This deck was a variant of the Beogram 4002 but fitted as standard with a CD4 decoder. As with the 4002, there were two clear models , the earlier with the AC motor and the later with a DC motor.
The DIN plug was unusual in that it carried 4 discrete channels and was therefore best suited to the Beomaster 6000 or 3400. It did have a built in RIAA though and would play stereo records perfectly happily as the rear channels could be switched off.
The cartridge specified was the MMC6000, the ultimate cartridge in the range designed by and bearing the name of one of B&O’s pre-eminent engineers, Subir Pramanik.
Beogram 3400 was designed to play back quadraphonic-encoded records and incorporated an MMC 5000 with a Shibita diamond stylus. An optional CD4 decoder could be specified to allow play back of that type of LP as well SQ discs which could be played by any record player.
Quadraphonic sound
Bang & Olufsen produced two quadraphonic systems in the 1970s. The top model was Beosystem 6000 which comprised Beomaster 6000 and Beogram 6000. Beogram 6000 was a development of Beogram 4000 in that it was a tangential tracking turntable. It had an inbuilt CD4 decoder which was switchable. When ‘on’ it would detect the presence of the carrier frequencies and a display would illuminate on the record deck’s display as ‘4ch’.
The output of the Beogram was at line-level whether in 2- or 4-channel mode. The deck was attached to Beomaster 6000 via a 5-pin DIN lead with all the pins being wired. In Beomaster 6000 there was a replaceable board with a SQ decoder as standard. This was manually switchable. The operator therefore still needed to know the type of quad recording that was to be played. The purpose of the removable board was to allow upgrading should the record industry ever get its act together and find a common standard!
The second system was based on Beomaster 3400 and Beogram 3400 which had a radial deck and a smaller and simpler receiver. This again had similar functions. Beomaster 4000 and a few others had a facility called Ambiophonics which used a system of simulated four track sound from stereo records. Two Bang & Olufsen cartridges were made for playing CD4 records:
MMC5000 used a fairly standard Shibata profile
The top of the range MMC6000 used a profile designed by one of their own engineers – Subir Pramanik – and which bore his name
Beogram 2000 was an integrated two-speed (33rpm and 45 rpm) high-fidelity stereo record player with high specifications. But it was the simple, easy operation which was the most unique feature in Beogram 2000. A single master control executed all the essential functions.
All you need to do was to select the size of a record, 7″, 10″ or 12″ and press the button marked LIFT. Immediately, the turntable began to rotate at the correct speed (33 or 45 rpm) and the pick-up lowered into the first groove. At the end of the record, the pick-up arm returned to its resting position and the turntable switched off. Beogram 2000 was fitted with its own pick-up cartridge, SP 10A. This had a spherical naked diamond stylus.
Recommended- stylus pressure was 2 g. Its frequency range was 20-25.000 Hz ±3 dB. Distortion was lower than 1%, wow and flutter lower than 0.12% and rumble better than 60dB. Thanks to the pendulum suspension of the turntable and its pick-up am Beogram 2000 was insensitive to vibrations. A transparent dust lid was fitted to Beogram 2000. It could be opened at any angle up to 60 degrees or you could slide it off with ease.
This deck finally gave the ‘peg platter’ decks a proper lid. Not quite as advanced as the 1202, it was in all ways apart from the lid, a Beogram 1203.
Beogram 1203 was an automatic, high-fidelity stereo record-player with high specifications. It was beautifully-styled and extremely easy to operate. All you need to do was select the record size: 7″, 10″ or 12″ and press a button. The turntable automatically selected the correct speed: 33% or 45, and the pickup was lowered into the first groove.
At the end of the record, the arm automatically returned to its resting position and the turntable switched off. Beogram 1203 was fitted with its own pick-up cartridge, the SP 14A which had a spherical diamond stylus and a stylus pressure of 2g. Its frequency range was 20,000 Hz. ±3 dB. Distortion was lower than 1%, wow and flutter lower than ±0.15 % and rumble better than 58dB. The turntable and pick-up arm had a pendulum suspension which made the record-player insensitive to vibrations. A transparent dust lid and a spindle adaptor for playing centreless records were supplied with Beogram 1203.
It was in fact rather simpler than its immediate predecessor, the 1202 , and was based on the Beogram 2000 rather than the top of the range 3000.
Beogram 3000 was an automatic high-fidelity stereo record-player with specifications which easily complemented those of Beomaster 3000-2.
It was fitted with an SP 12A pick-up cartridge which had an elliptical naked diamond stylus, with a stylus pressure of 1,2g. Frequency range was 20 – 25000 Hz ±3 dB and distortion was lower than 1%. Wow and flutter was less than ±0.09% and rumble was better than 62dB. Beogram 3000 was easy to operate: you simply selected the size of record you intend to play – 7″, 10″ or 12″ – and press a button. The record-player automatically selected the record speed, 33 or 45 rpm, and lowered the pick-up into the first groove.
