Rega Fono Moving Coil Phono Stage Overview

As lovely as an LP’s analog signal may sound, a microscopic needle wiggling around in an equally minuscule groove doesn’t generate much energy. And when the phono cartridge is the moving-coil type prized by audiophiles, the output is lower still – as much as 1,000 times lower than normal line level! Rega’s Fono MC Phono Stage boosts the ultra-low signal of a moving-coil cartridge to match the line-level inputs of any modern amplifier, preamp, or powered speakers. Styled to match the look of Rega’s entire line of electronics (and perfect with Rega’s Planar 6/Ania cartridge combo), the Fono MC nonetheless will bring the finest out of any of today’s moving-coil cartridges. You get adjustable impedance and capacitance switches to match the circuitry perfectly to the cartridge (ultra-low level inputs are particularly susceptible to load variations). You get switchable gain, all-analog circuitry using top-quality, low-noise discrete components. And the whole thing is hand-assembled and tested in Rega’s factory in the southeast of England. Unless your receiver has an input specifically marked MC photo, you’ll need a top-notch phono stage like the Fono to unlock the finest reproduction of your treasured LP collection.

Product Information

The Fono MC has been designed to be effective, easy to use, and above all, to reproduce music. The Fono MC 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 compatible with most low output MC cartridges.

The aesthetic design of the Fono MC was as important as the quality of its electrical capabilities, so it benefits from the same aluminum case as the Rega TTPSU and Fono MM amplifier, giving it a design which offers a familiar feel and moreover brings it in line with its illustrious bigger brothers. The new Fono MC circuit resulted from the design work carried out on the Aria phono amplifier.
