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.
A combination system with the quality and specifications of “separates”
Beocenter 3500 was built upon the Beomaster 3000 and combined a top quality FM tuner, an automatic record-player and a powerful stereo amplifier. The tuner had six pre-set stations for instant selection, plus a large manual tuning scale. There was an illuminated tuning indicator and a signal-strength meter to assist easy, accurate tuning. The powerful amplifier produced 2 x 40 watts RMS of high-fidelity output and was equipped with switchable filters.
There was a comprehensive range of connection facilities including sockets for two pairs of loudspeakers, headphones and a tape recorder with monitoring. The record-layer was fully automatic with one master-control for operating all functions. You only have to select the control position applicable to the size of the record, and touch a button. Beocenter 3500 was an ideal, simple way of enjoying high quality sound from records and radio. It was fitted with a robust hinged dust cover which protects records during play.
Features:
In the high-fidelity amplifier section, emphasis was placed on specifications, frequency correction and connection facilities. The LOUDNESS feature permitted switching between an objective or a subjective linear reproduction and the LOW and I-II filter controls gave a sharper regulation of frequencies in addition to the normal bass and treble controls. The LOW filter helped reduce rumble resulting from poor records. The EH filter reduced hiss. There were sockets and push buttons for two pairs of loudspeakers. The headphone socket was on the receiver’s front. The tape connection facilitated AB monitoring. All input signals could be adjusted at the receiver’s base to give equal sound intensity on all programme sources. The FM section had six pre-set FM station selectors.
A light indicator assisted accurate tuning and an illuminated meter registered the signal strength of a station. The FM section was extremely sensitive (better than 1.4 uV I.E.C.) and harmonic distortion was a mere 0.4%. Field effect transistors, ceramic filters and integrated circuits were used. The built-in record-player was perfectly matched to the rest of the unit, from a specification point of view. The fitted pickup cartridge, the SP 10A (later SP 12A) had a spherical naked diamond and a stylus pressure of 1.2 grams. 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 60 dB.
The record player section was easy to operate: you simply selected the size of the record you intend to play – 7″, 10″ or 12″ – and press a button. The record-player automatically selected the correct speed – 33 or 45 rpm – and lowered the pick-up into the first groove. When the record ended, the pick-up arm returned to its resting place and the turntable switched off. The turntable and pick-up arm had a pendulum suspension which made the record-player section insensitive to vibrations. Deep furrows in the turntable made it easy to pick up records. A stroboscope and a spindle adaptor for centreless records was provided. Beocenter 3500 was fitted with a hinged dust lid which was easily removed by a sliding action.
Beocenter 3500 had an extra Phono input. This was a ‘hang over’ from the Beomasters of the time which allowed two Beograms to be connected to the music centre. However, Phono 2 needed an RIAA pre-amplifier as it required a line level input. This feature became ‘Tape 2’ in later models.
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.
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
Beocenter 3300 combined a powerful AM/FM stereo receiver with an automatic record player. Technically identical to the Beomaster 2200, the receiver section offered programmes on FM, long and medium wavebands and up to 2 x 40 watts RMS amplification with low distortion levels. It also had the same logical operation facilities.
The record player had a spring-suspended rotatory mechanism and an electronic servo drive system which ensured accurate turntable speed – even during variations in the mains current supplies. A special pendulum leaf spring suspension made the arm and platter immune to external shock and vibration which causes most other record players to mistrack and damage the record and sometimes even the stylus.
All functions of the record player were operated by touching a single button. The start/play/stop cycle is entirely automatic and moves, lifts or lowers the arm much more delicately than could the human hand. The MMC 20E cartridge carried an elliptical diamond stylus.
Beocenter 3300 had sockets for a tape deck, an extra record player, headphones and two sets of stereo speakers. The unit could be made up as part of the Beosystem 3300, when linked together with other compatible Bang & Olufsen products.

Beolit 707 received radio programmes on FM, long and medium wavebands. This portable radio was Bang & Olufsen’s handiest music system. Its sound reproduction quality was so outstanding that it invites even critical music lovers to listen to music programmes when they are away from home.
Power input was specified at a pure 1 watt and frequency range was 65-20 000 Hz: exceptional for a transportable radio receiver. A large tuning scale with thumb wheels made tuning easy. Bass and treble was adjusted separately and there was an AFC facility to keep FM stations correctly tuned.
Beolit 707 could be plugged into the mains supply or run from batteries. The cabinet was finished in coloured Nextel – a synthetic material with a suede-like finish which is washable ands scratch-proof. It was designed by Jacob Jensen, the same as its FM-only sibling, Beolit 505.
The Beolit was one of the very few portable radios that were suitable for reproducing more than just news broadcasts. Sound quality was so good that music programmes could be reproduced with a quality that made them worth listening to. The Beolit was fitted with a mains transformer and a detachable lead. Operation was simple and problem-free. And since portable radios can end up in unenviable situations, the Beolit was constructed to withstand some rough treatment.
A robust chassis protects the internal circuitry and a special surface treatment protects the radio from scratches. Dirty marks were easily removed with a damp cloth.
Beolit 505 was a pure FM radio with AFC facility to ensure clean, sharp reception. It had an in-built large, high quality speaker together with a built-in telescopic aerial. It had six programme indicators (affixed to sliding tuning scale) and connection for a tape recorder. It was designed by Jacob Jensen, the same as its FM and AM bigger brother, Beolit 707.
