BeoCord 8000

Bang & Olufsen BeoCord 8000

When you used metal tape cassettes in the Beocord 8000 you obtained the same high quality sound you were used to from a good gramophone record. Careful choice of components and materials, creative engineering and technical excellence all made this possible.

But superb sound reproduction was only one of the benefits you got from this advanced cassette deck, which replaced Beocord 5000. Of equal importance was the fact that time, through Beocord 8000, came to the cassette deck. Bang & Olufsen used it to measure tape consumption. Quite simply, instead of using meaningless digits, minutes and seconds were used instead. This allowed you to locate specific tracks of music easily and accurately for immediate replay. Just tell the Beocord 8000 where to start, in minutes and seconds and let the set’s microcomputer do the rest.

This feature also helped you plan recordings and thereby ensure maximum use of your tapes. During play, Beocord 8000 measured and displayed the exact amount of tape consumed so that you always knew how much playing time was left on the cassette. And the Beocord wouldn’t let you make mistakes: if you gave incorrect instructions, reject signals flashed on the set’s display panel. The microprocessor which made the real time counter possible was also used to provide a digital clock for timer recording. In normal use the clock did not show on the display, but it could be programmed to start the tape either playing back or recording any time within 24 hours.

The button marked ‘RETURN’ afforded great convenience during recording. Together with the automatic tape position indicator, it enabled you to edit your tapes electronically. The split-channel Peak Programme Meter eased the setting of recording levels and was extremely accurate. It indicated the actual signal that was being fed to the tape, for each channel, rather than that which was being received at input.

Underneath the brushed aluminium panel was the cassette compartment, sliders for setting recording level, an independent slider for adjusting volume level on headphones, facilities for timer programming and adjustments for secondary functions.

For example, you could instruct Beocord 8000 to make recordings of radio programmes while you are out. In short, everything was done to ensure total listening pleasure in terms of sound reproduction and convenience.

Beocord 8000 could be used as a stand-alone tape cassette recorder or as part of hi-fi systems such as Beosystem 6000 or Beosystem 8000.

BeoCord 8004

Bang & Olufsen BeoCord 8004

Beocord 8004 had its own microcomputer which took care of most of the tasks involved in recording and listening to cassette tapes. The microcomputer was also responsible for one of Beocord 8004’s most advanced and unique features – the real-time tape counter. Actual minutes and seconds were used to measure elapsed time so you always knew how much recording time was left to fill.

Selection between chrome, ferric and metal tape characteristics was automatic. So was the operation of the HX-Professional recording system – a technique developed by Bang & Olufsen to expand the peak ceiling level of all types of tape. The provision of Dolby B and Dolby C Noise Reduction improved the sound quality of your recordings even further.

Signal input levels were indicated on electronically-controlled Peak Programme Meters that performed to standards set for professional studio and broadcasting recorders. The signal level was monitored on both recording and playback.

The tape head of Beocord 8004 was a single combination head of superb technical quality. Both the poles and the beddings were made of Sendust alloy. As with all Bang & Olufsen recorders, a special additional circuit automatically demagnetised the head each time the STOP function was used at the end of a recording.

Locating particular recordings was quick and easy using the Beocord’s computerised tape address system. Just key in the track’s start time – in minutes and seconds – press GO, and wait a few seconds. The tape automatically wound to that location and began to play.

For recording an important broadcast while you were out of the house (or when you didn’t want to spend the evening clock-watching) there was a twenty-four hour electronic timer. With a few touches to the programming buttons you could store the station, start time and stop time in the microcomputer’s memory. It then carried out your instructions at the appropriate hour – regardless of how you used the recorder in the interim.

Beocord 8004 could be used as a stand-alone tape cassette recorder or as part of hi-fi systems such as Beosystem 6000 or Beosystem 8000.

BeoCord 8002

Bang & Olufsen BeoCord 8002

Beocord 8002 was one of Europe’s most advanced cassette recorders, yet electronic automation made it by far the easiest to use. Microcomputer control meant operational errors were impossible.

A new development – the Dolby HX Professional recording system or ‘HX-Pro’ automatically optimised bias levels relative signal content, thus ensuring professional standard recordings every time, no matter whether you used, ferric, chrome or metal tapes. In addition Beocord 8002 had the ability to indicate recorded and playback time in minutes and seconds so you could plan your recordings economically.

Finding the start of a particular track was automatic: you just had to key in the required ‘address’: computer logic then found it for you. You could also program the deck to make unattended recordings at any given time within a 24-hour period.

When coupled to Beomaster 8000 all recording and playback functions could be operated by remote control using the BeoLab terminal. Beocord 8002 could be used as a stand-alone tape cassette recorder or as part of hi-fi systems such as Beosystem 6000 or Beosystem 8000.

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….

