; it looked stunning, but in use it was limited to just once placement (unlike the eight different placements that the currently-produced BeoSound 9000 offers). The 10—CD version was subsequently shelved with the 6-CD version going into production in 1996.

David Lewis’ BeoSound 9000 from 1996 makes a virtue of showing its function. It clearly displays, by the 6-CD slots, that its function is the playing of music It can be placed horizontally on a wall or vertically on a special column when it becomes almost a sculpture for the home. Like B&O’s other products BeoSound 9000 contains the most advanced techniques around but shies away from technical mystique with its interface being simple and self-explanatory.

Control
Lift the lid on BeoSound 9000 and the extensive control panel with timer, editing and sound adjustment operations is at hand. Since the BeoSound 9000 can be placed in a great number of positions, the control panel can turn as you prefer. The display follows the same orientation, of course. BeoSound 9000 may also be controlled by the optional Beo4 remote control.

Placement
On the optional bracket, the BeoSound 9000 displays itself raised at an angle, or standing tall. Attach it horizontally and watch all the CDs stop in exactly the same positions as they were loaded in. Or you might opt for the floor stand as a bold musical statement. Hang BeoSound 9000 vertically on the wall and see how the display automatically changes orientation if you reverse the control panel.

Internet Music
Combine BeoSound 9000 with the latest Beolink® PC2 software application and you can access the digital music files on your computer’s hard disc directly from your music system in the living room. And if BeoSound 9000 is part of a Beolink® setup, you can enjoy your virtual music collection in any room in the house.

Auto positioning: stopping in the same place every time
Six CDs presented neatly in a row, with all the titles legible. After playback, BeoSound 9000 simply stops its CDs in exactly the position in which they were first loaded.

Auto-positioning was one of the challenges that Bang & Olufsen’s engineers had to meet because of BeoSound 9000’s clear versatility in placement. Using the inaudible initial lead information present on most compact discs, the BeoSound 9000 is able to detect and memorise a desired position for the CD.

When it’s time to stop the CD, a servo system decreases the speed of rotation, the position mark is detected and this effects the final braking and halt. A servo calculates the braking length for the CD, processes and stores the information. So the next time the CD will stop even faster, because BeoSound 9000 now knows where and when to apply the brakes. 360 perforations ensure that your CD will stop within just 1° of the position in which you put it on!

BeoSound 9000’s CD reader is propelled back and forth by a powerful motor. An optical system allows a microprocessor to monitor the reader’s movement between the six CD stations. The total distance of 63 cm is divided into 1,040 separate positions so that the reader can be positioned to an accuracy of just 0.6mm. Given that the reader accelerates from 0 to 100km/h in just over five seconds, it’s vital that the electronic and mechanical components are in perfect harmony. BeoSound 9000 is one of Bang & Olufsen’s most compact products, housing no fewer than 2,910 different components.

Mounting Options
Bang & Olufsen boasted 6 mounting positions for BeoSound 9000 from the range of stands and brackets launched with this super flexible icon. The table stand and floor stand were complimented with a pair of wall brackets giving the choice of horizontal or vertical mounting

BeoMaster 1001

Bang & Olufsen BeoMaster 1001

This top-operated receiver was not just exciting in appearance, it was also designed to facilitate operational comfort.

Primary controls were easily accessible, while the rarely used secondary regulators were concealed. The large tuning scale had calibrations in MHz and channel numbers. Tuning accurately to a desired station was child’s play because the large transparent slider was also provided with three small thumbwheels which assisted fine tuning.

Your three favourite stations could be pre-set by individual controls which were safely concealed beneath a sliding panel on the upper right hand side of the set. Subsequent programme selection was by easy pushbutton. The use of Field Effect Transistors (FETs) and Automatic Frequency Control (AFC) ensured optimum FM reception and compensated for weak signal conditions during tuning.

