Rega fono mm User Manual

introduction /
The Fono MM has been designed to be eective, easy to use, and above all, to
reproduce music. The Fono MM uses a fully discrete, cascaded, complementary
amplier input stage. This conguration has been proven to work well with moving
magnet cartridges. The RIAA equalization has been split into two stages to
minimise interaction. Polyester capacitors have been used in the signal path and
polypropylene capacitors are used in the RIAA equalization circuits.
The aesthetic design of the Fono MM was as important as the quality of its electrical
capabilities, so it benets from the same aluminium case as the Rega TTPSU and
Fono MC amplier, giving it a design which oers a familiar feel and moreover
brings it in line with its illustrious bigger brothers.
The Fono disk stage is designed to amplify the signal from a moving magnet
cartridge to a level which can feed into a 200mV line level input on a standard hi-
amplier.
powering up /
The Fono MM is turned on by pressing the on-o button located on the front, when
the unit is active the Rega logo will glow RED.
WARNING: We advise you to turn the Fono on rst followed by the amplier. This
is because the power surge in the Fono could cause an audible power on “thump”
which may distress the speakers.