BeoCord 4500

Bang & Olufsen BeoCord 4500

Beocord 4500 cassette recorder housed exciting details and distinguished technology. Like Auto Reverse, so you did not need to turn over the tape. Automatic registration of the type of tape, and Bang & Olufsen’s patented HX-PRO recording system that provided optimal sound reproduction. Both in design and technology, Beocord 4500 was a direct extension of Beomaster 4500.

The cassette recorder featured Bang & Olufsen’s own HX-PRO recording system which ensures that recordings are made as perfectly as possible. With the Beolink 1000 terminal or by lightly touching the panel itself, you could select a particular piece of music you wanted to hear. The search system found it automatically whether it was on Side 1 or Side 2 of the cassette. For Beocord 4500 had Auto Reverse so you did not have to turn the tape over.

The recorder was also equipped with Dolby B and knew exactly what type of tape you were using. Beocord 4500 could be used as part of the Beosystem 4500 hi-fi system.

BeoCord 1500 (1979)

Bang & Olufsen BeoCord 1500 1979

Beocord 1500 matched several Beomaster receivers in design, concept and performance level. It was also technically compatible with non-Bang & Olufsen products. If you simply wanted to record and play back cassettes without any extra refinements or facilities, this deck was for you.

The slanted control panel was logically planned and really simple to use. The VU meters and sliding input control made the setting of correct recording levels easy and accurate. The 3-digit tape counter had a memory function that helped you locate the start of a particular passage of music.

Quality recording and playback was further ensured by the super Permalloy tape head, highly stable motor/drive system and Dolby B Noise Reduction circuit.

BeoCord 900

Bang & Olufsen BeoCord 900

Beocord 900 was the simplest of Bang & Olufsen’s range of cassette-recorders.

Your only task was to choose the type of tape to put in: Cr02 or normal. Beocord 900 had large easy-to-read VU meters and recording controls were separate for left and right channels. There was a socket for a microphone and a push-button for mono recordings.

Tape-heads were made of Super Permalloy, a hard and extremely durable material which ensures a long useful lifetime. Wow and flutter was less than 0.28% (JIS method). Signal-to-noise ratio was better than 50 dB with chromium dioxide tapes.

BeoCenter 3500

Bang & Olufsen BeoCenter 3500

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 5000

Bang & Olufsen BeoCenter 5000

If space was limited in your home but you still wanted top-class sound reproduction from your hi-fi, Beocenter 5000 was the perfect answer. It offered high-technology performance from radio, records and cassettes, yet measured only 72 x 38 x 9,5cm. Each sound source could compete on merit with more expensive ‘separates’. The three high-performance components were integrated together into a single unit to give the best of all possible worlds.

The 2 x 40 watts RMS amplifier meant high power with minimal distortion – less than 0,1% at full output. The automatic record deck had a low-mass, low-inertia tone arm carrying an MMC 20E pickup and a precision-built electronic servo drive system for perfect speed accuracy. The cassette recorder was capable of the highest performance levels as it included Dolby Noise Reduction circuits, metal tape facility, automatic ferric/chrome selection, Sendust tape head and 4-digit electronic tape counter. The radio covered Long, Medium and FM bands, with five pre-set stations offering instant, press-button tuning.

Beocenter 5000 offered the same musical facilities and powerful 2 x 40 watts RMS output as Beocenter 7002. The two models were identical in the matter of sound quality too, but only the Beocenter 7002 had Bang & Olufsen’s very advanced timer-track location and remote control systems. The black anodised lid of its cassette compartment further differentiated Beocenter 5000 from the 7002.

BeoCenter 7000

Bang & Olufsen BeoCenter 7000

Beocenter 7000 upon its release, represented one of the most advanced hi-fi centres on the market. One touch produced instant music from a record, cassette tape or an FM or AM radio station. Illuminated symbols on the set’s communication panel confirmed instructions or rejected mistakes and kept you informed on the set’s operational status at all times.

in short, Beocenter 7000 offered two-way visual communication in high-fidelity.

The cordless remote control module put you in command of most of the functions from anywhere in the room. You could select any programme which would also switch on the set. You could regulate the volume – 2 x 40 watts RMS – make cassette recordings, and switch off the set. Comprehensive memory and timer facilities enabled you to program the set’s microcomputer to operate within a 24-hour period. It could record an important radio programme while you were out, and even instruct the Beocenter to wake you up with an early morning broadcast.

Each of Beocenter 7000’s three sound sources had the quality and performance level normally found in much more expensive separate units. The record deck had Electronic Servo Drive for absolute speed accuracy and its operation was fully automated. Stop, start or pause could be controlled via the remote control terminal. The cassette recorder had a Sendust record/replay head and a double-gap erase head that could even cope with metal tapes. You could locate any point on the tape simply by asking the set’s microcomputer to search for this required counter reading. The radio had facilities for pre-setting 5 FM and 1 AM stations which could then be selected instantly at the touch of a button.

Beocenter 7000 was designed by Jacob Jensen. In 1979 three more of the designer’s creations for Bang & Olufsen were included in the Design Collection of the Museum of Modern Art in New York including the Beocenter 7000 music system.