The amplifier’s power output was 2×15 watts RMS or 40 watts total music. Ambiophonic reproduction could also be obtained simply by connecting four loudspeakers, 2 in front and 2 to the side. In this way you could obtain an ‘extended’ stereo reproduction, a more realistic recreation of musical experiences recorded, for example, in a concert hall, because ambience or room information were included as well as direct musical information. There was a push button, the ‘ambio filter’, by which you could damp or reduce the highest tones (treble) reproduced in the side speakers. This was sometimes desired since the reflected sound which is reproduced in the side speakers is mostly mid-range tones. By damping high tones in the side speakers you could obtain a more natural sound reproduction.

Balance regulation was solved in a unique way in Beomaster 1001. Volume was controlled by two sliders, one for right and the other for left channel. The two sliders cold be operated together with one grip or separately, so that the balance between the channels could be adjusted as desired. The receiver’s slim, compact cabinet allowed several playing positions. Mounted on a wall (with special mounting bracket), slightly slanted (by special supports fitted to its base), or the traditional horizontal position. There were connections for record-player (switchable between high and low ohms), tape-recorder, headphone and four loudspeakers. A light indicated when the receiver was switched on, when the FM programme source was in use and whether a programme was in mono or stereo.

Receivers and amplifiers with the ambio function were products which, apart from stereo, could also reproduce the ambience or sound information of a room. Ambient information was included on most stereo vinyl recordings but could not be reproduced by a sound system with two loudspeakers or an ordinary stereo amplifier. Bang & Olufsen systems with the ambio function had facilities which electronically subtracted the difference signal (i.e. the difference between left and right channels) which contained ambient information. This information was fed into two extra loudspeakers which were placed as side speakers in a room. Ambiophony was an extension of stereo reproduction and enhanced the sense of realism. It could be used with nearly all stereo programme materials.

FM room aerial
In order to receive FM programmes, an FM aerial must be connected to the Beomaster 1001. Within a certain radius of the transmitter you could use the Bang & Olufsen FM room aerial, type 8902010. This aerial was easily fitted and the telescopic elements could be pulled out and positioned favourably.

Wall mounting
If desired, the Beomaster 1001 could be mounted on a wall by means of a special bracket. type 8920243. The bracket was screwed onto the wall and the receiver easily hung in position.

BeoMaster 1200

Bang & Olufsen BeoMaster 1200

The Tombstone: The simple, modernist graphic is the essential element in Jacob Jensen mechanical designs for Bang & Olufsen. The type-face used on the surface is Helvetica, popular in the post-War era and used by many publications today. The Beomaster was only a plate with an inscription and so it was given the sobriquet of ‘The Tombstone’.

“The Danish Press in 1967 referred to the Beolab and Beomaster 5000 as a “cinema system in two cigar boxes”. With the Beomaster 1200, which was aimed at a broader sector, B&O were ready to go the whole hog and abandon all known notions as to how a radio receiver should look. The reduction was absolute: to a wooden frame around an operating surface. The body of the apparatus disappeared, and only a small cooler grill at the top serves as a reminder of the contents. The totally top-operated equipment can be hung vertically on the wall as a decoration along with the simply framed art products of the time.

This is a slide rule gone mad. The knobs have become part of the polished aluminium surface – flush”! However, not only have the knobs been made flush with the surface, but superfluous functions have also been removed. For Jensen design is a question of considering the consumer’s functional needs. Five permanently set stations are selected below the aluminium sheet in the right-hand corner; user friendliness in everyday life is at the heart. The compact technology has turned the designer into a fashioner of operating aggregates.” — taken from ‘Jacob Jensen’ by Christain Holmsted Olesen.

Beomaster 1200 – type numbers 2501, 2503 – was, at the time of its introduction in 1969, one of the world’s most modern-looking and sophisticated receivers. It incorporated an amplifier around an FM/AM tuner. Radio stations could be tuned in by means of a sliding scale. The format of Beomaster 1200 was to set the trend in Bang & Olufsen design for many years to come.

Beosystem 1200 – made up of Beomaster 1200, Beocord 1200 and Beogram 1200 was the second of Bang & Olufsen’s first ‘designed’ system. The very first was Beosystem 1000 in 1965. The design ‘kinship’, which emphasised the interdependence between B&O’s various products, became a characteristic of B&O for many years. Beosystem 1200 was one of the first products selected by the Museum of Modern Art for the museum’s permanent collection (not exhibition) in 1972.

