Master Control Panel 7700Tested and shown to work with the latest of the Beocenter models 7007 and 7700 Two-way communication so the Beocenter tells the MCP what is happening. Particularly useful when you are in a different room to the unit (7700 only) Automatic ambient-sensitive backlight (in the 1970s!) illuminates the display in low light conditions and is still workingUse with a Master Control Link system to operate from anywhere in the house.Wire-in multiple speakers to produce sonics that are FAR SUPERIOR TO SONOS or any other wireless multi-room system AND ID LIKE TO SEE YOU PLAY YOUR VINYL THROUGH THEM...! Dont be fooled by the marketing of these companies. No wireless system can match the fidelity of a decent wired one like B&O Operate the programmable features on your Beocenter 7700 AND 7007 from the comfort of your chair/bed/(bath - as long as you are really careful!)The forerunner and proof of concept that went on to spawn the MCP 5000, 5500 and 6500Match with:Beocenter 7700Beocenter 7007Upgrade with:Nothing, its exclusive to these 2 BeocentersMost of these are available in my other listings already or I have them in stock so do have a look below, if not I can source them for you in a few days. Please message me for that serviceTESTIMONIALS DescriptionAt the time of its introduction, the Master Control Panel 7700 was the most ambitious remote control terminal to be offered by B&O. Intended for use with the Beocenter 7700, this advanced product made use of a new technique, two-way infrared communication. In simple terms, this meant that both the terminal and the Beocenter could transmit and receive data via the IR link, allowing the terminal to display what the audio system was actually doing (not just which keys had been pressed recently).The reason behind this level of sophistication was that the Beocenter 7700 was intended for use as the centre of a multi-room link system, so knowing what the main system was doing without having to go and have a look was a real advantage. Using the Link 82 transceiver unit, the Master Control Panel could show, for example, which radio station was playing or confirm that a recording was taking place.The Master Control Panel 7700 was also the first B&O product to use LCD displays. These were similar to the types used in the watches and calculators of the day, and could only show a limited variety of simple shapes. In the case of the Master Control Panel 7700, a more flexible display was formed by using three units, one to show the volume and muting status, one to show the source selection and one for miscellaneous functions such as “record”. A disadvantage of the LCD technique was that the displays were “reflective” and could only be read in good ambient lighting. To get around this, a backlight was fitted behind each one, though to save power only the display(s) in use were lit, and then only when a built-in sensor deemed it dark enough for the backlight to be worthwhile. The light sensor was hidden behind a small green square on the display panel, next to a “transmit” indicator of identical appearance.Unlike later two-way IR products, the Master Control Panel 7700 could function normally even if the returned data was not received. It could therefore be used with the Beocenter 7007 as well, though much of the advantage was lostManufactured: 1983 - 1986 Designer: Jacob Jensen Colours: Black WORLDWIDE carriage may cost more OR LESS!! than the listing states (I have to enter an estimated figure) and will be charged in full as per the service chosen and destination country.

I NEED YOUR FULL ADDRESS FOR THISPostage/Carriage charges: You may have noticed that these has risen lately. The most recent increase is because Ebay are taking 10% of sellers postal fees for their own profit. Before this, both Royal Mail and Hermes increased their charges, particularly for smaller items. Im sorry that these have to be passed onto you. We also try to recycle packaging as much as we can but it will always be top quality and we usually double-box where appropriate too.DELIVERY TO CHINA, ISRAEL, AUSTRALASIA, INDIA, RUSSIAN FEDERATION AND SOUTH AMERICA WILL BE ROUGHLY DOUBLE THE QUOTED INTERNATIONAL PRICE.

