The Fono MC is an exceptionally high quality MC phono stage designed to maximise the potential of any MC cartridge. Although specifically to compliment the latest Rega range of  moving coils you will find full adjustability for loading is available via dip switches conveniently placed on the rear panel with two different gain settings located on the back panel making the Fono MC compatible with most low output MC cartridges.

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 aluminium 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.

The Fono disk stage is designed to amplify the signal from a moving coil cartridge to a level which can feed into a 200mV line level input on a standard hi-fi amplifier.

Developed by our engineers, the new Ear benefits from a completely new surface mount PCB layout based on the hugely successful Brio-R amplifier. Exceptional performance is guaranteed with the convenience of independent mute, volume control and multiple connectivity options to integrate perfectly into any users system.

Power Supplies & Noise Reduction

The Ear pushes the Brio-R power amplifier circuit concept to a new level with the use of a low noise, fully regulated, supply. Noise has also been kept to a minimum by the use of an external mains transformer. The Ear exceeds the voltage requirements of IEC 268-15. This along with low output impedance makes it suitable for studio use as well as a hi-fi headphone amplifier. The Ear operates in Class A at normal listening levels.

High Quality Components

The Ear utilises the highest quality components and our engineers’ experience, to achieve the best sonic performance. Utilising the design ideals of the ‘cascaded emitter follower output stage’ with a pair of complementary Darlington output transistors, along with polyester film and Nichicon FG capacitors in critical positions, ensures it is our most advanced performing headphone amplifier to date.

Custom Case

Housed in a compact custom case, the Ear is designed to match the current range of Rega electronics with a matching, high gloss, front facia.The new Ear Headphone amplifier benefits from an all new extruded aluminium case and new styling giving it more of a family feel to match its illustrious big brothers. The Ear simply connects to the tape output of an amplifier via phono leads. The headphones are plugged into the front panel and there is a link socket in case you need your tape output sockets for other use.

Hi Fi News reviews the Rega Ear headphone amplifier:

\'The Rega Ear is lovely, in so many ways. It is beautifully made, stylish and has all the facilities you really need, plus a delightful sound that stirs the soul regardless of whatever music you put through it. Wonderfully expansive and big hearted, it makes listening a pleasure. Tonally it\'s slightly on the warm side, so suits poor quality sources down to the ground - even an iPad sounds good via the Rega!\' - January 2014.
