Rega Fono MC Mode D'emploi page 3

introduction /
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.

powering up /
The Fono MC is turned on by pressing the on-off 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 first followed by the amplifier. This
is because the power surge in the Fono could cause an audible power on "thump"
which may distress the speakers.
method of connection /
INPUT: Connect the tonearm leads and earth (if used) to the input socket and to
the earth terminal on the back of the Fono.
Input Loading DIP Switch Settings (located on rear panel):
Loading resistance
1 and 2 off = 400Ω
Turntable Earth:
1 on = 100Ω
If the turntable or tonearm has a separate
2 on = 150Ω
signal earth connection, this should be
1 and 2 ON = 70Ω
connected to the turntable earth terminal on
the back of the unit.
Capacitance
3 off = 1000pF
OUTPUT:
3 on = 4300pF
Connect the output socket of the Fono to the
line input on the amplifier.
Gain
4 off = 63.5dB Please note: If you have an integrated amplifier with built in
4 on = 69.5dB phono stage, DO NOT connect the Fono to this input.
