The configuration of the Accuphase C-57 MM/MC phono stage provides a fully balanced phono equaliser from input to output. The combination of a high precision equaliser amplifier and a dedicated MC/MM head amplifier fully optimised for the cartridge characteristics creates a highly accurate phono equaliser. As a first, the MC head amplifier uses ANCC to further improve noise performance. Dedicated MC phono balanced inputs allow for balanced connections with record players. The Accuphase C-57 MM/MC phono stage combines only the best technological advances to extract the full potential of analogue discs.