When the record ended, the pick-up arm lifted up, returned to its resting position and the turntable switched off. The turntable and pickup arm had a pendulum suspension which made the record-player insensitive to vibrations. The deep furrows in the turntable made it easy to pick up records. A hinged dust lid was fitted; it could be set at any angle up to around 60 degrees or completely removed by a simple sliding action.
Beocenter 1800 fulfilled hi-fi standards by a wide margin. The product was also way above the average in terms of ease and operation. Experience from Beomaster 1100 and Bang & Olufsen’s integrated gramophones were combined in the special space-saving unit, which on a specification level was on a par with many separates.
The FM section had automatic frequency control (AFC), four pre-set stations and light indicators. The amplifier’s power output was 2 x 22 watts RMS with less than 0,3% distortion at full power output.
The integrated gramophone was fully automatic. The user simply chose the size of the record and pressed a button – the machine did the rest. The pickup arm was of magnesium which was extremely light. This, together with the MMC 3000, a low-mass cartridge, made this one of the very few turntables on the marker that was capable of tracking warped records. The anti-skating device also worked automatically.
The pickup arm and the turntable mechanism had a special spring suspension which made the turntable shock and vibration resistant.
Records could be played with the dust lid closed, thus protecting both the turntable and the record collection from damaging dust particles. Beocenter 1800 had connections for tape recorder, two sets of stereo speakers and a pair of headphones.
When connected to a pair of Beovox Uni-Phase passive loudspeakers, it was known as Beosystem 1800.
The amplifier section of Beocenter 1400 offered qualities which were unusual for a combination product in this price-range. Frequency range was 20-30.000 Hz, with harmonic distortion of less than 0.5 % at maximum output. Power output was 2 x 20 watts RMS or 80 watts total music. The technical data of the FM section, like those of the amplifier fulfilled the DIN 45500 high-fidelity norms by a wide margin. A wide frequency range was obtained both on mono and stereo reception. The balanced light indicator was a simple but effective aid to accurate tuning. The automatic frequency control (AFC) facility allowed precision tuning.
Beocenter 1400 – “Each unto his own taste” – especially with music.
Receiving distant stations was no problem on Beocenter 1400 owing to the receiver’s high sensitivity (better than 1.8 uV IEC). The compact cassette section had its own operating facilities: ON/OFF switch and piano key push buttons for recording and play-back functions. You could switch between chromium dioxide and normal tapes. Recording level was controlled by a handy slider on a numerical scale and light indicators: Red or green light showed overloading or satisfactory recording level. Tape-heads were of super permalloy, an extremely durable material which ensures a long useful lifetime. Wow and flutter was less than ±0.28% (JIS norm).
Signal-to-noise ratio was better than 50 dB with chromium dioxide tapes. Bang & Olufsen placed emphasis on good station separation in the AM section (long and medium waves) without sacrificing sound quality. A slider control aided radio tuning. Beocenter 1400 had sockets for a record player, headphones and loudspeakers. An extra tape or cassette-recorder could also be connected. Beocenter 1400 utilised the (then) latest electronic components: Darlington transistors, field effect transistors, integrated circuits and ceramic filters.
When combined with Beovox 1702 loudspeakers and/or Beogram 1203, the system was known as Beosystem 1400.
Beogram 1102 was a fully automatic, hi-fi stereo record player with electronic servo-drive and high specification level. Operation was easy and straightforward. All functions were controlled by pressing the rectangular operating panel and if dissatisfied with the pitch of the record, speed could be adjusted by depressing the panel and rotating the little thumbwheel.
The pickup was an MMC 3000 with a spherical diamond. It tracked records at a stylus pressure of 1,2 grams. In order to fully exploit the pickup’s outstanding qualities, B&O constructed an extremely light magnesium pickup arm which, together with its unique suspension, ensured low inertia and thereby good conditions for correct contact between stylus and both walls of the record groove – at all times. Even warped records could be played satisfactorily.
Despite high specification levels, Beogram 1102 and 1902 automatic record-players are extremely easy to operate. All the technicalities are hidden under the surface.
Bang & Olufsen’s Electronic Servo Drive ensures that the rotatory speed of the Beogram 1102 and 1902 was always correct despite variations in the mains current supply. This is so because the system has a special feedback circuit which effects automatic corrections to compensate for these inherent variations
Beogram 1102 could be made up as part of the Beosystem 1100, together with other compatible Bang & Olufsen products
Beogram 1102 UK price in 1978: £97.00
These decks are beautifully made and offer super sound quality for almost no money. Much easier to maintain than the tangential decks simply because they are very simple! Excellent isolation from external vibrations – strongly recommended – and they were when new by Hi-Fi Choice! Simpler than the earlier 1100 – and better for that! A DC motor replaced the AC motor fitted to the 1100 and was electronically regulated with speed adjustment done through a potentiometer as opposed to the complicated measures used in earlier decks. This method would roll out across the range of Beograms.
