BeoMaster 1200

BeoMaster Tuner/Amplifier

Production: 1969 - 12/1973

Designer: Jacob Jensen

As heart and brain to the Beosystem 1200 - Bang & Olufsen’s first complete ‘designer’ stereo system - Beomaster 1200 was considered in the late 1960s when the very idea of possessing a matching hi-fi system hadn’t been thought of.  Up to that time, customers bought everything that they needed on a ‘pick and mixed’ basis.  It was not until Beosystem 1200 was announced that people could even contemplate buying similarly-looking music systems, and not just the way that they looked on the outside as the technology within was complimentary too ensuring that all components were ‘plug and play.’

And what were customers buying in these early days? Cassette decks were on the market of course, but unfortunately for the Bang & Olufsen customer, no cassette recorder featured yet in their product range. So it was a choice of record deck or reel-to-reel tape deck which were the only available sound sources. The other feature was that of FM radio which had already been integrated into the Beomaster 1200 electronics.
