Fono Knows Moving-Coil Cartridges: U.K.-Made Rega Fono MC Mk4 Features All-Discrete Input Stage, MUSE Op Amp, and Selectable Input Loading Options
Only need MC ability with your phono preamplifier? Put the Rega Fono MC Mk4 on your short list. Configured with a Linear Systems LSK389 FET in an all-discrete input stage, MUSE operational amp in the RIAA equalization amplifier, and polypropylene capacitors in the signal path and RIAA equalization circuits, Fono MC Mk4 delivers through-and-through audiophile performance marked by low noise, high linearity, and exceptional clarity. And it gives you options. Selectable input loading for resistance and capacitance — along with two different gain settings — on the back panel gives you the freedom to change cartridges as you desire with the knowledge they’ll jibe with your system. An elegant aluminum case, compact dimensions, and U.K. build quality round out the latest iteration of what’s been a go-to model for more than a decade.

Output Impedance: 200 Ω
Recommended Minimum Output Load Resistance: 5 k
Frequency Response (50 kΩ Output Load): 13 Hz (-3 dB) to 100 kHz (-0.3 dB)
RIAA Accuracy (50 kΩ Output Load): Better than ±0.2 dB 100 Hz to 100 kHz
Power Requirements: 24 V AC at 150 mA maximum
Load settings for adjustable MC stages:
Input Sensitivity (for 200 mV Output): 4 off = 133 uV / 4 on = 67 uV
Input Loading Resistance: 1 and 2 off = 400 Ω / 1 on = 100 Ω / 2 on = 150 Ω / 1 and 2 on = 70 Ω
Input Loading Capacitance: 3 off = 1000 pF / 3 on = 4300 pF / Gain (at 1 kHz) / 4 off = 63.5 dB / 4 on = 69.5 dB
Maximum Input Level (at 1 kHz): 4 off = 6.7 mV / 4 on = 3.4 mV
Factory settings for all Rega MC cartridges: Impedance 100 Ω / Capacitance 1000 pF / Gain Setting High
