This portable radio has a specification superior to those of most mains table models and is elegantly styled, with all the controls placed on the top panel.
The Beolit 1000 offers outstandingly fine reception: on all its five bands, distant stations tune in without noise and interference even when located on adjacent frequencies. The FM section features a separate dial drive and additional push-button selection of up to three pre-tunable FM stations. The extended Long Wave band includes the navigation bands, and on the SWII band (the ‘Europe’ band) you can find all the popular European entertainment stations. The built-in Short Wave expander permits you to spread stations for supreme ease of tuning. There are sockets for connection of an external aerial, extension speaker and external power supply.
The Beolit 1000 brings you external tonal quality. Audio output is 2.5 watts on the internal dry cells. Via a suitable mains converter the Beolit 1000 will deliver no less than 7.5 watts of audio output, making it ideally suited to use as a home radio set. It has individual bass and treble controls and gramophone and tape-recorder jacks.
You can use the Beolit 1000 in a car, with the specially designed lockable car-mounting bracket which operates on 6 or 12 volts and negative and positive earthing, and incorporates filters to suppress ignition interference. The bracket automatically cuts out the built-in power supply of the Beolit 1000 and cuts in the car battery, the car aerial and an extension speaker. When powered from the car battery the set will deliver 7.5 watts of audio output.
Available in teak, Brazilian rosewood and black goatskin finish. Dimensions: 201 mm high, 359 mm wide and 70 mm deep
In 1972 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. Beolit 1000 was one of those seven products.
In 1968 Beolit 1000 won the prestigious iF Design award.
“One of the best semi-professional fully transistorised hi-fi stereo tape recorders. It has professional data for speed, wow and flutter that meet international standards for studio tape recorders. New modern design concepts distinguish the Beocord 2000 de Luxe K from conventional tape reorders. Here are some of them: 4-track recording/2-track and 4-track playback; built-in 4-channel mixer section with twin faders for both mono and stereo recordings provides individual control and mixing of microphone, gramophone, radio and line signal inputs.
These faders make it possible to balance channels during recording. An aurally compensated twin fader makes it possible to balance playback volume levels, too. These features permit recordings of every kind, such as Multi-playback, or sound-on sound; that is, rerecording from one track to another whilst making another recording on the other track.
Synchro-playback – this feature consists of synchronising two recordings on separate tracks which you do wish to mix by recording, and may be used for language laboratory purposes and for automatic control of lantern slides. Echo – adding echo to both mono and stereo recordings. The amplifier equipment is an outstanding new system consisting of no less than seven fully transistorised easily replaceable amplifier units.
Monitoring: separate records and playback heads with individual amplifiers permit both before-the-tape and off-the-tape monitoring. Power output is 2 x 8 watts undistorted.
Recording level is indicated by two illuminated V.U. meters which indicate the sum of signals in each of the two tracks that can be recorded simultaneously.
Slack absorbers: Two smooth-running specially engineered slack absorbers take up slack, ensuring absolutely smooth starting and stopping at all tape speeds.
Electronic protection circuit prevents damage due to electrical overloads. No other tape recorder in this price bracket has these professional standards for electrical and mechanical specifications. Fine low-noise tape drive motor mounted on rugged non-torsion steel chassis. Four tape heads, 4-track recording but – a remarkable feature – the instrument plays back both 2-track and 4-track tapes.
The erase head (long-life dual-gap ferrite erases “right to the bottom” (70dB). The 2000 de Luxe permits recording from one tape recorder to another, parallel recording on a number of tape recorders, and simultaneous copying of both tracks. The Beocord may also be used as: public address system, permanently installed hi-fi control centre, and orchestra and guitar amplifier.” – taken from the 1967 – 1968 Bang & Olufsen product catalogue .
Beocord 1600 matched the Beomaster 1600 and Beogram 1600 both physically and technically. It combined high performance with easy, straightforward operation.
Ferric, chrome or metal tapes could be used. The Sendust tape head, Dolby B Noise Reduction circuits and Peak Programme Meter all contributed to high quality recording and playback. You could switch between all modes of play without fear of tangling the tape or damaging the mechanism.
This highly specified top-loading cassette deck closely matched Beomaster 2300 both in appearance and technical compatibility. But it was also worth serious consideration for use with any good hi-fi system, especially if ease-of-use was one of your demands.
Ferric, chrome and metal tapes could be used and the Dolby B noise reduction system kept your recordings clean and hiss-free. The large split-channel VU meters made it easy to set optimum recording levels using the input slider. The combined record/replay head was of long-life Sendust.
The 3-digit tape counter had a press-button reset; a memory function aided easy location of favourite tracks for repeat playing.
