At the time of Beogram 3400’s release, there was substantial interest in ’surround sound’ from black vinyl records using the various forms of quadraphonic systems that were around at the time. A fad, perhaps… a little like 3D cinema, which rears its head every now and again only to hide back in a cupboard a few years later. However, if a customer wished to foray into the world of quadraphonic, then the Beogram 3400 would have been a good choice as this particular record deck was able to play both stereophonic as well as SQ-matrix quadraphonic recordings. The possibility of playing CD4 records was also an option. For this, a supplementary CD4 decoder (the CD4 Demodulator) could be bought which automatically detected and played back CD4 records when setting up with the turntable.
Beogram 3400 had a radial turntable which played back discs at both 33 and 45 rpm. It came with an MMC 5000 cartridge and matched well other Bang & Olufsen record decks of its day with its sleek good looks, choice of finish and automatic playback.
An exciting record deck for the Bang & Olufsen collector.
