    Product Overview

    Product Overview

    Now housed in a brand new redesigned case to match the new Fono MM MK5 and Neo MK2 and Rega’s latest range of electronic components offering a modern look guaranteed to integrate in to any hi-fi system.

    The Fono MC MK4 has been designed to be effective, easy to use, and above all, to reproduce music. 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.