In 1969 the Danish Society of Industrial Design awarded Bang & Olufsen and Jacob Jensen the ID prize for the Beomaster 1200 radio/amplifier, Beogram 1200 turntable and Beocord 1200 cassette recorder for unusually beautiful and user friendly design. The jury emphasised in particular the Beomaster 1200 receiver which pointed in a new direction for the design of radios.

And the year after, three Bang & Olufsen products designed by Jacob Jensen received the IF award. The winning products were: Beomaster 1200 tuner/amplifier, Beomic 2000 microphone and Beolit 600 transistor radio.

“Congratulations! Well, we have done this before”, said Prince Henrik – The Queen of Denmark’s husband – when he presented the Danish ID award of the Society of Industrial Design to Bang & Olufsen, represented by Jacob Jensen, the designer. The remark made reference to the fact that B&O had also received the award the year before.

In Jacob Jensen the Museum of Modern Art in New York (MoMA) chose seven Bang & Olufsen products designed by Jacob Jensen to be included in their Design Collection as representing excellent examples of the Museum’s criteria for quality and historical importance; design, in fact, which had influenced the twentieth century. Beomaster 1200 was one of those seven products.

The 1200 series represented the logical continuation of the line of development and design which put B&O at the forefront of manufacturers of entertainment electronics. The receiver was superseded by Beomaster 1001 in 1973.

These are superb looking receivers and are especially impressive when wall mounted. However to sound at its best, it really does need to use the recommended loudspeakers. With more modern speakers, the 1200 can sound a little weak and lacking in detail. The provision of Beovox 1200 speakers however reveals very satisfying performance. This is one of many examples where B&O have clearly designed a system.

BeoMaster 1700 (1980)

Bang & Olufsen BeoMaster 1700 1980

Beomaster 1700 was an AM/FM receiver in a class of its own. It was defiantly different when most high fidelity components still tended to look alike. Different in its design, its use of technology and the benefits it offered.

The FM section had facilities for presetting 5 favourite stations which could then be tuned instantly by pressing a button. The AM section covered both the Long and Medium wavebands. Hybrid filters were used to achieve high selectivity (the tuner’s ability to discriminate between the desired station and unwanted stations adjacent to it)The stereo amplifier was rated at 2 x 30 watts RMS with high quality sound reproduction up to the last watt. The tone control circuits were designed so that they could not limit or distort the quality of the reproduced sound before the amplifier’s maximum output level was reached.

All in all, the quality and performance levels of Beomaster 1700 were beyond reproach. As they should be, with the best technology. But what was most interesting was the creative use Bang & Olufsen made of technology – a (then) new operation system which afforded sharp, precise settings that were easy to locate on the scale. Two flexible slider controls formed the centre of this operation system. One was used to regulate volume level, bass, treble and speaker balance. The other was for the precise tuning of stations on Long, Medium and FM wavebands. The sliders had a sensitive, ridged surface that prevented the finger from slipping during operation.

The set’s large glass-covered communication surface, with its clear graphic indications aided easy operation. During use, response was light and immediate. Illuminated markers – light emitting diodes – kept you informed of the set’s operational status at all times. The surface was easy to clean with no irritating dust traps.

A Beogram 1700 and two Beovox C40 hi-fi loudspeakers complemented Beomaster 1700 in creating the well-balanced Beosystem 1700.

Well the above is the official line seen in the brochures. What could not be denied was the design of the 1700 which was innovative to say the least. I some ways it resembled the Beomaster 6000 quad except that it had a manual mechanism and clutches instead of the electrical control of the 6000. It gained a decent glass panel instead of the perspex of the 6000 but was let down by very poor quality plastics in the clutches, tractor drives that slipped and broke and an amplifier which was indirectly coupled compared to the direct coupled 1500 which it had replaced. Although it looked better than the 1500, it could not get close to the performance. Perhaps the beginning of a range designed more for looks than performance.

