Rega Fono MC MK4 Phono Stage

The Rega Fono MC MK4 is a dedicated moving coil phono stage designed to maximize the potential of any low output moving coil (MC) cartridge. It is built to be effective, easy to use, and above all, to reproduce music with exceptional clarity. Housed in a brand new, redesigned aluminum case that matches the aesthetic of Rega's latest electronic components, the Fono MC MK4 is the culmination of years of trickle-down technology from Rega's more expensive and successful phono stages.

Key Features

• Dedicated Moving Coil Stage: Engineered specifically to handle the low output of MC cartridges, ensuring optimal signal amplification.
• Fully Adjustable: Features convenient rear-panel DIP switches for full adjustability of gain, resistance, and capacitance.
• Low-Noise Discrete Input Stage: Utilizes a high-quality Linear Systems LSK389 FET in an all-discrete input stage for extremely low noise and high linearity.
• High-Quality Components: Employs audiophile-grade polypropylene capacitors in the signal path and RIAA equalization circuits for a pure, transparent sound.
• Latest Design Case: Housed in a precision-machined aluminum case that provides a rigid, non-resonant housing and a modern aesthetic.

The Art of Adaptability

One of the standout features of the Fono MC MK4 is its remarkable adaptability. While specifically designed to complement Rega's own moving coil cartridges, its fully adjustable gain and loading settings allow it to be seamlessly integrated with a wide range of third-party cartridges. With the convenient DIP switches on the back panel, you can precisely match the Fono MC to your cartridge's specific requirements for resistance and capacitance, ensuring you get the absolute best performance from your entire vinyl playback system.

High-Performance Circuitry

The Fono MC MK4's core is its high-quality, discrete input stage. By using a low-noise LSK389 FET, Rega has ensured that the Fono MC has a high input impedance, which means the amplifier circuit has a minuscule loading effect on the cartridge. This allows the cartridge to perform with complete freedom and accuracy. The signal then passes through a two-stage RIAA equalization circuit that uses a MUSE operational amplifier and polypropylene capacitors, preserving the integrity and tonal balance of the music.

Design and Aesthetics

The Fono MC MK4 benefits from a brand new, redesigned aluminum case that provides both aesthetic appeal and functional excellence. The precision-machined case offers a rigid, non-resonant housing that protects the sensitive electronics from vibrations and external interference. The aesthetic design was considered as important as its electrical capabilities, giving it a modern look that can easily integrate into any hi-fi system, perfectly matching other new Rega components like the Neo MK2 and the Fono MM MK5.

A Sonic Leap Forward

The Fono MC MK4 delivers a sonic performance that is both musical and revealing. It is praised for its ability to produce a more intimate and palpable soundstage, with a firm, tight bass and an exceptionally clear, extended high-frequency response. The Fono MC presents music with a sense of potency and dynamism, bringing recordings to life with a visceral impact. It is a serious component for the discerning vinyl enthusiast who demands a high-fidelity experience without compromise.