Piano-key controls separated all tape-transport functioned: these included a very precise pause control and a double-key record control – a safety check for preventing the accidental erasure of tapes.
Tape speed was highly accurate with deviation of less than +/- 1% and wow and flutter below +/- 0,15% DIN.
Beocord 2400 measured 40cm wide, 8cm high (11cm with cassette holder open) and 25cm deep. The slim cabinet was finished in either natural teak or rosewood.
At the 1969 Hanover Fair Bang & Olufsen and Jacob Jensen – designer of Beocord 2400 – were presented with the iF award for no less than 4 products for ‘outstanding industrial design’ including this sleek cassette recorder.
Beocord 1200 Type 4207 was a reel-to-reel tape recorder. Among its features it had sound-on-sound, automatic recording level control and mixing. The in-built PA amplifier could be operated without the motor running.
Beosystem 1200 – made up of Beomaster 1200, Beocord 1200 and Beogram 1200 was Bang & Olufsen’s B&O’s first designed system. 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 New York’s 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 tape 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.
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.
Beocenter 4000 was an elegant combination of an AM/FM stereo receiver (in effect the Beomaster 2200) and a high quality cassette deck whose performance levels matched those of more expensive separate decks. The Sendust tape head ensured the best possible playback and combined long life with optimum frequency response characteristics. There were two motors – one for fast wind, the other for normal play – so tape transport was smooth and stable at all times. A Dolby B Noise Reduction circuit ensured high quality, low-noise recordings. Despite its many technical refinements and comprehensive facilities, Beocenter 4000 was simple to operate.
Beocenter 4000, in which all parameters concentrate on the quality of radio and tape reproduction, was an unusual alternative to a disc system. The addition of a matching Beogram from the Bang & Olufsen range, plus two Beovox S45 bookshelf or P45 wall-mounting speakers converted it into the complete top-quality Beosystem 4000.
Beocenter 4000 comprised a 2 x 40 watts RMS amplifier, an FM, Long and Medium wave radio and a stereo cassette deck incorporating all the features you would expect to find only in separate high quality decks.
Beocenter 4600 was a multi-way combination unit incorporating a 2 x 25 watts RMS AM/FM receiver, an easy to use hi-fi cassette deck and an automatic record player. The lightweight arm had built-in bias compensation and carried Bang & Olufsen’s MMC 20S pickup cartridge with spherical diamond stylus.
The AM radio covered long and medium wavebands. Outstanding reception quality and high selectivity was secured by an Automatic Gain Control circuit, active noise suppression and hybrid filters.
The FM tuner was highly sensitive. Four stations could be pre-set for subsequent instant recall. The hi-fi cassette deck had all the features and qualities normally expected only in a separate deck:
* 3-digit counter with memory function
* electronic tape stop at end of play
* Dolby B Noise Reduction
* chrome or normal tapes could be used
The super Permalloy tape head was hard-wearing and had a long, useful lifetime. The record player too was automated: all functions were controlled by a single button. The anti-skating device worked automatically too. Bang & Olufsen’s MMC 20 S pickup cartridge with a spherical diamond was an integral part of this unit. Two Beovox S40 speakers complete this system if this was your choice.
In the 1960’s, small, transistorised radios became extremely popular. This was a result of miniaturisation of electronics products. The world leaders on the road to miniaturisation as we know it today, were the Japanese. Bang & Olufsen eager to come up with its own idea of making products smaller, designed its own transistorised radio: the Beolit 500.
An FM transistor set, entirely without dial, with push-button selection of up to five pre-tunable stations. The Beolit 500 has a large high-performance speaker, a telescopic FM whip, jacks for tape recorder, gramophone and extension speaker, automatic frequency control, and good battery economy. An attractive extra feature: the Beolit 500 can be used as an intercom system. Dimensions: 76 mm high, 264 mm wide, 191 mm deep. Choice of teak or Brazilian rosewood finish. Not available in the UK.
Beolit 500, type 1101 is one of those so-called ‘transistor radios’ – a small portable radio that could be carried around. However, Bang & Olufsen worked on the assumption that these small ‘portable’ radios were most often stationary. As well as an FM radio receiver, Beolit 500 could be used as an intercom via an extra loudspeaker (that it could also be adapted to receive police radio communications by short-circuiting a couple of switches was an entertaining, but unintentional side-effect).
Sockets for an external 7.5V power supply (via Beopower 600) and a tape recorder were fitted.
