Rega Fono MkII Moving Magnet Phono Stage

The new Rega Fono MM is a moving magnet disc stage which has been designed to be effective, easy to use and above all reproduce music. The Rega Fono MM's new surface mount board layout has been optimised to work with the latest generation of RP turntables. The Rega Fono's compact design now housed in a Rega's new style case to aesthetically match Brio-R, Apollo-R and the DAC offers performance way beyond that expected at this price point and makes an excellent addition to any vinyl based system.

  • New edition of Rega's already popular Fono MM phono stage
  • Surface mount board layout has been optimised to work with the latest generation of RP turntables
  • Compact design now housed in a Rega's new style case to aesthetically match Brio-R, Apollo-R and the DAC
  • Offers performance way beyond that expected at this price point
  • Excellent addition to any vinyl based system

Why do I Need A Separate Phono stage / Pre Amplifier with my Turntable?

RIAA equalisation is a form of pre-emphasis on recording and de-emphasis on playback. A recording is made with the low frequencies reduced and the high frequencies boosted, and on playback the opposite occurs. The net result is a flat frequency response, but with attenuation of high frequency noise such as hiss and clicks that arise from the recording medium. Reducing the low frequencies also limits the excursions the cutter needs to make when cutting a groove. Groove width is thus reduced, allowing more grooves to fit into a given surface area, permitting longer recording times. This also reduces physical stresses on the stylus which might otherwise cause distortion or groove damage during playback.

A potential drawback of the system is that rumble from the playback turntable's drive mechanism is amplified by the low frequency boost that occurs on playback. Players must therefore be designed to limit rumble, more so than if RIAA equalization did not occur.

RIAA equalization is not a simple low-pass filter. It defines transition points in three places: 75 µs, 318 µs and 3180 µs, which correspond to 2122 Hz, 500 Hz and 50 Hz (rounded values). Implementing this characteristic is not especially difficult, but is more involved than a simple amplifier. In the past, almost all hi-fi preamplifiers, integrated amplifiers, and receivers had a built-in phono preamplifier with the RIAA characteristic, but it is often omitted in modern designs, due to the gradual obsolescence of vinyl records. Add-on phono preamplifiers with the RIAA equalization curve are available; these adapt a magnetic phono cartridge to an unbalanced −10 dB consumer line-level RCA input. Some modern turntables feature built-in preamplification to the RIAA standard. Special preamplifiers are also available for the various equalisation curves used on pre-1954 records.
