The FONO MC MK4 is a dedicated moving-coil phono preamplifier from Rega, built with a wide bandwidth specifically optimised for MC cartridge output levels. The FONO MC MK4 brings Rega's considered engineering to a specialist MC phono format.

Key specs that matter

One single-ended input is provided. MC current-sensing input impedance is 500 ohms, with output impedance at 200 ohms. Frequency response spans a wide 13Hz to 100,000Hz within plus-or-minus 3dB - a remarkable bandwidth for a dedicated phono stage.

Sound and use context

Expect clean, accurate RIAA equalisation reflecting the wide 13Hz-100kHz bandwidth, specifically optimised for moving-coil cartridge output levels and loading requirements.

Pairing

The 500-ohm MC input impedance suits a wide variety of moving-coil cartridges with this specific loading requirement.

Alternatives

Rega's own FONO MM MK5 offers a dedicated moving-magnet alternative within the same broader phono-stage catalogue for buyers with an MM cartridge instead.
