BeoCenter 7700

Bang & Olufsen BeoCenter 7700

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.

BeoVox S75

Bang & Olufsen Beovox S75

The S75 was a four way speaker designed for stand mounting and was a suitable match for any of the receivers offered at the time. It could be regarded as the bigger brother of the fabled S45.2 and replaced the very similar S60 in the speaker range.

The cross over was changed along with a redesign of the cabinet. The result was a speaker with more bass emphasis than the S60 but still with a soaring top end. Criticism could be levelled that the bass was at times slightly overblown, but for rock music, it hit the spot.

The extra size also emphasised the cabinet makers’ skill with the rosewood model in particular often showing a wonderful selection of flame veneer.

Although these speakers lack the accuracy of the S45.2, many will find the extra bass an attraction and will choose these in front of their fabled brother.

Beovox Uni-Phase S75

Pressure chamber speaker with linear phase sound reproduction and wide frequency range: 36 – 20000 Hz. Was suitable for placement in a shelving system but also available with aluminium pedestal for those who prefer a free-standing model. Speaker units included a 25cm woofer, a special 12,5cm Phase Link unit, a 5cm mid-range dome and a 2,5 dome tweeter. Volume was 40 litres; weight 11kg

BeoCenter 3300

Bang & Olufsen BeoCenter 3300

Beocenter 3300 combined a powerful AM/FM stereo receiver with an automatic record player. Technically identical to the Beomaster 2200, the receiver section offered programmes on FM, long and medium wavebands and up to 2 x 40 watts RMS amplification with low distortion levels. It also had the same logical operation facilities.

The record player had a spring-suspended rotatory mechanism and an electronic servo drive system which ensured accurate turntable speed – even during variations in the mains current supplies. A special pendulum leaf spring suspension made the arm and platter immune to external shock and vibration which causes most other record players to mistrack and damage the record and sometimes even the stylus.

All functions of the record player were operated by touching a single button. The start/play/stop cycle is entirely automatic and moves, lifts or lowers the arm much more delicately than could the human hand. The MMC 20E cartridge carried an elliptical diamond stylus.

Beocenter 3300 had sockets for a tape deck, an extra record player, headphones and two sets of stereo speakers. The unit could be made up as part of the Beosystem 3300, when linked together with other compatible Bang & Olufsen products.

BeoCenter 2600

Bang & Olufsen BeoCenter 2600

Beocenter 2600 consisted of a 2 x 25 watts RMS AM/FM receiver and a hi-fi cassette deck. The radio section covered Long, Medium and FM wavebands. A red/green LED indicator made recording easy and accurate, whether your sound source was the radio or a microphone (not supplied) connected to the hidden socket. A separate record player could be added if required.

For the cassette section, you could use both ferric and chrome tapes. The Dolby B Noise Reduction circuits ensured clean, noise-free recordings every time and the Super-Permalloy tape head was hard wearing with a long service life.