Vintage B&O Bang & Olufsen Beocenter 7700 in Rosewood for Spares or Repair This auction is for a classic B&O Beocenter 7700 Music System with Record Player, Cassette Player & Radio When it came to me the Tonearm had been detached and I replaced it, it was then working. I replaced the belts on the cassette deck and this was then working. The tuner was working until there was a loud buzz and the system shut down. Since then it will power up but does not respond to any controls. The amps are still working as you can hear the system come on. This may be a simple fix for someone who knows these systems but it is beyond me. Other issues:The Record Deck cover has detached after the B&O double sided foam has perishedOne of the hinges that the Record Deck lifts on has broken and the aluminium deck is loose.The connections from the Amp to an internal circuit board has broken, see pictures, this just means that you cannot switch speaker outputs but you can still connect a pair of speakers to the trailing wires. I will include the broken piece of the cicuit board so it could be repaired.I will also include the old tonearm and all the screws that have been removed There are various cosmetic blemishes, nothing major but it is a used item. NB: There is no cartridge included but I am selling an MMC 3 Cartridge on a separate listing. Please see pictures and feel free to ask me any questions. Due to the delicate nature of this item we recommend collection from Taunton or we can organise a courier at cost. Please see our other listings for more Bang & Olufsen Equipment including another Beocenter 7700 From Beocentral:The ultimate 7000 series music centre. Launched alongside Beocenter 7007, it shared the latter’s styling updates, but went further, with an aluminium cover over the turntable, opened with a pushbutton and incorporating an automatic light, which matched the cover over the tape and programming sections. This made the range-topping Beocenter look very sleek, and clearly different from the other models.All the technical improvements from the 7007 were also included, and were in some cases improved, an example being the standard fitting of an MMC 3 pickup. The big news however was the two-way remote control system, based around an infra red transceiver in the Beocenter and a new type of terminal, the Master Control Panel. The Master Control Panel 7700 featured three LCD display panels, the data on which was sent from the Beocenter 7700 via and infra red link. This may seem like a gimmick, but in the context of multiroom operation it proved invaluable. It became possible for the first time to tell from a distant room what radio station was selected, or exactly what the cassette recorder was doing. The system also worked in the same room as the Beocenter, though the large LED readouts on the Beocenter front panel meant that a simpler terminal could be used, the Beocenter Terminal from the 7007 being suitable and available as an accessory.Choice of loudspeakers was left to the owner, but Beovox S 80.2 was suggested, with the new ‘C’ range of compact models possibly for a second room. Later on, the standard pickup was changed to the MMC 4, and the SC 77 cabinet became available. Throughout the life of the 7000 series, the potential customer was urged “not to mistake them for ordinary music centres”. The Beocenter 7700 reinforced this point beyond any doubt.Payment within 3 working days, returns only accepted if the item is not as described. Combined postage offered where applicable.

This unique system employed a cross-shaped armature which, among other advantages, guaranteed exceptional stereo separation since each channel moves on a separate axis.The job of any pickup cartridge is to transform the records physical profile (groove modulation) into corresponding electrical signals (which are then amplified or enlarged by the amplifier and turned into audible sound waves by the loudspeaker.A cartridge must perform three separate and exacting tasks if it is to do this job successfully. It must function mechanically (the movements of the stylus in the groove); it must function magnetically (using the physical movements to create changes in a magnetic field); and it must function electrically (using the changes in magnetic flux to generate an electrical current). At each stage, one type of energy is transferred into another, quite different, type. And the transfer must be perfect, with no energy lost and none added from extraneous sources.No cartridge will ever reach this ideal unless the Laws of Physics can be repealed. However, by understanding the relationships between the three transfer stages and continually applying refined engineering techniques, B&Os belief was that each stage of cartridge improvement would bring each successive cartridge closer to the ideal. Record wear and the cartridgeIf you take music seriously the value of your record collection is likely to be high. Many of your records are likely to be irreplaceable. You will also know that the signals pressed into your vinyl discs are very fragile indeed. The pickup cartridge can be the discs worse enemy since an ill-suited cartridge can mark a record for life in a single play.While B&O is aware that cartridge specifications are inter-related, their research shows consistently that Effective Tip Mass (ETM) is one of the major factors affecting record wear. ETM is the equivalent of the amount of inertia the groove sees in moving or accelerating the stylus tip. Consequently, the higher the ETM value, the higher the force required for a given constant acceleration. Obviously, more force results in more wear.Three elements contribute to ETM. The stylus tip (diamond) contributes with its entire weight and mass. The armature contributes between 5 - 20% of its weight and mass; the cantilever around 30%. B&O has been able to reduce ETM substantially by refining these elements and building them into an integrated unit. The result is a system which not only reduces damage to the groove walls dramatically, but also provides exceptional performance at all frequencies. Any questions just get in touch, Id be glad to help.
