Documents: Schematic, Service Manual

As another product based upon the Beomaster 1100, Beocenter 1800 met DIN 45500 hi-fi standards by a sizeable degree. Offering 2 x 22 W of good-quality sound with minimal distortion, the first thing one noticed was the turntable on top of the machine. This automatic record deck could play both 33 and 45 RPM records as standard with an MMC 3000 cartridge being fitted. The ease of an automatic record deck meant that the user just put on a record, pressed ‘play’ and the machine did the rest! A special spring mechanism ensured that the unit was free from vibrations and external shocks.

The unit was certainly space-saving, but if cassette tapes were required then the Beocord 1100 unit was the player recommended.

Again, radio reception was of high quality, with AFC holding FM stations steadily for you while you listened. There were the necessaryconnections for a pair of headphones, a cassette recorder and two sets of stereo speakers.

When connected to a pair of suitable Beovox Uni-Phase passive loudspeakers, it was known as Beosystem 1800.
