Rega Fono MC MK4

The Fono MC MK4 is an exceptionally high quality MC phono stage designed to maximise the potential of any low output MC cartridge. Although specifically designed to complement the latest Rega range of moving coils you will find full adjustability for gain and loading via dip switches conveniently placed on the rear panel making the Fono MC MK4 compatible with a wide range of third party low output MC cartridges. Now housed in a brand new redesigned case offering a modern look guaranteed to integrate in to any hi-fi system.

The Fono MC MK4 uses the Linear Systems low noise LSK389 FET in an all discrete input stage where low noise and linearity are vitally important to get the best from an MC cartridge. Because of the high input impedance of FET, the loading effects of the amplifier circuit are minuscule and do not affect the performance of the cartridge.

A MUSE operational amplifier is used in the RIAA equalization amplifier. Polypropylene capacitors have been used in the signal path and in the RIAA equalization circuits. There is selectable input loading for both resistance and capacitance along with two different gain settings located on the back panel making the Fono MC MK4 compatible with most low output MC cartridges. The new Fono MC MK4 circuit resulted from the development work carried out on the hugely successful Aria phono amplifier.
