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.

Beovox S45-2

Bang & Olufsen Beovox S45-2

An exceptional little bookshelf speaker of hi-fi quality with a frequency range of 38 – 20000 Hz and less than 1% harmonic distortion.

You will find these speakers regularly recommended on BeoWorld. They have the same height and width as the lesser S35 speakers but are 3cm deeper and 1kg heavier. This small size difference makes an immense difference to the sound though. The extra filler drive unit adds hugely to the all important midrange sound and this is, to many users’ ears, the best balanced bookshelf speaker made by B&O. What it lacks in ultimate bass, it repays in accuracy and tone. The optional floor stand is elegant and effective and worth hunting out. A capacitor change may be needed to make an old pair sing but you are very unlikely to be disappointed by purchasing a pair of these.

For those in search of more bass, S75s are the bigger brother but lack the sonic purity found in the S45.2. To beat these in this range, you need M100s and a bigger house!

Linear phase sound reproduction. Speaker units include a 20cm woofer, a special 8cm Phase Link unit, and a 2,5cm dome tweeter. Volume 25 litres; weight 7kg.

Beovox S30

Bang & Olufsen Beovox S30

Beovox S30 and S40 both used a two-unit configuration and pressure chamber design to reproduce music faithfully and clearly.

They handled up to 30 watts and 40 watts respectively and were ideal for mounting within a shelving system. Beovox S40 worked in conjunction with Beosystem 2300 if that is how you wished to use them. They featured a 20cm bass driver (woofer) and a 2,5cm dome treble unit (tweeter) offering wide frequency response and clean, clear sound reproduction.

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….
