Rega Fono MC MK4 Phono Stage

Description

FONO MC MK4

The Fono MC MK4 is an exceptionally high-quality MC phono
stage designed to maximize 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 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.

KEY FEATURES

• Lifetime
  warranty against manufacture defects

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.

The aesthetic design of the Fono MC MK4 was as important as
the quality of its electrical capabilities, so it benefits from the same new aluminum
case as the Rega Neo MK2 PSU and Fono MM MK5 phono stage, giving it a design
which offers a familiar feel and moreover brings it in line with its
illustrious bigger brothers.
