Beomaster 5000 was one of the components of the first ‘true’ Hi-fidelity units that Bang & Olufsen ever created. Designed by the pen of Jacob Jensen, the Beolab 5000 System - made up of two main components: the Beolab 5000 amplifier and the Beomaster 5000 tuner - was, from the outset, an object for pure audiophiles and broadcasters alike.
With the emphasis on quality, each Beomaster 5000, before it was shipped from the factory in Struer, was rigorously checked to ensure that it matched the exacting specifications that had been designed for it. A test report was provided for the prospective purchaser as proof.
As a tuner designed for partnering with Beolab 5000, the unit was extremely sensitive and covered the FM waveband only. Included was AFC and automatic mono/stereo swiching. It also cut out annoying static or ‘white noise’ which was all-so prevalant while tuning in radio stations and stereo reception was automatically cut where signal strength was weak. Tuning was by way of Jacob Jensen’s innovative ’slide rule’ system, replacing normal knobs and switches.
Its usability was well covered with both DIN and RCA sockets on its rear for amplifier connection. It could also be connected to a reel-to-reel tape recorder.
An item of desirability, even to this day, Beomaster 5000 was ideally suited to the Beolab 5000 amplifier together with the Beogram 1800 record deck, Beocord 2400 tape recorder, Beovox 5000 loudspeakers together with Beovox 2500 Cube speakers for enhanced treble response.
Bang & Olufsen, together with Jacob Jensen, won the iF Design Award held at the 1967 Spring Fair in Hanover, for Beomaster 5000, BeoLab 5000 and Beovox 2500 Cube for outstanding and user-friendly design.
