REGA Fono MC Mk4

The Fono MC is designed to maximise the potential of any MC cartridge.

Although designed specifically to compliment Rega’s 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.

Technical Specification

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.

Output impedance = 200Ω
Recommended minimum output load resistance = 5K
Frequency response (50KΩ output load) = 13Hz (-3dB) to 100KHz (-0.3dB)
RIAA accuracy (50KΩ output load) = Better than +/-0.2dB 100Hz to 100KHz
Power requirements = 24V AC at 150mA maximum. Only to be used with Rega PS1.

Input sensitivity (for 200mV output)
4 off = 133uV
4 on = 67uV

Input loading resistance
1 and 2 off = 400Ω
1 on = 100Ω
2 on = 150Ω
1 and 2 on = 70Ω

Input loading capacitance
3 off = 1000pF
3 on = 4300pF
Gain (at 1KHz)
4 off = 63.5dB
4 on = 69.5dB

Maximum input level (at 1KHz)
4 off = 6.7mV
4 on = 3.4mV
