BeoVision 3500

Beovision 3500 type number: 3907 was a 56cm colour television designed by David Lewis and Henning Moldenhawer. It could be placed on two types of stand – the trumpet stand (shown above) and the cross foot stand.

By 1975, colour television had become commonplace in homes throughout Western Europe. And a lot of those homes were furnished in white – the ‘in’ colour of the 1970s. Television, as a lot of home furnishings, followed this trend and Beovision 3500, with its trumpet base and cross-base on wheels, reflected what was happening in the world of interior design. The cabinet was made of moulded plastic and its appearance was markedly different from most other televisions of the era.

Beovision 3500 was Bang & Olufsen’s first fully transistorised television; this meant that very little warm up time was necessary for picture and sound. The choice of television channels had increased considerably over the previous years and the controls were adapted accordingly. “In everyday use, you select your TV programmes using the easy-touch push buttons at the top. Each of these can be set to one TV channel; this is done once only using the scaled potentiometer dials. These eight dials are only visible when the panel is opened; this is where you or your dealer can set the VHF and UHF channels that you are able to receive. Beovision 3500 has automatic frequency control, AFC, which locks the TV stations once they have been selected.” said the sales literature in 1975.

With Beovision 3500 it was clear that an icon had been created. The cabinet was made of moulded plastic and its appearance was markedly different from most other televisions of the time. However, the wooden cabinet was retained in the similarly-styled Beovision 3600 model. From 1975, Bang & Olufsen was also able to equip all its televisions with Automatic Cut-off Control.

An invention by the young engineer Erik Albert Jensen made waves internationally in the television sector. Cut-off Control ensures that the colour balance is maintained throughout the service life of the television. No fewer than 50 times each second the three electron beams are measured and corrected independently, thus avoiding any annoying deviations in colour.

BeoVision 3602

Like other Bang & Olufsen colour TVs, Beovision 3602 had the automatic cut-off regulating circuit which ensured natural colours throughout the set’s useful lifetime. The in-line picture tube allowed for easier and better convergence in order to avoid the usual discoloured edges – not least when viewing a black & white transmission.

Internally the Beovision 3602 was identical to the Beovision 3502 so one obtained the same outstanding picture quality and equally good sound reproduction from the large, forward-facing loudspeaker.

On the easy-touch panel one could select programmes and turn on the set in the same action. Regulators that are not used often are hidden in tow touch-release compartments – one for sound and one for video adjustments. Power consumption was exceedingly low – only 110 watts and the low heat generation made this set suitable for placing in a shelving unit.

BeoVision 3702

BeoVision 3702

Beovision 3702 was a 56cm colour TV with small outer dimensions, a highly advanced construction throughout and the most logical operation facilities then on the market.

The ultrasonic remote control was designed to be operated with one hand and its most important regulators could be ‘read’ by the finger tips. These regulators – for brightness, colour saturation and sound are set in relief, so there was no need to look. The user could feel which position was which by the tactile buttons.

Any of eight pre-set stations could be called, and, by pressing the special reset facility, all adjustment levels including sound, would revert to their predetermined basic levels.

Beovision 3702 could be switched off at the main ‘off button on the set’s simple operation panel. Or one could switch it off with the remote control module in which case, the set goes into stand-by position. By pressing one of the programme selectors there is a picture on-screen within 5 seconds together with sound. The picture tube was of the in-line type which needed fewer adjustments and consumed less power – only 115 watts.

The chassis was modular and there was an automatic cut-off regulating circuit to maintain long-term colour purity. Beovision 3702 could accommodate a VCR without further technical adjustment and could be fitted with a special optional kit to reproduce sound through a hi-fi system. Two pre-stamped blanks on the set’s fascia allowed for the insertion of a headphone or extension speaker terminal and switch.

BeoVision 3800

Beovision 3800 and 3900 were 22″ colour TV receivers finished in genuine wood veneers (teak or rosewood). They superceded models 3602 and 3702 in 1979. The sets were slim and elegant and their classic design suited any home décor according to the 1979 – 80 catalogue. High Bright picture tubes allowed for satisfactory daylight viewing since they permitted around 70% more light than from the screen than conventional picture tubes.

Beovision 3800 was for direct (set box) operation while Beovision 3900 permitted you to operate the set via an ultrasonic remote control handset. Beovision 3900 could also be supplied equipped for Teletext reception.

Automatic cut-off circuits guaranteed correct balance between the three basic colours (red, green blue) even after a long period of use. In fact, these sets incorporated every refinement which still makes Bang & Olufsen’s television sets among the market’s best. VCR programmes could be played without additional technical adjustment. There was an automatic synchronisation on all channels.

A choice of two mobile undercarriages were available. A tall undercarriage (42cm high, type 3057) depicted here, and a lower one (34cm, type 3058). Both were sold as optional accessories

BeoMaster 1400 M/K

Bang & Olufsen BeoMaster 1400 M_K

BeoMaster 1400 M/K

“A splendid example of engineering and up-to-the-minute design, this all-transistor high-fidelity mains radio was developed by B&O for the ever-increasing number of listeners who want a radio which “has everything”

Its excellent FM section has five push-buttons. One is the usual FM bandswitch button; each of the other four can be individually tuned and locked to any station in the FM band, permitting you to tune in your favourite programmes at the touch of a button.

