B&O MMC4 Cartridge w/ 1/2" Adaptor

At Bang & Olufsen we have been gradually improving the Moving Micro Cross, which has been the generating element in our cartridges for a number of years. With the new MMC generation, the Moving Micro Cross is smaller and lighter than ever, which means less wear on your records. The precise engineering of the micro cross also provides superior channel separation. By placing the micro cross in a powerful magnetic field we have succeeded in creating a cartridge of very small dimensions, while still retaining a high output voltage. The minimum weight with bracket is only 3.3 grams, which gives the optimum compatibility with the best tone-arms on the market. Information on the record is led via the stylus and cantilever to the micro cross. As a result the micro cross moves, causing variations in the powerful excitation current which comes from the fixed magnet and flows through both the micro cross and the four poles. The varying excitation current is transformed into energy by the four push/pull coils wound on the poles and led to the amplifier via a cable.
