Please message me for that serviceTESTIMONIALS Courtesy of Beoworld.org MMC stands for Moving Micro-Cross; the patented moving-iron principle upon which all B&O cartridges were based. 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 No cartridge will ever reach this ideal unless the Laws of Physics can be repealed.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 cartridge If 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.MMC4 Product Specifications Description Titanium-bonded elliptical diamond, mounted on a tapered aluminium cantilever Tracking force - grams 1.2 Diamond Stylus Elliptical Cantilever tube.

You receive the assurance of a properly connected system, including optimum placement design and the benefit of a full demonstration, highlighting the tips and techniques garnered from decades of experience and expertise. Recent installations have ranged from a single Beocenter being connected to the existing speakers and unit for an 89-years young-lady for a few hundred pounds to a multi-room, Beocenter, Beogram, Beovox and B&O dedicated cabinet and stands combination, with remote control, for a few thousand pounds.Please use the ask a question feature to access the pre-sales telephone number to discuss your requirements.SOURCING SERVICE:Cant find that B&O product that youve yearned for since you were a kid?

It is the buyers responsibility to check before purchasing for their own countrys charges. VOLTAGE:All electrical items are UK voltage (240v) and B&O UK type xxxx unless otherwise stated. I dont like to disguise the postage and packaging costs in the item price. This shipping price includes, packing materials, insurance and first class tracking that is an unfortunate necessity due to buyer fraud. It is not even the full cost, only the Royal Mail charge. Thank you for your understanding.

The aluminium cover over the cassette & functions area works perfectly after having a brand new hinge and grease. The Rosewood veneer is in excellent condition. The radio works perfectly on every setting and the illuminated display is fully working. The unit has had new rubber feet ,as these always perish and it is important to keep the unit level and avoid scratches on your furniture. The Beocenter 7007 has been fully cleaned, tested and serviced and is in excellent condition. Please study the photos as they make up part of the overall description. Thanks Postage will be via courier and will be fully insured and tracked. The price of the postage reflects the weight and value of the Beocenter. Personal delivery will be considered within a certain radius of Wilmslow or a half way meet. BeoCenter 7007 Manufactured: 1983 - 1987 Designer: Jacob Jensen Colours: Rosewood, Teak Beocenter 7007 (also known as Beosystem 7007) Top quality sound and maximum listening comfort were the main features of this integrated hi-fi system. Records, radio, cassette tapes and a 2 x 40 watts RMS stereo amplifier could all be controlled from anywhere in the room using the slim remote handset. Without moving more than a finger you could select any sound source, adjust volume level, fast wind the tape and even make recordings. This supreme ease of operation was made possible by microcomputer technology. In addition, there were two user-programmable microcomputers which allowed you to make unattended recordings at any time within a 24-hour period, or to play any sound source automatically at a pre-selected time - day after day, if you wished. A further advantage was easy access to cassette recordings: just key in the appropriate counter reading (address) and the cassette would fast wind to the required passage of music. Ferric, chrome or metal tapes could all be used and Dolby B Noise Reduction was included to ensure clean, hiss-free recordings. The automatic record deck had an ultra-lightweight arm carrying the MMC4 and MMC5 pickup cartridge. The radio section covered Long, Medium and FM bands with facilities for pre-setting 6 favourite stations. The recommended speakers were the Beovox S55 . Speaker pedestals or the SC70/ SC77 hi-fi cabinet could be added optionally if required.

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.
