Bang & Olufsen Jacob Jensen - Beomaster 5000 - Control Panel Stereo set

An electronically synthesized tuner with automatic fine-tuning and a two-stage manual drive contributed to fast, precise placement of radio programs and excellent reception quality. Nine station frequencies (for each combination of wavebands) could be stored in the Beomaster’s microcomputer memory to ensure immediate retrieval.

The distortion-free stereo amplifier featured a very advanced function unique to Bang & Olufsen: Automatic Power Handling Control. This special circuit continuously monitored the dynamic range and the power of the signal and instructed the microcomputer to reduce the volume if the combined effects of these two parameters threatened clipping or damage to the speakers. This kind of overload had become more common since the introduction of the Compact Disc, which can produce signals with enormous dynamic range, but it could not occur on the Beomaster 5000.

An internal, variable-speed fan ensured proper heat dissipation, even when the Beomaster was used in stack mode. The direct operation of all main functions was available on the Beomaster itself if the Master Control Panel was not available. These controls were located under a fold-down cover that opened with a touch.

Beomaster 5000 had no visible controls. Normal operation was via the Master Control Panel – a slim, desk-friendly keyboard that provided access from the chair to all functions, including microcomputer programming and storage, timer functions, status monitoring, day and time display, volume, tone and stereo balance settings, and the control of all sound sources. A program sequence function allowed you to plan an entire listening evening in advance, consisting of vinyl, radio and cassette music in any order and combination. Once set, this “command performance” played continuously as instructed without further use of the controls.

I have indicated the condition as good. However, please form your own opinion by closely inspecting the pictures. The devices are over 40 years old and show some signs of use.

WARNING: The Master Control Panel has three displays; on the left display there are pixel defects (see also the photos).

Technically, both devices are in order and all commands can be executed via the panel.