BeoMaster 1900

Bang & Olufsen BeoMaster 1900

The 1970’s were exciting times for Bang & Olufsen. Another breakthrough during this decade was Beomaster 1900, a radio receiver and amplifier launched in 1976. Once again, design and operation differed dramatically from other contemporary products.

Originally designed by Jacob Jensen, Beomaster 1900, together with Beomaster 2400-2 were two advanced FM stereo receivers. They had identical technical specification and performance. Both were easy to use and easy to live with. Beomaster 2400-2 had the additional convenience of a cordless ultrasonic remote control module by which you could operate radio, amplifier and Beogram 2400 or 4004 record deck from a distance. Both receivers had touch-sensitive controls for operating the features and functions you used every day. All the secondary switches and adjustments were protected beneath a hinged lid, but an illuminated readout panel showed you the set’s operational status at a glance.

Beomaster 1900 boasted a powerful 2 x 30 watts RMS amplifier with distortion of less than 0,13%, five pre-set FM stations and comprehensive connection facilities. To operate it you simply touch the application “dimples” on the set’s front panel. The radio section had 4 pre-set stations which could be summoned at a touch and the phase-lock loop decoder provided excellent stereo separation even in difficult reception conditions The volume level could be pre-set at low, medium or high, and the music would always start at this level however much the volume control was altered last time the set was used.

The sets’ controls were divided into primary and secondary functions. The latter, which were less frequently used, were placed underneath the hinged aluminium panel where they were protected from dust and accidental movement.

A clear distinction was therefore made between the primary choice – accessible through a light touch – and the secondary choice, concealed under a lid hiding what the user did not need for daily use. At a stroke, what had been the norm for hi-fi in the past, with its macho grip and buttons, was eliminated. Instead, designer Jacob Jensen created a new design language, flat ‘flush-designed’ and electronically communicating, which did not target a few techno-freaks, but a much wider audience who wanted music rather than hi-fi equipment.

Beomaster 1900 had connections for two pairs of speakers, headphones, record player and cassette recorder. The receiver won the ID Award in 1976.

BeoMaster 2000 (1974)

Bang & Olufsen BeoMaster 2000 1974

Beomaster 2000 at the time of its introduction in 1974 was an all-new model. The FM/AM stereo receiver was constructed to facilitate simple, logical operation.

Five FM stations could be pre-selected. Secondary controls which are not used daily were hidden under sliding panels. For example, the five FM pre-selectors, controls for AFC and muting (silent tuning), were discretely hidden away from view until such time as you needed them.

The construction of the stereo decoder was based upon a phase lock system which ensured constant high separation of channels. Manual tuning on the large FM/AM tuning scale was by means of a plain circular disc which was flush-mounted into the control panel. The tuning scale was illuminated and a light indicator assisted accurate tuning on an FM station. The AM section, (long and medium waves), had ceramic filters which enabled good separation between stations.

The newly developed automatic volume control effectively achieved a good balance between the weak and the strong AM stations. Darlington output circuits in the amplifier section produced 2 x 40 watts RMS or 150 watts total music, with less than 0.1 % harmonic distortion. One of the TAPE connections facilitated AB monitoring. It was possible to copy from one tape recorder to the other without having to fiddle with cables and sockets. There were sockets for two pairs of loudspeakers and for stereo headphones.

Two tape recorders could be connected and could be switched to enable copies of tapes to be made, in either direction. The set was housed in a large flat cabinet of a similar style to the Beomaster 1200 range, though the ‘slide rule’ pointer was replaced with a conventional dial, operated by a large flush aluminium wheel. A flywheel beneath this made manual tuning very smooth and the large diameter of the control, coupled with the now familiar dual light tuning indicator, also made it very accurate.

To complement slim appearance of the cabinet, a wire prop at the rear could be folded down, tipping the whole machine forward slightly enabling the controls and lights to be viewed more easily.

FM room aerial

Within a certain radius of the FM transmitter you could use the Bang & Olufsen room aerial, type 8902010. The aerial was easily fitted and the telescopic elements positioned as required.

