MMC 4000

This pick-up cartridge was specially designed for use in Bang & Olufsen record-players with tangential arms.

It was designed to track SQ 4 channel matrix records and tracked both mono and stereo records extremely well. It was fitted to Beogram 4002. The stylus was an elliptical naked diamond, radii 5x17u. Recommended tracking force was 1g. Each MMC 4000 was designed as an integrated unit. This meant that all critical components were designed and constructed as an entity in order to give optimum performance.

The stylus unit was not separately replaceable as it was part of the integrated unit. Frequency range was 20-30,000 Hz ± 3 dB. Effective tip mass was a mere 0.5 mg and compliance was higher than 30x10-6 cm/dyne.
