Cartridge

The cartridge performs this conversion at the end of the tonearm. Moving-magnet (MM) and moving-coil (MC) cartridges use different magnetic generators. The phono stage has a separate job: it amplifies their small signal and applies playback equalisation, correcting the tonal balance used when the record was cut.

Mechanical matching starts with the mount, cartridge mass and compliance: how easily the stylus suspension flexes. Mass and compliance need to suit the tonearm. Set tracking force according to the cartridge maker’s instructions; cartridge weight is a different specification.

For the electrical match, check output voltage and the recommended load against the phono input’s settings. Loading means the resistance and capacitance presented to the cartridge. An MC label does not automatically require an MC input: some high-output MC cartridges work with MM inputs.
