Beogram 4002, was a tangential record deck which could play records at either 33 rpm or 45 rpm. The turntable was a replacement for the remarkable and ground-breaking Beogram 4000. Complementing Beomaster 6000 and Beocord 50oo with its keys manufactured from strips of brushed steel, there were few other noticeable changes externally although the internals had a new DC servo fitted and the whole technology of the machine was simplified somewhat. It was fitted with the MMC 4000 cartridge and retainned its simplicity of use and good looks.

What was important with this record deck however, was the fact that it was the first of its kind which could be linked directly to a suitable Beomaster via a 7-pin DIN plug. The system was known as Datalink and Beogram 4002 was the first product to be fitted with the necessary hardware and software in order to achieve this. This allowed start and stop play of the machine as well as other functions which otherwise had been previously controlled by a user effecting a control on the record deck itself.  The two extra pins allowed digital information to be transferred between both record deck and Beomaster so that each machine could ‘talk to each other’ in order to inform each other just what operation each component was undertaking.  The idea led to the advent of the Datalink system which really came into its own with the introduction of the follow-up turntable, the Beogram 4004.

When connected to the Beomaster 6000 and suitable loudspeakers, the whole system was known as Beosystem 6000.

A whole host of awards was given to the record deck including the Italian Gold Sim in 1974. The Beogram 4002 was included within New York’s Museum of Modern Art (MoMA) Design Collection in 1978.