A thoroughgoing ‘black box’. Nothing in the shape of the device revealed how it worked or what it was. Only the inscription on the top of the unit told the user just how the black ‘magic mirror’ was brought to life so it could show which function has been activated. The unit was Bang & Olufsen’s first remote-controlled hi-fi system.
Beomaster 6000 History
Beomaster 6000 was the realisation of the Topline prototype on which work had progressed over the preceding years. The long flat cabinet of the Beomaster 1200 with its operation from the top and the depressed knobs was repeated. But the Beomaster 6000 is the first representative of a new phase in Jacob Jensen’s oeuvre. The slide rule motif symbolised mechanical precision, but now the entire idiom is adapted to the abstraction it was necessary to submit in communicating using electronics.
The visually, symbolically and tactilely easily understood slide rule operation belonged to the age of mechanisation and must be understood in extension of the modernistic machine aesthetics of the 1920s. The design of the Beomaster 6000 emphasises that it belongs to the electronic age and that it is part of the virtual, digital epoch. The volume is regulated stepwise by pressing one button to increase volume and another to reduce it. The buttons are gathered together in one large steel sheet, in which ‘tongues’ have been cut. These each have a play of less than half a millimetre as they are electronic micro-switches. The depressed adjustment knob, which made its first appearance in the General Electric radiogram study model around 1960, is an electronic tuner.
” The great quality of the slide rule motif was that it showed both the user’s input (setting) and the device’s output at the same time. The logical consequence of micro-electricity is a division of input and output – the electronics differ from mechanical operation in that their function is invisible. Jensen does what he can, nevertheless, to make it easy to understand what is happening. Input is placed in a silver-coloured control panel, while output (displays) is gathered under a sheet of dark glass. This magical black sheet, ‘the magic mirror’ that lights up while in use, is to give an extra experience over and above the purely aesthetical. The Beomaster 6000 is a very easy advanced quadraphonic radio. In view of the development team, four sound channels required your being able to adapt the sound to your position in the room. In this way, the first remote-controlled hi-fi system became a reality. ” – taken from ‘Jacob Jensen’ by Christain Holmsted Olesen.
Beomaster 6000 features
At the centre of the Beosystem 6000 was Beomaster 6000, a 4-channel amplifier with an FM tuner. Beomaster 6000 had a built-in SQ decoder (4-channel matrix) and was a full remote controlled system. Five FM stations could be pre-selected and there was manual tuning on the large illuminated FM scale. The FM tuner covered 87,5 – 104MHz. Tuning was carried out via feather-touch controls. The amplifier section was designed to cope with all sound reproduction systems: one, two or four channels. It produced 4×40 watts RMS (4 ohms) or 300 watts total music. 4-channel sound reproduction from records was popularly represented by two systems: CD4 discrete and SQ matrix.
CD4 (Compatible Discrete 4 channel) enabled high-quality sound reproduction with a high degree of separation between the four channels. CD4 was called at the time ‘TRUE 4 channel system’. However, many companies chose the SQ system because it was easily transmitted over FM and SQ records could be played on a high quality stereo record player. However, the price of convenience was less channel separation than the CD4 system afforded.
An SQ matrix decoder was incorporated in Beomaster 6000. Basically, its job was to reconstruct sound information for the two rear speakers. For CD4 records this reconstruction took place in the record-player, Beogram 6000.
Operation
Operation of Beomaster 6000 was child’s play. The large flat operation panel had logically grouped controls for all essential functions. Primary functions (e.g. programme source selection, volume, balance, bass and treble controls) were large, prominent, yet unobtrusive easy-touch buttons, while secondary functions (e.g. loudness, hi and low filters, etc) were smaller push buttons. Volume, balance, bass and treble controls were executed by a feather-touch of the finger tip. A servo-motor did the real work. An illuminated scale indicated position and control levels. There were facilities for frequency correction on all 4 channels. Each channel had a frequency range of 20-30,000 Hz. Distortion was lower than 0.1% at full power output.
Remote Control
The cordless (ultrasonic) remote control for the receiver could be bought as an accessory. This unit put you in true control of the music system. All the following functions could be controlled: volume, balance: left and right speakers; balance: front and rear speakers; five pre-selected FM stations; selection of external programme sources: record-player, tape/cassette-recorder; switching on and off (stand-by).
Connections
All necessary connection facilities were incorporated in Beomaster 6000: 4-channel record player, 2 or 4-channel tape-recorder. 4-channel headphones or two sets stereo headphones.
Beomaster 6000 was perfectly matched to partner the Beocord 5000 cassette recorder (introduced 1975). Beomaster 6000 was featured in an exhibition at New York’s MoMA (Museum of Modern Art) in 1975. At the time of its release it was the flagship of Bang & Olufsen’s hi-fi product range and was quite expensive to purchase. The UK price in 1978 was £581.50.
