Rega Fono MC MK4

The Fono MC MK4 is a high-quality phono stage to maximize the potential of low-output MC cartridges, offering full adjustability for gain and loading. Its redesigned case matches the Fono MM MK5 and Neo MK2 for a modern look. It uses the Linear Systems LSK389 FET for a low-noise, linear input stage, with a high input impedance so the amplifier won’t affect cartridge performance.

Output Impedance-200 Ω

Recommended Minimum Output Load Resistance-5 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

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
