Beogram 1500 combined ease of operation and advanced technology in a simple, straightforward way. All its operations were controlled via a single button.
Another advantage of this totally integrated design was its immunity to external shock and vibrations. The electronic servo drive system ensured correct turntable speed at all times. The low-mass arm had built-in bias compensation, and the MMC 20S pickup tracked at only 1,5 grams.
The unique pendulum spring suspension helped make the Beogram range of record players immune to the external shock and vibrations which would cause most other record decks to mistrack and damage the record groove.
Beogram 1500 could be made up as part of the Beosystem 1500, when linked together with other compatible Bang & Olufsen products.
This deck was the basic model of its time but the inherent design of this deck meant that the performance was extremely similar to the top of the range radial decks. Very easy to set up and simple to use, a true bargain buy in later years.
Beocord 1900 equalled Bang & Olufsen’s top-of-the-line cassette deck (Beocord 5000) in terms of specifications and performance, but it but it did not have the same wide range of facilities and operational refinements.
This does not mean that the Beocord 1900 was difficult to operate. On the contrary, the slanting front panel which contained all the operational facilities made the set’s controls handy and easily accessible. The cassette eject mechanism was air damped so that delivery was gentle and controlled. Two large VU meters enabled accurate setting of recording levels.
The microphones socket was placed discreetly under a sliding panel together with a balance control which enabled signal level adjustment in both channels. All the features which characterised high quality and high performance levels in cassette decks were incorporated. These included a combined recording/play-back Sendust tape head and Dolby B Noise Reduction circuits.
Beocord 1900 used precision techniques that ensured stable tape drive and the highest standards of recording and playback. Yet despite its comprehensive facilities it was easy to use and harmonised comfortably with many different Beosystems.
Beocord 1900 could be made up as part of the Beosystem 1900 or Beosystem2400, when linked together with other compatible Bang & Olufsen products.
Top of the range monitor speaker, these were much more like the Beovox S60 than the Beovox M75 that replaced them.
They were 4 way speakers with the tweeter and midrange level with each other and the Phase link and woofer below. They could be fitted with the dramatic trumpet stand and were the speakers specified for the Beosystem 6000.
Beovox Uni-Phase M100 and M75 were the top models in the 1979 – 1980 range of Bang & Olufsen speakers.
They reproduced sound with studio monitor quality, which, in practice meant that even at very high sound pressure levels (volume) they reproduced sound with constantly neutral, linear phase quality. They could also withstand hard-working conditions similar to those met in sound studios, because they were effectively protected against damage from overloading. Their power-handling capacities were specified at 100 and 75 watts RMS respectively; however, their unique overload protection circuits permitted them to handle music passages above these rated capacities.
Special emphasis was placed on Beovox M100’s ability to reproduce clean, powerful bass. That it why it was given a ported bass-reflex cabinet with a 30,5cm woofer. The cabinet’s volume was 89 litres. Bass response went down to 27Hz (measured at +/- 4 – 8 dB).
Beovox M75 had outstanding overall performance too, and was equally suitable for medium-sized or larger rooms. Both models had specially-designed pedestals which could be adjusted to the correct listening height and angle.

Beovox Uni-Phase P30 loudspeaker handled up to 30 watts RMS power and reproduced sound with neutral, linear phase quality.
They were panel speakers designed to be hung on the wall and are therefore ideal for rooms where space was limited. Only 9cm deep, its volume was 12,9 litres. Fitted with a 16cm woofer and a 2,5cm tweeter. Frequency range 49 – 20000Hz.
The Beovox P30 were effectively a wall mounted S30. They appeared very thin though were in fact slightly deeper than one thought as the resin back protruded a fair bit at the back. Sound quality mirrored that of the S30 with generally good quality sound though they are bass light and must be wall mounted to achieve their best.
Beovox Uni-Phase P45 loudspeaker was a revised version of the Beovox P50 and was a high fidelity panel speaker for wall-mounting.
Weighing only 8kg the P45 had a net volume of 25 litres. Frequency range was 40 – 20 000 Hz with less than 1% harmonic distortion. There were two 12,5cm woofers, a special 8cm Phase Link unit and a 2,5cm dome tweeter.

When B&O’s engineers had discovered that the signals from respectively the bass unit and the tweeter in a loudspeaker do not reach the human ear at the same time, and that as a consequence a very slight distortion occurs, they asked Jacob Jensen to design a loudspeaker cabinet in which the units were skewed in relation to each other.
Jensen illustrated B&O’s technical discovery with an angle: “form follows function”. B&O’s loudspeakers in this way achieved a characteristic visual identity in the 1970s and 1980s.” – taken from ‘Jacob Jensen’ by Christain Holmsted Olesen.
Although the speaker was the tallest in the original line-up of aluminium compact passive speakers, Beovox C75 was no taller than an LP record, yet its reproduction quality equalled some of the full-size Beovox models. The one-piece aluminium log-line casing and separate bass (2 x 10cm bass drivers) and treble drivers (1 x 2,5cm) were specially designed to sound best in small rooms. Power handling was 75 watts RMS. Both the C75 and their smaller counterpart, the C40, benefited from the advantages of the “log line transmission system” and exploited the acoustic properties of small rooms to ensure well-balanced sound reproduction quality from these physically small cabinets.
As part of the Beovox Uni-Phase family, they also had linear phase and linear amplitude characteristics, which meant that they reproduced all types of music naturally. The range of C-type speakers won the ID Award in 1978.
Beovox C75 was eventually replaced by the CX100 in 1984.
Beovox C30 and C40 speakers were two compact bookshelf units offering high performance from deceptively small cabinets. The 10cm woofer and 2,5cm tweeter were mounted in thick aluminium casings to eliminate audible resonance. Log-line transmission ensured wide frequency response and clean, clear sound. Ideal for smaller rooms, their power handling capabilities were 30 watts and 40 watts RMS respectively.