Accessories:
FM room aerial
An FM aerial type 8902010, was designed for use with Beomaster 6000 to be used in the home, within a certain radius of the radio transmitter. It was easily positioned at the rear of Beomaster 6000 and its two telescopic elements could be extended.
Design is a language which is understood by everyone…” as designer Jacob Jensen expressed it and demonstrated it in practice.”
A silicon-transistor high-fidelity amplifier with less than 0.6% distortion at all frequencies and at all volume levels up to 2 x 60 watts of power output. Its signal-to-noise ratio is better than 90dB (linear measurement). It has calibrated graphic controls and is extremely versatile, due to an unusual number of input and output facilities.
The Beolab 5000 is an amplifier that introduces no hiss or hum and reproduces all frequencies of the tonal range exactly as received. It has enormous power, permitting reproduction of even the loudest passages without distortion. Moreover, operation is logical and straightforward; varying or poor record quality can be compensated by means of efficient filters which remove the particular tonal range in which flaws are present; there is provision for connecting several speakers, including centre speaker, as well as provision for channelwise control of programme material. A special feature is a test control to facilitate adjustment of balance between channels. The use of silicon transistors ensures very low noise level, high temperature stability, and a very wide tonal range.” – taken from the 1967
Bang & Olufsen’s Beomaster 5000 FM tuner, BeoLab 5000 amplifier and Beovox 2500 Cube loudspeakers were the first product series designed by Jacob Jensen in 1967.
The traditional style for tuning knobs was replaced by an exact measuring instrument akin to the slide rule which was considered an innovation in changing the future of radios and amplifiers. The interface, in its precision and simplicity, proved to give the user optimal functionality. This solution had never been seen before and laid the foundation for the future form language of B&O. On this basis, Jacob Jensen was asked to design B&O´s audio programme. Beomaster 5000 was an FM tuner, with elimination of static between stations and a built in ‘data base’ which automatically tuned in on stereo broadcasts.
Partner to BeoLab 5000 was Beomaster 5000, an amplifier with the same slide rule interface.
The TV boom of the 1950’s hit the cinemas badly, which meant that the pressure on Bang & Olufsen’s sound engineers became less. The engineers’ love of high class sound reproduction, however, remained undiminished.
As early as the 1950s, they had developed stereo systems for the installation of Cinema-Scope systems in cinemas. In 1958, they were also responsible for the development of equipment for the first stereophonic radio transmissions from Denmark’s very first commercial radio station, Radio Mercur. When stereo started gaining ground, the engineers found new opportunities for a comeback.
The development of High Fidelity had already begun in the US and a number of small companies, headed by Scott and Fischer, had gained a dedicated following. By 1964, Bang & Olufsen was planning to conquer the new upcoming European Hi-fi market, a niche which ideally matched Bang & Olufsen’s survival strategy. Now engineers with more than 30 years’ experience behind them, under the leadership of chief engineer Nikolaj Krebs Sørensen, embarked on the development of the world’s most perfect hi-fi system, the BeoLab 5000 series.
With its ultra selective tuner and a powerful, distortion-free amplifier of no less than 2 x 60 watts, it offered qualities never seen before. The design was equally sensational. In the US, where the production of Hi-fi components had already started, they had found their form in the 19” rack format which was used by the first customers, the radio stations. When Hi-fi enthusiasts wanted quality tuners and amplifiers, they had to accept a design which belonged in the professional world.
Bang & Olufsen’s brief for the designers was: “Create a European Hi-fi format, which communicates power, precision and identity.”
This became designer Jacob Jensen and his assistant, David Lewis’ first assignment together for Bang & Olufsen. They solved it by designing the new linear controls like a slide rule bar in order to communicate the greatest possible precision. Thus began the era of the slide rule bar, a motif which was used and varied in the years to come.
The Hi-fi modules’ handles became countersunk Allen screws and the faceted and framed gold panels, which were the industry’s standard, were, in Bang & Olufsen’s design, transformed into extruded natural anodised aluminium.
BeoLab 5000 became a success, not only as Bang & Olufsen’s flagship, but also in more affordable versions, e.g.. Beomaster 1200 and 3000 and competitors were forced to follow suit. Elsewhere too, knobs were replaced by the linear slides – a development which continued until the mechanical grips were replaced by the electronic ‘easy touch’ controls of the Beomaster 1900.
At the 1967 spring fair in Hanover, B&O received the IF award for BeoLab 5000, Beomaster 5000 and Beovox 2500 Cube for outstanding and user friendly design.