The Beomaster 1400K meets the wishes of the many listeners who insist on superb tonal quality and interference-free low-noise reception of stations outside the FM band. The razor-sharp selectivity of the Beomaster 1400K is a product of its numerous intermediate-frequency circuits. A further feature is a built-in short-wave expander for the SWII band, permitting you to ‘spread’ stations for maximum ease of tuning. There is a built-in decoder for reception of stereo broadcasts.

The amplifier of the Beomaster 1400K has very low distortion (less than 1%) at all frequencies and at all power output levels up to 2 x 15 watts. Its volume control circuit is physiologically compensated in the bass and treble ranges at low volume levels. A highly efficient balance control permits complete suppression of either channel at will.

The Beomaster 1400K has two built-in pressure chamber speakers and jacks for two pairs of external speakers, switchable from the front panel. The gramophone input circuit incorporates a pre-amplifier which is easily replaceable to permit use of stereo record players both with and without pre-amplifiers. A tape recorder jack is also provided. Despite the vast amount of circuitry, cabinet dimensions are relatively small.

Dimensions: 112mm high, 744mm wide, 252mm deep. Choice of teak or Brazilian rosewood finish.

The set is identical with the Beomaster 1400K and has no built-in speakers.

Dimensions: 12mm high, 414 wide, 252mm deep. Choice of teak or Brazilian rosewood finish.”

BeoMaster 900M

Bang & Olufsen BeoMaster 900

BeoMaster 900M

The inspiration for the Beomaster 900 came from the brains of Henning Moldenhawer.

The first product of the new era was launched in 1964.

Beomaster 900 was a fully transistorised radio with FM stereo radio. It was even launched in a version with two built-in speakers – Beomaster 900K – making it clear to everyone that it contained two independent stereo loudspeakers. Bang & Olufsen wanted to design a product so unique that it would open the doors to distribution throughout Europe, in the same way as the “Five Lamper” had done in Denmark 30 years earlier .

Beomaster 900M

This version of the Beomaster 900 was developed specially for those who require a set for use with external speakers. Otherwise, the Beomaster 900M is identical with the Beomaster 900K. Dimensions: 146mm high, 404mm wide, 230mm deep. Choice of teak or Brazilian rosewood finish.” – taken form the Bang & Olufsen product catalogue 1967 – 68

The most remarkable aspect, however, was not in the technology, but in the design. Transistors, which are small compared to radio tubes, generate less heat. As they require less space to release heat, transistors allow for radically different cabinet designs. The architect and designer, Henning Moldenhawer, knew how to exploit this. He designed the world’s first low, flat radio cabinet, creating a radical innovation in the process. From practically one day to the next, the good old tube equipped radio had become obsolete. Now it was transistors, not tubes, which for the first time would be powered from the mains. While the sound was improved, the loudspeakers also underwent significant changes, becoming more compact. After all, in those days, loudspeakers were foreign elements in the living-room. This was achieved with the pressure chamber loud speaker which reproduced sound of a quality which had, until then, only been possible with far bigger boxes. A long, low and fully transistorised mains radio, which played immediately – with no warm-up necessary, as was the case with the radio tubes – was an achievement in itself. In addition, the design concept challenged all established ideas for radio design. The new Beomaster 900 marked a revolution. It was the architect Henning Moldenhawer who, for the first time in the history of radio, extended the front all the way out to the sides of the unit, breaking with the traditional framing of the front which all radios, TVs and loudspeakers had been using until then. This motif was retraced in Bang & Olufsen’s future design language. It was even repeated graphically in the company’s advertisements. Beomaster 900 became a European-wide success. At the same time – and much to the company’s surprise – its share of the Danish market did not fall. On the contrary, it rose significantly – at a time when the last of the remaining Danish manufacturers went to the wall. Proof indeed that design is not only for connoisseurs, but is a universal language, at least when applied with talent and as an expression of the product’s conceptual content, i.e. making the product itself a communicator. When, some years later, Bang & Olufsen explained its identity, this visually self-communicating aspect was dubbed ‘Autovisuality’. Concept communication in terms of what the unit is and can do, communication between the unit and the user, but also identity communication between those who create the products and those who select and acquire them as well as between those who own the products. ” Beomaster 900K: This all-transistor mains-powered stereo radio will revolutionise your ideas about radio and was awarded the iF prize at the International Hanover Fair. The Beomaster 900K is an all-transistor mains-powered stereo radio featuring a specially engineered highly-efficient dual-channel audio amplifier for reproduction of stereo gramophone records (delivers 2 x 5 watts of undistorted power output). It is prepared for single transmitter stereo broadcasts, having a B&O multiplex adaptor (stereo decoder). A Beo-Beacon pilot lamp lights up when the receiver is tuned to a station transmitting an FM stereo programme or when the receiver is switched to play stereo gramophone records or stereo tapes. The Beomaster 900K has two B&O pressure-chamber speakers. Dimensions: 146mm high, 744mm wide, 230mm deep)
