Beocenter 4000 was an elegant combination of an AM/FM stereo receiver (in effect the Beomaster 2200) and a high quality cassette deck whose performance levels matched those of more expensive separate decks. The Sendust tape head ensured the best possible playback and combined long life with optimum frequency response characteristics. There were two motors – one for fast wind, the other for normal play – so tape transport was smooth and stable at all times. A Dolby B Noise Reduction circuit ensured high quality, low-noise recordings. Despite its many technical refinements and comprehensive facilities, Beocenter 4000 was simple to operate.

Beocenter 4000, in which all parameters concentrate on the quality of radio and tape reproduction, was an unusual alternative to a disc system. The addition of a matching Beogram from the Bang & Olufsen range, plus two Beovox S45 bookshelf or P45 wall-mounting speakers converted it into the complete top-quality Beosystem 4000.

Beocenter 4000 comprised a 2 x 40 watts RMS amplifier, an FM, Long and Medium wave radio and a stereo cassette deck incorporating all the features you would expect to find only in separate high quality decks.
