The diamond profile was similar to that of the MMC20CL being line contact. The way to look at these cartridges was to imagine an elliptical profile but with both the front and rear facets being scooped out. In this way the vertical contact surface was maximised and the horizontal element kept to a minimum.The MMC1 and MMC2 were essentially the same cartridge with the MMC1 using the best specified diamond tips. The MMC system was carried over from the SP series but taken to an even smaller level.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lost and none added from extraneous sources.No cartridge will ever reach this ideal unless the Laws of Physics can be repealed.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 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.MMC2 SpecificationsNude multi-radial Contact Line diamond, mounted on a sapphire cantilever Tracking force - grams 1 Diamond Stylus Cont. line nude Cantilever tube Sapphire Effective tip mass mg 0,3 Compliance mg/mN 30 Frequency 20-20000 Hz=/-dB 1,5 Channel separation 1000>dB 25 Output mV/cm/s RMS 0,6 Cartridge weight gram 1,6

Here we have my Pioneer PD 7700 CD Player in the rare silver finish complete with original box,packing and instructions.Although the unit powers up and the display is fine and the drawer opens and closes as it should, the unit refuses to play so it is for spares or repair,As you can see, it is in excellent cosmetic condition with an unmarked fascia.Far to good to scrap so hopefully someone can repair it.There is NO remote.UK AUCTION ONLYCollection from Darley Dale DE4 is fine.Any questions, please ask.
