BeoGram CD4500

BeoGram Compact Disk Players

Production: 1989 - 02/1994

Designer: Jacob Jensen David Lewis

Documents: Service Manual, Owners Manual

A beautiful-looking slim lined CD player which matched perfectly the rest of the Beosystem 4500. The unit was equally at home on a shelf as hung up on the wall where the whole ensemble looked like a piece of modern art.

It was the finish of the CD cover which differentiated between itself and its predecessor, the Beogram CD3500, in that the 4500 was highly polished against the dull grey livery that the Beogram CD3500 possessed. Technically they were identical.

The Beogram CD4500 was produced for use with Beosystem’s components when it could be controlled remotely.  Without Beomaster 4500 the CD player was very basic indeed.
