BeoCord 2000K

BeoCord Reel to Reel

Production: 1964 - 1965

Designer:

Beocord 2000K was a stereo tape recorder, offering three speeds and was of the 2-or 4-track format. It was technically improved from the Beocord Stereomaster 610T. It delivered 2×8 watts of music power and could be used as either a three-speed 2- or 4-track machine.

Similar to Beocord Stereomaster 610 the machine had several technical advancements using transistors to replace many of the former components. As strange as these advancements seem to us nowadays, they were significant at the time in the usefulness and effectiveness of these big, bulky and heavy machines. One such improvement was by the use of special silver foil which was inserted at the ends of the reels of tapes which were recognized when they passed through the heads, causing the machine to halt. A little primitive now, but simple and effective.

Beocord 2000K was replaced by Beocord 2000K de Luxe.
