Very nice beocenter 4000, with the high quality double driven double motorised HX Pro & Dolby B cassettedeck. 2x40 w amplifier and fm/am tuner The B&O double cassette deck was a properly engineered piece of work, however, and used two totally independent cassette decks. Whist the playback-only deck was much the same as the one used in the Beocenter 2200 (and thus the rest of the more recent Beocord models in the range at the time), the recording deck introduced yet another new feature: auto reverse. This would soon become standard for all B&O cassette recorders, but the Beocenter 4000’s recording deck was the first. Not content with this, the designers also included the HX Pro headroom extension circuit in the recording deck, something that was not even fitted to the more expensive Beocenter 7700 or Beocord 2000. Minor insignificant signs of use
