BeoCord 1900

Bang & Olufsen BeoCord 1900

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.

Beovox M70

Bang & Olufsen Beovox M70

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 M75

Bang & Olufsen BeoVox M75

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 P30

Bang & Olufsen Beovox P30

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 P45

Bang & Olufsen Beovox P45

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.

BeoCord 5000 (1975)

Bang & Olufsen BeoCord 5000 1975

Beocord 5000 was a superior cassette deck with a Sendust tape head, dual capstans and a special servo drive system which secured low wow and flutter-data. Electronic recording level indicators (Peak Programme Meters) and the Fade in/Fade out functions facilitated exceptional recordings of the most demanding types of music. An automatic demagnetizing device helped ensure optimum signal/noise ratio at all times.

A Hall generator secured the most reliable automatic stop at the end of play. Because it worked electronically it was superior to mechanical systems which are always subject to wear and tear, stress and strain. Naturally Beocord 5000 incorporated Dolby B Noise Reduction circuits. You could also switch from fast forward to fast rewind, or normal play, without endangering your tapes or damaging the drive mechanism.

Despite these technological refinements Bang & Olufsen still didn’t forget the greatest advantage of the compact cassette – that of convenience. That’s why Beocord 5000 was so easy to use. The logically-arranged easy-touch buttons were clearly marked to aid simple, problem-free operation. An illuminated read-out panel told you the operational status of the deck at all times. The display could be read through the black Perspex cover which protected the cassette housing against dust. The unit had two peak programme meters which reacted faster than conventional VU meters in registering recording level and thus ensuring optimum recording quality.

There were two main design models in the Beocord 5000 range:the three head type 4705 was replaced in 1977 with the twin head 4715/4716 models.

What you need to know is that these were the only cassette deck with a B&O designed mechanism. It was designed to be to cassette decks what the Beogram 4000 was to record players. From a technical point of view, it was way ahead of its time.

However it was stupendously complicated and this hit reliability hard. The three head version hardly ever worked fully and the later two head was only a little better. Gorgeous to look at and packed with features, it will break your heart! B&O replaced this with the Beocord 8000, which had a bought in tape transport….

BeoVox 1001

Bang & Olufsen BeoVox 1001

The Beovox 1001 was a very similar loudspeaker to the Beovox 1200 (Beosystem 1200 version), but to match the new black finish of the Beomaster 1001 the metal grille was made black.

Sadly, the designers did not take the opportunity to fit a dome tweeter (as fitted to every other Beovox loudspeaker of the period), so the original (and outmoded) 2.5” cone type remained. As the Beomaster 1001 offered the facility of Ambiophonic stereo, 4 Beovox 1001s could be connected, and the model was also suggested for use with the Beogram 1500-1 record player.

BeoCenter 4600

Bang & Olufsen BeoCenter 4600

Beocenter 4600 was a multi-way combination unit incorporating a 2 x 25 watts RMS AM/FM receiver, an easy to use hi-fi cassette deck and an automatic record player. The lightweight arm had built-in bias compensation and carried Bang & Olufsen’s MMC 20S pickup cartridge with spherical diamond stylus.

The AM radio covered long and medium wavebands. Outstanding reception quality and high selectivity was secured by an Automatic Gain Control circuit, active noise suppression and hybrid filters.

The FM tuner was highly sensitive. Four stations could be pre-set for subsequent instant recall. The hi-fi cassette deck had all the features and qualities normally expected only in a separate deck:

* 3-digit counter with memory function

* electronic tape stop at end of play

* Dolby B Noise Reduction

* chrome or normal tapes could be used

The super Permalloy tape head was hard-wearing and had a long, useful lifetime. The record player too was automated: all functions were controlled by a single button. The anti-skating device worked automatically too. Bang & Olufsen’s MMC 20 S pickup cartridge with a spherical diamond was an integral part of this unit. Two Beovox S40 speakers complete this system if this was your choice.

BeoVox S75

Bang & Olufsen Beovox S75

The S75 was a four way speaker designed for stand mounting and was a suitable match for any of the receivers offered at the time. It could be regarded as the bigger brother of the fabled S45.2 and replaced the very similar S60 in the speaker range.

The cross over was changed along with a redesign of the cabinet. The result was a speaker with more bass emphasis than the S60 but still with a soaring top end. Criticism could be levelled that the bass was at times slightly overblown, but for rock music, it hit the spot.

The extra size also emphasised the cabinet makers’ skill with the rosewood model in particular often showing a wonderful selection of flame veneer.

Although these speakers lack the accuracy of the S45.2, many will find the extra bass an attraction and will choose these in front of their fabled brother.

Beovox Uni-Phase S75

Pressure chamber speaker with linear phase sound reproduction and wide frequency range: 36 – 20000 Hz. Was suitable for placement in a shelving system but also available with aluminium pedestal for those who prefer a free-standing model. Speaker units included a 25cm woofer, a special 12,5cm Phase Link unit, a 5cm mid-range dome and a 2,5 dome tweeter. Volume was 40 litres; weight 11kg