This is one of the forgotten Beomasters. It utilised an amplifier design that would prove to be the most successful for B&O. It formed the basis for all the great amplifiers to follow in the range. Wonderful control of bass and plenty of reserve.

BeoMaster 2200 (1977)

Bang & Olufsen BeoMaster 2200

Beomaster 2200 was a 2 x 40 watts RMS FM/AM receiver with logical operation and high reliability.

Operation controls were separated into primary, secondary and tertiary functions. The primary functions – those you used every day – included programme selection, volume control and the off switch. They were easily accessible on the outside of the set. The secondary controls were under an aluminium panel. These included facilities for presetting 5 FM programmes; balance and tone controls; AFC (Automatic Frequency Control facility – which keeps stations properly tuned) and a mono/stereo switch. The tertiary functions, which were also hidden but easily accessible, were the connection sockets: you could make all connections for a record player, cassette deck, headphones and two pairs of speakers without moving the set.

Beomaster 2200 had a modular chassis. The modules were connected by wire-wrapping – a construction method that enhanced the product’s quality and reliability. This technique was originally adopted from computer production. The technique replaces conventional soldering, thereby eliminating any weaknesses arising from dry-joints, drop-outs and so on.

Volume adjustment was by means of a small slider along a numerical scale. Secondary controls included AFC (Automatic Frequency Control) coupled with silent tuning (AFC/ST), FM presetting dials for the radio, mono/stereo selection and loudspeaker switches.

These were all mounted beneath a hinged lid which opened when the PROGRAM panel was touched. A further compartment housed all the connection sockets which were easily accessible from the front of the unit. There was therefore a distinction between the functions which are frequently used, those that are used only once in a while, and those that would have been used a very few times during the set’s life.

The primary functions were for selecting the programme source, controlling volume and switching the set off – so these were the only controls that were on the outside of the set.

Beomaster 2200 could be made up as part of the Beosystem 2200, when linked together with other compatible Bang & Olufsen products.

BeoMaster 2400

Bang & Olufsen BeoMaster 2400-2

Beomaster 2400 together with Beomaster 1900 were two advanced FM stereo receivers. They had identical technical specification and performance. Both were easy to use and easy to live with.

Beomaster 2400 had the additional convenience of a cordless ultrasonic remote control module by which you could operate radio, amplifier and Beogram 2400 or 4004 record decks from a distance. Both receivers had touch-sensitive controls for operating the features and functions you used every day. All the secondary switches and adjustments were protected beneath a hinged lid, but an illuminated readout panel showed you the set’s operational status at a glance.

Equipped with the slim remote-control module you could select between four pre-set radio stations or record player input, adjust the volume up or down or put the System into Stand-by. The illuminated panel with its large display allowed to to easily see the state of play from anywhere in the room. The phase-locked loop decoder ensured a wide separation between stereo channels and remained stable over a very long lifetime. When a stereo broadcast was received, a symbol ‘S’ lit up automatically on the fascia of the set. Automatic Frequency Control (AFC) kept the selected radio station spot on tune, and a muting circuit cut out inter-station noise during tuning.

The stereo amplifier produced 2 x 30 watts RMS of high-fidelity output and had DIN sockets for the connection of two pairs of speakers, a record-player and a tape or cassette recorder.

A headphone connection was provided beneath the front edge of the unit. Controls not needed every day were situated beneath a hinged lid. These included tone and balance adjustment, FM pre-setting, loudness, AFC and MONO/STEREO switches, and a switch for selecting a basic initial volume level. This facility allowed you to choose the volume at which the amplifier began to play each time it was switch on – no matter how controls were left the previous time. On its primary control panel Beomaster 2400 had no knobs or buttons. The panel functioned electronically and needed only the contact of your finger to activate it. However, the ultrasonic remote control would have proved more useful. The set’s sophisticated indicator system would tell you instantly that your commands had been obeyed.

Beomaster 2400 was superceded by Beomaster 2400-2 in 1980.
