BeoCenter 9000


Production: 1986 - 01/1990

Documents: Owners Manual

A new generation of music centres was developed with the arrival of Beocenter 9000 which greatly influenced the whole range of Bang & Olufsen products from the first day that it was introduced. By the mid-1980s when Beocenter 9000 was available to purchase, the use of compact discs had really taken over people’s choice of preferred medium when it came to music. A compact disc player therefore was one of three sources available to the user, the other two being a good-quality FM/AM radio and an HX-Pro equipped cassette deck. It was only a turntable which was omitted. That - by way of a separate free-standing deck - could be purchased separately. Suggestions here were Beogram 3000 or (the later introduced) Beogram 9000.

The first thing that struck the user - apart from the low, good-looking brushed aluminium panels on the top - were the two bands of black glass.  The lower band comprised a sensi-touch panel which was used for volume, source, radio stations and the like. Just a touch of the finger meant that the operation sprung to life instantaneously. This had been seen before on the Beomaster 2400 and Beogram CDX of course, but linked to this ease of operation was the way that both the CD and cassette comprtments slid silently across to reveal the housings for their respective media.  Time has proved the system was excellently designed and constructed, with few mechanical breakdowns occurring over the years. It was a triumph of engineering and the whole range of Beocenters which envelop this technology has remained highly popular since its inception.

Although many of the parts were ‘borrowed’ from other models in the range (the CD player and amplifier were based upon those of Beosystem 3300) a lot of the ideas were new… or at least they looked new. High specifications were in evidence with this model and the user was never short of things that he or she could do with it, from programming to listening in other rooms. Remote control was useful when either the A Terminal or the AV Terminal (followed a couple of years later by Beolink 1000) could be used. It was suggested at the time that either the Beolab Penta speakers could be used else any of the larger Redline speakers (such as the RL60) be used.

Beocenter 9000 was superceded by Beocenter 9500.

System stand ST9500 was produced especially for accommodating the Beocenter 9000 although was equally at home with any of this particular system’s sister products such as the Beocenter 9500, 8000 and 8500.
